data rate
In Kbps, find details below.
Note: it’s recommended that the [Video Bitrate] should be less
than [modulation data rate] by 20% at least.
If [modulation data rate] is too low, it may cause video glitch.

The modulation data rate ( channel capacity, maximum data bit rate or throughput) varies depending on the
transmission parameters.
The maximum date bit rate can be calculated as below.
Tbandwidth = {1000,000, 2000,000, 3000,000, 4000,000, 5,000,000,6,000,000, 7,000,000,
8,000,000} in Hz for 1~8MHz
Tcode_rate = {1/2, 2/3, 3/4, 5/6, 7/8}
