Optimization of synchronization control in concatenated decoders |
摘要 |
A concatenated three layer Viterbi, Reed-Solomon/Deinterleaver and Descrambler forward error correction decoder may be utilized in digital video and audio systems, and for direct broadcast satellite applications. The digital signal may be a compressed video and audio signal transmitted from a direct broadcast satellite. Acquisition for three layers of synchronization are required, but once all three layers are in-sync, down stream data synchronization monitoring will suffice so that upstream synchronization monitoring can be disabled thus improving system robustness to noise bursts and false synchronization on false sync bytes generated at the transmission encoder during non-changing data signal conditions.
