The LEI-564 is a product for inserting Active Format Description (AFD) data into an HD/SD video signal. The LEI-564 accepts either SD-SDI or HD-SDI input and transmits a re-clocked signal out through dual SDI outputs.

AFD is a system of codes used to tell DTV receivers, up/down converters, and other professional video equipment, how the video signal is to be displayed, especially if the aspect ratio has changed. AFD in video production is a versatile tool that eases workflow and preserves image quality. Properly managing AFD information is in demand for state-of-the-art digital work-flows. As video productions migrate to storing all their material in HD only and converting to SD as necessary for final transmission, the LEI- 564 offers a simple and reliable solution for adding in AFD for the implementation of the up/down conversion process.

The video signal format can be a 270 Mb/s SD or 1.5Gb/s HD video stream. There is automatic detection of most SD and HD video standards. The signal presence and format are indicated on the display. The AFD data is inserted as vertical ancillary data on video lines allowed per format, selected by the user. The unit is controlled by an 8 character display, with menu navigation by 2 buttons and a rotary encoder.

The 4 modes of operation include; ‘Detect’, ‘Insert’, ‘Delete’ and ‘Auto’. ‘Auto’ is used for inserting AFD, only if there is no AFD detected. ‘Detect’ mode will display the AFD already in the stream. Settings are saved in flash for easy configuration. The unit also regenerates the payload identifier (352M) for all outputs.

The LEI-564 is a one RU chassis that is housed in the same case as the well accepted 700 series. A black front panel distinguishes between the two series. Three 500 or 700 series
