OMWF is a Japanese industry consortium aiming at compatibility in MPEG-based multimedia applications.

The group, that includes various hardware and software vendors and content providers in Japan, has its offspring in the popularity in Japan of CD movies and Karaoke. Through cooperation with the Open MPEG Consortium in the USA, the OMWF cleared up details in the MCI standard, that impeded compatibility. The new specification, called the Video CD specification, allows Windows machines to play MPEG-1 video CDs, and allows Windows data and applications to be stored on the same CD along with the video contents.
