Phabrix PHSXOF – Advanced Video Formats

For broadcast manufacturers this option allows rigorous testing of many more formats, beyond the standard signals used in traditional broadcasting. Among the support for 3G level B on the SxA and SxE is the ability to generate and analyse signals such as SMPTE 425-B carrying 1 x 372M dual link payload. Uniquely the PHABRIX units create three pathological signals in all formats which will be of great interest to broadcast manufacturers. The first is as defined in SMPTE RP198 and is the split field signal with the equaliser test in the first half and the PLL test in the second half. The second and third are separate full-frame EQ test and PLL tests signals. To maintain a regular parity distribution and mitigate any DC offset, the EQ part of the pattern inverts a bit at the start of the first line in each alternate frame. This is the form of 3G Level B Pathological signal that many video manufacturers are adopting as their test signal of choice as it stresses electronic circuits more thoroughly.

This option also supports the new SDI practice for HD and 3G Level A and Level B signal transfer of 2K advanced formats including 4:2:2 Y’C’bC’r, 4:4:4 R’G’B’ and 4:4:4 Y’C’bC’r at 10/12 bit as well as 4:4:4 X’Y’Z’ at 12-bit.

This allows analysis of, and test pattern generation for, 2K digital cinema as defined in the SMPTE ST 2048-2:2011 standard (“2048 x 1080 Digital Cinematography Production Image FS/709 Formatting for Serial Digital Interface”) and SMPTE 428-9 (D-Cinema Distribution Master – Image Pixel Structure Level 3 – Serial Digital Interface Signal Formatting).
