Rob Glidden posts that a draft of the open media stack video specification is now available for comment. The specification defines a video decoder and associated bitstream syntax for decoding and playing video streams. From the specification:
The OMS video compression specification is based on legacy royalty-free technology and avoids the recently patented technology.
While this approach sacrifices the performance gains of recently patented techniques, the OMS video compression specification includes innovations of its own that at least partially compensate for these losses.
In addition, the OMS video compression specification takes advantage of contemporary semiconductor technology both to avoid the patented technology that was directed toward specific implementations, and to allow more sophisticated processing.
Where appropriate, patenting the innovations associated with the OMS video compression specification will provide a defensive portfolio of IPR to help maintain OMS as a mainstream royalty-free compression solution.
