Abstract: A device implementing the subject video coding system may include a processor that encodes an N×M block using an x-tap filter for horizontal interpolation and a y-tap filter for vertical interpolation, where x is proportional to N and y is proportional to M. The processor may use a current block size to select an interpolation filter with a first length or a second length for a current block, use an overlapped block size to select an interpolation filter with a first length or a second length for overlapped areas, and, when a neighboring block uses a long interpolation filter and a short interpolation filter is selected for the overlapped area, maps the long interpolation filter to a short interpolation filter of a selected type. The processor may calculate a reference block size based on a scaling factor and use the reference block size to select a filter length.

Abstract: The invention provides methods of digital amplification using primers of limited nucleotide composition. Limited nucleotide composition means that the primers are underrepresented in at least one nucleotide type.

Abstract: A method, system, and computer program product for adaptive decoding is provided herein. The method includes the steps of receiving a video bitstream, selecting an initial extraction level, and switching to a lower quality extraction level if a decoding rate is less than a rate at which data extracted from the video bitstream is sent to the decoder. The method further includes the step of switching to a higher quality extraction level if the decoding rate is greater than a rate at which data extracted from the video bitstream is to the decoder.

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.

Abstract: The invention provides methods of amplification from a single primer or a pair of forward and reverse primers of limited nucleotide composition. Limited nucleotide composition means that the primers are underrepresented in at least one nucleotide type. Such primers have much reduced capacity to prime from each other or to extend initiated by mispriming from other than at their intended primer binding sites in a target nucleic acid.

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.

The selection logic may send an indication of the selected coding mode and coding strategy to coding logic to support execution of the coding operation, which may use the selected coding mode and coding strategy.

Abstract: Within a device, 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 of that picture or frame 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).

Abstract: In various embodiments, video streams are decoded using decoders that support a different decoding profile. First processing circuitry is configured to receive a video stream encoded using a first encoding profile, transcode the video stream from the first encoding profile to a second encoding profile, and store the transcoded video stream in an output buffer. Second processing circuitry is configured to receive the transcoded video stream from the output buffer and decode the transcoded video stream according to the second encoding profile. The second processing circuitry may be unable to decode the video stream encoded using the first encoding profile.

Abstract: In conventional packet communications systems, such as MPEG-2, the data stream includes a program clock reference (PCR) so that the receiver decoder can lock on to the data stream. The invention eliminates the need to send the PCR by transferring a data transport rate explicitly in the header of the data packets so that the decoder can use the transport rate as a locking reference and adjust its phase lock loop. The transport rate is carried in the adaptation field as user private data.

Abstract: Aspects of virtual field buffer based decoding are described. In one embodiment, a current picture field is read from a coded picture buffer comprising coded pictures of video, for example. The current picture may be associated with a top or bottom field polarity. According to decoding and picture output orders, the current picture field is assigned to an available field entry of a virtual field buffer, and an available frame index of a virtual frame map is assigned to the current picture field. The assignment of the available frame index to the current picture field is indicated to a decoder that decodes the current picture field with reference to the assigned frame index. According to aspects of the embodiments described herein, rather than determining complimentary picture fields after decoding, the assignment of complimentary picture fields to virtual frame indexes before decoding provides certain efficiencies.

Abstract: Disclosed are various embodiments for determining a filter length according to a width and height of the reference block and selecting a filter based on the block size.

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.).
