Description
VDI-to-VIP mapping
XX000: 8- or 10-bit ITU 656, 8- or 10-bit raw data
VDI_V1-> (clk_vip FF)-> vip_dv_valid
VDI_D[29:20] -> (clk_vip FF)-> vip_dv_data[9:0]
“0”-> vip_dv_d_data[9:0]
Reserved-> (clk_vip FF)-> vip_vrefhd
Reserved-> (clk_vip FF)-> vip_hrefhd
“0”-> vip_frefhd
In 8-bit ITU 656 mode the YUV[7:0] maps to vip_dv_data[9:2],
therefore it maps to VDI_D[29:22]. Similarly in 8-bit raw data mode
VDI_D[29:22] contains the 8-bit data.
Note: H/V sync can only be used when VIP is operated in 8-bit VMI
mode. In that mode the H/V syncs must be connected to VDI_D[20]
and VDI_D[21] respectively.
XX001: 20-bit ITU 656 like for HD
VDI_V1-> (clk_vip FF)-> vip_dv_valid
VDI_D[19:10] -> (clk_vip FF)-> vip_dv_data[9:0]
VDI_D[29:20] -> (clk_vip FF)-> vip_dv_d_data[9:0]
VDI_D[30]-> (clk_vip FF)-> vip_vrefhd
VDI_D[31]-> (clk_vip FF)-> vip_hrefhd
VDI_D[9]-> (clk_vip FF)-> vip_frefhd
HD can be 10- or 8-bit YUV data. In 8-bit mode VDI_D[19:12]
contains the UV data. VDI_D[29:22] is expecting the 8-bit Y data. In
10-bit mode VDI_D[19:10] contains the UV bus. VDI_D[29:20] is
expecting the 10-bit Y data.
XX010: 8-bit ITU 656 or 8-bit raw data
VDI_V1-> (clk_vip FF)-> vip_dv_valid
VDI_D[31:24] -> (clk_vip FF)-> vip_dv_data[9:2]
“0”-> vip_dv_data[1:0]
“0”-> vip_dv_d_data[9:0]
“0”-> vip_vrefhd
“0”-> vip_hrefhd
“0”-> vip_frefhd
XX011: N/A
VDI_V1-> (clk_vip FF)-> vip_dv_valid
“0”-> vip_dv_data[9:0]
“0”-> vip_dv_d_data[9:0]
“0”-> vip_vrefhd
“0”-> vip_hrefhd
“0”-> vip_frefhd
