An Apple patent (number 7895045) for bitrate constrained variable bitrate audio encoding has appeared at the US Patent & Trademark Office. A hybrid audio encoding technique incorporates both ABR, or ...

In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.

How does one improve video encoding performance on the Texas Instruments TMS320C64x/TMS320DM64x digital signal processor generation? The conventional implementation of a video encoder (MPEG-2, MPEG-4, ...

The general definition of quantization states that it is the process of mapping continuous infinite values to a smaller set of discrete finite values. In this blog, we will talk about quantization in ...

The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, the ...
