Wireless Multimedia Streaming

Purpose: Essential to provide seamless quality

experience for audio and video transmissions

MPEG-4 has been selected by Wireless Multimedia Forum (WMF) and the 3rd Generation Partnership Program (3GPP) for use in the mobile environment.

MPEG-4

What: Graphics and video compression algorithm standard that is

based on MPEG-1 and MPEG-2 and Apple QuickTime technology.

Wireless Compatibility: MPEG-4 files are smaller than JPEG or QuickTime files are

designed to transmit video and images over a narrower bandwidth and can mix video with text, graphics, 2-D and 3-D animation layers.

MPEG-4’s Wavelet technology can compress color images enormously making it suitable for wireless devices constrained by resources
