A digital tape format developed by JVC based on the VHS tape transport. Most commonly used for HD delivery, it supports MPEG2 encoded video at rates up to 25Mb/s. There are currently 3 different types of DVHS tapes. D-Theater DVHS tapes are recorded with a special copy protection system for wide release of high definition content. Pro-HD DVHS offers the ability to record and playback in a password-protected mode for playback on Pro-HD DVHS equipment, giving content providers the ability to protect their material (this feature is often used for Digital Dailies). Pro-HD equipment will also playback D-Theater and Consumer DVHS tapes. Consumer DVHS offers recording and playback of non-copy-protected and off-the-air material and playback of D-Theater titles.
