Abstract: Systems and methods for streaming content are disclosed. A Media Presentation Description (MPD) may be associated with streaming content, for example, in Dynamic Adaptive Streaming Over HTTP (DASH). An MPD may comprise an element, e.g., a header element or URL query element, which provides a name/Value functionality. An element may allow a request that results in insertion of custom headers. Requests may be used for retrieval of a subsegment, segment, or MPD, re-referencing of remote elements, or triggered by an event. The event may be embedded either in an MPD or in segments.

Abstract: Systems and methods are described for encoding and decoding video using derived block vectors as predictors in intra block copy mode. In an exemplary encoding method, an encoder identifies at least a first candidate block vector for the prediction of an input video block, where the first candidate block vector points to a first candidate block. The encoder then identifies a first predictive vector (e.g. a block vector or a motion vector) that was used to encode the first candidate block. From the first candidate block vector and the first predictive vector, the encoder generates a derived predictive vector from the first candidate block vector and the first predictive vector. The encoder then encodes the video block in the bit stream using the derived predictive vector for the prediction of the input video block.

Abstract: A video coding device may encode a video signal using intra-block copy prediction. A first picture prediction unit of a first picture may be identified. A second picture may be coded and identified. The second picture may be temporally related to the first picture, and the second picture may include second picture prediction units. A second picture prediction unit that is collocated with the first picture prediction unit may be identified. Prediction information for the first picture prediction unit may be generated. The prediction information may be based on a block vector of the second picture prediction unit that is collocated with the first picture prediction unit.

Abstract: A video coding device may receive a video bit-stream that carries a video captured in a non-4:4:4 chroma format. A palette mode may be used to decode the video bit-stream. The video bit-stream may include data defining a palette table and a palette index map in a 4:4:4 chroma format for the current block. A luma sample value for a luma sample position in the non-4:4:4 chroma format may be determined based on the luma sample position, the palette index map and the palette table. A chroma sample position associated with the 4:4:4 chroma format on the palette index map may be derived based on the luma component to chroma component resolution ratio in the non-4:4:4 chroma format. A chroma sample value for a chroma sample position in non-444 chroma format may be determined based on the derived chroma sample position, the palette index map and the palette table.

Abstract: Embodiments contemplate devices and techniques for receiving unicast and multicast transmissions over a downlink (DL) shared channel in parallel, for example an LTE DL shared channel (SCH). For example, one or more hybrid automatic repeat request (HARQ) entities may be configured to perform retransmissions of the multicast and/or unicast messages. Common and/or dedicated (e.g., separate) HARQ entities may be utilized for retransmission. The multicast downlink shared channels may be activated and/or deactivated on demand. The activation and/or deactivation may be performed using radio resource control (RRC) signaling and/or Medium Access Control (MAC) signaling. The multicast and/or unicast downlink shared channel data may include scalable video coding (SVC) data of varying priority. Embodiments also contemplate the use of simultaneous (e.g. parallel) multicast/unicast for scalable video coding transmission over WiFi/802.11 protocol signals.

Abstract: An palette index map of a video coding unit may be flipped during palette coding if a large run of similar pixels are present at the beginning of the coding unit and a small run of similar pixels are present at the end of the coding unit. The flipping may enable efficient signaling and coding of the large run of pixels. An indication may be sent signaling the flipping. During decoding, an inverse flip may be performed to restore the pixels of the flipped coding unit to their original positions. Selection of a prediction mode for palette coding may take into account various combinations of an index mode run followed by a copy-above mode run. A prediction mode with die smallest per-pixel average bit cost may be selected. Palette sharing may be enabled.

Abstract: Systems and methods are provided for adapting communication parameters to a variety of link conditions, traffic types and priorities. For example, WiFi transmission parameters (e.g. retry limit, AIFS, CW size, MCS order and/or CCA threshold) may be adapted to channel congestion levels, channel errors and/or traffic priority levels. Parameter adaptation may be coordinated across layers (e.g. between MAC and PHY layer parameters). Congestion levels may be detected, for example, using a smoothed queue size and/or channel busy time. Traffic may be transmitted using adapted parameters, such as reduced retry limits for a high congestion level and increased retry limits for priority traffic in response to channel error. Feedback may support parameter adaptation. For example, feedback may be provided by a receiver and/or within a sender, such as a sender MAC and/or PHY layer or a parameter adapter providing feedback (e.g. spoofed NACK packet) to a sender application, transport and/or network layer.

Abstract: Embodiments disclosed herein operate to improve prior video coding techniques by incorporating an IntraBC flag explicitly at the prediction unit level in merge mode. This flag allows separate selection of block vector (BV) candidates and motion vector (MV) candidates. Specifically, explicit signaling of an IntraBC flag provides information on whether a specific prediction unit will use a BV or an MV. If the IntraBC flag is set, the candidate list is constructed using only spatial and temporal neighboring BVs. If the IntraBC flag is not set, the candidate list is constructed using only spatial and temporal neighboring MVs. An index is then coded which points into the list of candidate BVs or MVs. Further embodiments disclosed herein describe the use of BV-MV bi-prediction in a unified IntraBC and inter framework.

Abstract: Methods and apparatus are provided for performing one-dimensional (1D) transform and coefficient scanning. An encoder may apply 1D transform in either a horizontal or a vertical direction. The encoder may then determine a coefficient scan order based on the 1D transform direction. The scan order may be determined to be in a direction orthogonal to the 1D transform direction. The encoder may further flip the coefficients prior to scanning. The flipping may also be in a direction orthogonal to the 1D transform direction. A decoder may receive indications from the encoder with respect to the 1D transform, coefficient scanning, and/or coefficient flipping. The decoder may perform functions inverse to those performed by the encoder based on the indications.
