A partial software MPEG-1 decoder
with effective cost and high quality
MetaSound is a cost-effective and high-quality MPEG-1 decoder,
provided by Meta Media Inc. MetaSound is a partial software decoder,
designed to work with hardware video decoders. This solution can
reduce the hardware cost due to no hardware audio decoder required.
In another aspect, MetaSound can support high-quality decoding with
the help of hardware video decoder sharing the computation load.
Currently, MetaSound has been successfully incorporated to work with
three hardware video decoders.
