Abstract: A method of distributed statistical multiplexing of video data. The method includes generating a plurality of blocks forming a pre-processed video media corresponding to an original video media, the plurality of blocks including, for one or more sub-portions of the original video media, a plurality of interchangeable blocks that represent the sub-portion. Optionally, at least some of the blocks are transmitted to at least one multiplexer and reconstructed by the at least one multiplexer, for a plurality of communication channels, from at least some of the transmitted blocks.

Abstract: A video stream admission method including receiving one or more parameters of a video stream, indicative of a required bandwidth for the video stream, in a plurality of different quality levels and determining based on the received one or more parameters, whether a channel can meet a predetermined condition for each of the plurality of quality levels, according to an available bandwidth of the channel.

Abstract: A method of media transmission. The method includes providing at least one variable bit rate (VBR) video stream and multiplexing the at least one VBR video stream together with auxiliary data related to the at least one VBR video stream, in a constant bit rate (CBR) stream. The stream is transmitted to a first receiving unit, which is adapted to discard the auxiliary data as padding and use the at least one VBR stream and to a second receiving unit, which is adapted to extract the auxiliary data and use it in further handling of the at least one VBR stream.

Abstract: A method of delivering a video stream, including encoding a video stream into a first encoded stream and selecting encoding parameter values for subsequent transcoding the first encoded stream into a specific second encoded stream. Furthermore, the method includes transmitting the first encoded stream with the selected encoding parameter values to a transcoder over a standard communication network, transcoding the first encoded stream into a second encoded stream having the selected parameter values and forwarding the second encoded stream.

Abstract: The present invention is directed to a method of delivering a video stream. The method operates by determining a group of video streams to be provided to a particular destination over a particular communication link. Next, the band width of the link is allocated to the video streams based upon the particular properties of the various video streams to be transmitted. The video streams are processed so that they fit into the band width allocations. Next, the video streams are transmitted in separate channels, synchronized with respect to each other, to reach the subject destination.

Abstract: A method of providing post-processing information to client decoders. The method includes encoding a video, by an encoder and determining one or more parameters of sharpening, color space bias correction or contrast correction for post-processing of a frame of the encoded video. The method further includes transmitting the encoded video with the determined one or more parameters to a decoder.

Abstract: A method of transmission over a packet based network including providing data packets to be transmitted on the packet based network during a predetermined time interval and arranging the provided data packets in a transmission block according to desired transmission times of the data packets, such that one or more gaps remain between at least some of the data packets. The method further includes adding padding bytes to the transmission block in a manner which substantially fills the one or more gaps and providing the block for transmission on the packet based network.

Abstract: A method of preprocessing a video stream including receiving a video stream formed of a sequence of blocks and setting one or more quality level constraints for the video stream. The method further includes selecting for each of at least a plurality of the blocks of the video stream, one or more sets of compression parameters for compressing the block, such that the block compressed according to the set of parameters meets a respective quality level constraint set for the video stream and generating for each of the sets of compression parameters a corresponding data unit representing the block compressed by the set of compression parameters.
