The broadcast card of data broadcasting server has DVB data broadcast standard form, support four kinds of transmission meanss of DVB definition: data pipe (Data Pipe), data flow (Data Stream), multi-protocols encapsulation (MultipleProtocol Encapsulation), data/object carousel (Data/Object Carousel).
The Webpage requesting multi-medium of a kind of unidirectional network of present embodiment is used implementation method, comprises the following steps:
1) makes song audio files, lyrics file or give a lecture original text, meet the webpage (comprising literal and picture) of W3C reference format.
The user preserves after the music program of different audio data format or speech audio files being converted into the data format of Mp2 or Mp1 by the song tools, supports the audio data format of conversion also to comprise other audio format such as CD, MP3, WMA, WAV, RAW.Rhythm according to song, the user can be by manual or automatic mode, the lyrics file that the lyrics text or the lecture original text of input is converted to Karaoke lyrics data form, thereby guarantee on cable television digital set-top box to realize that the lyrics or speech draft show, be complementary with the playing progress rate of song or speech speech; The selecting video file is as the background of KTV song or educational program.
Adopt webpage design and software for composing (as: dreamweaver, photoshop, firework) to make and meet the various webpage literal and the image content of W3C reference format, and the link label that needs the audio or video of user's program request program is set in webpage;
2) with audio program data, the background video input audio frequency controller server that the lyrics relevant with audio programs or speech draft, audio program are shared, by audio frequency controller server program scheduler module, adopt the audio segmentation algorithm, will import that corresponding audio files is cut apart and by the algorithm assigns corresponding bandwidth; Generate playing programs configuration file and audio program data, the background video that the lyrics relevant with audio programs or the text of the speech, audio program are shared sends the data broadcasting server to, is transferred to cable television digital set-top box by broadcast card through hfc plant.
3) but the link label of the above-mentioned specific Voice ﹠ Video program of program request in the literal picture information content of the webpage of the various W3C of the meeting reference formats that step 1 is made and the webpage; Examine sending the data broadcasting server to after errorless, be transferred to cable television digital set-top box through hfc plant by broadcast card.
4) but the link label of the above-mentioned specific Voice ﹠ Video program of program request in the literal picture information content of the webpage of the ETV program additional information that step 1 is made and the webpage; Examine sending broadcast data server to after errorless, the digital television program or the NVOD quasi video frequency request program stream that broadcast through multiplexer and TV station mix after hfc plant is transferred to cable television digital set-top box.
5) set-top box receiving step:
A, as shown in Figure 2 at web page browsing state when showing various webpages and literal picture (simple receive):
Set-top box is resolved the audio frequency of user's program request or the web page interlinkage label of video frequency program,
When the program request audio program, receive the also audio program data of cache user program request immediately; Behind the voice data of the intact first of buffer memory, set-top box is decoded to audio program and is begun and plays, and continues buffer memory simultaneously and plays remaining voice data, up to buffer memory and play audio file, guarantees the continuity of voice playing.
When program request KTV song or educational audio program, on the basis that above-mentioned audio frequency buffer memory is play, need to receive and show the lyrics or the text of the speech and shared background video, guarantee the synchronous of the lyrics or text of the speech information and audio program simultaneously.
When program request NVOD program, according to webpage embedded link parameter tags, search selected NVOD program, after finding, jump to specified channel, displaying video programs; The video programming signal and broadcast of the video wicket in current web page or the full frame decoding broadcast that stop to play current video program and lock user's program request according to the parameter information in the web page interlinkage label.
B is at ETV state (watching reception in the Digital Television and demonstration various webpages relevant with digital television program and literal picture additional information or reception and demonstration and the relevant digital television program of webpage in display web page and literal picture) as shown in Figure 3:
Receive and play digital television program, and relevant supplementary information is searched in search automatically, after inquiring additional information, i.e. display additional information prompting (the available commercial breaks page or other prompting sign)
Program request additional information, set-top box receive and show the webpage of the additional information that meets the W3C reference format;
From Webpage requesting and playing audio-fequency data, KTV song or the educational audio program of additional information, Digital Television or NVOD program step are identical in the described step of web page browsing state with A.Using the same method receives and plays this audio data file, replaces Digital Television audio frequency at that time, or uses the same method and receive and redirect is play KTV song or educational audio program, received and the NVOD program is play in redirect.
The Webpage requesting multi-medium application system of a kind of unidirectional network provided by the invention, comprise cable television digital set-top box and hfc plant, also comprise " transmitting apparatus ", be following server or module (each server can be installed in separately independently on the physical server, also can be used as shared one or several physical server of module):
