Abstract
Transmission power from a home entertainment system server to a client entertainment device in a powerline network is established such that SNR or other reception metric at the receiver is maintained between upper and lower thresholds.
Claims21
A home entertainment system, comprising:
- at least one server;
- at least one client device communicating with the server over a home entertainment network;
- and
- logic executable by at least one of the server and client device for establishing multimedia stream transmitted power such that at least one reception metric at the client device is maintained between upper and lower values.

A method in a powerline network of establishing transmitted signal power from a transmitter of an entertainment data stream to a receiver, comprising:
- initially establishing a high value for transmitted signal power;
- sending at least one tone to the receiver;
- from the tone, determining at least a first reception metric value;
- if the first reception metric value does not exceed an upper threshold, not changing transmitted signal power but otherwise decreasing transmitted signal power, sending another tone, and determining a second reception metric value;
- if a lower threshold is less than the second reception metric, not changing transmitted signal power, but otherwise increasing transmitted signal power.
2 more elements
A home entertainment network, comprising:
- a source of multimedia data streams;
- a player of streams communicating with the source via the network;
- and
- means for establishing transmitted signal power at the source for at least one multimedia stream based on at least one reception metric at the player.
