Audio Displays (Optional

Capability)

Available in the WVR7000 Series are a

range of audio options that can add

comprehensive audio monitoring capabili-

ties for analog audio and digital audio.

Level bars display, or both bars and a

Lissajous display, can be selected to

provide monitoring for digital audio

formats, embedded or externally input up

to four stereo pairs, or for up to two sets

of six balanced analog inputs. The level

meters offer selectable meter ballistics

and scaling. Analog audio scales can be

set to dBu, DIN, Nordic, VU or IEEE PPM.

Digital audio scales are available for dBFS

and can be user configurable. These

instruments have a set of two program-

mable levels designed to optimize detec-

tion of out-of-range conditions in analog

signals, or in digital signals derived from

analog sources. The over and silence

settings augment digital clip and mute

detection by letting users select levels to

represent these conditions in the analog

audio domain.

In addition to audio displays, a full range

of audio error conditions can be selected

for monitoring, including AES unlock,

parity errors and checksum errors.

Status Displays

The WVR7000 Series offer a variety of

displays designed to show status at a

glance, in addition to the status bar

continually displayed at the bottom of the

screen.

A comprehensive overview of the video

content status is presented in the video

session screen. Offering a time-based

compilation of information, this screen is

ideal for presenting evidence of compli-

ance after content screening. Information

on input format and session time is

presented, along with statistics on Error

Detection and Handling (EDH)/Cyclic

Redundancy Check (CRC) errors and

gamut errors. Information is presented in

errored seconds, errored frames and

percentage of total frames - together

providing a unique quantitative insight to

content quality.

When one of the audio options is

installed, an audio session screen is avail-

able to confirm evidence of compliance.

This screen records the highest true peak,

as well as the number of mutes, clips,

overs and silences during the session time.

An alarm status screen can also be

displayed providing up-to-the-moment

information on the state of each condition

currently being monitored by the instrument.

To support unattended monitoring appli-

cations, as well as provide documentation

for service level agreements, the system

maintains a log of all monitored alarms,

time stamped with Vertical Interval Time

Code (VITC), Longitudinal Time Code

(LTC), Ancillary Time Code, and time of

day references.

A summary of audio errors is combined with

level bars and Lissajous, picture monitor

and vector.

Audio and video summary statistics

combined with a gamut display.
