The transport detector also determines
the frame rate of the transport signal. This feature is dependent on the rx_bit_rate input in HD-SDI and 3G-SDI modes to
distinguish between integer and non-integer frame rates. The rx_t_rate port indicates the frame rate of the
transport signal as shown in See Frame Rate Encoding The encoding of the frame rate
matches the encoding used in the picture rate field of SMPTE ST 352 payload ID
packets. However, rx_t_rate shows the
transport frame rate, not the picture rate. Also, the rx_t_rate port value is always the frame rate, even for interlaced
transports.
