    摘要: Methods and apparatuses to encode multimedia data enabling, among others, for example, improved decoded video quality, improved error recovery capabilities and/or improved decoding efficiency are described. An encoder device determines one or more distortion values for one or more portions of multimedia data based at least in part on one or more concealment methods related to concealing the one or more portions if the one or more portions were received in error. The encoder device determines one or more encoding methods for the one or more portions based at least in part on the one or more estimated distortion values. In one aspect, determining the one or more encoding methods comprises determining the one or more encoding methods so as to refresh the one or more portions based at least in part on a comparison of the one or more estimated distortion values and one or more thresholds.

    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: An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve compression efficiency and reconstructed video quality is disclosed. One operation of the EA-FRUC system involves determining whether to encode a frame in a sequence of frames of a video content by determining a spatial activity in a frame of the sequence of frames; determining a temporal activity in the frame; determining a spatio-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining a level of a redundancy in the source frame based on at least one of the determined spatial activity, the determined temporal activity, and the determined spatio-temporal activity; and, encoding the non-redundant information in the frame if the determined redundancy is within predetermined thresholds.

    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.
