Description

[0001] The present invention relates to an apparatus and method for setting a viewing reservation in IPTV,

The present invention relates to a video display device, and more particularly, to a method for setting a program viewing reservation in IPTV and a method for viewing a viewing reservation program.

Conventional TVs transmit contents produced by broadcasters through radio wave transmission media such as terrestrial waves, cable or satellite broadcasts, and users are provided with a service through a television receiver capable of receiving the transmission media .

However, as digital-based digital TV technology has been developed and commercialized in existing analog broadcasting, it is possible to use various types of media such as real-time broadcasting, contents on demand (DDS), games and news Of the contents service to the user.

An example of content service provision using the Internet network is IPTV (Internet Protocol TV). The IPTV refers to transmitting various information services, moving picture contents, broadcasting, and the like to a user's television using a high-speed Internet network.

In the case of the service using the Internet network as described above, unlike general terrestrial broadcasting or satellite broadcasting, bi-directionality can be added, and the user can watch the content service he wants to view at a convenient time.

That is, since the broadcast contents provided in the IPTV do not have a concept of a start time of the corresponding program, they can freely watch their desired program in a desired time zone. At this time, in order to view each broadcast content in the IPTV, A certain amount of time is essential.

In other words, in order to view the broadcast content provided in the IPTV, a buffering time of a predetermined time according to the broadcast program is indispensably required. Therefore, in order to continuously view the broadcast content, a view reservation function is necessarily required.

Therefore, the method of setting the viewing reservation of the broadcasting contents provided in the IPTV is different from the method of setting the viewing reservation of the broadcasting program provided in the conventional general TV, and accordingly, a separate new viewing reservation method for the IPTV broadcasting service is required to be.

The embodiments of the present invention solve the above problems and provide a customized viewing reservation setting function suitable for the characteristics of a broadcasting program provided in IPTV.

The apparatus includes: a network interface unit connected to a service provider through a network and receiving a broadcast program provided from the service provider; An OSD generation unit for generating a guide of a broadcast program received from the network interface unit; A display unit for displaying a broadcast program guide generated through the OSD generation unit; A user interface unit for receiving a request command from a user; And a control unit for determining a viewing reservation order in the order of inputting a program selection signal input from the user interface unit on the broadcasting program guide and setting a viewing reservation of the selected broadcasting program.

Also, a method of setting a viewing reservation in IPTV according to an exemplary embodiment of the present invention includes: displaying a guide of a broadcast program provided from a service provider connected through a network; Receiving one or more program selection signals on the displayed program guide; Determining a viewing reservation order of the selected broadcasting program in the order of inputting the program selection signal; And setting a viewing reservation of the selected broadcasting program in the determined viewing reservation order.

In another aspect of the present invention, there is provided a program viewing method in IPTV, comprising: buffering a broadcast program in order of viewing reservation; Inputting a playback command of a viewing reservation program from outside; Reading the buffered broadcast program; And displaying the broadcast program on the basis of a viewing reservation order of the viewing reservation program.

Also, a method for watching a program in IPTV according to an embodiment of the present invention includes: inputting a power-on command; Determining whether a preset viewing reservation program is present; And selectively displaying a specific menu screen depending on whether the preset viewing reservation program is present or not.

The apparatus and method for setting a program viewing reservation in the IPTV according to the embodiment of the present invention can provide a function of setting a viewing reservation of only IPTV that is different from the existing viewing reservation setting function, The desired broadcast program can be viewed.

In addition, a buffering state of the viewing reservation program is provided so that the user can easily grasp the downloading state of the program in which the current viewing reservation is set, and provides an after-view function of the program in which the viewing reservation has been established The user satisfaction can be improved.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. It should be understood, however, that there is no intention to limit the scope of the present invention to the embodiment shown, and that other embodiments falling within the scope of the present invention may be easily devised by adding, Can be proposed.

Although the terms used in the present invention are selected as general terms that are widely used at present, there are some terms selected by the applicant in specific cases. In this case, since the meaning is described in detail in the description of the present invention, It is to be understood that the present invention should be grasped as a meaning of a non-term.

As shown in FIG. 1, an IPTV system includes a content provider, a service provider, a network provider, and a consumer layer.

The content provider plays a role of providing content to a service provider, and is also called a content provider.

The service provider plays a role of providing services to the subscriber, collects various contents, transforms the signals according to the IP environment, and delivers the modified contents to the user. Here, the service provider may be a virtual entity.

The network provider connects the user and the service provider through the IP network. The transmission system can use various network networks such as an access network or a backbone network.

The user is a layer for receiving contents and receiving broadcasting, such as an IPTV, a set top box, a PC, or an IP phone.

Hereinafter, the concept of IPTV will be described in more detail.

2 shows a characteristic diagram of a system of IPTV.

Referring to FIG. 2, the system layer of IPTV can be broadly divided into a content provider, a service provider, and a consumer.

A content provider is also referred to as a platform provider. These three groups have different roles, and the content provider is a large group that provides all the overall services and data for a broadcast program.

In addition, the service provider transmits multimedia data, and performs maintenance and management of the transmission network so that the content can be received stably by the customer. Further, the service provider provides the infrastructure and the function to transmit the network to the content provider .

The Consumer group plays back the incoming data using infrastructure such as xDSL or cable, reacts promptly to the user's request, and so on.

Most of them are made up of IPTV producers, and they can be divided into IPTV, set top box, PC or IP phone and so on. IP phones are not directly related to IPTV, but if there is IPTV in general, phone services can also be served together.

Here, each of the above groups will be described in detail. First, a content provider group may be a TV station or a radio station that creates a broadcast program.

A TV station means a conventional terrestrial or cable broadcasting station, which can create a program that can be viewed by the user, store it in a digital form, and transmit it. In general, it is intended to allow transmission in various broadcasting formats.

A radio station means a regular radio station, and although it may be a video channel occasionally, it can be said that it operates mostly without a video channel.

VoD, AoD, and MoD services have different characteristics from TV stations and Radio Stations. In other words, in the case of VoD or AoD, I can store desired programs, movies, and music, and then play them. For example, if there is a broadcast program that is not properly watched because there is no time for viewing the current broadcast program, the user can access the site providing the broadcast service and download the file or play the program immediately.

AoD also offers the ability to record audio programs in a difficult or real-time manner.

MoD service is an abbreviation of Music On Demand. This seems to be a function similar to AoD, but the service is likely to be played out by record companies or music publishers by expanding existing web services.

The PF server is a service provider that manages all broadcasting information and location information provided by the content provider in place. This service mainly includes the broadcasting time of the broadcasting station, position information necessary for broadcasting, and information that the user can access.

The EPG service is one of convenient services that enables users to view broadcast programs by time zone and to grasp them by channel. EPG service is a service that is frequently used by TV Guide, so that the program can be automatically installed and executed on the customer side.

The ECG service has all the functions for the user to conveniently use the content information of the content provider and the access server location and access authority. Simply put, it is an electronic program guide (EPG) that gives you detailed information on the content and the ability to easily connect to servers with content.

Portal Server is a Web service provided by each broadcasting station and is connected to a web server of a broadcasting station or a service provider. The role of Portal Server is to search the list of programs provided by each broadcasting station or content providers providing content services, or to view the list.

The service provider provides the stability and bandwidth of the network so that the multimedia data and the broadcast data transmitted from the content provider can be normally transmitted.

Service providers can provide IPTV services using existing cable networks. In this case, it is necessary to change the equipment of the delivery network.

In other words, it is necessary to configure network equipment capable of real-time data transmission and configure the network considering bandwidth to the customer. These devices need to reduce the bandwidth by processing large amounts of multimedia data using Multicast service, which is the basic network service of IPTV.

If the bandwidth can not be secured, the service provider may transcode the multimedia broadcast data from the content provider or the optical cable network in an attempt to secure bandwidth, and then transform the data into MPEG-4 or MPEG-7 format have.

The service provider is required to provide a number of services in order to achieve this, and it is required to provide size NMS (Network Management System), DHCP (Dynamic Host Control Protocol) and CDN service.

The NMS service manages the Delivery Network and the IPTV receiver of the Customer that the Service Provider can transmit to each Customer. That is, by using this service, it is possible to confirm how much traffic is generated for a certain broadcast and in which area the bandwidth is insufficient.

The DHCP service is used to automatically assign IP to the IPTV receiver of the customer and to provide the address of the CDN server. The DHCP service is also a good way to assign IP to a PC in a normal network. The IPTV receiver should be able to connect to the IPTV receiver to allow access to the IPTV receiver when the user first accesses the IPTV receiver.

The CDN service is data provided by the service provider, and when the IPTV receiver is powered on for the first time, the CDN information is received by the service provider while receiving the IP by the DHCP service. This information contains the registration and authentication of users of IPTV operators and the PF information mentioned above.

A customer can have several types of IPTV receivers. For users with ordinary TVs, IPTV STBs can be rented for inexpensive IPTV enjoyment. Service providers can also pay for additional services at low prices and apply for IP phones.

The IPTV receiver basically has a network interface capable of connecting to a network and has an internet protocol, and receives and processes data packets received from the network. In the case of multimedia data, the IPTV receiver can reproduce data on the screen. And the information is received from the server and reacted.

That is, the IPTV receiver must operate in a bidirectional manner to transmit user's requests while processing multimedia data. In addition, the remote control should be provided with buttons for IPTV so that the service can be used well.

Hereinafter, a viewing reservation setting device in the IPTV will be described.

Fig. 3 is a diagram for explaining an apparatus for setting a viewing reservation in IPTV. Fig.

3, the apparatus includes a broadcast receiver 100, a demultiplexer 110, a video signal processor 120, a display 130, a network 130, An interface unit 140, an OSD generating unit 150, a user interface unit 160, a storage interface unit 170, a memory unit 180, and a control unit 190.

A digital broadcast signal is transmitted in the form of a packetized transport stream by time division multiplexing a video signal, an audio signal, and additional data.

The broadcast receiving unit 100 receives an externally transmitted broadcast signal through an antenna and includes a tuner for tuning a broadcast signal having a frequency band corresponding thereto according to a tuning control signal of a controller 190 to be described later, And a demodulator (demodulator) for outputting the broadcast signal of the channel in the form of a transport stream through a VSB (Vestigial Sideband) demodulation process and an error correction process.

The broadcast signal received through the broadcast receiver 100 is demultiplexed into various additional data defined by a video signal, an audio signal, Program and System Information Protocol (PSIP) .

The video data separated through the demultiplexing unit 110 is processed by the video signal processing unit 120 and displayed on the display unit 130.

At this time, the video signal processing unit 120 includes an MPEG-2 decoder and a scaler for converting the video data to a vertical frequency, a resolution, an aspect ratio, and the like, which match the output specifications of the display unit 130.

The display unit 130 is applicable to various types of display modules such as a digital light processing (DLP), a liquid crystal display (LCD), and a plasma display panel (PDP).

The audio signal is processed by a voice signal processing unit (not shown) and output to a speaker. The voice signal processing unit may include an AC-3 decoder.

The additional data included in the additional data separated through the demultiplexing unit 110 is stored in the memory unit 180 through the storage interface unit 170 to be described later.

The memory unit 180 may be implemented by an electrically erasable programmable read-only memory (EEPROM) or the like.

 The user interface unit 160 is a means for receiving a request command from a user, and typically includes an infrared receiver for receiving an infrared signal input through a remote controller or a local key input unit provided on one side of the panel.

The network interface unit 140 receives broadcast programs received from the network. That is, the broadcast program guide including the broadcast program provided from the service provider and the audience information of the broadcast program is received through the network.

The OSD generating unit 150 generates a menu screen for receiving a user's judgment signal in the form of an OSD (On Screen Display).

That is, the OSD generation unit 150 generates a broadcast program guide screen received through the network interface unit 140 and displays the broadcast program guide screen through the display unit.

The control unit 190 performs overall operation control according to a command input from the user interface unit 160.

In addition, the control unit 190 sets a viewing reservation of a broadcast program input through the network interface unit 140. [

That is, the control unit 190 controls the display of the broadcast program guide received from the network interface unit 140 according to a command input through the user interface unit 160.

In accordance with the program selection signal input through the user interface unit 160 on the displayed broadcast program guide, the viewing reservation setting of the selected broadcast program is controlled.

That is, when the program selection signal is inputted from the user interface unit 160, the control unit 190 determines a viewing reservation order of the selected broadcasting program in the order that the selection signal is input.

Here, the viewing reservation order determined in the order of inputting the program selection signal input from the user interface unit 160 can be changed according to a user's request.

Then, the controller 190 sets a viewing reservation of the selected broadcasting program, and buffers the broadcasting program according to the determined viewing reservation order.

That is, the broadcast program is received through the network interface unit 140 according to the determined viewing reservation order, and is stored in the memory unit 180.

At this time, the control unit 190 controls the buffering status information of the broadcast program for which the viewing reservation is set to be displayed according to the user's request.

That is, in order to reproduce the broadcast program reserved for viewing, the broadcast program must be received through the network interface unit 140 and buffered in the memory unit 180. [

Accordingly, the user can confirm the buffering status information of the broadcast program scheduled to be watched so that the current buffering status has progressed and accordingly, the section that can be immediately watched can be confirmed.

That is, as shown in FIG. 4, the buffering status information indicates the buffering status of each broadcast program for which viewing reservation is set.

Herein, the buffering state is one of buffering completion, buffering, and buffering standby, and one buffering state information is displayed for each broadcasting program according to the buffering state currently in progress.

Accordingly, the user can easily grasp the buffering state of each broadcasting program in which the user currently sets the viewing reservation.

The control unit 190 extracts and reproduces a broadcast program buffered in the memory unit 180 according to a program playback signal input through the user interface unit 160.

At this time, as shown in FIG. 5A, on the display screen reproduced through the display unit 130, the progress status information 200 of the broadcast program being watched in addition to the video data of the broadcast program being reproduced is displayed.

Hereinafter, the progress status information 200 of the broadcast program will be described in more detail.

The progress status information 200 of the broadcast program includes a first progress status bar 210 indicating the entire playback period of the broadcast program to which the viewing reservation is set and a second progress status bar 210 indicating a buffering progress interval And a third progress bar 230 indicating a playback interval currently displayed in the buffering progress interval.

The first progress bar 210 indicates a screening interval of the entire program for which the user sets a viewing reservation. That is, if the total display time of the program in which the user sets the viewing reservation is 5 hours, the entire section of the first progress bar 210 means a video playback interval of 5 hours in total.

The second progress bar 220 indicates the information of the buffered period of the programs for which the viewing reservation is set. That is, the broadcast program from the first progress bar 210 to the second progress bar 220 is already buffered in the memory unit 180, The program up to the section where the bar 220 is displayed can be immediately reproduced according to a user's request.

Therefore, the user can perform trick play such as fast forward, rewind, double speed playback, or the like only within the second progress bar 220, which is possible without distinguishing the broadcast programs reserved for viewing.

The third progress bar 230 indicates information of a section currently being reproduced within the second progress bar 220. That is, the location of the third progress bar 230 indicates the location of the current playback section of the entire broadcast section of the broadcast program.

Also, detailed time information 240 of each of the progress bars 210, 220 and 230 is displayed on the progress status information. That is, as shown in FIG. 5B, on the progress status information, the time information of the section during which the current user is currently playing, the time information until the current buffering is completed, and the total running time information of the broadcast program in which the viewing reservation is set Is displayed.

Accordingly, the user can confirm the presentation time information of the entire broadcast program included in the progress status information of the broadcast program, the time information of the currently reproduced section, and the time information of the section where the current buffering is completed, The program can be viewed.

Also, on the first progress bar 210, identification information 300 for identifying a corresponding location for each broadcast program set by the user is displayed.

That is, when the total number of broadcast programs for which the viewing reservation is set is five, the first identification information 310 indicating the ending period of the first ranked broadcast program and the start period of the second ranked broadcast program, Second identification information 320 indicating the ending period of the third-ranked broadcast program, third identification information 330 indicating the ending interval of the third-ranked broadcast program and the start interval of the fourth-ranked broadcast program, The ending section of the fourth ranked broadcasting program, and the fourth identifying information 340 indicating the starting section of the fifth ranked broadcasting program,

Accordingly, the user can easily change the current playing position to the position of the specific broadcasting program desired by the user, using the identification information classified according to the broadcasting program on the second progress bar 220.

As shown in FIG. 5C, the identification information 300 may be displayed as a delimiter. Alternatively, the identification information 300 may be displayed by changing the color of the progress bar on a program-by-program basis. Alternatively, .

As described above, the viewing reservation setting device in the IPTV according to the embodiment of the present invention provides a customized viewing reservation setting function of only IPTV that is different from the existing viewing reservation setting function, The desired broadcast program can be viewed.

In addition, a buffering state of the viewing reservation program is provided so that the user can easily grasp the downloading state of the program for which the viewing reservation is currently set. Further, when the user subsequently sets the viewing reservation, Satisfaction can be improved.

As shown in FIG. 6, the method for setting a viewing reservation in IPTV according to an exemplary embodiment of the present invention receives a broadcasting program guide from a service provider connected through a network (S10).

Then, the received broadcast program guide is displayed (S20).

Then, it is determined whether a selection signal of a specific program is input on the displayed program guide (S30).

If the selection signal of the specific program is input (S30), the viewing reservation order for the selected broadcasting program is determined in the order in which the selection signal of the program is input (S40). That is, the ranking of the first selected broadcasting program from the outside is determined as the first ranking, and the viewing reservation ranking is determined for each of the selected broadcasting programs thereafter. Then, the first priority program is buffered and reproduced first, and the broadcasting programs of the next ranking are buffered according to the buffering state of the first ranking program.

Then, it is determined whether a change order of the viewing reservation order determined in the order of inputting the program selection signal from the outside is input (S50).

When the determined change order of the viewing reservation order is input (S50), the viewing reservation order of the determined broadcasting program is changed according to the viewing reservation order change command inputted from the outside (S60).

In step S70, the broadcasting program is received and stored in the memory unit 180 according to the viewing reservation order determined in step S40 or step S60.

In addition, as shown in FIG. 7, in step S100, the broadcasting program having the viewing reservation is set in the viewing reservation order of the broadcasting program set in the viewing reservation, as shown in FIG.

Then, it is determined whether a playback command is inputted from the outside (S110).

If it is determined in operation S110 that the playback command is input from the outside, the buffered broadcast program is read in operation S120. That is, the broadcast program stored in the memory unit 180 is extracted.

Then, the progress status information of the read program and the program for which the viewing reservation is set is displayed (S130). That is, a first progress bar 210 indicating the entire playback period of the broadcast program in which the viewing reservation is set, a second progress bar 220 indicating a buffering progress period in which buffering is performed based on the entire playback period, Progress status information including a third progress bar 230 indicating a currently displayed playback interval in the buffering progress interval, and an image of the corresponding broadcast program.

In addition, on the progress status information, detailed information for each section and identification information for identifying a corresponding location for each broadcast program set for the viewing reservation on the basis of the first progress bar 210 are displayed.

Then, it is determined whether a trick play command is inputted from the outside (S140).

If the trick play command is inputted from the outside of the determination result S140, the trick play according to the user's request is executed only in the second progress bar 220 in operation S150. That is, according to the buffering progress state of the broadcast program, the trick play according to the user's request is performed only in the section in which the buffering operation is completed.

Then, it is determined whether a display command of buffering status information is inputted from the outside (S160).

If the buffering status information display command is input from the outside of the determination result (S170), the buffering status information for each broadcast program set for the viewing reservation is displayed (S170). That is, buffering status information of buffering waiting, buffering, and buffering completion is displayed for each broadcasting program according to the buffering progress status of the broadcasting program.

In addition, the buffering status information may be displayed automatically when the program is reproduced, such as the program progress status information, or may be displayed together with the video of the program being played back instead of the program progress status information.

In addition, as shown in FIG. 8, in step S200, it is determined whether a power-on command is input from the outside.

If the power-on command is input from the outside of the determination result (S200), it is checked whether a previously-set viewing reservation program exists (S210).

As a result of the check, it is determined whether a viewing reservation program previously set by the user exists (S220).

If the preset viewing reservation program exists prior to the determination result (S220), a menu screen for inquiring whether to continuously view the previously set viewing reservation program is displayed (S230).

In operation S240, it is determined whether a command to view an image is input from the outside on the displayed menu screen.

If it is determined in operation S240 that the viewing command is input from the outside, the program is continuously played back from the point in time when the command was previously played back before the power is turned off in operation S250.

If it is determined in step S220 that the previously set viewing reservation program does not exist or if an instruction to view the content from the outside is not inputted in step S240, the broadcasting program guide provided from the service provider is displayed in step S260. .

As described above, the apparatus and method for setting a viewing reservation in IPTV according to an embodiment of the present invention provides a function of setting a viewing reservation of only IPTV, which is different from the existing viewing reservation setting function, The user can view a desired broadcast program.
