Video Levels

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

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

Luminance (Y) -1% and 103%
(between -7mV and 721mV)
RGB video levels -5% and 105%
(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. Following EBU recommendation Rec.103-2000 they will therefore 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

Clearance

Do you need help with clearance or regulatory compliance?

XR's Campaign Services teams can assist you! Please reach out to your local team for more information, addtional fees apply.

Clearance in this region is generally managed locally. Chinese broadcasters normally provide free clearance services to local media buyers. The decision made by vetting department of each broadcaster is the final. 
The Governing body handling broadcast censorship clearance in China is CAA (China Advertising Association). They will charge a service fee depends on different type of Ad and duration.
CAA clearance is an industry guideline in China and is not mandatory. However, it does provide an accurate guideline on censorship in China and broadcasters are more likely to accept and clear a TVC quickly if CAA certification is included.
