IP Multicast for broadcasting audio or video.

IP Multicast and real-time encoding allows VideoCharger™ to be used as a broadcast type server in the Internet environment.

A single audio or video stream can be sent to multiple people reducing the bandwidth requirements on the network.
Embedded encoder support lets VideoCharger on Windows NT® directly control the MPEG encoder for functions such as real-time IP Multicast and real-time IP Multicast with live recording of the same stream. This efficient yet powerful method allows simultaneous broadcast of a live event while recording it for later re-broadcast with minimal network load.

The wide range of applicable standards supports home Internet users as well as higher quality streaming for intranet users.

For Internet clients connected with 28.8 Kb modems,

Low Bit Rate video LBR) delivery is based on the Industry Standard H.263 video and G.723 audio.
Using ~ 16 Kb/s, the LBR video will offer 8 KHz 16 bit PCM audio and 160X120 video at 7.5 frames per second.
The LBR video can be encoded at higher quality rates to provide higher resolution or more frames per second for clients connected via ISDN modems, cable modems or an intranet network.

For the intranet environment, VideoCharger provides support for higher quality (and higher bit rate) videos.
