VIDEO SIGNAL TRANSMISSION DEVICE, VIDEO SIGNAL RECEPTION DEVICE, AND VIDEO SIGNAL TRANSMISSION SYSTEM

摘要

A video signal transmission device (10) includes: a packer (11) which receives a video signal, a sync signal, and a data-enable signal and packetizes the video signal and the sync signal according to the number of bytes of a packet corresponding to the number of gradation bits of the video signal so as to generate a plurality of packet signal according to a data-enable signal; an encode unit (15) which encodes the plurality of packet signals so as to generate a plurality of encode packet signals; and a serializer (14) which parallel-serial-converts the encode packet signals so as to generate serial packet signals. The packer (11) generates a control signal containing a pulse of the pulse width corresponding to the number of bytes of the packet. The encode unit (15) subjects a portion of packet signals corresponding to the pulse in the control signal from the packer, to an encode process different from a process for the other portion.
