摘要： Compression transforming video into a compressed representation (which typically can be delivered at a capped pixel rate compatible with conventional video systems), including by generating spatially blended pixels and temporally blended pixels (e.g., temporally and spatially blended pixels) of the video, and determining a subset of the blended pixels for inclusion in the compressed representation including by assessing quality of reconstructed video determined from candidate sets of the blended pixels. Trade-offs may be made between temporal resolution and spatial resolution of regions of reconstructed video determined by the compressed representation to optimize perceived video quality while reducing the data rate. The compressed data may be packed into frames. A reconstruction method generates video from a compressed representation using metadata indicative of at least one reconstruction parameter for spatial regions of the reconstructed video.

摘要： HDR images are coded and distributed. An initial HDR image is received. Processing the received HDR image creates a JPEG-2000 DCI-compliant coded baseline image and an HDR-enhancement image. The coded baseline image has one or more color components, each of which provide enhancement information that allows reconstruction of an instance of the initial HDR image using the baseline image and the HDR-enhancement images. A data packet is computed, which has a first and a second data set. The first data set relates to the baseline image color components, each of which has an application marker that relates to the HDR-enhancement images. The second data set relates to the HDR-enhancement image. The data packets are sent in a DCI-compliant bit stream.

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 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 sequential pattern comprising contiguous black frames inserted between left and right 3D video and/or graphics frames may be displayed on an LCD display. The pattern may comprise two or three contiguous left frames followed by contiguous black frames followed by two or three contiguous right frames followed by contiguous black frames. The left and/or right frames may comprise interpolated frames and/or may be displayed in ascending order. The contiguous black frames are displayed longer than liquid crystal response time. 3D shutter glasses are synchronized with the black frames. A left lens transmits light when left frames followed by contiguous black frames are displayed and a right lens transmits light when right frames followed by contiguous black frames are displayed. A 3D pair of 24 Hz frames or two 3D pairs of 60 Hz frames per pattern are displayed on a 240 Hz display.

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.
