摘要： A video processing device may generate a two dimensional (2D) output video stream from a three dimensional (3D) input video stream that comprises a plurality of view sequences. The plurality of view sequences may comprise sequences of stereoscopic left and right reference fields or frames. A view sequence may initially be selected as a base sequence for the 2D output video stream, and the 2D output video stream may be enhanced using video content and/or information from unselected view sequences. The video content and/or information utilized in enhancing the 2D output video stream may comprise depth information, and/or foreground and/or background information. The enhancement of the 2D input video stream may comprise improving depth, contrast, sharpness, and/or rate upconversion using frame and/or field based interpolation of images in the 2D output video stream.

摘要： A video processing system receives left and right 3D video and/or graphics frames and generates noise reduced left 3D video, right 3D video and/or graphics frames based on parallax compensated left and right frames. Displacement of imagery and/or pixel structures is determined relative to opposite side left and/or right frames. Parallax vectors are determined for parallax compensated left 3D video, right 3D video and/or graphics frames. A search area for displacement may be bounded by parallax limitations. Left 3D frames may be blended with the parallax compensated right 3D frames. Right 3D frames may be blended with the parallax compensated left 3D frames. The left 3D video, right 3D video and/or graphics frames comprise images that are captured, representative of and/or are displayed at a same time instant or at different time instants. Motion estimation, motion adaptation and/or motion compensation techniques may be utilized with parallax techniques.

摘要： A video receiver receives a compressed 3D video comprising a base view video and a residual view video from a video transmitter. The video receiver decodes the received base view video and an enhancement view video of the received compressed 3D video into a left view video and a right view video. Base view pictures are generated selectively based on available memory resource. The residual view video is generated by subtracting base view pictures from corresponding enhancement view pictures. The received base view and residual view videos are buffered for video decoding. Pictures in the buffered residual view video are added to corresponding pictures in the buffered base view video for enhancement view decoding. The left view video and/or the right view video are generated from the resulting decoded base view and enhancement view pictures. A motion vector used for a disparity predicted macroblock is applied to adjacent macroblock pre-fetching.

摘要： A video receiver receives a compressed 3D video comprising a base view video and an enhancement view video. The base view video and the enhancement view video are encrypted using same encryption engine and buffered into corresponding coded data buffers (CDBs), respectively. The buffered base view and enhancement view videos are decrypted using same decryption engine corresponding to the encryption engine. The decrypted base view and enhancement view videos are decoded for viewing. The video receiver is also operable to encrypt video content of the received compressed 3D video according to corresponding view information and/or coding layer information. The resulting encrypted video content and unencrypted video content of the received compressed 3D video are buffered into corresponding CDBs, respectively. The buffered encrypted video content are decrypted and are decoded together with the buffered unencrypted video content of the received compressed 3D video for reviewing.

摘要： A video processing device may generate and/or capture a plurality of view sequences of video frames, decimate at least some of the plurality of view sequences, and may generating a three-dimension (3D) video stream comprising the plurality of view sequences based on that decimation. The decimation may be achieved by converting one or more of the plurality of view sequences from progressive to interlaced video. The interlacing may be performed by removing top or bottom fields in each frame of those one or more view sequences during the conversion to interlaced video. The removed fields may be selected based on corresponding conversion to interlaced video of one or more corresponding view sequences. The video processing device may determine bandwidth limitations existing during direct and/or indirect transfer or communication of the generated 3D video stream. The decimation may be performed based on this determination of bandwidth limitations.

摘要： A media player may read three-dimensional (3D) video data comprising a plurality of view sequences of frames or fields from a media storage device, and may decimate one or more of the view sequences to enable transferring the video data to a display device. The media player may determine operational parameter(s) and/or transfer limitation(s) of a connecting subsystem used to transfer the video data to the display device. The decimation may be performed based on this determination of transfer limitation(s). The decimation may be performed temporally and/or spatially. The plurality of view sequences may comprise sequences of stereoscopic left and right view reference frames or fields. The decimation may be performed such that the removed data for each view sequence may be reconstructed, after reception, based on remaining data in the same view sequence and/or video data of other corresponding view sequences.

摘要： A video transmitter identifies regions in pictures in a compressed three-dimensional (3D) video comprising a base view video and an enhancement view video. The identified regions are not referenced by other pictures in the compressed 3D video. The identified regions are watermarked. Pictures such as a high layer picture in the base view video and the enhancement view video are identified for watermarking. The identified regions in the base view and/or enhancement view videos are watermarked and multiplexed into a transport stream for transmission. An intended video receiver extracts the base view video, the enhancement view video and corresponding watermark data from the received transport stream. The corresponding extracted watermark data are synchronized with the extracted base view video and the extracted enhancement view video, respectively, for watermark insertion. The resulting base view and enhancement view videos are decoded into a left view video and a right view video, respectively.

摘要： A 2D and/or 3D video processing device comprising a camera and a display captures images of a viewer as the viewer observes displayed 2D and/or 3D video content in a viewport. Face and/or eye tracking of viewer images is utilized to generate a different viewport. Current and different viewports may comprise 2D and/or 3D video content from a single source or from different sources. The sources of 2D and/or 3D content may be scrolled, zoomed and/or navigated through for generating the different viewport. Content for the different viewport may be processed. Images of a viewer's positions, angles and/or movements of face, facial expression, eyes and/or physical gestures are captured by the camera and interpreted by face and/or eye tracking. The different viewport may be generated for navigating through 3D content and/or for rotating a 3D object. The 2D and/or 3D video processing device communicates via wire, wireless and/or optical interfaces.

摘要： A video processor decompresses stereoscopic left and right reference frames of compressed 3D video. New left and right frames are interpolated. The frames may be stored and/or communicated for display. The left and right frames are combined into a single frame of a single stream or may be sequenced in separate left and right streams. The left and right frames are interpolated based on the combined single stream and/or based on the separate left and right streams. Motion vectors are determined for one of the separate left or right streams. The frames are interpolated utilizing motion compensation. Areas of occlusion are determined in the separate left and right streams. Pixels are interpolated for occluded areas of left or right frames of separate streams from uncovered areas in corresponding opposite side frames. The left and right interpolated and/or reference frames are displayed as 3D and/or 2D video.
