Fig. 6-6: Imagestore 750 example - A/B Mixing PCM and decoded Dolby audio
It is now possible to A/B-mix decoded Dolby from the input sources and to apply voice-overs
prior to re-encoding.
Additionally, it A/B-switches incoming input Dolby metadata and uses the metadata to re-
encode the output. (The switched metadata are also available in a serial form).
