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.

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： 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 method and apparatus for performing adaptive stochastic entropy encoding and decoding are provided. Adaptive stochastic entropy encoding may include identifying a current portion of an input video stream, and identifying a current probability distribution, which may be an adapted probability distribution associated with a previously encoded portion of the video stream. Adaptive stochastic entropy encoding may include identifying a forward update probability distribution based on the current portion, generating a modified probability distribution for the current portion based on the forward update probability distribution and the current probability distribution, generating an encoded portion based on the current portion and the modified probability distribution, and generating an adapted probability distribution based on the current probability distribution and the forward update probability distribution.

摘要： A system and methodology provide for generation of a stereo video from a mono video. A mono video is partitioned into shots, where each shot including one or more frames of the mono video. The mono video frames are used as the left frames in the stereo video. Depth parameters are determined for each shot. A pixel depth map is created for each frame of each shot. The right frames for the stereo video are created by shifting pixels from the left frames laterally to occupy new locations in the right frames. A pixel's shift is based on the depth parameters and the pixel depth. In aggregate, pixel shifts will cause objects to appear in different locations in the right frame relative to where they appeared in the left frame. The effect upon the viewer is that the stereo video will provide an enhanced illusion of depth for the viewer.

摘要： A combined depth map is generated for a monoscopic image based on a weighted combination of a color depth map, a spatial depth map, and a motion depth map for the image, each describing the depth of pixels in the image relative to the image plane. The color depth map determines the depth of pixels according to their color, the spatial depth map determines the depth of pixels according to their location in the image, and the motion depth map determines the depth of pixels according to their motion in the image. Each of the depth maps is associated with a weight that is used to generate the weighted combination. The weights are adaptive to account for variation between different monoscopic images.
