    摘要： A multiple bitrate (MBR) video encoding management tool utilizes available processing units for parallel MBR video encoding. For example, instead of focusing only on multi-threading of encoding tasks for a single picture or group of pictures (GOP), the management tool parallelizes the encoding of multiple GOPs between different processing units and/or different computing systems. With this parallel MBR video encoding architecture, different GOPs can be encoded in parallel. To facilitate such parallel encoding, data dependencies between GOPs are removed. The management tool can adjust the number of GOPs to encode in parallel on a computing system so as to favor parallelism of encoding for different GOPs at the expense of parallelism of encoding inside a GOP, or vice versa, and thereby set a suitable balance between encoding latency and throughput.

    摘要： A decoder which can detect errors in MPEG-2 coefficient blocks can identify syntactically-correct blocks which have out-of-bounds coefficients. The decoder computes coefficient bounds based on quantization scalers and quantization matrices and compares these to coefficient blocks during decoding; if a block has out-of-bounds coefficients, concealment is performed on the block. In a decoder implemented all in software, coefficient bounds checking is performed on iDCT coefficients against upper and lower bounds in a spatial domain. In a decoder which performs iDCT in hardware, DCT coefficients are compared to an upper energy bound.

    摘要： Access to one or more data streams can be controlled by encrypting a description of how segments of the data streams can be assembled, for example, to produce an audio or video program. Access to the one or more data streams can also be provided by obfuscating names of at least some of the segments in order to make it more difficult to determine the proper order for assembling the segments. In at least some embodiments, the data contained in at least some of the segments themselves is not encrypted.

    摘要： Reference pictures can be created to assist with video decoding. For example, a method for decoding video can comprise receiving an encoded video bit stream, determining that a reference picture is needed, and creating and inserting the reference picture into the encoded video bit stream. A method for decoding video can also comprise receiving an encoded video bit stream, performing bit stream parsing, determining that a reference picture is needed, selecting a representation level for the reference picture, and conveying data for the selected reference picture to a hardware accelerated graphics processing unit. Various video operations, such as creating reference pictures and related information, can be performed by central processing units, while other video decoding operations can be performed by graphics processing units.

    摘要： The present disclosure relates to playback of video/audio streaming media data to provide a substantially glitch-free experience. The system adapts the media stream to the user connection in order to choose the most desirable stream to avoid glitches. For example, in the case where there is interference (e.g., a microwave being used near a wireless device), the quality of the media stream is lowered. In one embodiment, an index file is used to make logical decisions about which media stream to choose in order to minimize glitches. The index file can take different forms, but, generally, includes characteristics about the available media streams. Example characteristics include the bit rates of the media streams and quality information about the media streams.
