TVB aspect ratio conversions

  • 16x9 SD deliveries for TVB will be letterboxed for parallel 4x3 transmission,
  • 4x3 SD deliveries for TVB will be pillar boxed for parallel 16x9 transmission.
  • Any 4x3 letterbox content will be pillar boxed by TVB for 16x9 parallel transmission resulting in pillar boxed and letterboxed video.
  • TVB will ARC material themselves. Likewise a note on the ARC-ing is needed

SD Title Safety

4:3

All graphics, text, and frame composition elements should be placed within the safe title area to prevent key content from being cut off.


Video Levels

All video signals should comply with BT.601-7 (SD) or ITU-R BT.709-5 (HD) and video signals should not exceed the specified limits.

Video levels should not exceed 700mV, or fall below 0mv

Luminance (Y) -1% and 103%
(ie between -7mV and 721mV)
RGB video levels -5% and 105%
(ie between -35mV and 735mV)

Out of gamut tolerance

Whilst XR and the Broadcasters will reject illegal video levels they understand there may be instances where it is difficult to completely avoid, and following EBU recommendation Rec.103-2000 will allow a small tolerance, assuming that no more than 1% of the active picture is in error.


Audio Levels

Max Peak -10dBFS

  • Permitted Maximum Level : -10dBFS / +10dBu
  • Alignment Level : 1kHz@ -20dBFS
  • Ballistic : PPM Type II
