Abstract: Sample adaptive offset (SAO) in accordance with video coding. SAO filtering may be performed before de-blocking processing (e.g., in accordance with video signal decoding and/or encoding). For example, a receiver and/or decoder communication device may receive signaling from a transmitter and/or encoder communication device that includes various band offsets. Corresponding band indices may be determined via analysis of the received video signal (e.g., received from the transmitter and/or encoder communication device), inferentially without requiring signaling of such band indices from the transmitter and/or encoder communication device. Upon appropriate analysis of one or more largest coding units (LCUs) generated from the video signal to determine a pixel value distribution (e.g., which may be using a histogram in one instance), then based on that pixel value distribution, the band indices are identified and the band offsets applied thereto.

Abstract: Adaptive loop filter (ALF) padding in accordance with video coding. Various types of video processing are performed including performing virtual padding. When a filter coefficients collocated pixel is not available, that pixel may be replaced using an available pixel within a given location within a filter to process a number of pixels. For example, an available pixel located within the center of such a filter (e.g., which may be a cross shaped filter including a predetermined number of pixels, such as 18 pixels in one instance) may be used to replace those pixel locations which are not available in accordance with such virtual padding. With respect to the implementation of such an adaptive loop filter (ALF), such an ALF may be implemented to process a signal output from a de-blocking filter, from a sample adaptive offset (SAO) filter, and/or from a combined de-blocking/SAO filter in various implementations.

Abstract: Systems and methods are disclosed for video coding using signaling syntax and pixel predictions. The signaling syntax used for encoding and decoding video data is organized into multiple syntax groups based at least in part on the syntax type. The video data is coded plane by plane. The video data in each plane is coded in an order such that processing inter-prediction is prior to intra-prediction.

Abstract: Frequency domain sample adaptive offset (SAO). Video processing of a first signal operates to generate a second video signal such that at least one characteristic of a first portion of video information of the first video signal is replicated in generating a second portion of video information, such that the first portion of video information and the second portion of video information undergo combination to generate the second video signal. Such use of the first video signal may involve replication and scaling of the first video information to generate the second portion of video information. One possible characteristic of the first portion of video information may correspond to an energy profile as a function of frequency. One or more portions of the first video signal may be employed to generate different respective portions of the second signal. Such video processing operations may be performed on a block by block basis.

Abstract: Layered and scalable coding scheme is applied to one or more communication pathways between a transmitter and one or more receivers. Forward error/erasure correction (FEC) is applied for application layer erasure recovery. Additional FEC may also be employed at the physical layer (PHY) layer or channel coding layer for additional error correction capability and to provide joint application and PHY layer FEC coding. Source information (e.g., data, media such as image, video or audio, etc., or any other type of information) is encoded using two or more layers. These layers may include a base layer and one or more enhancement layers that, when combined with the base layer, modify the quality of the base layer. In a packet-based application, transmission of redundancy packets may be separately time-limited in the two or more layers. Also, adaptation (of signaling, FEC, etc.) may be made based on operating condition changes.

Abstract: An example video coding system may include a processor and memory. The processor may determine sets of parameters for slices that correspond to a picture of a video sequence, and determine, and store in overhead information, the set of parameters that has the highest commonality. The processor may determine for each slice whether the set of parameters determined for the slice is equivalent to the set of parameters stored in overhead information. If the set of parameters for the slice is equivalent to the set of parameters stored in overhead information, the processor may store an indication in a slice header of the slice that indicates that the set of parameters stored in overhead information applies to the slice, otherwise the processor may store in the slice header of the slice the determined set of parameters for the slice. The processor may transmit the overhead information and the slices.
