摘要： Video-coded information is transmitted over a network at a priority level that is determined based on feedback from the network. In an embodiment, the feedback comprises a response to a request for information on whether the network currently has the available capacity to transmit additional high priority traffic. In an embodiment, a candidate base layer frame is transmitted over the network as a base layer frame if permission to send high priority data was granted and is transmitted over the network as an enhancement layer frame if permission to send high priority data was denied. In a further embodiment, the candidate base layer frame is deleted if permission to send high priority data was denied.

摘要： Systems and methods of perceptual quality monitoring of video information, communications, and entertainment that can estimate the perceptual quality of video with high accuracy, and can be used to produce quality scores that better correlate with subjective quality scores of an end user. The systems and methods of perceptual quality monitoring of video can generate, from an encoded input video bitstream, estimates of one or more quality parameters relating to the video, such as the coding bit rate parameter, the video frame rate parameter, and the packet loss rate parameter, and provide these video quality parameter estimates to a predetermined video quality estimation model. Because the estimates of the video quality parameters are generated from the encoded input video bitstream as it is being received, the systems and methods are suitable for use as QoE monitoring tools.

摘要： Apparatus and method of transmitting a video bitstream from a transmitter over a facility to a receiver, the video bitstream including a plurality of high priority segments and associated low priority segments, is disclosed. The transmitter first transmits high priority information, representative of the high priority segments, of the video bitstream over the facility using a first packet delivery mechanism having a first probability of success and subsequently transmits a low priority partition, including the low priority segments, of the video bitstream over the facility using a second packet deliver mechanism having a second probability of success which is substantially lower than that of the first delivery mechanism. At the receiver, the high priority partition is received and used to generate the high priority segments. When each low priority segment of the low priority partition is received, the associated high priority segment is interleaved in real time with the received low priority segment to create an interleaved video bitstream. The high priority information may be sent as a high priority partition (including the high priority segments), sent as a high priority format (used by the receiver to generate high priority segments), or sent as a high priority identifier (used to identify previously stored high priority segments at the receiver).

摘要： The described video communication system incorporates multiple window display. One or more video transmission nodes provide macroblocks of video data available in a plurality of resolution levels. The transmission node encodes the macroblocks and assigns macroblock identifiers (IDs) to each macroblock. A receiving node receives a plurality of video sequences from a plurality of transmission nodes through a communication network. The receiving node thereafter eliminates macroblocks of video data that will not be displayed, such as in the case of portions of video that are hidden or overlapped. A macroblock translator also transforms the macroblock ID to a new macroblock ID which reflects the macroblock's position on the display screen as dictated by the user's window configuration. A decoder thereafter decompresses the video data one macroblock at a time, and provides the decompressed macroblock to a frame buffer. The frame buffer provides the window configured video data to a display.

摘要： A fast pipeline adder comprising a plurality of registered adder rows. In one embodiment, additions in the pipeline are realized in reclocked half adders. In another embodiment, modified adders are employed which accept two carry inputs and develop two carry outputs. The resulting number of individual cells is reduced to approximately half of those in the prior embodiment. In still another embodiment, switch means are included in each cell to delete the reclocking and in still another embodiment, the adders in the diagonal of the pipeline adder are provided with additional inputs to permit use of the pipeline adder in recursive addition applications. In still another embodiment, the cells are permitted to output the inverse of the intended signal, reducing thereby the physical realization of the cells and increasing the speed of the cells.

摘要： Apparatus for and method of sending a video bitstream, including a plurality of high priority segments and associated low priority segments, by transmitting only the low priority segments from a transmitter over a facility to a receiver is disclosed. The transmitter and receiver locations are arranged to use previously agreed-to high priority information (e.g., predefined high priority segments or format for generating same) and, consequently, only the low priority segments of the video bitstream need to be transmitted to the receiver. At the receiver, the high priority segments are obtained (from storage or generated using the agreed-to format) and interleaved in real time with the received low priority segments to recreate an interleaved video bitstream.
