The Link Electronics AFD LOG-1864 AFD Insert / Pass / Delete Card adds, detects, and deletes AFD (Active Format Description) data in the HD/SD SDI video signals. It also regenerates the video payload identifier (SMPTE 352M) that is used to describe the video formats. In addition, the AFD card auto detects incoming SD-SDI/HD-SDI signals and transmits re-clocked signal via 2 SDI outputs.
Suitable for use in video production and digital display systems, the device supports video signal formats such as 270 Mbps SD, 1.5Gbps HD, and 3 Gb/s HD video streams. With auto detection feature, the LOG-1864 AFD card can automatically detect SD and HD video standards, and convert them to the desired standards for transmission. The AFD data is keyed as vertical ancillary data on the user selected 8-21 video lines.
In Detect mode, the device checks for current AFD configurations while the Auto mode adds AFD configurations, in case there is no AFD present. The mode settings can be saved in flash for easy configuration.
