GIPS Codec Now Powers Yahoo Video Calling

When it comes to real-time Internet communication, quality is always an issue. Internet connections are so inconsistent they can turn talk into gibberish. It takes sophisticated technology to make Internet conversations sound consistently good. The challenges are even greater with Internet video calling. The quality of both images and sound has to be good, and the two must also be in sync. That's why companies that can afford it pay lots of money for custom video equipment connected over private IP links.

Codecs are key to making Internet voice and video work. These pieces of software, embedded in physical phones or Internet calling applications, process the audio and video for delivery over IP connections. Among other things, codecs adjust for different levels of Internet bandwidth between callers, and compensate for delay, inconsistent delivery and loss of packets carrying the voice or video streams.
