Title:
VIDEO TRANSMISSION SYSTEM HAVING PHYSICAL LAYER RETRANSMISSION AND REAL-TIME TRANSMISSION FUNCTIONS
Document Type and Number:
WIPO Patent Application WO/2023/143506
Kind Code:
A1
Abstract:
Disclosed is a video transmission system having physical layer retransmission and real-time transmission functions. The video transmission system comprises a first transmission terminal, a second transmission terminal and a transmission channel. The first transmission terminal comprises a sending memory; the first transmission terminal stores a retransmittable data packet into the sending memory and sends the retransmittable data packet to the second transmission terminal, the retransmittable data packet comprising a serial number; the second transmission terminal judges an error state of the received retransmittable data packet, and according to a judgement result, generates and sends retransmission control information, the retransmission control information comprising the serial number of the retransmittable data packet; and the first transmission terminal resends, according to the retransmission control information, the retransmittable data packet to the second transmission terminal. The first transmission terminal further sends a real-time data packet to the second transmission terminal, the real-time data packet being used for transmitting a video time sequence control signal; the second transmission terminal receives the real-time data packet sent by the first transmission terminal, and whether the received real-time data packet is correct or not, retransmission control information is not generated.
