Technical Specification for Transmission
MTV Networks programming is transmitted via an automated server system, cached from Digital Betacam. Whilst it is possible to use Beta SP, Transmission material is ideally supplied on Digital Betacam, dubbed where possible from the master.
For best audio and video performance please supply material that conforms to the following specifications:

Please Note:
Audio line up tone should be identical in phase on both audio tracks for mono material or audio 1 interrupted tone and audio 2 continuous tone for stereo material.
Ideally, one commercial only should be recorded on each tape that is supplied to MTV Networks. However, multi-segmented tapes can be accepted provided that the time code start and end time for each commercial is clearly marked on the tape or packing slip. Subtitles, where appropriate, should be on line 22 of field 2.
There is a requirement by some broadcasting regulatory bodies that audio should end six to twelve frames before the vision; other adjustments such as frames of black before and after the material, or frozen vision at the end, will be made during the transmission process.
Material supplied on other broadcast formats is not excluded but may cause processing delays.
