Ancillary control information from the Xilinx UHD SDI Receiver Subsystem. You must populate these signals manually when UHD-SDI RX Subsystem is not used.

[0] - rx_ce. This signal is the video clock enable from the receiver

[3:1] - rx_mode. This signal indicates the current SDI mode of the receiver
  • 000 = HD
  • 001 = SD
  • 010 = 3G
  • 100 = 6G
  • 101 = 12G 1000/1000
  • 110 = 12G 1000/1001
[7:4] - rx_t_family. This signal indicate the video format family
  • 0000 - SMPTE ST 274 1920 x 1080
  • 0001 SMPTE ST 296 1280 x 720
  • 0010 SMPTE 2048-2 2048 x 1080
  • 0011 SMPTE 295 1920 x 1080
  • 1000 NTSC 720 x 486
  • 1001 PAL 720 x 576
  • 1111 Unknown

[8] - rx_mode_locked. When the receiver locks to the correct SDI mode, the rx_mode_locked goes High.

[9] rx_t_locked. This signal is 1 when the transport detection function in the receiver has identified the transport format of the SDI signal

sdi_extract_anc_ctrl_in

(cont'd)

32 Input
[13:10] rx_t_rate. This signal indicates the frame rate of the transport.
  • 0000 - None
  • 0010 - 23.98 Hz
  • 0011 - 24 Hz
  • 0100 - 47.95
  • Hz 0101 - 25 Hz
  • 0110 - 29.97 Hz
  • 0111 - 30 Hz
  • 1000 - 48 Hz
  • 1001 - 50 Hz
  • 1010 - 59.94 Hz
  • 1011 - 60 Hz
  • Others - Reserved

[14] rx_t_scan. This signal indicates whether the transport is interlaced (Low) or progressive (High).

[15] - rx_rst_int_sys. This signals indicates that UHD-SDI RX Subsystem is under reset. When UHD-SDI RX Subsystem is not used, connect this to rx_fabric_rst_out from drp control engine..

[16] rx_level_b_3g. In 3G-SDI mode, this output is asserted High when the input signal is level B and Low when it is level A.

[19:17] rx_act_streams. This signal indicates the number of data streams that are active for the current video format being received.
  • 000 - 1 active stream
  • 001 - 2 active streams
  • 010 - 4 active streams
  • 011 - 8 active streams
  • 100 - 16 active streams

[31:20] reserved
