Adapting communication parameters to link conditions, traffic types, and/or priorities

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... Vid Scale Inc

Intra block copy coding with temporal block vector prediction

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... Vid Scale Inc

One-dimensional transform modes and coefficient scan order

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... Vid Scale Inc

Systems and methods for spatial prediction

Systems, methods, and instrumentalities are disclosed relating to intra prediction of a video signal based on mode-dependent subsampling. A block of coefficients associated with a first sub block of a video block, one or more blocks of coefficients associated with one or more remaining sub blocks of the video block,... Vid Scale Inc

High level syntax for hevc extensions
