Adapting characteristics of a video stream. A source video stream is received comprising instructions to employ at least one reference frame at a video adaptation device, wherein the source video stream is encoded. The source video stream is adapted, at the video adaptation device, such that the instructions are adapted to store a different number of reference frames. A video stream is produced with the different number of the reference frames.

Methods for adapting the sliding window of sliding window-based error correcting codes based on the coding structure of a compressed media stream are disclosed. In one aspect, a sender packetizes each frame of a media stream to be sent to a receiver into a set of frame packets. The sender also determines compression dependence of each frame and adapts a sliding window of a sliding window-based error correcting code based on the compression dependence of the frame. The sender encodes the frame packets into at least one associated parity packet according to the error correcting code with the adapted sliding window, and sends the frame packets and the at least one associated parity packet to the receiver.

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.

A visual-collaborative system including a display screen configured to display images captured at a remote location and a camera configured to capture an image of an object to be transmitted to a remote location. The visual-collaborative system also includes a privacy controller configured to transmit the image comprising a first fidelity in response to the object located in a designated proximity area and to transmit the image comprising a second fidelity in response to the object located outside the designated proximity area.
摘要:
A powerful new class of methods for encoding digital data for reliable transmission over unreliable communication channels is described. With this method, the message bits are divided into multiple submessages and the bits in each layer are encoded using a standard error correction code to provide a plurality of subcodewords. A first linear transformation is applied to each of the subcodewords. The so-transformed subcodewords from the different submessages are then combined to form a first redundancy block to be transmitted. Additional redundancy blocks are generated by repeating this process on the same message but with jointly related nonidentical sets of linear transformations. The result is a set of codewords for each message which are then used to generate a transmitted waveform in one of several different ways, depending upon the application. For example, the codewords can be used in sequence (temporally) to form a rateless code for transmission over channels of unknown quality, in which case a receiver accumulates as many of the codewords as are necessary to successfully decode. As another example, the codewords can be spatially distributed if the channel has multiple-inputs, as would be the case in a multi-antenna system. As still another example, the codewords can be distributed over subchannels in a frequency-division multiplexing system.
