+ | To see the SMPTE-352 Link Numbers, enter the following command: | ||
+ | \\ | ||
+ | video status | ||
+ | |||
+ | The output will be similar to the following: | ||
+ | |||
+ | SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 1) | ||
+ | SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 2) | ||
+ | SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 3) | ||
+ | UHD input remapping: none | ||
+ | Video set to 2160p (interleaved format) at 59.94 frames/s | ||
+ | Video source is SDI (video locked) | ||
+ | Action on video loss is freeze frame without ident text | ||
+ | Front panel video monitor source is output 0 to NARA | ||
+ | \\ | ||
+ | We can see in the above example that the SMPTE-352 link numbers are 0-0, 1-1, 2-2 and 3-3, so they are in the correct order. For this reason the line <color red>UHD input remapping</ | ||
+ | \\ | ||
+ | \\ | ||
+ | In the next example, the 3G-SDI inputs have been connected in an incorrect order: | ||
+ | \\ | ||
+ | SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 1) | ||
+ | SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 3) | ||
+ | SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 2) | ||
+ | UHD input remapping: SDI 0 -> UHD 0, SDI 1 -> UHD 1, SDI 2 -> UHD 3, SDI 3 -> UHD 2 | ||
+ | Video set to 2160p (interleaved format) at 59.94 frames/s | ||
+ | Video source is SDI (video locked) | ||
+ | Action on video loss is freeze frame without ident text | ||
+ | Front panel video monitor source is output 0 to NARA | ||
+ | \\ | ||
+ | Here we can see that the SMPTE-352 order is 0,1,3,2. So the last two inputs are swapped. Although the AVP HEVC card can cope with this, and the encode will look fine (because the SMPTE-352 link numbers are present) we can see that the <color red>UHD input remapping</ | ||
+ | \\ | ||
+ | \\ | ||
+ | I tested this in Quad mode (the AJA Ki Pro allows you to select either Sqare or 2SI output) and got the following: | ||
+ | \\ | ||
+ | SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) | ||
+ | UHD input remapping: none | ||
+ | Video set to 2160p (interleaved format) at 59.94 frames/s | ||
+ | Video source is SDI (video locked) | ||
+ | Action on video loss is freeze frame without ident text | ||
+ | Front panel video monitor source is output 0 to NARA | ||
+ | \\ | ||
+ | Here we can see that there are no SMPTE-352 Link numbers present, so perhaps SMPTE-352 Link numbers are only part of the interleaved specification. | ||
