Video test gear gets HDMI v1.1 support

Video test vendor Quantum Data will soon be rolling out an upgrade to its 802-series of HDMI (high-definition multi-media interface) generators and analyzers. The upgrade kits, available in January 2005, will let existing users of Quantum's gear enhance their 802R/BT-HDMI instruments in the field.

Quantum Data says its test instrumentation will be among the first to be certified by an HDMI ATC (Authorized Testing Center) for HDMI v1.1-level work. The company also claims its 802-series is now a reference standard for HDMI/CEA application-layer development and production testing.

The 802BT multi-media video signal generator, for example, can test CRTs, flat panels, projectors, and low-definition TVs, as well as HDTVs (high-definition televisions). The generator and analyzer products in the series can emulate both source and sink devices, so manufacturers of HDTVs, set-top boxes, players, and repeaters can know that their HDMI ports are well-integrated and functioning properly.

The 802BT is optimal for digital TV, and digital and analog displays; it permits production and engineering users to create complex test images. A PCMCIA slot makes it easy to copy one generator to another using plug-in PC Card memory cards.

The upgrade increases source performance from 81MHz to 165MHz, so that both single-link DVI and HDMI sinks can now be tested to the maximum rate using one instrument. Sink performance is also increased from 81MHz to 150MHz.

HDCP 1.1 improvements also include the ability to test repeaters. The source's internal sinewave generator now supports 8-channel LPCM with sampling rates up to 192kHz.

What's more, functional tests complement transport-layer tests conducted in compliance labs. These usually require more expensive equipment. For example, Quantum notes that OEM Silicon Image currently uses 802-Series instruments in its regional pre-testing centers where its customers test and debug pre-production products in preparation for more costly final HDMI ATC testing. The 802-Series instruments are also used for conducting source E-EDID literacy tests.
