Fig. 1 is a flowchart illustrating a method for voice browsing, selecting channels and/or programs according to an embodiment of the present invention. The method for browsing and selecting the channel and/or the program by voice comprises the following steps:
step 100: the start, i.e., the starting point and starting time, of the method of voice locating channels and/or programs.
Step 101: and starting initialization of the set top box. And when the set-top box is started to initialize or after the set-top box is initialized, the set-top box terminal downloads the program menu sent by the server. The program menu includes all programs provided by the server when downloading is finished. However, each program contains two files: text information files and voice information files. The text information file contains program name, playing time and the like, the voice information file contains voice data for broadcasting text information, and the contents of the text information file and the voice information file are in one-to-one correspondence. The set-top box terminal acquires the channel and program information in the following way: acquiring channel list information from a server when entering a playing system; or acquiring the program information of the page when entering the on-demand page; or obtaining the file list information in the folder from the file system. The program information includes a program name, the channel information includes information such as a channel name, and the channel information may include information of different languages, such as a chinese name or an english name, according to different supported index rules. In addition, after acquiring the channel and/or program information, the set-top box extracts the corresponding information from the word stock, and creates different index lists according to the supported index rules, wherein the index lists can be created when acquiring the channel and/or program information, and can also be temporarily created when using searching. The set-top box is only a special example of the embodiment, and the digital television receiving terminal of the invention comprises all devices with the function of receiving digital televisions.
Step 102: the set-top box starts the voice positioning system. The voice positioning system of the set-top box can be started by default, namely the voice positioning system is started while the set-top box is started; in addition, the voice positioning system of the set-top box can also be manually started after the set-top box is initialized, namely, the voice positioning system is started by using a remote control key. That is, the set-top box starts the voice positioning mode and prompts the user to input the voice command before the set-top box acquires the voice command. And after the set-top box starts the voice positioning system, the set-top box is automatically muted.
Step 103: the user inputs a voice command. In the embodiment of the invention: voice commands fall into two categories, one being command commands and the other being keyword commands. Wherein, the command instruction is a control instruction input by a user, such as: an instruction for starting a voice positioning program format, an instruction for exiting the voice format, an instruction for selecting a program, an instruction for re-inputting keywords and the like. The keyword instruction refers to keywords of channel and/or program information input by the user voice, and the channel keywords are as follows: "CCTV 1", "hennan satellite view", "Shenzhen satellite view", etc., and the program information keywords are as follows: "No future of the thief", "love of hawthorn tree", "wild rose in Paris", "past in the United states", etc.
Step 104: and recording a voice command of a user by a recording program in the set top box, and automatically recovering from silence by the set top box.
Step 105: and taking the output result of the recording program as input, and calling the voice recognition program to decode the voice command of the user. The voice recognition program in the voice decoding module receives a voice command, and the voice command is input into the voice recognition program by the recording program. And a voice recognition program in the voice decoding module receives the voice command and then analyzes the voice command into character information, and the characteristics of the character information are extracted. Then, in the subsequent step, whether the voice information is a command instruction or a keyword instruction is identified, and the specific information of the voice instruction is determined.
Step 106: it is determined whether it is a command instruction. Step 106 is divided into two cases: if the judgment result is positive, executing step 107; and secondly, the judgment result is negative, namely the command input by the user is not a command instruction, and if the command input by the user is a keyword instruction, the step 108 is executed.
Step 107: the set-top box executes command instructions input by a user, such as: an instruction for starting a voice positioning program format, an instruction for exiting the voice format, an instruction for selecting a program, an instruction for re-inputting keywords and the like.
Step 108: the set-top box searches programs containing the keywords in the existing program list, namely the set-top box searches channels and/or programs matched with the decoded text information in an index list according to the decoded text information; if the set-top box does not find the program or channel matched with the input voice information, displaying the list as empty and prompting the user to enter a new keyword instruction from the list or to enter a command instruction for voice prompt from the list to quit the search, and the like; and the set top box finds out the program or the channel matched with the input voice information, displays the searched channel and/or program list and broadcasts the channel and/or program in a voice mode, and prompts a user to select the required channel and/or program information in a voice mode. Wherein, the keyword instruction refers to the keyword of the channel and/or program information input by the user voice, and the channel keyword is as follows: "CCTV 1", "hennan satellite view", "Shenzhen satellite view", etc., and the program information keywords are as follows: "No future of the thief", "love of hawthorn tree", "wild rose in Paris", "past in the United states", etc. The command instructions include, but are not limited to, an instruction to turn on a voice located program format, an instruction to exit a voice format, an instruction to select a program, and an instruction to re-enter a keyword.
Step 109: the set-top box identifies whether a program containing the keyword exists in the existing program list. The set-top box takes the decoded text information as a keyword, and searches a channel and/or a program matched with the current keyword (the text information decoded by the input voice instruction) from a current program list (the acquired channel and/or program list) according to a matching rule. If there is no channel and/or program containing the keyword in the existing program list, step 110 is executed: the set-top box prompts the user to input a keyword instruction. If there is a channel and/or program containing the keyword in the existing program list, step 111 is executed: and the set top box broadcasts the search result. The searching result is that all channels and/or programs in the existing program menu contain input keywords, each channel and/or program has a program serial number, and all searched channels and/or programs contain text information files and voice information files, namely a program set sent by a television station when a set top box is initialized.
Step 110: the set-top box prompts the user to input a keyword instruction. After the user inputs the keyword command, step 108 is executed: the set-top box searches the programs containing the keywords in the existing program list.
Step 111: and the set top box broadcasts the search result. The searching result is that all channels and/or programs in the existing program menu contain input keywords, each channel and/or program has a program serial number, and all searched channels and/or programs contain text information files and voice information files, namely a program set sent by a television station when a set top box is initialized.
Step 112: the set-top box waits for the user to input a voice command. In step 111, all channels and/or programs in the existing program menu including the input keywords appear on the tv screen controlled by the set-top box, and each channel and/or program has a program number, and all searched channels and/or programs include text information files and voice information files. For example, if the keyword input by the user is "CCTV", all program listings containing the keyword "CCTV" appear on the tv screen controlled by the set-top box, such as: "1. CCTV 1", "2. CCTV 3", "3. CCTV 6", "4. CCTV 9", "5. CCTV 7"; if the keyword input by the user is 'love of hawthorn tree', all program lists containing the keyword 'love of hawthorn tree' appear on a television screen controlled by the set-top box, such as: "1. love of hawthorn tree". In addition, each program contains two files: text information files and voice information files. The text information file contains program name, playing time and the like, the voice information file contains voice data for broadcasting text information, and the contents of the text information file and the voice information file are in one-to-one correspondence. Therefore, the searched channels and/or programs are displayed on the television screen controlled by the set-top box, and the set-top box voice broadcasting module can broadcast the searched channels and/or programs simultaneously. For example, if the keyword input by the user is "CCTV", all program listings containing the keyword "CCTV" appear on the tv screen controlled by the set-top box, such as: "1. CCTV 1", "2. CCTV 3", "3. CCTV 6", "4. CCTV 9" and "5. CCTV 7", meanwhile, the voice broadcast module of the set-top box broadcasts: CCTV1, 2.CCTV3, 3.CCTV6, 4.CCTV9, 5.CCTV 7. If the keyword input by the user is 'love of hawthorn tree', all program lists containing 'CCTV' keywords appear on a television screen controlled by the set-top box, such as: "1, the love of hawthorn tree" simultaneously, the voice broadcast module of STB can report: 1. love of hawthorn tree.
Step 113: the user enters voice command instructions. After the step 112, if the keyword input by the user is "CCTV" and the user wants to watch "CCTV 3", the channel CCTV3 can be selected by inputting the serial number "2" through the voice input device. In addition, the user can also directly input the keyword command "CCTV 3" by using the voice input device in step 112, and then all program lists containing the keyword "CCTV 3" appear on a television screen controlled by the set-top box, namely, "1.2010 a 9 th 19 th CCTV3 news simulcast", "2.2010 a 9 th 19 th CCTV3 a focus visit". 9 th 19 th 3 th CCTV3 news simulcast in step 113, the user can select 2010 a 9 th 19 th date CCTV3 news simulcast by using the voice input device to input the sequence number "1", and the set-top box downloads and plays 2010 a 9 th 19 th date CCTV3 news simulcast according to the result selected by the user. If the keyword input by the user is ' hawthorn tree love ', all program lists ' 1 including the keyword ' hawthorn tree love ' appear on a television screen controlled by the set-top box, the ' hawthorn tree love ' can be selected by directly inputting a sequence number ' 1 ' in the voice input device after the broadcasting in the step 112, and the set-top box downloads and plays the ' hawthorn tree love ' according to the result selected by the user.
Step 104: after the user finishes watching the program, step 104 is executed, the execution command instruction is selected to close the set top box or the keyword instruction is selected, the favorite program is continued, and the steps are repeated in a circulating way.
