Abstract
The invention provides an integrated digital high-definition television application platform adopting an IP (Internet Protocol) technology, which comprises a signal reception sub-system, a signal integration subsystem and a signal conversion subsystem. The signal reception subsystem receives signals of standard-definition or high-definition programs of a satellite television or a wired television and converts a signal source into clear stream digital television signals. The signal integration subsystem combines the clear stream digital television signals settled by the signal reception subsystem into a digital signal. The signal conversion subsystem converts the digital television signals into two modes respectively and transmits the signals. The integrated digital high-definition television application platform adopting the IP technology fully utilizes and optimizes inner wired television and network system resources of hotels and business buildings, so that digital television signals and network television signals with high quality and high code stream are efficiently and smoothly transmitted and played in a local area network.
Description
Technical field
The present invention relates to DTV and IPTV (Internet Protocol Television, IPTV) broadcast field, especially with both combination and the Play System of synchronous transmission.
Background technology
IPTV is an IPTV, is a kind of broadband cabled television network that utilizes, and integrates multiple technologies such as the Internet, multimedia, communication; The brand-new technology of the multiple interactive services that comprises DTV is provided to the domestic consumer.The user can have dual mode to enjoy the IPTV service at home: (1) computer, (2) network machine top box+general television set.The trend that it can adapt to current network develop rapidly well fully effectively utilizes Internet resources.IPTV both had been different from conventional analogue formula cable TV, also was different from classical DTV.Because, traditional and DTVs classics all have frequency division system, regularly, characteristics such as One-to-All Broadcast; Although classical DTV has many technological innovations with respect to simulated television; But the just change of signal form; And the circulation way of not touching media content.
IPTV mainly transmits with the broadband of ADSL form, limited by broadband technology, and the general image quality of IPTV is low, plays not smoothly, uses IPTV to influence user's normal online easily.
Cable digital TV is to realize the easiest in numerous digital television transfer modes also to be the cheapest a kind of mode of cost, to utilize old cable TV transmission network network to transmit, and only needs just can watch at receiving set up box of receiving terminal configuration.Because digital signal is regenerated to signal at the terminal through the transmission back; Thereby guaranteed that the signal quality that cable digital TV receives is the same with front end of emission; Avoid phenomenons such as twill, snowflake to take place, the SD digital signal can reach distinct image quality as the DVD.Cable digital TV is the TV transmission program not only, and powerful information service also is provided, and its adopts bidirectional transfer of information technology, has increased interactive function, makes TV become a kind of economical and practical, interactive media conveniently.The user can open numerous business such as video request program, shopping online, remote teaching, tele-medicine, data transmission, broadcast videography according to self needs.
But some areas cable digital TV slower development can not satisfy the demand of part client to high resolution image.
The cable television digital situation in hotel and commercial building is just relatively more awkward at present, because these places are paid attention to satellite programming and managed watching of program by oneself very much, can't transmit with the satellite programming common network after the cable television digitalization.IPTV also is a kind of selection of this type of client, but its lower image quality do not accepted by a lot of users, so the client can take in when selecting.To different signal sources, television terminal need be set up dissimilar STBs and carry out the signal reception.If laying-out and purchase corresponding STB and certainly will increase investment also is unfavorable for user experience respectively.
Summary of the invention
The present invention to realize that the DTV of high-quality across a network platform is play, and multisignal source program resource is integrated in order to address this problem, makes the optional majority kind of terminal use mode watch abundant more high quality television program.The present invention provides a kind of digital TV front-end system scheme of having realized digital television system and Web TV (IPTV) combination and the synchronous transmission of DVB-C standard, promptly adopts IP technology integrated digital HDTV application platform.
A kind of employing IP technology integrated digital HDTV application platform, form by following subsystem:
The signal receiving subsystem, it receives the satellite television or the cable television program signal of SD or high definition, and changes signal source into the clear stream digital television signal;
The signal integration subsystem, its clear stream digital television signal with the arrangement of signal receiving subsystem is merged into a way word signal;
The conversion of signals subsystem, it changes into dual mode respectively with a way word TV signal and transmits.
Wherein, described dual mode is digital cable TV mode and Ethernet TV mode.
Wherein, the digital cable TV mode is utilized in the cable TV network and is transmitted, and the Ethernet TV mode utilizes local area network (LAN) to transmit.
Wherein, utilize satellite television receiver, digital television receiver and digital encoder reception signal in the signal receiving subsystem and, convert the clear stream digital television signal then into the decrypted signal that receives.
Wherein, it is multiplexing to utilize the IP reuse device that the clear stream digital television signal that receives is carried out in the signal integration subsystem, is integrated into an independent digital television program bag, carries out digital television signal output with ASI form and IP aspect respectively.
Wherein, In the signal transformation subsystem; Multiplexer and IP server are put in order the ASI format signal that receives and IP signal respectively and are sorted out; The signal that two-way is put in order sends to the QAM modulator respectively and switch is changed; Obtain RF radiofrequency signal and IP signal after the conversion respectively, the RF radiofrequency signal is propagated through the DVB DTV STB through the digital cable TV network and is outputed to the television equipment broadcast, and the IP signal is propagated through the computer broadcast or through the IP STB through local area network (LAN) and outputed to the television equipment broadcast.
The present invention makes full use of and optimizes the inside cable TV and the network system resources in hotel, commercial building, make high-quality high code stream digital television signal, the Web TV signal in LAN, efficiently transmits glibly and broadcast is achieved.
