Tektronix New Product Highlights at NAB

WFM800 and WVR8000
To produce 3D content, a range of new 3D production equipment is required to combine images from the two cameras, representing the Left Eye and Right Eye. One of the key monitoring elements is to ensure that the two cameras are well balanced and matched to create good quality 3D effects without causing discomfort for viewers. Tektronix has introduced several new displays for 3D production work that assist production teams who are determining the differences between the Left Eye and Right Eye images.
The 3D Difference Map Display can be used to effectively detect disparity between the Left Eye and the Right Eye images during camera setup (alignment) of 3D production or 3D post production. The Anaglyph Display allows users to identify parallax (3D depth) of various objects within the 3D video image. The Checkerboard Display helps the user (such as a stereographer or a colourist) identify any differences in luminance levels (brightness), focus, and various colour characteristics between the Left Eye and the Right Eye images. For monitoring of depth of various objects within a 3D image, a Disparity Grid can be overlaid over various 3D picture displays. A Disparity Cursor is also available for precise measurement of the disparity between the left eye and right eye of an object within the image.
The new 3D video monitoring capabilities will be available as standard with all new WFM8300 and WVR8300 instruments. These new capabilities will also be available on the WFM8200 and the WVR8200 instruments with the purchase of Option 3D. Existing WFM8300 and WVR8300 instruments as well as WFM8200 and WVR8200 instruments with Option 3D can also be upgraded with the new features free of charge through the new firmware upgrade available on

Sentry 5.0
Tektronix brings significant new capabilities to its award-winning Sentry® digital content monitor. The Sentry 5.0 release enables Sentry to perform in-depth monitoring of video streams at full line rate -- 1 Gbps per unit. No other video monitoring solution on the market can match Sentry’s speed and monitoring depth. This performance enables video service providers to monitor hundreds of video streams per unit, which reduce the number of Sentrys to comprehensively monitor a large multi-channel lineup.
Sentry 5.0 introduces eMOS, or Perceptual Video Quality, which helps service providers tackle content errors where the QoE score is good but the program suffers artifacts due to over-compression which is common in motion intensive programs like sports. In addition, the new release includes GOP length statistics, RTP support and new reason codes that help service providers quickly understand the source of an issue.
VQS1000
Tektronix has further enhanced its family of products with critical audio loudness capability. Tektronix adds Audio to the VQS1000 Video Quality Analysis Software. Building upon the audio loudness measurement capabilities available across its product portfolio such as Sentry Digital Content Monitor, VoD Asset Verification tool (Cerify), and in Waveform Monitors and Rasterizers for broadcasters, the new software upgrade adheres to the ATSC A/85 Recommendation and ITU-R BS.1770-1/1771 specifications. The upgrade includes capabilities such as an LKFS Audio Loudness Meter, an Audio Loudness Session Display, and trending and alarm reporting information. The VQS1000 is ideal for network analysis tool troubleshooting QoE problems and tracing them back to the underlying QoS root cause.

Picture Quality Analyzer Software
Next generation compression algorithms are enabling broadcasters to scale video from high-end plasmas to mobile handsets, while increasing the complexity of CODEC designs for manufacturers. As these new compression technologies are deployed to distribution and archive, the importance of chrominance measurements and 10 bit measurement increases.
To respond to these needs, Tektronix now offers the PQASW, a software version of its premier picture quality measurement instrument, the PQA600. The PQASW addresses the need to scale Picture Quality measurements in terms of the speed and portability of the analysis platform, the Picture Quality scores, and the analysis depth. For advanced analysis, the Advanced Option (Option ADV) offers designers a 10 bit measurement execution for evaluating emerging 10 bit encoding algorithm, and a colour PSNR measurement with Vector Display. For evaluation and trials of transcoders with an IP interface, the PQASW includes an embedded reference decoder and IP interface (with option IP).
