1. OVERVIEW
1.1. SUMMARY
The 7825DSK2-LG-HD and 7825DSK2-LG-3G Dual Downstream Keyer and Logo Inserter are
complete packages that will insert simultaneous static or animated logos over a full bandwidth SDI
program video signal.
The 7825DSK2-LG-HD and 7825DSK2-LG-3G have been designed to manage and store multiple
logo objects. Logos are stored in non-volatile Flash memory and may be downloaded to the hardware
via Ethernet FTP using the overture™ software. Both models have two sets of key and fill inputs to
allow for external keyer sources. In addition to the support for two external keyers, up to 16 static or
animated logos can be keyed simultaneously with independent fade control for each logo. The size of
each logo is variable and ranges from 1/25th to full screen. The position of the logo, fade rates, and
animation rates are also user controllable. They come with 1GB of playout cache and 2GB of compact
flash storage.
The onboard preview allows you to cue your logos for position and content verification prior to going
"On Air". The optional features of the 7825DSK2-LG-HD and 7825DSK2-LG-3G are an air
temperature probe and a crawl option which provides the ability to insert crawls with static content.
The 7825DSK2-LG-HD and 7825DSK2-LG-3G are VistaLINK®capable, offering remote monitoring,
control and configuration capabilities via Simple Network Management Protocol (SNMP). This product
feature offers another solution to manage operations including signal monitoring and module
configuration from SNMP-enabled control systems (Manager or NMS) locally or remotely.

1.3. DEFINITIONS
4:2:2: The sampling ratio used in the HDTV digital video signal. For every 4 samples of luminance
there are 2 samples each of R-Y (Red minus Luminance) and B-Y (Blue minus Luminance).
16x9: A widescreen television format such as HDTV in which the aspect ratio of the screen is 16
units wide by 9 high as opposed to the 4x3 of normal TV.
AES/EBU:(Sometimes abbreviated as AES) Refers to the digital audio standard (AES3-1992) set by
the Audio Engineering Society and European Broadcast Union and used by most forms of
digital audio from CDs to professional digital video.
Aspect Ratio:The ratio of width to height in a picture. Theatre screens generally have an aspect ratio
of 1.85 to 1, widescreen TV (16x9) is 1.77 to 1, and normal TV (4x3) is 1.33 to 1.
CCIR (International Radio Consultative Committee): An international standards committee. (This
organization is now known as ITU.)
CCIR-601: See ITU-R601.
Cliff effect: (also referred to as the ‘digital cliff’) This is a phenomenon found in digital video systems
that describes the sudden deterioration of picture quality when due to excessive bit errors,
often caused by excessive cable lengths. The digital signal will be perfect even though one
of its signal parameters is approaching or passing the specified limits. At a given moment
however, the parameter will reach a point where the data can no longer be interpreted
correctly, and the picture will be totally unrecognisable.
Component analog: The non-encoded output of a camera, video tape recorder, etc., consisting of the
three primary colour signals: red, green, and blue (RGB) that together convey all necessary
picture information. In some component video formats these three components have been
translated into a luminance signal and two colour difference signals, for example Y, B-Y, R-
Y.
Component digital: A digital representation of a component analog signal set, most often Y, B-Y, R-
Y. The encoding parameters are specified by ITU-R709 for HDTV signals. SMPTE 274M
and SMPTE 296M specify the parallel interface.
Composite analog: An encoded video signal such as NTSC or PAL video that includes horizontal
and vertical synchronising information.
Composite digital: A digitally encoded video signal, such as NTSC or PAL video that includes
horizontal and vertical synchronising information.

D1: A component digital video recording format that uses data conforming to the ITU-R601
standard. Records on 19 mm magnetic tape. (Often used incorrectly to refer to component
digital video.)
D2: A composite digital video recording format that uses data conforming to SMPTE 244M.
Records on 19 mm magnetic tape. (Often used incorrectly to refer to composite digital
video.)
D3: A composite digital video recording format that uses data conforming to SMPTE 244M.
Records on 1/2" magnetic tape.
D5: A component digital video recording format that uses data conforming to the ITU-R601
standard. Records on 1/2" magnetic tape.
Drop frame: In NTSC systems, where the frame rate is 29.97002618 frames per second, the drop
frame mode permits time of day indexing of the frame numbers by dropping certain frame
numbers. Specifically frames 0, and 1 at the beginning of each minute except minutes
0,10,20,30,40, & 50, are omitted, to compensate for an approximate timing error of 108
frames (3 seconds 18 frames) per hour. A flag bit is set in the time code to signal when the
drop frame mode is in effect.
DVS/168: A standard for carrying EAS notifications over TCP/IP. Crawl text (.txt) and sound (.wav)
files are copied via FTP, then activated by a notification over a custom TCP/IP port.
EAS: Emergency Alert System, a national warning system employed in the U.S.
EBU (European Broadcasting Union): An organisation of European broadcasters that among
other activities provides technical recommendations for the 625/50 line television systems.
Embedded audio: Digital audio is multiplexed onto a serial digital video data stream.
ITU: The United Nations regulatory body governing all forms of communications. ITU-R
(previously CCIR) regulates the radio frequency spectrum, while ITU-T (previously CCITT)
deals with the telecommunications standards.
ITU-R601: An international standard for standard definition component digital television from which was
derived SMPTE 125M and EBU 3246-E standards. ITU-R601 defines the sampling
systems, matrix values and filter characteristics for Y, B-Y, R-Y and RGB component digital
television signals.
Letterbox: Placing a wide screen image on a conventional TV by placing black bands at the top
and bottom of the screen.
Linear time code: (Also known as Longitudinal Time Code) A digital code used for timing and
control purposes on videotape and associated audio tape machines. It is recorded on a
linear track with audio characteristics and is referred to as LTC. Each 80 bit code word is
associated with one television frame, and consists of 26 time bits, 6 flag bits, 32 user bits
and 16 sync bits. This time code may run at 24, 25 or 30 frames per second depending on
the video format. See also SMPTE 12M
LTC: See Linear Time Code
