Digital Audio in MAGNUM DVTR

MAGnetoscope NUMerique is the name of the EBU working group which in co-operation with the SMPTE and other parties has proposed a standard for a digital video recorder for professional use. This paper concentrates specifically on the digital audio system of the DVTR and illustrates how the special requirements of video recording have determined many of the parameters, and have resulted in techniques not found in audio only recorders. The block structure of the audio data will be described, in order to illustrate how sectoring is used to permit independent editing of the audio channels. It will be shown that the format permits different degrees of flexibility in audio editing, allowing at one extreme simple circuits for portable recorders and at the other extreme complex post production recorders. The necessary processes to perform track bouncing, synchronous recording, split audio edits and variable crossfade times will be described, and it will be explained why post production machines will need extra heads. A further topic will be the ability to unlock the audio sampling rate from the television frequencies.
