Variable Link Rate Streaming For Audio And Video Content From Home Media Server

An encoder arrangement is provided for streaming media. A variable rate encoder is configured and arranged to receive an input data stream and output an encoded data stream. A buffer is arranged to receive the encoded data stream and output a buffered data stream. A control means monitors depth of the buffer and controls the encoding rate of the variable rate encoder so that encoding is carried out at a rate appropriate to an available link rate, thereby providing smooth transition of data stream quality as link conditions change.
