Methods and device for fast acquisition of digital video signals

摘要

Methods and systems for receiving, processing and/or decoding digital video transmissions are disclosed. In one embodiment, a method of a method of processing a digital video signal includes the steps of applying an initial set of video transmission parameter values to one or more digital video signal processes, decoding video transmission parameter information from the digital video signal, and updating the initial set of video transmission parameter values with the decoded video transmission parameter information. Embodiments of the present invention can advantageously demodulate and decode a digital video signal before transmission parameters embedded in the signal are completely decoded. Thus, the time to acquire and/or scan a digital video channel is improved.
