A system and method for synchronizing digital media playback at multiple digital media playback devices interconnected on a network is provided. A digital media playback device comprising a processor, a synchronization component, a timekeeper component and a digital media source performs synchronization processes to arrange for other players to begin playback at a predetermined position and time in the digital media signal. Synchronization is accomplished by processes which approximate the arrival time of a packet containing audio and/or video digital content across the network and instruct the playback devices as to when playback is to begin, and at what point in the streaming media content signal to begin playback. One method uses a time-stamp packet on the network to synchronize all players. Other methods utilize reiterative processes to narrow approximations of packet arrival time at each playback device.

A system and method for automatically sets the encoding bit-rate across a network. The method includes encoding an original media stream with an encoding bit rate having an adjustable rate, transmitting the encoded media stream to a receiver, monitoring a throughput of the encoded media stream, computing an adjustment to the encoding bit rate, and adjusting the encoder's encoding bit rate. A throughput monitor (which can be freestanding, part of the transmitter, or part of the receiver), is operable to monitor the encoded media stream, wherein the transmitter is operable to adjust the encoding bit rate using a result of the monitored throughput. The transmitter and receiver both contain a buffer, and respective buffer monitors. Conditions (e.g., overflow, full, empty) at the transmitter or receiver buffer are detected by the respective transmitter or receiver buffer monitor, where upon a repeated condition the encoded bit rate is adjusted higher or lower.

A controller is connected to one or more media devices. Each media device includes an associated native remote control. The controller includes a data store comprising one or more descriptions of remote control protocols. The user presses a button on the native remote control. The controller receives a resulting signal and compares the signal against the stored remote control protocols. After at least one and preferably less than three key presses, the controller identifies a single remote control protocol associated with the received signals, and thus identifies the media device whose remote control is being used. The user may subsequently use a controller remote control to issue commands to the media device through the controller. The controller may identify a plurality of media devices, and allow the user to issue complex commands. The controller may receive updates to its data store from a server through a network connection.
