Abstract:
Methods and systems for receiving, processing and/or decoding digital video signal and acquisition of transmission parameters encoded therein. The method generally includes providing an initial set of parameters for decoding the digital video signal, finding a synchronization block position by matching bits of the transmission parameter signal to a predetermined pattern, obtaining raw transmission parameter bits from the transmission parameter signal based on the synchronization block position, storing the raw transmission parameter bits, and updating at least one of the initial set of parameters with at least one updated transmission parameter value from the raw transmission parameter bits. Embodiments of present invention advantageously provide a faster approach for synchronizing with the frame boundaries of transmission parameter blocks to decode digital video signals.
