Sarnoff develops new test patterns for digital TV equipment

Steven Kim

Around these parts, "Joe Kane" is pretty much synonymous with "test patterns." The latest round of DVE has finally completed its winding journey to the land of HD DVD and Blu-ray, and just in time, too. A real grand-daddy of TV, Sarnoff Corp., will be showing off some new digital test patterns at the National Association of Broadcasters (NAB) show next week. If you've never heard of Sarnoff, look into David Sarnoff and Philo Farnsworth for a fascinating bit of TV history. The tried and true test patterns are useful, but show their analog roots with things like overscan, for example. These new test patterns are constructed for today's digital signal chain and take things like bit depth and format conversion into consideration. Don't put that new copy of DVE in the shredder just yet, though -- this test material is aimed at broadcasters. Rest easy with your DVE adjustments, at least for now.
