Sencore Improves on MP500 HDMI Analyzer

Sencore announced several enhancements to its MP500 MediaPro Handheld Generator and HDMI Analyzer.

Sencore announced several enhancements to its MP500 MediaPro Handheld Generator and HDMI Analyzer.

The Sencore MP500 MediaPro Cable Test feature makes it easy to identify elusive problem cables and devices in an HDMI system by testing HDMI distribution signal paths for TMDS bit errors, analyzing each line of an HDMI cable and sequencing through multiple signal resolutions using a pseudorandom noise test signal.

When using pseudorandom noise from any Sencore VideoPro Generator (VP401 and above) through the HDMI distribution path to the MP500 HDMI input port, AV integrators can analyze and report the number of TMDS bit errors at points along the distribution system and determine if the source, cable, display, or repeater is causing the problem. Different resolutions can be sourced from the generator to analyze bit errors by format.

"While on a large job, where the equipment rack was about 50 feet from the projector, our installer could not determine why there was no picture. He had already swapped the cable once and the set top box," said Dennis Erskine of the Erskine Group, in a statement. "When the senior installer arrived with his MP500 he quickly determined that the powered repeater (HDMI booster) was defective and all other components were fine. This saved us hours of troubleshooting time and we were able to complete the job on time,"

Sencore officials said the MP500's HDMI audio generator has been expanded to include audio test signals needed to test multichannel HDMI audio systems, and provides the test patterns required for room acoustic measurement and analysis, including pink noise, impulse, polarity, sine waves and more. The test signals can be selected and applied to a single channel, all channels or sequenced to selected channels within a multichannel HDMI signal. The MP500 currently sources 5.1 and 6.1 multi-channel audio signals via HDMI.

The MP500 also offers numerous unique static video patterns and a motion Zone Plate pattern for detecting video artifacts during high-end video installations. Custom test patterns (bitmaps) can be imported and a new set of ISF-approved test patterns are now available for purchase.

A variety of troubleshooting features are included to help with HDMI interface-related problems. EDID and HDCP tests are provided to test an HDTV or a repeater's input port. A CEC check can be initiated to view the CEC devices in an HDMI system. The MP500 also includes an HDMI input port for emulating an HDMI sink (display) device. It enables testing of the audio and video of an HDMI source device, including video content protected with HDCP. The HDMI input is provisioned with an EDID to test a source's response.
