Techniques described herein are directed toward creating one or more 'dynamic profiles' for media (video) streaming in which an encoding bit rate (and optionally other profile settings) is optimized for particular content. More specifically, techniques involve performing one or more “probe” encodings of the particular content to determine an encoding bit rate (and optionally other profile settings) that results in an encoding having a quality value sufficiently near (within a threshold) a target quality value.

Optimization of encoding profiles for media streaming

Techniques are disclosed for the creation of multi-codec encoding profiles (or encoding ladders), which define quality and bitrate for each of the streams made available to clients for streaming a video. In particular, optimization techniques may take into account a quality rate function of each of the codecs when determining the encoding ladder. Additional considerations may include a network bandwidth distribution and/or a distribution of client types.

Optimal multi-codec ABR ladder design

Techniques described herein are directed toward creating one or more 'dynamic profiles' for media (video) streaming in which an encoding bit rate (and optionally other profile settings) is optimized for particular content. More specifically, techniques involve performing one or more 'probe' encodings of the particular content to determine an encoding bit rate (and optionally other profile settings) that results in an encoding having a quality value sufficiently near (within a threshold) a target quality value.

Transform coefficients of sample blocks of a macroblock of a video picture are encoded by adaptively encoding a combination, the number of non-zero coefficients before the trailing one coefficients and the number of trailing one coefficients. The transform coefficients may be further encoded by adaptively encoding one or more of the signs of the trailing one coefficients, the level measures of the interposed in the non-zero coefficients. Adaptive encoding of the number and trailing one coefficients may be performed in view of one or more neighboring sample blocks, whereas adaptive encoding of level measure may be performed in view of quantization parameters of a macroblock and previously encoded level measures. Decoding may be performed in an inverse manner.

Context-adaptive VLC video transform coefficients encoding/decoding methods and apparatuses

A video receiver/renderer is provided with a decoder equipped with hardware and/or software components adapted to decode at least two slices of a video in parallel, in part. In various embodiments, the decoder is constituted with multiple decoding units or decoding instructions that can be executed in multiple threads. A decoding unit/thread is advantageously equipped to determine whether a slice has decoding dependency, if so, whether the portion(s) of the video on which a slice's decoding is dependent has/have been decoded. If the result of the latter determination is negative, the decoding unit suspends itself until the determination result is affirmative. If the slice has no decoding dependency or the determination result is affirmative, the decoding unit proceeds to decode the slice.

Parallel video decoding

A video compression and decompression system has an input to receive an encoded video sequence and an output for a decoded video sequence. A video decoder is coupled to the input and decode the received encoded video sequence. A filter module is coupled to the video decoder and the output and filters the decoded video sequence from the video decoder. The filter module has a variable filter strength that is a function of detected motion activity within the video sequence. The filter module filters coding artifacts, such as mosquito artifacts and blocking artifacts from the decoded video sequence so that the displayed video is more pleasing for a viewer's eyes.

Video compression and decompression system with postfilter to filter coding artifacts

A method for removing noise from a video input, prior to encoding includes receiving a frame of a video signal, identifying noise within the frame, and eliminating the noise from the frame. The video frame may then be encoded.

Noisy edge removal for video transmission

A program is executed on a first computer. In response to an error being detected in the execution of the program, the computer automatically retrieves revision code stored on another computer to revise the program.

Initiating corrective action after the occurrence of a program error

A feedback mechanism for adaptively enabling and disabling an advanced prediction mode for video data processing is disclosed. A quantization parameter (QP) threshold is set and a QP mean for an error frame is determined. The advanced prediction mode is enabled if the QP mean is less than the QP threshold.

Method and apparatus for adaptively switching on and off advanced

A method and apparatus for adaptively enabling a PB frames mode for video data processing. If the PB frames mode is enabled for a given pair of video pictures, and if the motion compensated prediction error for the B-picture in the most recently encoded PB frame is greater than the motion compensated prediction error for the P-picture in same PB frame multiplied by a constant, the PB frames mode is disabled for the PB frame. Otherwise, the PB frames mode remains enabled. If the PB frame is disabled by the PB decision logic, it may remain disabled until certain encoding parameters are met.
