VAM6800 A/D Conversion and Audio Embedder - 4 -

Chapter 1 Introduction

Overview

In this manual, the analog video module and audio embedder module for VAM6800 are introduced.
The modules for VAM6800 include decoder and line buffer that can remove the jitter, one analog video

input, two balanced analog audio inputs and three SDI outputs with embedded audio.
The VAM6800S has one analog video input, one analog reference input, two balanced analog audio

inputs and three SDI outputs with embedded audio. In addition to the functions that VAM6800 provides,
the VAM6800S also features in frame synchronizer and can synchronize to the external reference signal.
The system synchronization must be in consistency with the standard of analog composite input,
otherwise the VAM6800S cannot work properly. It prefers BB signal as system synchronization and it
must comply with standard of analog composite signal.
The VAM6800 can be housed in 6800N series frame.

General Description

The VAM6800 is a decoder and audio embedder with broadcast quality. It converts analog composite
NTSC/PAL signal and analog audio signal into SDI component signal with embedded audio. The
VAM6800 can be used in the broadcast and production system, where converting analog composite
video and audio signal into SDI component signal with embedded audio is required.

The VAM6800 incorporates the latest technology in circuit design and low power dissipation. Each card
can complete a variety of functions, such as the conversion between A/D, frame synchronization and
embedded audio. The VAM6800 can output three SDI component signals (SMPTE-259M)
simultaneously. The VAM6800 provides multi-function on card-edge.

The VAM6800 analog video and audio embedder can be controlled via the switches on the front panel.
Table 1-1 is the description for different modules.

Module Description

VAM6800 Analog audio embedder, with three SDI outputs with embedded audio.
VAM6800S Analog audio embedder, with three SDI outputs with embedded audio,

and frame synchronizer.

Features

 Compact Design

The VAM6800 includes 12-bit A/D conversion, 4X oversampling, digital decoding, frame
synchronization, conversion between parallel and serial, external synchronization, audio
embedding and all circuits. No extra circuit cards are needed for VAM6800S. Owing to the

VAM6800 A/D Conversion and Audio Embedder - 5 -

low power dissipation, 6800N series frame can house up to 10 pieces of VAM6800 cards.

 Application in Multi-Standard

The VAM6800 can work in both 525 and 625 standards, and auto sensing on standards can
be achieved.

 Advance Decoding

High performance is secured by adopting 12-bit decoding. The full digital processing in
signal and luminance decoding ensures the precision of decoding, and thus no more
readjustments are needed, and system can work in high reliability for long hours. In the
meantime, digital decoding allows to adopt 5-line adaptive comb filter, thus effects on
separating chrominance and luminance of analog composite signal can be secured.

 Advanced Built-In Technology

The VAM6800 adopts 4X oversampling and built-in filter to guarantee better frequency
response, high signal noise ratio and low distortion.

 Frame Synchronizer

The built-in frame synchronizer of VAM6800 can solve the synchronizing and timing issues
of the system, and can provide frame freeze as well.

 Fully Functioned Processing Amplifier

The VAM6800 provides fully functioned processing amplifier to achieve the adjustment on
luminance level, black level, chrominance lev el an d Hue.

 SETUP Control

Working in the 525 standard, the VAM6800 can control SETUP.

 Synchronization

The VAM6800S can set the H-phase and V-phase.

FCC Caution:

Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.

This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference that may cause
undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
