General Description

FEATURES

 AFD Insertion
 AFD Deletion
 AFD Monitor (pass thru)
 Auto Insert (only if AFD is not there)
 Selectable 352M (VPID) insertion
 User Programmable Settings
 SD/HD/3G SDI I/O

The LEI-564 is a product for inserting Active Format Description (AFD) data into
an SD/HD/3G, multi-definition (MD), SDI video signal. The LEI-564 automatically
detects whether the input is SD-SDI, HD-SDI, or 3G-SDI and transmits a re-clocked
signal out through two 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, 1.5Gb/s HD, or 3Gb/s HD video
stream. There is automatic detection of most MD 4:2:2 video standards. The signal
presence and format are indicated on the display. The AFD data is inserted as vertical
ancillary data on video lines 8-21, 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 has an option to regenerates the video payload identifier (VPID) SMPTE 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 can be mounted in the PRT-700 rack tray.

LEI-564 12

Information Display

The information display is used to tell the user what type of input the unit sees,
the AFD mode the unit is in, and the AFD code. Pressing escape from here will
temporarily bring up the model number and firmware version of the unit. Pressing enter
from here will temporarily bring up the video format display. Turning the rotary encoder
knob will bring up the menu options.

The information display consists of three sets of two characters. The first set is

the input video standard, which are SD, HD, or 3G. The second set is the AFD mode
that the unit is in which are AU (auto), DT (detect), DL (delete), or IN (insert). The third
set is the AFD code 0-15 or XX (none) being inserted, deleted, or detected depending

on which mode the unit is in. Example:

HD IN 10

From the above information display sample, we can see that the input is high
definition; the AFD mode is insert, and is inserting the AFD code 10.

The AFD code of the information display can be what the unit is detecting on the
input or what the unit is inserting depending on the AFD mode and the input.

In insert mode the AFD code is what the unit is inserting. The escape LED will
be lit and the enter LED will be blinking if AFD is detected on the input.

In detect mode the AFD code is the detected AFD code on the input. The
escape LED will not be lit and the enter LED will be lit if AFD is detected on the input.

In delete mode the AFD code is the detected AFD code on the input. The
escape LED will not be lit and the enter LED will be blinking if AFD is detected on the
input.

In auto mode the AFD code is the inserted code when no AFD code is detected
on the input. The escape LED will be lit and the enter LED will not be lit. However, in
auto mode the AFD code is the detected code when AFD has been detected on the
input. The escape LED will be blinking and the enter LED will be lit.

LEI-564 15

AFD-Line

This menu allows you to select the line for the current format in which the AFD
code is to be inserted. The options are as follows:

8 - 20

For HD the lines are 9 - 19, for SD PAL the lines are 8 - 21, and for SD
NTSC the lines are 12 - 19. SMPTE states that the preferred line to insert AFD on is
the fourth line from the vertical switching line, line 11 for HD, line 10 for PAL, and
line 14 for NTSC.

Note: For interlaced and progressive segmented frame formats the unit places AFD on

the same line for field 2 as it does for field 1.

Set-Save

This menu allows you to save the current settings as the power up settings.
Pressing enter saves the settings and returns you to information display.

Set-Load

This menu allows you to load the power up settings as the current settings.
Pressing enter loads the settings and returns you to information display.

Set-Dflt

This menu allows you to load the factory default settings as the current settings.
Pressing enter loads the factory default settings and returns you to information display.
The factory default settings are:

AFD mode: Auto
AFD code: 8
AFD line: 10 PAL, 14 NTSC, 11 HD
3G Dat: Link 1
352 mode: Pass
PSF mode: Auto

Note: To get unit to power up factory defaults you must load defaults then save settings.

LEI-564 16

352-Mode

This menu allows you to select whether the Video Payload Identifier (VPID)
(SMPTE 352M) is to be inserted or passed thru. The options are as follows:

352-Pass

352-Rgen

The default for this menu is normally set to pass, which means that the
VPID will pass thru the unit unchanged. However, you can set this menu to Rgen
and it will generate (or regenerate) and insert the correct VPID for the format.

Note: this can be useful if the VPID is missing or wrong.

PSF-Mode

This menu allows you to select how the progressive segmented frame formats
are indentified. The options are as follows:

PSF-Auto

PSF- Off
PSF- On

This menu should normally be set to auto, which means it automatically
reads the VPID PsF flag, if present, to distinguish between PSF and interlaced
formats. Turning the PSF-Mode on or off will manually set the PSF flag. This
maybe required for 1080 PsF or interlaced formats at the frame rates of 30, 29, and
25, and the video input VPID is wrong or missing.

Note: if the PSF-Mode is set to auto, and there is no VPID present the unit will detect

PsF formats with frame rates of 30, 29.97 and 25 as interlaced formats. In these cases
you will need to set the PSF-Mode to on to get the unit to properly indentify these
formats and to properly insert VPID.
