The present invention relates to a streaming service, and more particularly, to an apparatus and method for providing a streaming service using an internal buffer suitable for improving the efficiency of memory utilization by using an internal buffer when performing a streaming service to a terminal. .

In general, streaming refers to a technology for reproducing voice, video, animation, etc. in real time on the Internet. It is a technology that downloads and plays video, sound, and animation files from the Internet to a hard disk drive and plays them in real time without downloading them. It is called 'streaming' because data is processed as if water is flowing. It is named.

Even before all the files are transferred, the client browser or plug-in will begin to present the data.

Therefore, the play time is shortened and the capacity of the hard disk drive is hardly affected. For streaming to work, the client side receiving the data must be able to collect the data and send it to an application that converts the data into a sound or picture.

If the client receives data too fast, it will store the extra data in a buffer and stream it at the same time. However, if the data reception speed is not fast, the representation of the data is not smooth.

1 is a block diagram of a video mail service system for a mobile communication terminal as an example of a conventional streaming service providing apparatus.

Here, reference number 1 uses a mobile communication service, 1 is a terminal, 2 is an SMS server connected to the terminal 1 through a mobile communication network to provide a short message service, and 3 is a terminal 1 through a mobile communication network. WAS (Web Application Server) server connected to the terminal 1 to perform a web connection, 4 is a multimedia streaming server (MSS) server for transmitting a large file to the terminal 1 through a mobile communication network It is a streaming server, and 5 is a network attached storage (NAS) that provides content to a streaming server.

2 is a flowchart illustrating a conventional streaming service providing method.

It is determined whether the terminal 1 requests the streaming service of the specific content from the streaming server 4 (ST1).

If the terminal 1 requests the streaming service of the specific content from the streaming server 4, the NAS 5 loads the memory to the streaming server 4 (ST2).

The streaming server 4 then determines whether the memory capacity is full (ST3).

If there is excess memory capacity, a large amount of content is downloaded from the streaming server 4 to the terminal 1 through the set call of the terminal 1 (ST4).

If there is no excess in the memory capacity, the call is rejected and the terminal 1 cannot download a large amount of content from the streaming server 4.

3 is a conceptual diagram illustrating an example in which a call is rejected in FIG. 2.

In the application of the MSS server, which is the streaming server 4, the memory processing algorithm of the content is not optimized, causing a problem in which a call is rejected due to insufficient memory available when a plurality of large content service requests are made.

By loading all the requested contents into the memory, a memory shortage occurs when a service request for a plurality of large contents is requested.

For example, a memory size that can be accessed by one application is 4GB (32bit O / S, 2 ^ 32 = 4GB), and the cache memory has a size of at least 3GB (gigabyte). The memory capacity for content loading and application local variables ranges from 4GB of total memory capacity to 1GB, excluding 3GB of cache memory capacity.

However, large contents such as dramas and movies range from 0.7 GB to 1.37 GB per piece. Even when this is edited for a mobile communication terminal, it is 50-100 MB per piece.

In this way, the content becomes large, but there is a problem that a call may be rejected because a newly incoming call fails to load the requested content in the memory when memory resources are insufficient.

The present invention has been proposed to solve various problems in the related art.

An apparatus and method for providing a streaming service using an internal buffer according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, when it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intention or precedent of a user or an operator, and thus, the meaning of each term should be interpreted based on the contents throughout the present specification. will be.

First, the present invention is intended to improve the efficiency of memory utilization by using an internal buffer when performing a streaming service to a terminal.

In addition, although the conventional structure of loading and caching the entire metadata and contents into the memory, the present invention improved the content memory processing algorithm in the streaming server 40 by changing the structure to load and load only the metadata in the memory.

Here, meta data is structured data about data and refers to data that describes other data. Such metadata is also called attribute information. It is data that is given to content according to a predetermined rule in order to efficiently find and use information that is being searched among a large amount of information.

Here, the location and contents of the content, information about the author, the conditions of rights, the conditions of use, the history of use, etc. are recorded. Computers usually use metadata to express data and to find data quickly.

The best example of metadata used to represent data is the HyperText Markup Language (HTML) tag. Structuring data is like having a head or body inside an HTML tag, a table inside a body, a tr inside a table, and a td inside a tr. It means that the tree is formed from the top to the bottom.

Another purpose of meta data is to find data quickly, which serves as an index of information on a computer. The user can easily find specific data (information) desired by the search engine using meta data.

Metadata can be used to extract data from actors from a scene in a movie, or to extract only a goal shot from a video of a football match, and to edit these materials.

In the former or latter case, the metadata is invisible to the person using the data. But machines (computers) understand the content of metadata and use it. In other words, the machine understandable information about web material or anything else is metadata.

Thus, a search method using metadata, which has recently been popularized, helps users to search for desired content more conveniently and quickly. For example, if an MP3 file contains information such as genre, author, song name, and album name with ID3 tag, a kind of metadata, sort each music file by author or album instead of simply showing the file name. This allows users to browse files by author or album.

In this case, the ID3 tag is a format used to add information such as a song name, author, and music channel to a Moving Picture Experts Group (MPEG) Layer 3 (MP3) file.

Therefore, the streaming server 40 loads and caches only metadata in a manner of loading and caching the metadata and the entire content of the memory processing method of the streamed requested content, and the actual content is 512KB for audio and video data for each user. By changing to a service structure using a memory buffer, a problem of rejecting a new transaction due to physical limitations of the memory has been improved.

In addition, by improving the memory usage problem in proportion to the size of the content requested content, the processing capacity in the system can be significantly improved. For this reason, the maximum memory usage per user is 2MB by using two 512KB buffers and redundancy them.

4 is a block diagram of a streaming service providing apparatus using an internal buffer according to an embodiment of the present invention.

The terminal 10 downloads content through the streaming server 40 and uses a streaming service.

In addition, the RTP WAS (Realtime Transport Protocol Web Application Server) 20 is a terminal of the server accepting the content information, which is the information for the terminal 10 to access the streaming server 40 to receive the streaming service, the subscriber station number of the terminal 10 It downloads IP (Internet Protocol) information to the terminal 10.

In addition, the content information management server 30 receives the content information, which is information for receiving the streaming service from the RTP WAS 20, and the IP (Internet Protocol) information of the server that accepts the subscriber station number of the terminal 10, and is managed. The information of the content is transmitted to the RTP WAS 20.

In addition, the streaming server 40 loads and caches metadata of the content information, prepares a streaming service using a buffer of the actual content, and if the terminal 10 requests the streaming service, the streaming service of the content to the terminal 10. To provide.

Caching refers to the temporary storage of instructions and data in cache storage or disk cache.

Caching allows the server's processor to improve server performance by speeding up or near the speed of the processor several times faster than reading instructions and data from memory or disk, or writing data to memory or disk.

In the streaming server 40, the processor 41 controls the streaming service operation of the streaming server 40 and is configured with redundancy.

The task thread 42 is under the control of the processor 41, processes the content streaming request of the terminal 10, retrieves the cache of the cache memory 43, and sends the content to the content using a cache thread 44. Request a cache for

When the cache thread 44 receives a cache request from the task thread 42, the metadata and actual content of the contents of the NAS 50 are loaded into the cache memory 43.

The cache memory 43 loads metadata about content from the NAS 50, caches and loads content from the NAS 50, and downloads the cached content by streaming from the terminal 10.

The cache memory 43 loads the content data into the current buffer and the next buffer set for each track when the actual content is loaded from the NAS 50 and starts streaming to the terminal 10, and the buffer is started. It loops through and loads the content data into the next buffer to continue streaming.

In addition, NAS (Network Attached Storage) (50) provides the content to the streaming server (40). The NAS 50 is a network-attached storage (storage), and is a file server specialized to be connected to a network.

It uses traditional LAN (Local Area Network) protocols such as Ethernet or Transmission Control Protocol / Internet Protocol (TCP / IP), and UNIX's Network File System (NFS). It handles file I / O requests such as and Server Message Block (SMB) in DOS / Windows.

Thus, the NAS 50 is a network-attached storage capable of sharing data between connected host systems. NAS was originally proposed to share data in LAN environments, integrating file system functionality into storage devices.

In a NAS environment, servers connect to storage systems through standard Ethernet networks and request storage using standard file access protocols such as NFS and Common Internet File System (CIFS). Local file system calls sent by clients are redirected to NAS 50, which provides shared file storage for all clients.

If the client is a desktop, the NAS 50 presents the file without the server, and if the client is a server system, the NAS 50 provides the file to the server.

When the Open Contents command is transmitted from the cache thread 44 of the streaming server 40 to the NAS 50, the NAS 50 sends the metadata and the actual content to the cache memory 43 of the streaming server 40. Will be provided.

5 is a flowchart illustrating a streaming service providing method using an internal buffer according to an embodiment of the present invention.

First, the streaming server 40 loads and caches only meta data, and prepares a streaming service using a buffer using actual buffer (ST11).

In the conventional method, as shown in FIG. 6, the header information, audio, and video information of the content are simultaneously loaded and cached into a memory. Use to load immediately to prepare streaming service.

As shown in FIG. 7, the streaming server 40 separates the general streaming content and the real-time broadcasting content by using the idle equipment. In other words, in MSS # 1 ~ 4, live broadcasting (KBS1, KBS2, SBS, MBC, adult broadcasting, etc.) service is separated into a separate system (Live # 1) and memory of general VOD (Video on Demand) streaming process This can reduce the frequency of transaction rejection problems caused by the memory pool.

As shown in FIG. 8, the streaming server 40 manages a redundant process for a general streaming service. That is, by minimizing the memory pool phenomenon and improving the processing capacity, the process for the general VOD streaming service of MSS # 1 ~ 4 can be duplicated. The limit memory per process can be set to 4GB.

When the terminal 10 requests a streaming service of a specific content (ST12), the RTP WAS 20 performs the distributed processing for each content so that the terminal 10 downloads the content from the streaming server 40 (ST13).

As shown in FIG. 9, the same content is stored in another MSS in the streaming server 40 by distributed processing based on content ID. By applying the content-based distributed processing algorithm of the RTP WAS 20 to increase the cache hit (Hit) rate of the MSS and improve the efficiency of memory resources.

Therefore, the prefix routing method in which the streaming server is designated by the conventional subscriber station number is changed to change the distributed processing method by the content ID. Accordingly, the same content is not repeatedly stored in the memory of each server, thereby improving the efficiency of memory usage.

Service requests for the same content are streamed on the same server to improve the cache hit rate.

FIG. 10 is a detailed flowchart illustrating an example of distributed processing for each content in the RTP WAS in FIG. 5, and FIG. 11 is a conceptual diagram illustrating the operation of FIG. 10.

The RTP WAS 20 determines whether the terminal 10 requests a streaming service of a specific content (ST21).

If it is determined that the terminal 10 requests the streaming service of the specific content, the RTP WAS 20 uses the content information management server 30 to access the streaming server 40 to receive the streaming service. It requests the content information, which is the information, and the IP information of the server that accepts the subscriber station number (ST22).

The content information management server 30 lowers the IP of the server accommodating the content information and the corresponding station number to the RTP WAS 20 (ST23).

The RTP WAS 20 transmits information to access the streaming server 40 to the terminal 10. As in the prior art, when the routing process is performed for each subscriber station number, the same content may be simultaneously serviced by four systems, and a large amount of content may be concentrated in one system at a specific time.

Thus, in the present invention, by performing the routing process based on the content information retrieved from the content information management server 30, the specific content is serviced only in the same one system to increase the cache hit rate, the service request of large content This prevents concentration on the system (ST24).

The terminal 10 accesses the designated streaming server 40 to download specific content (ST25).

12 is a flowchart illustrating the overall operation of a streaming service providing method using an internal buffer according to an embodiment of the present invention.

The terminal 10 makes a content streaming request to the task thread 42 of the streaming server 40 (ST31).

The task thread 42 of the streaming server 40 receives this, and searches the cache memory 42 (Search Cache) (ST32).

The task thread 42 makes a request cache to the cache thread 44 (ST33).

The cache thread 44 of the streaming server 40 requests (Open Contents) content from the NAS 50 (ST34).

The cache memory 43 of the streaming server 40 loads metadata from the NAS 50 (ST35).

The cache memory 43 loads the content data from the NAS 50 into a current buffer and a next buffer set for each track (ST36).

The streaming server 40 causes streaming to the terminal 10 to start (ST37).

The streaming server 40 continuously circulates the buffer of the cache memory 43 and loads the content data in the next buffer to continuously perform streaming (ST38 to ST40).

As such, the present invention improves the efficiency of memory utilization by using an internal buffer when performing a streaming service to a terminal.

As described above, an apparatus and method for providing a streaming service using an internal buffer according to the present invention have an effect of improving the efficiency of memory utilization by using an internal buffer when performing a streaming service to a terminal.

Therefore, the present invention can transfer a large number of files with memory resources of the same capacity, and the disk input / output for loading a large file can be significantly reduced.

Although the above has been described as being limited to the preferred embodiment of the present invention, the present invention is not limited thereto and various changes, modifications, and equivalents may be used. Therefore, the present invention can be applied by appropriately modifying the above embodiments, and such applications also fall within the scope of the present invention as long as they are based on the technical idea described in the following claims.
