Method and apparatus for unequal error protection of video signal over wideband high frequency wireless system
Abstract:
Disclosed are an Unequal Error Protection (UEP) method and apparatus of video signals based on a dynamic link in a broadband high frequency wireless system.A UEP transmission apparatus based on a dynamic link includes a UEP transmission controller to verify, based on a channel state when video data is inputted, a bit field size and a bit separation point of separating a priority for each pixel element being comprised of a pixel of the video data, and to control an error correction coding for correcting relatively many errors occurring in information with a high priority for each pixel element to be used, a bit separator unit to separate the video data pixel based on the priority for each pixel element, and a channel coding unit to perform a corresponding error correction coding through the control of the UEP transmission controller based on the priority for each pixel element.
