One Step Closer to Broad Adoption of MPEG-DASH: DASH264 Implementation Guidelines Released Today


The DASH file specification is on track to fulfill its promise to unify the adaptive streaming world. We have seen a lot of interest from partners and customers in our DASH implementation guide and IBC demonstration. DASH is not only a basis for DECE/UV, but has also found broad industry support (as Petr outlined in his recent post), even from the big players like Adobe and Microsoft. I participated in a recent panel (recording here) with other industry experts from very different areas to explain our interest in DASH and answer questions from the audience.


Industry-wide collaboration in the creation of the DASH standard is a large part of its success; another factor is the support of technical features that, as years of experience with adaptive streaming have shown, are crucial components of a mature solution. Examples include late binding of audio, flexible manifest creation with templates and common encryption. The latter is of particular interest for us as it aligns with our multi DRM and standards-based security strategy.

I have been fortunate to help guide the discussion on how the common encryption specification is best used to allow multiple DRMs to be applied to the same file while being truly interoperable. This entailed an interpretation of the specification, understanding the best practices and relevant use cases, and explaining them for others to implement. We did this as a group within the DASH Industry Forum (IF), a collaboration of 50+ members  with the aim to publish general interoperability and deployment guidelines and to facilitate interop tests.

As our first outcome, we have released a draft of those DASH IF guidelines as: Guidelines for Implementation: DASH264 Interoperability Points. They show the direction the DASH Industry Forum is taking, and explain DASH concepts in several informative sections. We are encouraging comments on these guidelines, until March 15th, 2013, while we move towards a final version that is scheduled to be published on March 31st, 2013. The main contact information is on the download page and I am also happy to directly clarify or discuss any DRM related components. Please feel free to leave a comment!
