FSD-8240 is an HD/SD-SDI frame synchronizer and Dolby decoder with 16-channel of audio embedding or de-embedding. When Dolby digital or Dolby E is present on a discrete AES pair or on an embedded audio pair, the decoder produces up to 10 decoded channels, according to the Dolby sub-format received by the metadata. The resulting channels are then available for mapping, inversion and level adjustment and then embedded into the video signal.
