  • include main frame(16), main frame (16) is connected by data line grasp shoot device (18), display device (17) and communicator (19);

    DescribedGrasp shoot device (18) includes shooting platform (1), and the side of shooting platform (1) is provided with upright support chuck (2), and upright support is pressed from both sidesIt is provided with up and down support (3) in set (2), between upright support chuck (2) and up and down support (3), is provided with up-down adjustment dressPutting, the top of described up and down support (3) connects has horizontal supporting plate (4), horizontal supporting plate (4) one end to be provided with image acquisitionDevice (8);

    Described display device (17) is provided with photographic head (20);

    Described communicator (19) is provided with Audio Input Modules and soundFrequently output module;

    Described main frame (16) includes CPU, CPU and is provided with power interface, video sampling and compressing Processing Interface, displayDevice HDMI, network interface and audio decoder;

    Described video sampling and compressing Processing Interface and described grasp shoot device (18)On image acquisition device (8) and photographic head (20) in display device (17) connect, described display device HDMI and instituteStating display device (17) to connect, described audio decoder connects has recording module A, recording module A connection to have sound output interfaceAudio Input Modules and sound with sound input interface, voice output interface and sound input interface and described communicator (19)Frequently output module connects;

    The audio, video data that described main frame (16) receives, is carried out data transmission by network interface, and main frame (16) is as packetSender, is divided into packet by audio, video data and is transmitted, and described data packet sending method is as follows;

    A, packet sender initialize one and send data buffering queue, and packet inserts buffering team from afterbody while sendingRow, wait the confirmation bag of these data, after receiving confirmation bag, delete the data in buffer queue;

    During B, packet reciever process data, receive a packet generation one and confirm that bag is put into confirmation and wrapped teamRow, the timing of packet reciever sends one and confirms that package closes packet;

    C, packet reciever at the beginning when can according to rule initialize one expectation accept packet number, if acceptTo the serial number that carried of packet be more than expected packet number, then data pack buffer can be got up, until itsPacket is submitting upper strata to after arriving in the lump, and for the packet lacked, reciever can initiate a NAK, asks senderPacket required for transmission.
