Appl. No.:

13/333135

Inventors:

Brian Heng - Irvine CA, US
Wade K. Wan - Orange CA, US
Zhijie Yang - Irvine CA, US

Assignee:

BROADCOM CORPORATION - IRVINE CA

International Classification:

H04N 7/26

US Classification:

37524001, 375E07198

Abstract:

Multi-mode error concealment, recovery and resilience coding. Adaptation of a number of coding units (CUs) employed in accordance with video coding may be made as a function of error. As a number of errors increases, the respective number of CUs may correspondingly increase (e.g., which may be made in accompaniment with a reduction of CU size). As a number of errors decreases, the respective number of CUs may correspondingly decrease (e.g., which may be made in accompaniment with an increase of CU size). Such errors may be associated with a type of source providing a video signal, a type of error resilience coding employed, communication link and/or channel conditions, a remote error characteristic (e.g., such as associated with a source device and/or destination device), a local error characteristic (e.g., such as associated with operations and/or processing within a given device), and/or any other type of consideration.

Abstract:

Video coding tree sub-block splitting. A parser and treeblock splitter is implemented for adaptive partitioning of treeblocks (TBs) into various respective sub-treeblocks (STBs). Such adaptation may be tailored for effectuating parallel processing in accordance with video decoding. Different respective decoding engines may each individually and respectively also perform further partitioning of the STBs into sub-STBs as well. Such adaptation of respective STB size and/or sub-STB size may be made based on local and/or remote consideration(s). For example, adaptation may be made based upon communication link and/or channel conditions, a remote characteristic (e.g., associated with a source device and/or destination device), a local characteristic (e.g., associated with operations and/or processing performed locally within a given device), and/or any other type of consideration. Different respective portions of a video signal may be processed using different respective sized STBs/sub-STBs (and different respective engines may also employ different respective sized STBs/sub-STBs).

International Classification:

H04N 7/26

US Classification:

37524002, 375E07126

Abstract:

Advance encode processing based on raw video data. Adaptive processing of a video signal may be made by making one or more decisions and/or directing one or more encoding steps based upon characteristic(s) associated with the video signal in raw form (e.g., before the video signal undergoing any processing in accordance with generating an output video bitstream). Characteristic(s) associated with the video signal (raw form) may be used to drive intra-prediction angular mode selection, including making a preliminary/coarse angular mode selection (e.g., which may be refined and/or modified based upon partial and/or full processing of the video signal). Characteristic(s) associated with the video signal (raw form) may be used to drive intra-prediction/inter-prediction operational mode selection (or intra-prediction/inter-prediction/neither operational mode selection). An integrated and/or embedded video decoder within a video encoding device may be provisioned to assist in adaptation of one or more of the video encoding operations.

US Classification:

37524002, 375E07126, 375E07127

Abstract:

Video coding infrastructure using adaptive prediction complexity reduction. One or more subsets associated with one or more frames or pictures of the video signal may be adaptively selected and used for motion vector calculation (e.g., such as in accordance with inter-prediction). For example, a picture or frame of the video signal may be partitioned into a number of respective regions. Any one or more, but typically fewer than all, of the respective regions may be appropriately selected, and stored, based on any one or more considerations for use in motion vector calculation (e.g., inter-prediction). A sub-sampled or down-sampled picture or frame [or alternatively, a sub-sampled or down-sampled version of one or more respective regions of a picture or frame] (e.g., the sub-sampling or down-sampling ratio which may be adaptively determined based on any one or more considerations) may be stored for use in motion vector calculation (e.g., inter-prediction).

US Classification:

37524002, 375E07126

Abstract:

Video coding sub-block sizing based on infrastructure capabilities and current conditions. Sub-block size, such as employed in accordance with the video processing, maybe adaptively modified based on any of a number of considerations. For example, such adaptation of sub-block size may be made with respect to one or more characteristics associated with streaming media source flow(s) and/or streaming media delivery flow(s) being received by and/or output from a given device including a video processor. For example, such a video processor may be a video decoder implemented within a middling or destination device. Such a video processor may be a video encoder implemented within the middling or source device. Adaptation of sub-block size employed in accordance with video coding may also be effectuated in accordance with feedback or control signaling provided between respective devices. (e.g., from destination or source device to middling device, or from destination device to source device, etc.).

Abstract:

A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be separate frames. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a single frame. The first half-resolution view in the SVC base layer may be a base-layer reference for the first high-resolution view in the SVC enhancement layer for inter-layer prediction of spatial scalable coding. The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.

Abstract:

The present disclosure describes a video communication environment for encoding and/or decoding video frames in accordance with various video coding formats utilizing various coding parameters. The video communication environment can include one or more encoding verification circuit and/or decoding verification circuit throughout which utilizes the various coding parameters to model dynamics of decoding various encoded video frames and/or display timing for displaying various decoded video frames. This modeling of the dynamics of decoding and/or display timing can be used to verify whether these various encoded video frames, once decoded, can be displayed smoothly, for example, without jitter. In some situations, the modeling of the dynamics of decoding and/or display timing can be used to guide decoding and/or display process to display the various decoded video frames smoothly.

Abstract:

A system may receive an input stream for a coding operation by a coding device. The system may determine a processing device to assist the coding device with the coding operation. The processing device may generate an indicator containing coding information or other coding assistance by processing the input stream. The processing device may send the indicator to the coding device. In some cases, the indicator may be embedded in the metadata of the stream by the processing device. The indicator may be extracted by the coding device. After reception of the indicator, the coding device may execute the coding task while using the information in the indicator to assist.
