Patent ID: 8311093

Claim:
A signal transmitting apparatus comprising: a mapping unit that is configured, in response to transmitting an input image signal where a number of pixels in one frame exceeds a number of pixels defined by high-definition serial digital interface (HD-SDI) format and an audio signal inputted in synchronization with the input image signal, to divide each frame in the input image signal into first, second, third, and fourth subimages and map respective pixel samples of the first, second, third and fourth subimages onto image data regions of two-channel HD-SDI signals, respectively, and to map the audio signal onto supplementary data regions included in horizontal ancillary data spaces of any of the two-channel HD-SDI signals onto which the respective pixel samples of the first, second, third, and fourth subimages are mapped, respectively; a multiplexing unit that multiplexes the pixel samples mapped onto the image data regions of the two-channel HD-SDI signals onto an image data region of a first transfer data stream and the audio signal mapped onto the supplemental data regions included in horizontal ancillary data spaces of any of the two-channel HD-SDI signals onto a horizontal ancillary data space of a second transfer data stream; and an output unit that outputs the first and second transfer data streams sent from the multiplexing unit.
