Tektronix' WFM/WVR5250 waveform monitors and rasterisers enable monitoring of video and audio loudness output of set-top boxes and Blu-ray players

Tektronix has added to its product line of broadcast video test, monitoring and analysis instruments, waveform monitors and rasterisers with the WFM and WVR5250 models, the only products in their respective classes to offer HDMI-HDCP inputs that enable broadcasters, operators and equipment manufacturers to directly monitor the quality of the video and audio output of set-top boxes (STBs) and Blu-ray. WFM/WVR5250 are compact and portable video and audio test tools for acquisition, post production and compliance monitoring.

Before the WFM/WVR5250 and its HDMI-HDCP inputs, there was no way to monitor the video signal quality output from STBs, Blu-ray players and other consumer devices with HDMI outputs. The majority of video and audio content provided through the HDMI connector on consumer devices such as STBs and Blu-ray players is encrypted, using HDCP for copy protection and only certified HDCP compliant devices can provide the necessary decoding. The WFM/WVR5250 is HDCP compliant allowing users to have direct access to the data they need to assess the quality of the signal output by any consumer device that uses HDMI interfaces. This is essential for users who are trying to objectively measure the customer Quality of Experience and compliance to broadcast and regulatory standards as seen by viewers.

In addition to checking the output of their STBs, broadcasters, operators and equipment manufacturers can use the HDMI-HDCP connectivity of the WFM/WVR5250 to test new STB firmware releases in the lab and diagnose interoperability issues. This eliminates the need for dedicated HDMI protocol analysers. Operators can also conduct audio loudness “quick checks” which is important for complying with the EBU – Recommendation R 128 and for ensuring audio quality during live sports events and other programming.
