The OBE blog

After a huge amount of work and testing OBE Realtime 1.0 has been released today. This release is in use worldwide for a variety of different contribution and distribution services. It's worth pointing out this release is designed for general purpose use - this is to aid people testing OBE out on hardware that they already have as opposed to the recommended hardware. Therefore this release won't maximise CPU and quality on the most recent hardware. Currently the D100 is in QA and when the product ships code optimising for the most recent hardware will be released.

We will be having our annual IBC Open Source meetup on Saturday 14th, at the UK Hospitality Area 4.A61a in Hall 4 starting from 1800. Drink and snacks will be provided. There is no need to RSVP and feel free to pass this message on. (Note this is a different venue to last year)

Introduction

From time to time we work on other things beyond DVB broadcast encoding where Open Source can be used to transform closed broadcast workflows. The file delivery specification from the Digital Production Partnership (DPP) is one such area. However, the AVC-Intra codec used in DPP is effectively a proprietary codec with implementation in the real world being more complex than the SMPTE RP2027 that AS-11 recommends and in a number of areas implemented incorrectly. However, we have now successfully reverse engineered AVC-Intra from available samples which allows a fully open source DPP creation workflow. Leveraging existing Open Source projects for manipulation and creation of mxf files, a fully compliant DPP file can be delivered to UK broadcasters. Tests at interoperability events have showed that this implementation has no interoperability issues.
