The EBU Strategic Programme on the harmonisation and interoperability in file-based HDTV production (SP-HIPS) , has updated the EBU Recommendation on how to use timecode in Material Exchange Format (MXF) files. It is the first public deliverable from the Group.
| Most important
MXF is the most important standard for file exchange between professional media organisations. To improve the interoperability of MXF products, end of 2009 the EBU HIPS-MXF Group was set up, led by Mr Christoph Nufer (IRT). Mr Nufer’s team started with updating the existing EBU R 122 “Material Exchange Format Timecode Implementation” recommendation, which was created in 2007. The new documentincludes, amongst others, information on handling 50/60 Hz timecode and timecode with new HDTV essence types. More to follow According to EBU Programme Manager Dr Hans Hoffmann, the MXF Group’s work addresses a key aspect of file-based HTV production: “This is one of the ‘lego blocks’ people need to get right, to be able to work with media files flawlessly. Other elements EBU work is focussing on includes acquisition [camera] metadata, new HDTV studio codecs, 1080p/50 and 3G SDI.” |
The work of the HIPS-MXF Group now continues with specifying the recommended ways of carrying subtitling in MXF. The draft for this EBU Recommendation is far finished, and already available to participants in the MXF Group for review.
