Harris Highlights Videotek Test and Measurement Enhancements
Company emphasizes audio stability, closed captioning compliance for terrestrial DTV
DENVER: Harris Broadcast
Communications is highlighting Videotek test and measurement enhancements
and new products at the IBC 2012 convention in Amsterdam.
The company has enhanced Dolby support to existing TVM waveform
monitors and VTM Series rasterizers with support for the Dolby Digital Plus
standard, and adding Cyclic Redundancy Check detection and alarming for Dolby-encoded
audio streams. “CRC monitoring eliminates unexpected audio dropouts and
enables a more stable and pleasurable viewing experience for the consumer,” it
said Dolby Digital Plus is an emerging standard that is part of terrestrial
HDTV specifications in several countries including France, Italy, Sweden,
Poland and the United Kingdom. China added Dolby Digital Plus to its Digital
Terrestrial Multimedia Broadcasting (DTMB) receiver specification, and Harris
said the standard is finding footing in India.
The enhancements are
compatible with existing TVM and VTM products. New firmware is available
for download (select Service and Support tab, click on Customer Portal).
Harris also has made
metadata enhancements to its CMN Series of Compact Monitors, which now supports
display of closed captions and subtitles along with video images in various global
formats, including World System Teletext, OP-47 and CEA-708. The CMN-91 is shown here.
Harris also is
featuring other recently introduced Videotek test and measurement reference
products. These include VSG-4CSD clock system driver and VSG-4MTG master timing
generator to establish house synchronization and router timing, suitable for mobile
production trucks and providing 3 Gb/s, IEEE-1588 and 2K support; the MSA Series
for confidence monitoring and signal compliance, to be used standalone or in
Harris DVB-T2 headend solutions; and the VSX-11-3G multi-format changeover
system, which performs automatic switching of 11 primary inputs to secondary
inputs for signal redundancy.
