Abstract
An Unequal Error Protection (UEP) transmission apparatus comprises a bit separator unit configured to, when video data are received, separate pixels of the video data into Most Significant Bits (MSBs) and Least Significant Bits (LSBs) according to a degree of importance on a pixel-component basis; a header generation unit configured to create an MSB sub-frame and a LSB sub-frame based on the respective MSBs and LSBs and create an MSB Medium Access Control (MAC) sub-frame and a LSB MAC sub-frame to which respective headers are added; and a channel coding unit configured to create a channel-encoded MSB data and a channel-encoded LSB data by performing error correction encodings corresponding to the respective MSB MAC sub-frame and LSB MAC sub-frame and add padding bits, corresponding to the respective channel-encoded MSB data and channel-encoded LSB data, to the channel-encoded MSB data and channel-encoded LSB data.
