Abstract:
1. A signal transmitting device that transmits, during a broadcast, an input image signal in which a number of pixels of one frame is larger than the number of pixels specified in a HD format, comprising: a mapping unit that extracts a plurality of samples from each frame of the input image signal in units of two adjoining pixels, fetches the samples in equal order frame by frame, maps the samples into active periods of first, second, third, and fourth sub-images conformable to the HD format, separates each of the mapped first, second, third, and fourth sub-images into a first-link transmission channel and a second-link transmission channel, and therein maps the sub-images into eight channels; a parallel-to-serial conversion unit that serially converts the mapped first, second, third, and fourth sub-images; and an output unit that outputs, during the broadcast, serial digital data which is serially converted by the parallel-to-serial conversion unit.
