Abstract
A client TV in a home entertainment network receives and buffers an audio/video stream from a server, before playing the stream. In the case of buffer underflow, the client TV requests the server to raise the transmission rate. If this causes an ensuing buffer overflow, the client TV requests the server to reset the transmission rate or stop transmitting altogether for a short time.
Claims6
A home entertainment system, comprising:
- at least one server;
- and
- at least one client component communicating with the server on a network path,
- wherein the client component buffers data received from the server and monitors the amount of buffered data, wherein if it is determined that the amount of buffered data falls below an underflow threshold, the client component sends a request to the server to raise the rate at which data is transmitted, wherein a transcoder in the server is used for automatic bit rate control of data transmitted to the client component, and further wherein under unfavorable network conditions the transcoder transcodes a data stream to a lower bit rate stream and sends the lower bit rate stream faster than a normal operating data transfer rate.
