Video waveform monitor uses Dolby technology

Dolby E is a digital audio technology optimised for the distribution of surround and multi-channel audio through digital two-channel post production and broadcasting infrastructures.

Dolby Laboratories has confirmed that the PT0760M can now handle Dolby E decoding, either from embedded audio within the HD/SD video or through separate AES inputs via Dolby's 552 OEM decoder module.

The PT0760M can also provide analogue or AES audio outputs with integral level control.

This allows the PT0760M to provide an integrated solution for managing and monitoring Dolby Digital 5.1 coded audio signals.

The PT0760M is effectively four HD/SD waveform monitors in one box.

This unit is aimed at outside broadcast vehicles, production studios, master control rooms and camera control units.

Its feature set includes four separate auto-sensing HD/SD inputs that allow simultaneous display of four individual waveform monitors showing G, R, B, Y, Cb, Cr and luminance.

A vectorscope is also included.

The PT0760M has a DVI output that enables the user to view multiple screens on a single external display.

The images can comprise of all four waveform monitors and the selected audio metering.

DK has provided 11 user presets, user-definable Gamut error settings and 10 user-definable soft keys for fast set-up.

Horizontal and vertical zoom is achieved via an inbuilt jogwheel and the unit also has an internal memory.

The PTO760M incorporates DK's MSD range of audio software, which feature the company's Jellyfish and Starfish displays for stereo and surround sound monitoring.

This combination of video and audio metering includes HD/SD audio de-embedding, surround sound metering, peak programme level measurements of up to 32 audio channels and seven selectable scales to conform to in-house standards.

Users choosing this combined option also benefit from DK's ITU 1770 loudness meter, which uses an approved ITU algorithm - an extension of Leq (RLB) - covering stereo and monophonic audio signals.
