C h a p t e r 6 Setup Menu P h as e B i t s Phase Bits For units with SDI de-embedder cards installed, there is a new menu item available, entitled Phase Bts, which stands for phase bits. These are bits that are embedded in SDI streams that allow the audio sample rate to be independent of the video pixel clock, and they are required by the latest SMPTE standards. However, not all equipment implements these bits correctly.
