Abstract
A method and system are provided for using generic comparators with firmware interface to assist video/audio decoders in achieving frame sync. The method may involve processing a portion of an incoming packet by hardware components, which may result in a partially processed packet. The incoming packet may comprise audio, video, and/or record data. The partially processed packet may then be completely processed by firmware and sent to decoders if comprising audio/video data or to a record engine if comprising record data. Generic comparators may be utilized with the incoming packet to search for data patterns associated with synchronization information within the packet. The extracted data patterns may be sent to the firmware to utilize while processing the partially processed packet. The firmware may send synchronization information determined based on the extracted data patterns to aid decoders in decoding audio and video content.
