DYNAMIC QoS IN A NETWORK DISTRIBUTING STREAMED CONTENT
First Claim
1. A method of providing dynamic QoS in a network distributing streamed content, the network comprising one or more receiving devices for playing streamed content, one or more source devices for the content, and control means for routing the content from a selected source device to a selected receiving device upon request by the selected receiving device, the method comprising:
- setting a priority for the content to be output from a selected source device dependent upon the characteristics of that content stream, anddetermining the throughput rate of content streams from each of the sources in the network in dependence upon the priority set for each content stream.

Abstract
In a home network a number of receiving devices are connected to receive streamed audio visual content from one or more sources by way of a network hub. One source is a set top box, having a hard disc drive, which provides a real time broadcast stream, stream 1, as well as a recorded output stream, stream 2. Another source is local storage which is capable of outputting its stored content, stream 3, at x32 normal speed, that is, fast forward. If there are bandwidth limitations on the network then the receiver (receiving the fast forward stream 3 will experience errors. When errors are detected, the receiver sends a message back to the source which then takes action to reduce the bit rate of its output stream.

12. A network distributing streamed content, the network comprising
one or more receiving devices for playing streamed content, one or more source devices for the content, and control means for routing the content from a selected source device to a selected receiving device upon request by the selected receiving device, wherein each source device is enabled to set a priority for the content stream to be output dependent upon the characteristics of the content stream, and wherein the network is arranged to determine the throughput rate of content streams from each of the source devices in dependence upon the priority set for each content stream.
