BS EN 62122 discusses methods of measurement for consumer-use digital VTRs with a focus on electronic and mechanical performances of digital VTRs.
BS EN 62122 specifies the basic methods of measurement for evaluating the electronic and mechanical performances of consumer-use digital VTRs.
There are two objectives for the proposed methods of measurement. One is to check the interchangeability and characteristics of the equipment under test which are indispensable to manufacturers, and the other is to evaluate the quality of image and sound, which concerns the customer. The latter is a priority for consumer satisfaction.
BS EN 62122 on electronic and mechanical performances is useful for:
A videotape recording and playback machine. VTR may refer to consumer MiniDV and DV recorders or to professional machines such as Betacam, DVCPRO and DVCAM. Digital VTR 6,35 mm DV format and 12,65 mm D-VHS format have now been brought on the market.
Consumer-use digital VTR is a consumer-use videotape recorder using digital recording technology, 6,35 mm to 12,65 mm width videotape and bandwidth compression technology for the image signal.
BS EN 62122 provides you with guidance on measuring conditions, measuring instruments, Methods of measurement for mechanical characteristics, video characteristics (analogue input/output), composite signal decoding characteristics (luminance and chrominance separation), and audio characteristics (analogue input/output), etc.
The measuring methods and conditions provided by BS EN 62122 assist you in improving the electronic and mechanical performance of consumer-use digital VTR.
With obedience and compliance to BS EN 62122, you can enhance Consumer-use digital VTR’s effectiveness and efficacy and manufacture a standardized high-quality product.
