Extensions of ethernet for multimedia transmission

When using a standard Ethernet protocol for the transmission of video and audio, the hard real time requirements of such transmission must be sacrificed. The standard Ethernet protocol does not allow for the guaranteed delivery of media packets on a particular schedule, and so there may be a significant and unpredictable delay that can be seen in the display of the result at the destination. There are ways to adapt the standard Ethernet protocol to allow for real time multimedia transmission and receipt.
