    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.

    摘要： This disclosure describes a number of techniques for processing multimedia data that can improve multi-program “picture-in-picture” viewing, particularly in a wireless mobile apparatus setting. In one example, a method includes receiving multiple channels of the multimedia data, decoding frames associated with two or more of the channels, presenting first frames of a first channel at a first frame rate, and presenting second frames of a second channel at a second frame rate while presenting the first frames, wherein the second frame rate is lower than the first frame rate. In another example, method includes receiving multiple channels of the multimedia data, receiving channel switch frames (CSFs) associated with the multiple channels, and simultaneously presenting the CSFs associated with two or more of the multiple channels to a user.

    摘要： This disclosure describes content-adaptive coding and modulation techniques. In particular, this disclosure describes techniques in which both a multimedia coding mode and a physical layer modulation scheme are adaptively selected based on content of a multimedia sequence. When the content changes such that either the coding or the modulation scheme can be improved, the coding and/or modulation may be changed to better optimize to the changed content. In one aspect, this disclosure provides a method of processing multimedia data, the method comprising selecting a multimedia coding mode for an encoder to encode the multimedia data and a physical layer modulation scheme for transmission of the multimedia data based on content of the multimedia data.
