it can replace MPEG-2 and provide better-quality video using the same number of bits. For high resolutions, it can ramp up to 2 Mbps for film-quality video over enterprise networks. If you think your MPEG-2 server is providing sufficient quality, an MPEG-4 server--like VBrick Systems' VBXcast, Starbak's Torrent OSA or even Apple's QuickTime Streaming Server 5 (built into OS X)--can give you the same quality but use less bandwidth.
And if bandwidth is a concern, you should look at other software that can deliver high quality over impoverished networks, like Microsoft's Media 9 Series or RealNetworks' Helix Universal Server. MPEG-4 also can better manage and protect enterprise content owners.
