Codeword assignment for intra chroma mode signalling for HEVC
Intra prediction is used in state-of-the-art video coding standards such as AVC. The intra prediction modes are coded into the bitstream. Luma and chroma components could potentially have different prediction modes. For chroma components, there are 5 different modes defined in AVC: vertical, horizontal, DC, diagonal down right, and “same as luma”. Statistics show that the “same as luma” mode is frequent used, but in AVC, this mode is encoded using more bits than other modes during entropy coding, therefore the coding efficiency is decreased. Accordingly, a modified binarization/codeword assignment for chroma intra mode signaling is able to be utilized for high efficiency video coding (HEVC), the next generation video coding standard.
Method for improved intra prediction when reference samples are missing
The method for intra frame prediction allows for the recovery of some intra directional modes that are otherwise rendered useless due to the classical padding process. Directional modes are recovered by filling pixel locations in the prediction unit with samples from the portion of the unit that is determined to have samples available for use using a counterpart directional mode to the one that is useless. When it is determined that reference samples are missing for a particular prediction unit or portion thereof given a particular directional mode, a determination is made about whether reference samples along another portion of the prediction unit are available. The other portion is the side of the prediction unit at an opposite end of the particular directional mode. When it is determined that such reference samples are available, it is possible to extend the number of intra directional modes by replacing the particular directional modes that are rendered useless, because of the unavailability of reference samples, with their counterpart directional modes that are oppositely directed.

HEVC with complexity control based on dynamic CTU depth range adjustment
A High Efficiency Video Coding (HEVC) system that advantageously controls coding complexity at the coding tree unit (CTU) level. Complexity control is performed by adjusting a depth (or depth range) for CTUs in one or more video sequences in a video stream. To adjust CTU depth, complexity estimation and mapping is first performed to determine complexity requirements for one or more CTUs in a video frame or across frames. In doing so, a statistical complexity estimation model is utilized to yield significantly higher accuracy than other HEVC systems that operate under an assumption that each CTU consumes the same amount of encoding complexity. Complexity allocation is then utilized to ensure that each CTU is provided an optimum complexity. A probability-based CTU depth range adjustment process is utilized to select an appropriate depth range for each CTU.

A method and associated systems for on-demand bandwidth allocation on a mixed-infrastructure network in response to continuously changing populations of sensor devices. Sensors autonomously add themselves to or delete themselves from sensor clusters available to the network. A physical cluster controller detects each change, identifies resulting changes in a cluster's bandwidth requirements, and stores this information in a local database.

The component then distributes the adjusted bandwidth among its sensor-cluster controllers, which in turn allocate their adjusted bandwidths among their sensor devices.
