Abstract
A video transmission device 10 has: a packer 11 which receives a video signal, a sync signal, and a data-enable signal, and generates a plurality of packet signals by packetizing the video signal and the sync signal based on the data-enable signal and according to the number of bytes of a packet corresponding to the number of gradation bits of the video signal; an encode unit 15 which generates a plurality of encoded packet signals by encoding the plurality of packet signals; and a serializer 14 which generates a serial packet signal by parallel-serial converting the plurality of encoded packet signals. The packer 11 generates a control signal including a pulse with a pulse width corresponding to the number of bytes of the packet, and the encode unit 15 subjects a portion of the packet signals corresponding to the pulse in the control signal from the packer, to an encode process which is different from a process for the other portion.
