Abstract: Techniques related to parallel block video coding using an adaptive wavefront split are discussed. Such techniques include adaptively applying a wavefront split in a video frame based on a frame level quantization parameter of the video frame, an encode duration of a previous frame, and/or image content of the video frame.

Abstract: Techniques related to reduction of artifacts in parallel block coding mode selection for video are discussed. Such techniques include, for blocks along a parallel processing split boundary of a video frame, coding mode selection that divides a block into sub-blocks, performs motion estimation for the sub-blocks with skip check disabled and using distortion and coefficient coding cost but exclusive of motion vector coding cost, and evaluates a skip check for the block using the sub-block motion vectors.

Abstract: A method for controlling admissions of data packets across a packet network comprising the steps of establishing a communication route along a plurality of interconnected secondary nodes, determining an amount of available network and determining whether to admit the data packets to the communication route based on the determined amount of available network bandwidth. Also disclosed is a system for implementing the method comprising a first provider edge element, a second provider edge element, a plurality of interconnected secondary nodes disposed between the edge elements. Each of the secondary nodes comprises at least one first detection device for determining an amount of available network bandwidth and at least one admission device in communication with the respective first detection device for determining whether to admit the data packets to the communication route based on the determined amount of available network bandwidth.
