摘要： Disclosed are an Unequal Error Protection (UEP) apparatus and method thereof for transmitting various types of uncompressed video signals in a broadband high frequency wireless system. The UEP apparatus may include a UEP transmission controller to verify a bit separation point of separating a color depth and priority for each pixel element being composed of a video data pixel when video data is inputted, and to control an error correction coding of correcting relatively many errors to be used in information with a high priority for each pixel element, a bit separator to separate the video data pixel through a control of the UEP transmission controller based on the priority for each pixel element, and a channel coding unit to use a corresponding error correction coding through the control of the UEP transmission controller based on the priority for each pixel element.
