Abstract: 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.

Abstract: Encoding and decoding architectures for 3D video delivery are described, such as 2D compatible 3D video delivery and frame compatible 3D video delivery. The architectures include pre-processing stages to pre-process the output of a base layer video encoder and/or decoder and input the pre-processed output into an enhancement layer video encoder and/or decoder of one or more enhancement layers. Multiplexing methods of how to combine the base and enhancement layer videos are also described.

Abstract: An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bit-stream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.

Abstract: An apparatus converts an input video signal having a first format into an output video signal having a second format. A formatter receives the first video signal and divides each field or frame into an active video top and bottom half. Two format converters receive and process the two halves of the active video images from the formatter and provide respective halves of the active video image for rejoining into the second format. A demultiplexer receives the two halves of the active video images from the two format converters and combines the active video upper and active video lower halves of the fields or frames into the output video signal having a second format.

Abstract: A laser video disk master is operated at 2.times. speed for duplicating video information to be recorded in VHS format. Two last disk video players are modified to operate in synchronism in order to multiplex from one to the other in duplicating video programs of length equal to the two recorded disks. The 2.times. frequency NTSC format video output signal is then demodulated, drop out detection is performed, and the digitally-encoded stereo audio information is separated, error corrected, and converted by digital to analog (D/A) conversion to left and right channels of stereo analog information. The left and right channels of audio information are presented simultaneously to an FM modulator for presentation to rotating video heads and to a 2.times. Dolby processor for presentation to linear heads. The demodulated 2.times. video information is converted to digital information by an analog to digital (A/D) converter and then time-base corrected and drop out compensated.

Abstract: A system converts digital video signals between two digital video signal formats. The system includes a rate converter which receives digital samples of the video signal in the first format and at the clock frequency thereof and converts those signls to digital samples of the video signal at the clock frequency of the second signal format. The outputs of the rate converter are combined with appropriate coefficients in a digital filter to produce alternately coefficient modified chorma and luminance signals which are combined in an output circuit to produce the digital video signal in the second video signal format.

Abstract: A system is disclosed for encoding and decoding the audio signal portion of a television signal to prevent unauthorized reception of the audio signal. At the encoding stage, the audio signal is applied to a multiplier which combines the audio signal with a programmable carrier having a frequency controlled by a frequency selection protocol to produce an output signal which is spectrally inverted from the original audio signal. The spectrally inverted signal from the multiplier is applied to a sideband filter which filters out the upper sideband of the spectrally inverted signal to produce an encoded signal having the same bandwidth as that of the original audio signal. At the decoding stage, the carrier signal is phase-shifted to compensate for phase delay imparted to the encoded signal in the encoding process and combined with the encoded signal to decode the encoded signal.
