VBrick Systems VB6000, VB4000 Typical VBrick Applications, Standard Features, Encoder, Reflector

•Microsoft Windows Media Player 7.1 (Windows 98 or 2000 only); Media Player 9, 10, or 11 (Windows XP only).

Standard Features

The VB6000 WM Appliance supports approximately 40 Mbits/sec total throughput via the Ethernet/IP connection. This bandwidth can be used for any of the standard features shown in Table 1 but the overall performance of any one of these features can be affected by the sum total. For example, you can download more content from the hard drive when the encoder(s) are not streaming, pushing, and/or multicasting. In a typical scenario, the hard drive will support the progressive download of a video file to a maximum of 20 simultaneous viewers, or 20 MBits/sec—whichever comes first.
