发明名称 Audio data decoder with internal stereo decoder and external multichannel decoder
摘要 <p>Dolby AC-3 and MPEG-2 audio permit the transmission of audio signals being present in packet form, via more than two indepedent audio channels. In case a reproduction device has only a two channel audio decoder (DEC1) an external multi channel audio decoder (DEC2) can be used for a multi channel audio reproduction. According to the invention the first data (A) of the audio data being present in packet form is received by the first decoder for purpose of decoding and is decoded for a first mode of reproduction and fed to a reproduction device. Within a further step said first data (A) is depacketed after reception in said first decoder (DEC1) for decoding for a second mode of reproduction and deposited in a memory and read out and formatted for output to said second decoder (DEC2). &lt;IMAGE&gt;</p>
