| | Audio & video codecs |
 | | There are many audio conferencing software out there and some of the software use research algorithms for their compression of audio signal while some have their own proprietary compression algorithm. | | | There are so many software out there and many of them use compression techniques that I have studied or at least heard of during the four years studies in computer engineering. | | | By having their own algorithm and that means that their competitor software would not be able to communicate with their software. |

| | Understanding Video and Audio Codecs |
| | The term "codec" is an acronym that stands for "compressor/decompressor." A codec is an algorithm – a specialized computer program – that compresses data when you are recording and producing a movie and then decompresses the data when the movie is being viewed. | | | For example, an AVI movie file – the file type of movies created by Camtasia Recorder – compressed using the Microsoft Video 1 codec can be played only on a computer on which the MS Video 1 codec is also installed. | | | When implemented, these compression algorithms are called codecs. |

| | LinuxElectrons™ - SigmaTel Cranks Volume on Audio Codecs |
| | In the summer of 2002, through input from Intel and Microsoft, SigmaTel wrote the first concept initiative for allowing a system to detect and auto-configure the audio jacks, and hence coined the term "Universal Jacks." At IDF Fall 2002, SigmaTel introduced and successfully demonstrated the first audio codec with Universal Jacks(tm) functionality, the STAC9758. | | | C-Major hardware and software were used in this demonstration to illustrate the functionality of the future Azalia specification. | | | Universal Jacks(tm), which was highly regarded, was placed on the standard's feature list and was used within the Intel concept platform Powersville 2003 demonstration, which featured dual STAC9758 codecs with Universal Jacks. |
