Video signal transmission device, video signal reception device and video signal transferring system

A video signal transmission device, comprising:

• a packer unit configured to capture a data enable signal and a video signal constituted by one or more pixel signals, each of which corresponds to one pixel and includes a color signal and a sync signal, and apply packetizing processing to the video signal in accordance with the data enable signal so that the video signal has a packet configuration of size corresponding to the number of pixels per video signal and the number of tone bits of the color signal to generate a plurality of block signals;
• an encoder unit configured to apply encoding processing to the plurality of block signals to generate a plurality of encoded block signals;
• and
• a serializer configured to apply parallel-serial conversion to the plurality of encoded block signals to generate a serial signal, wherein
• the packer unit generates a control signal including a pulse having a pulse width corresponding to the number of tone bits of the color signal, and each of block signals generated in a first period of the control signal, in which a pulse exists, among the plurality of block signals includes information on the number of pixels, and
• the encoder unit applies encoding processing of encoding efficiencies different between the first period of the control signal and a second period of the control signal distinguished from the first period depending on existence or non-existence of the pulse.
