The latest High Efficiency Video Coding (HEVC) standard achieves significant compression efficiency improvement over the H.264 standard, at a much higher cost of computational complexity. A framework for software-based H.264 to HEVC transcoding on multicore processors and distributed systems is provided. By utilizing information extracted from the input H.264 bitstream, the transcoding process can be accelerated at a high ratio with modest visual quality loss. Wavefront Parallel Processing (WPP) and SIMD acceleration are also implemented to improve the trans coding efficiency on multi-core processors with SIMD instruction set extensions. Based on the HEVC HM 12.0 reference software and using standard HEVC test bitstreams, the proposed transcoder can achieve around 120&#xd7; speed up over decoding and re-encoding based on ffmpeg and the HM software without significant R-D performance loss.

The emerging High Efficiency Video Coding (HEVC) standard achieves significant performance improvement over H.264/AVC standard at a cost of much higher complexity. An H.264/AVC to HEVC transcoder is described for multi-core processors implementing Wavefront Parallel Processing (WPP) and SIMD acceleration, along with expedited motion estimation (ME) and mode decision (MD) by utilizing information extracted from the input H.264/AVC stream. Experiments using standard HEVC test bitstreams show that the described transcoder may achieve a 70&#xd7; speed up over the HEVC HM S.1 reference software (including H.264 encoding) at very small rate distortion (RD) performance loss.

A congestion control mechanism for TCP communication sessions is described. The congestion control mechanism adjusts the size of the congestion window based on a number of parallel virtual TCP Hybla connections. The number of parallel virtual TCP Hybla connections used to determine the congestion window can be dynamically adjusted. The enhanced TCP Hybla congestion control mechanism provides improved throughput for heterogenous networks having a high latency link and having possible packet loss.

An audio/video device may determine that a UI is displayed in a first AV signal, and may capture a frame of the UI in order to provide UI information to a UI generation component that generates a second UI. The AV device may then provide the second UI for display in place of the first UI. The AV device may act as a virtual controller device capable of controlling multiple devices and streaming content from multiple devices to multiple displays.

In some embodiments, a video decoder is capable of recovering skipped video data (e.g. motion vectors, prediction modes, quantization parameters, selected frequency-domain coefficients such as DC and 5-lowest-frequency AC coefficients, and/or entire video data blocks) using multiple alternative recovery modes such as spatial interpolation, temporal interpolation, and motion search. To decide whether to skip a particular data type for a block, the encoder evaluates the effect of skipping the data on rate and distortion by simulating the decoder data recovery using the multiple recovery modes. The encoder transmits indicators of skipped data types and associated recovery modes, if different from decoder baselines. The skipped data and recovery mode indicators may be included in macroblock and/or slice headers, and/or as part of sequence, group-of-picture (GOP), or picture coding parameter data. Skipped data recovery decoder resources (e.g. motion search logic) may be used for recovering data lost due to transmission errors.
