Abstract: A video signal is encoded in a progressive video coder so as to generate a progressive coded video bit stream for transmission over a heterogeneous network. The progressive coded video bit stream is configured so as to be decodable at any one of a series of increasing bit rates up to a maximum bit rate, depending on which of a number of corresponding portions of the progressive coded video bit stream are received by a decoder. Each of the portions is associated with a different bit rate, and one or more of the portions may each also be associated with different values of other parameters such as frame rate, spatial resolution, and peak signal-to-noise ratio. Each of the series of increasing bit rates produces progressively better reconstructed video quality at an output of the decoder. The progressive coded bit stream is transmitted over a first part of the heterogeneous network at a first one of the bit rates.

Abstract: A system and method are disclosed for providing immersive visualization at low bandwidth rates. The system retrieves a frame of multimedia information for transmission over a network and converts the frame from a first color space to a second color space. The system slices the frame into a plurality of frame slices and transforms each of the plurality of frame slices into a plurality of corresponding frequency domain components. The system quantizes the frequency domain components of each frame slice, when the frame slice to be processed is an intra-slice or a refresh slice, to generate quantized frequency domain components of each frame slice. The system variable-length encodes the quantized frequency domain components of each frame slice to generate compressed multimedia information associated with each frame slice. The system constructs network packets of the compressed multimedia information associated with each frame slice, and transmits the network packets via the network.

Abstract: Unequal channel error protection is provided for a bit stream, e.g., a progressive source coded bit stream, by puncturing of a channel code. The channel code has a specified rate associated with a corresponding level of error protection, and is used to code a first portion of the bit stream. The channel code is subsequently punctured for at least a second portion of the bit stream so as to provide a rate higher than that of the designated rate. Commencement of the puncturing is deliberately delayed by an amount determined based at least in part on a memory of the channel code. Advantageously, the delay prevents propagation of errors in a channel decoder used to decode the channel coded bit stream. The progressive bit stream may be a progressive source coded video or audio bit stream, any other type of progressive information bit stream, or a partitioned source coded bit stream.
