The Sun MediaCenter server implements the “push” model of bit stream delivery. In this model, the server initiates and delivers bit streams over a network interface dedicated to video output. On this interface, there is no “back channel” for decoder-
The push model differs from the “pull” model, in which the receiving device engages a video server in a protocol for connection setup and
The push model has an advantage over the pull model in that receiving devices do not require intelligence for communicating with the server. Receiving devices can be simpler and less expensive than
Consistent with the push model, the Sun MediaCenter server’s supporting software, including the MSM, reflects the
