“…Consequently, an iterative bit-allocation algorithm is applied to allocate VQ rate among the spatiotemporal subbands in an optimal fashion. This bit-allocation algorithm, which originates in [13], takes into account a nonnegativity constraint on the rate allocated to each subband. The algorithm indicates the size of the or matrix that minimizes the end-to-end distortion.…”

A scalable video coder consisting of motion-compensated temporal filtering coupled with structured vector quantization plus a linear mapping of quantizer indexes that minimizes simultaneously source and channel distortions is presented. The linear index assignment takes the form of either a direct, uncoded mapping or a coded mapping via Reed-Muller codes. Experimental results compare the proposed system to a similar scheme using unstructured vector quantization as well as to a prominent scalable video coder protected by more traditional convolutional codes. The proposed system consistently outperforms the other two schemes by a significant margin for very noisy channel conditions. Index Terms-Joint source-channel coding (JSCC), scalable video coding.
