    摘要： Methods and apparatus for service acquisition. In an aspect, a method is provided for service acquisition. The method includes generating one or more channel switch video (CSV) signals associated with one or more multimedia signals, encoding the CSV signals and the multimedia signals to produce error coded blocks, and encapsulating the error coded blocks into a multiplex signal. In an aspect, an apparatus is provided for service acquisition. The apparatus includes a source encoder configured to generate one or more channel switch video (CSV) signals associated with one or more multimedia signals, an error encoder configured to encode the CSV signals and the multimedia signals to produce error coded blocks, and a packer configured to encapsulate the error coded blocks into a multiplex signal.

    摘要： This disclosure describes techniques for adjusting encoding variables of an encoding device. In response to a request to resize a segment of data, an encoding module adjusts at least one encoding variable used to encode one or more subsequent segments of data such that the subsequent segments of data are encoded at a bit rate that is different than the bit rate at which the subsequent segments of data would have been encoded had there been no request to resize. At some point, the encoding module re-adjusts the encoding variables used to encode the segments of data such that the subsequent segments of data are encoded to achieve a desired encoding result. For example, the encoding module may re-adjust the encoding variables after a period of time or may incrementally adjust the encoding variables until the encoding variables result in achieving the desired encoding result.
