Abstract:
1. A method for decoding data streams comprising: receiving, at a receiver, a data stream in a first format from a transmitting device; decoding, using a first decoder of the receiver, a first block of data and a second block of data of the data stream using the first format, wherein the second block of data is predictively decoded using reference data generated using the first block of data, wherein the reference data is stored at a buffer of the first decoder; updating the reference data stored at the buffer of the first decoder based on the second block of data to generate updated reference data; receiving a control signal from the transmitting device indicating that the data stream is to be subsequently transmitted in a second format; in response to receiving the control signal, initializing a second decoder of the receiver using the updated reference data stored at the buffer of the first decoder, wherein the second decoder is configured to decode data streams using the second format, and wherein initializing the second decoder includes storing the updated reference data at a buffer of the second decoder; and subsequent to receiving the control signal, decoding a third block of the data stream using the second decoder, wherein the third block is predictively decoded using the updated reference data stored at the buffer of the second decoder, and wherein the second decoder decodes the third block of the data stream using the second format.
