Abstract
Efficient error protection strategies for robust satellite broadcast of high-definition television (HDTV) and conventional TV are investigated. The concatenated Reed-Solomon/convolutional code is preferred over the RS code for fewer adverse effects on variable-length codes. A decoded bit error rate of 10/sup -10/ or below can be achieved for all transmitted information at a low threshold E/sub b//N/sub 0/. The most critical video packet data are received near-error-free by using an additional layer of block coding with minimal redundancy and complexity. The effect of loss of synchronization for variable-length codewords due to channel errors is minimized by simple error detection and concealment methods. Digital transmission architectures for the satellite broadcast of HDTV and conventional TV are outlined.<>Keywords
