Abstract

A digital media distribution device that includes an encoder, a decoder coupled to the encoder, and a transcoder coupled to the decoder. The encoder is configured to encode input data that is received by the digital media distribution device into a first data format. The decoder is configured to decode output data to be output by the digital media distribution device. The transcoder is configured to convert the encoded input data from the first data format into a second data format. The digital media distribution device is configured to be coupled to a computer network.
