Patent ID: 8407566

Claim:
An Unequal Error Protection (UEP) transmission apparatus, comprising: a channel coding unit configured to create channel-encoded Most Significant Bit (MSB) data and channel-encoded Least Significant Bit (LSB) data by performing error correction encodings respectively corresponding to an MSB Medium Access Control (MAC) sub-frame and an LSB MAC sub-frame, the MSB MAC sub-frame and the LSB MAC sub-frame being separately created based on a degree of importance on a pixel-component basis of video data; and a symbol mapping and modulation unit configured to perform modulations by mapping the channel-encoded MSB data and the channel-encoded LSB data to a predetermined number of symbols based on the degree of importance, wherein the symbol mapping and modulation unit is configured to enable the channel-encoded MSB data to have a greater Euclidean distance than the channel-encoded LSB data.
