Encoding and decoding are often computationally intensive and thus can introduce latencies or bottlenecks in the data stream. Often dedicated hardware is required to accelerate encoding and decoding. However, requiring dedicated hardware greatly reduces the market for collaborative video applications. For ...
The low computational complexity of WTHVQ allows 30 frames per second video encoding and decoding in software. Techniques for the design of generic constrained and recursive vector quantizer encoders implemented by table-lookups include entropy-constrained VQ, tree-structured VQ, classified VQ, product...
Scalability at both the encoding and decoding ends is provided by the embedded code. Speed is provided by the use of tables in which everything is pre-computed; by using the hierarchical tables, memory requirements can be made reasonable. Compression effectiveness is enhanced by incorporated block...
