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.
Table 20.  Video Format Values
Encoding Value SMPTE Standard Active Lines Per Frame Transport Format Frame Rate
0000 SMPTE ST 259 486 I 29.97
0001 SMPTE ST 259 576 I 25
0100 SMPTE ST 274 1080 I 30/29.97/60/59.942
0101 SMPTE ST 274 1080 I 25/503
0110 SMPTE ST 274 1080 P 24/23.98
0111 SMPTE ST 296 720 P 60/59.94
1000 SMPTE ST 296 720 P 50
1001 SMPTE ST 296 720 P 30/29.97
1010 SMPTE ST 296 720 P 25
1011 SMPTE ST 296 720 P 24/23.98
1100 SMPTE ST 274 1080 P 30/29.97/60/59.94
1101 SMPTE ST 274 1080 P 25/50
1110 SMPTE ST 274 1080 I 24
1111 Undetectable format, revert to default value
Others Reserved

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.
Table 21.  Example of 16-bit rx_format for 6G-SDI and 12G-SDI Interfaces
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
2 Frame rates 60 and 59.94 are meant for 3G Level B/HD Dual Link when receiving 1080p60/59.94 format.
3 Frame rate 50 is meant for 3G Level B/HD Dual Link when receiving 1080p50 format.
