Tektronix Showcases New Solutions for Improving Video and Audio Quality at Cable-Tec Expo 2011

Solutions for Monitoring Critical Points in Adaptive Streaming and Identifying Loud Commercials Demonstrated at Cable Industry's Biggest Tradeshow (November 08, 2011)

BEAVERTON, OR -- (Marketwire) -- 11/08/11 -- Tektronix, the market leader in broadcast video test, monitoring and analysis solutions, will unveil new and enhanced products for video, audio and content quality at its booth (#326) at Cable Tec-Expo, November 15-17 in Atlanta. Highlights for this year's show include the introduction of the new MTS4000 MPEG analyzer, a new version of the company's Cerify® software and demonstrations of the latest capabilities of the award-winning Sentry® digital content monitor, including how it can be used to ensure the quality of adaptive streaming services.

Monitoring Adaptive Streaming Services
Cable television operators are increasingly using adaptive streaming to deliver video services to mobile devices and PCs. These new services are critical to competing against other video service providers, but pose unique quality challenges. In particular, operators must transcode their programming from MPEG-2 into the more bandwidth-efficient H.264 codec, a step which can introduce errors that impact video and audio quality. At this critical point, Sentry can identify these errors before the H.264 streams are fragmented and encrypted, which is vital as these errors cannot be detected after encryption. The early detection and diagnosis of these errors enables operators to fix the cause and ensure an optimal quality of experience (QoE) for their subscribers.

Complying with the CALM Act
The company will also demonstrate its new Sentry Assure, the latest addition to the Sentry line which is optimized to help cable operators comply with the Commercial Advertising Loudness Mitigation (CALM) Act which requires that ads be no louder than the programs they accompany. Sentry Assure is designed specifically for identifying loud commercials in the multi-channel cable environment. It combines the ability to simultaneously monitor hundreds of channels in real-time with loudness detection capabilities and post-splice ad insertion monitoring, which makes Sentry Assure an ideal solution for cable operators' CALM Act needs.

Identifying Bad Ad Insertions
Tektronix will also demonstrate how Sentry Assure's post-splice monitoring capability identifies when local ads are not inserted correctly, enabling operators to diagnose and repair the issue, eliminating revenue loss from ads failing to air properly.

Complying with Closed Captioning Requirements
Another demonstration will show how operators can comply with government regulations for closed captioning using Sentry Assure's support for the SCTE-608, SCTE-708 and SCTE-20 specifications.

New MTS4000 MPEG Analyzer for IP Video Quality and 10G Network Monitoring
Multi-screen video delivery of SD and HD content has driven the investment in 10G infrastructure. The new MTS4000 MPEG Analyzer is ideal for the analysis and troubleshooting of audio/video and transport problems in 10G networks for fault isolation and root cause analysis. Targeting a range of design, validation and test, field diagnostics and troubleshooting applications, the new MTS4000 offers unparalleled analysis capabilities for examining the video and audio quality of IP and RF video services.

The low entry price and modular nature of the MTS4000 offers a wide range of connectivity and software analysis options that allow complete customization to meet all application needs and budgets. Network interface options include 10G IP, ATSC 8-VSB, QAM-B, DVB-S2, and a Quad port ASI interface. Cross-layer and cross-domain analysis of the video and audio quality is possible through an extensive software suite that includes real-time video and audio QoE analysis, picture quality analysis (based on the human vision model), and advanced Elementary Stream analysis including H.264 intra profile and SVC support.

Cerify® Software Version 7.3 Targets Audio
The new version 7.3 of Cerify SW (a software solution for file-based content verification) supports the latest audio loudness measurement. It supports cross-track audio loudness testing for implementations such as HD MXF, where channels in a group are spread across many tracks. New standards supported include algorithms recommended in the ITU-R BS.1770-2 specification, and the Peak Program Meter (PPM) audio ballistics measurement in the IEC-60268-10 standard.
