    摘要: According to one embodiment, video data from a video transmitter (110) is received (420) at a network buffer (130). Information that pertains to a network buffer drain rate (14) of the network buffer (1q3) is monitored (430). The network buffer drain rate (140) is a rate that the video data is removed from the network buffer (130). The network buffer drain rate (140) is estimated (440) based on the monitored information. A transmission rate (120) that the video transmitter (110) transmits future video data is adjusted (450) to not exceed an allowed transmission rate (ATR) that is calculated based on the estimation of the network buffer drain rate (140).

    摘要: A computer-implemented method for encoding using feedback. A base layer of a current frame is encoded. The residue of the current frame is generated. The residue of the current frame is encoded. Also, in response to feedback from a receiver, a coding strategy for each block of the current frame is determined and coding is performed according to one or more of source coding and Wyner-Ziv coding. The feedback is based on the base layer of the current frame and previous correctly received enhancement frames.

    摘要: Adapting characteristics of a video stream. A video stream is received, at a video adaptation device, which employs a first reference frame. A determination is made, at a video adaptation device, to splice the video stream to employ a second reference frame in place of the first reference frame. The video stream is spliced, at a video adaptation device, to create a spliced video stream that employs the second reference frame.

    摘要: A method and system for encoding a video frame. The method includes grouping macroblocks of a video frame into a plurality of groups and determining a first encoding rate for at least one of the plurality of groups based on at least one quantization parameter value associated with the group. The method further includes determining a distortion value associated with the first encoding rate and determining a distortion reduction density value based on the distortion value and the first encoding rate. The method further includes accessing a rate budget associated with the frame and adjusting simultaneously a plurality of quantization parameter values associated with one or more of the plurality of groups.

    摘要: Methods and systems for overcoming the apparent loss of a data packet are described. Encoded second data can be accessed, where the second data is predictively encoded with reference to encoded first data. A data packet that includes at least a portion of the first encoded data can be sent to a downstream device. If the data packet was not properly received by the downstream device, the encoded second data can be adapted to make it decodable independent of the encoded first data.

    摘要: Embodiments of the invention provide a system and method for transferring data on a data network using multiple paths. In one embodiment, data is transferred across a default path of a network. Next, a data loss rate is determined on the default path. When the data loss rate on the default path exceeds a first threshold value, a data loss rate is determined on a first alternate path. Provided the data loss rate on the first alternate path is less than a second threshold value, a first portion of the data is transferred to the first alternate path. Moreover, additional portions of data are transferred to the first alternate path until the data loss rate on the first alternate path meets or exceeds the second threshold value.
