摘要： A multiple video stream capture and encoding apparatus produces compressed data that represents multiple video streams capturing a common scene. Images from multiple video streams are analyzed to identify image color segments that are encoded into a composite graph data structure. Corresponding image segments across the multiple video streams are also identified and represented by one node in the composite graph data structure. The composite graph data structure also includes links between pairs of nodes that describe the relationship between the image segments associated with those nodes. The composite graph data structure is updated to represent changes to the image segments in the multiple video streams over time. The composite graph data structure is used to create compressed encoded data for storage and/or transmission.

摘要： Video coding includes one-stage coding a data block of video data using a first transform and two-stage coding the data block using a second direction-adaptive transform and the first transform. A first number of bits used to code the data block for the one-stage coding and a distortion are determined, and a second number of bits used to code the data block for the two-stage coding and a distortion are determined. The one-stage coding or the two-stage coding is selected to code the data block based on the distortion and the number of bits used to code the data block.

摘要： An adaptive resolution transcoding system and method adaptively transcodes a source video with an optimized resolution and visual quality based on the video coding complexity (VCC) of the source video. The transcoding system is configured to receive a source video in its native format, and to obtain the video coding complexity score of the source video from a video coding complexity engine. The transcoding system is further configured to set a resolution adjustment level based on the complexity score. Based on the resolution adjustment level, the transcoding system determines an optimal output resolution for the source video for each video output format supported by the transcoding system. Responsive to a user selection of video output format, the transcoding system determines an optimal output resolution for the source video and encodes the source video with the determined optimal output resolution.

摘要： A method of encrypting a transmission unit of a generalized scalable bit-stream includes, for each atom of the transmission unit, concatenating bit-stream segments that map to the atom to obtain data for each atom. The data for a logically first atom of the plurality of atoms of the multi-dimensional scalable representation is encrypted using an initialization input to produce an encryption output seed of the logically first atom and an encrypted logically first atom. In addition, the data of other atoms are encrypted to produce encrypted other atoms and an encryption output seed of each encrypted other atom. Encryption of a particular atom of the other atoms includes using encryption output seeds of adjacent causal atoms of the particular atom as an encryption input seed for encrypting the particular atom.

摘要： A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data.
