01. What is OMS and OMS Video?
A: "OMS" is an activity of Sun's Open Media Commons initiative to provide a free (open-source and royalty-free) complete media solution, including video, audio, transport, control, and content security -- an "Open Media Stack".
The Open Media Stack (OMS) Video Specification defines a video decoder and the associated bitstream syntax. It is intended for delivery, storage and playback of video streams.

02. Why have you started from h.261?
A: H.261 was finalized in 1989, outside the (17-year) patent window. Key tool strategies and prior art were already established in that era. |
| |
03.What do you plan to use for an audio format?
A: We expect to include Xiph Vorbis. |
| |
04. Why not just use a profile of h.264?
A: Sun was a part of the 2003 IMTC alliance of the 20+ companies that urged publicly a royalty-free baseline for h.264, which was ultimately not adopted |
| |
05. Are you planning an open source implementation of OMS Video? Wavelet mode? A file format?
A: Yes, maybe, yes |
| |
06. Would you consider contributing OMS Video for standardizing by ITU, MPEG or other group?
A: Yes, if there is a robust royalty-free IPR process (mutual non-asserts, etc) in place that would assure that the standardized result remains royalty-free.

07. How do you view other open source / RF codecs like Vorbis, Theora, and Dirac?
A: Collaborators in a common community. We believe we bring particular competencies from Open Media Commons and we seek to bring an updated royalty-free variant from the h.2.6x lineage to the open source / royalty-free community. |
