VIDEO SIGNAL ENCODING SYSTEM AND VIDEO SIGNAL ENCODING METHOD FOR NETWORK TRANSMISSION, VIDEO OUTPUT DEVICE AND SIGNAL CONVERSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To efficiently perform encoding using a motion vector, when encoding video signal for network transmission by combining and using AV devices.;SOLUTION: In a video output device 1, a multiplexer 4 multiplexes reference control information, containing at least a motion vector, outputted from a decoder 6 in a blanking term of a video signal decoded by the decoder 6. In a signal conversion apparatus 8, a demultiplexer 9 demultiplexes the reference control information from the blanking term of the video signal inputted from the video output device 1, and a motion vector converter 11 converts the motion vector, in this reference control information into a motion vector, corresponding to an encoding scheme in an encoder 12. The encoder 12 then encodes the video signal for network transmission by using the converted motion vector.;COPYRIGHT: (C)2008,JPO&INPIT
