Dear Ed,

​

I'm sorry that my schedule doesn't allow me to to attend the OMF

developers' conference in New Orleans. However, it may be appropriate to

offer a few words at this time.

​

BWF Audio Files.

There are many competent file formats that can be used to store audio data.

When deciding on a standard recently, the EBU (the European Broadcast

Union) adapted a simple and widely available file format.

​

The EBU Broadcast Wave Format (BWF) comprises a conventional RIFF Wave file

with an additional header chunk in each file to carry a set of source

identification and timecode information.  These extra parameters provide

the hooks necessary to pass sound recording through the many stages of

complex production and post production jobs without overburdening simpler

applications. Importantly, 'timecode' information is incremented at audio

sample rate to give a very high resolution time reference that is

independent of, but which can be used with, any conventional timecode or

film/TV picture frame rate.  This promises smoother interchange both

internationally and cross-media.

​

AES

When the AES Standards Working Group on Audio File Exchange also considered

the requirements of a sound file to form part of a wider - and scaleable -

interchange scheme, a similar set of features was required.  The AES

Working Group is expected to adopt and standardise the EBU BWF audio file

format.

​

The AES standard will use these audio files both standalone and within two

types of Project Structure (organisational structures that will facilitate

edited material to be passed from one piece of equipment to another).  A

Simple Project Structure will comprise a fairly conventional Edit Decision

List (EDL).  The Object Oriented Project Structure will be capable of

conveying more processing information; an audio-specific subset of OMF is

proposed for this role.

​

Accordingly, I am happy that the OMF format will be able to use EBU BWF

files.  This provides for a degree of synergy between different

applications and stages of production that I think will be beneficial to

the industry at large.

​

Detailed information on the BWF is available from the EBU web site at:

​

Sample files are available from Swedish Radio at:

​

​

I wish you all a great time in the (comparatively) warm South.

Dear Ed,

​

This relates to our discussions before the holiday.

​

It is apparent that, even with an audio-only subset of the OMF scheme, the

AES group is having some difficulty discussing the subject with the

experience and authority necessary for its practical implementation as a

general interchange standard.

​

To keep this topic moving forwards, I wonder if it would be possible to

form a number of experienced people, perhaps from within the OMF Developers

group,into an AES Task Group.  The role of this Task Group would be to

provide advice to the SC-06-01 AES Working Group on practical matters

related to the implementation of OMF in audio systems.

​

You have very kindly offered to explore the possibility.  Could I ask you

to consider this during the OMF Developers Conference next week and let me

know you thoughts as soon as possible?

​

Many thanks

​

AESSC has become a B-member of  the  DVD  Forum,  the  successor  to  the  DVD

Consortium.   As  a  B-member,  we  can participate in the working groups, but

without an official vote.  I have listed  the  programs  of  the  two  working

groups that are related to audio.

​

The WG10 group is being chaired by Steve Sohma, one of our vice-chairs  and  a

member  of  our Steering Committee.  He has scheduled the next meeting of WG10

for 1998-02-05 14:00 at Pioneer headquarters in Tokyo.

​

I will be preparing the full Forum prospectus for  downloading  from  our  FTP

site.   Thus  far, we have not received machine-readable copy, so it will take

time.  Rather than delay any more, I have included only the  programs  of  the

two  groups  in  this  memo.   We  need  to consider how to participate in the

proceedings.

Dear Mr Queen,

​

Thank you for your email. You have addressed it to Mr Verrier at Digigram

 verrier@digigram.com), who have forwarded it to me.

Digigram is very much interested in some participation with regards to the

DVD  standards proceedings, and definitely we would appreciate to be

informed about the progress. It will be very difficult to arrange my

schedule on such a short notice ( for the Tokyo meeting), however if you

would be so kind and let me know the schedules for the next meetings, I

would do my best to attend at least some of them.

​

In the mean time please be so kind and replace Mr Verriers name and email

address with mine as he is now involved in another project. If it is

possible, please add Mr Patrick Tardy ( tardy@digigram.com) - Market

Research to the emailing list.

​

Best regards,

​

Wlodek Sielski
