Carrying Specialist video around IP networks has Unique issues as compared to most non-time-crucial IP targeted traffic. Lots of of these difficulties are just like Those people encountered in voice more than IP, but to far more stringent engineering prerequisites.

Codecs have become extra productive on the desktop: Apple and Microsoft are jogging neck and neck in the quality/bandwidth race. Both equally of their codecs (H.264 and VC-1, respectively) might be included in another generation of DVDs, which aid HD (superior definition) and run within the desktop by way of QuickTime or Windows Media Player.
