The utility model content
While for above-mentioned existing a plurality of meetings field point, carrying out multipoint conference, a plurality of network nodes place often needs a plurality of MCU terminal equipments to carry out simultaneously mutual communication to complete a plurality of meeting field points, thereby cause MCU terminal equipment complicated layout, override to safeguard the problem of the shortcomings such as inconvenience, the utility model provides a kind of high definition set top box video conference terminal.
For achieving the above object, the high definition set top box video conference terminal that the utility model provides solves problem by following technical essential: the high definition set top box video conference terminal, comprise high definition video collecting card, codec chip, described codec chip is connected on the high definition video collecting card, also comprise the MCU with a plurality of serial line interfaces, described MCU also comprises bus transceiver and message handler, described bus transceiver is connected with message handler with codec chip respectively, and described a plurality of serial line interfaces are connected with message handler respectively.
MCU with a plurality of serial line interfaces is used for connecting the terminal equipment of each branch's video conference place, MCU utilizes built-in message handler to encode after receiving each sub-venue signal, send in codec chip and descend the coded program of encoding according to certain form together by bus transceiver again, information flow after coding enters the high definition video collecting card finally, finally completes the collection of each sub-venue high definition video and acoustic information stream and collects work; The high definition set top box video conference terminal is carried out above-mentioned opposite operation to the information data that each sub-venue sends.
Preferably, described a plurality of serial line interface is RS-232 interface.RS-232 interface is the communication interface of computer standard configuration, is convenient to the terminal equipment of MCU and each branch's video conference place, and simultaneously, RS-232 interface can be checked the data of serial ports by hyper terminal, and PC easy to use detects analysis to circuit.
Preferably, described high definition video collecting card is the HDMI capture card.The HDMI capture card is supported on the single line cable and transmits, without digital high definition, multichannel audio and the intelligent format of compression and the digital interface of control command data, simultaneously, the HDMI capture card have high stability, multi-functional, compatible wide, the characteristics such as secondary development bag SDK are provided.
Preferably, described codec chip is TW2880 high definition chip.TW2880 can accept 16 road D1 inputs and the 16 road D1 of playback simultaneously simultaneously, and exports simultaneously 16 road D1 to the rear end compression chip, has advantages of that encoding and decoding speed is fast and efficiency is high.
Further, described MCU also comprises address decoder, and described address decoder is connected with bus transceiver.The address compilation device that arranges is intended to after address decoder Input Address control signal, and address decoder provides the address of appointment so that bus transceiver has reading of target and distribute data to bus transceiver.
Preferably, described message handler is 8031 processors.Meeting under the prerequisite that video data, voice data and simple control signal transmission operational capability are required, embed 8031 mature and stable processors, both can control the cost of MCU, guarantee that simultaneously MCU is stable.
The utlity model has following beneficial effect:
Be provided with the high definition set top box video conference terminal of a plurality of serial line interface MCU, be used for connecting the terminal equipment of each branch's video conference place, realize that single high definition set top box video conference terminal connects the terminal equipment of each meeting-place video conference simultaneously, namely realize a plurality of network nodes of high definition set top box video conference terminal connection, be conducive to reduce the complexity of multipoint conference group network structure, reduce simultaneously the quantity of high definition set top box video conference terminal, be convenient to administering and maintaining of high definition set top box video conference terminal.
