Dolby-E Alignment
It is important to maintain a proper timing relationship between the Dolby-E header and the
first line of video especially when recording video with embedded audio on tape transports.
This is commonly known as the
guard band . On the X50, the Dolby-E alignment timing is
determined by the value of the SDI 1 or SDI 2 Dolby E Start Line embedder controls in
EMB x >Controls .
Note: If Dolby E is embedded, the module’s output frame rate must match the frame rate
of the Dolby E stream.
