6.3.1. rx_format
The format represents only the video transport format; not the picture format. For example, when the core transports 1080p50 video on HD-SDI dual link, the video transport format is 1080i50.

To differentiate video format with 1 and 1/1.001 rate, refer to the rx_clkout_is_ntsc_paln output signal. For example, if rx_format = 0100, rx_clkout_is_ntsc_paln = 1, then the format for the received video is 1080i59.94. Otherwise, it is 1080i60.
To differentiate between video format across HD-SDI and 3G-SDI interfaces, also refer to the rx_std output signal. For example, if rx_format = 1100 and rx_clkout_is_ntsc_paln = 0, rx_std = 01, then the received video format is 1080p30. If the rx_std = 11 or 10, then the received video format is 1080p60.
Note: Intel recommends that you refer to the Payload ID to get the most accurate video format details.
For 6G-SDI or 12G-SDI interfaces, each of the 20-bit interface reports its own detected format. For example, rx_format of all four 20-bit interfaces report 1100 (1080p60) when receiving 2160p60 in 12G-SDI, whereas only the lower two interfaces report valid rx_format in 6G-SDI.
SDI Interface | rx_format | |||
---|---|---|---|---|
[15:11] | [11:8] | [7:4] | [3:0] | |
12G-SDI | 1100 | 1100 | 1100 | 1100 |
6G-SDI | Not valid | Not valid | 1100 | 1100 |
3 Frame rates 60 and 59.94 are meant for 3G Level B/HD Dual Link when receiving 1080p60/59.94 format.
4 Frame rate 50 is meant for 3G Level B/HD Dual Link when receiving 1080p50 format.
