Design of a DVD-AV receiver using a single-chip DVD processor

The recent successes of DVD players in consumer electronics, combined with a constant evolution of audio compression formats, necessitate the integration of DVD players with AV (audio/video) receivers. Traditional DVD-AV receivers use board-level integration of separate DVD player and AV-receiver ICs. We present a more cost-effective approach using a single-chip DVD processor. In addition, we describe a modular audio processing pipeline with five main components: the DSP operating system; the DSP application programming interface; the compressed data decoder; the matrix decoder; the audio post-processor.
