SMPTE(

R), the organization whose standards work has supported a century of technological advances in entertainment technology, today published two documents, the Time Code Summit Report and the Material eXchange Format (MXF) Time Code Study Report. Both reports offer valuable insights into how the SMPTE Time Code(TM) standard (ST 12-1 Time and Control Code) can evolve to serve as a more useful tool in media production.

"SMPTE Time Code is used extensively throughout production and postproduction. With the evolution of media technology since its introduction in 1975, it is showing its age in some areas," said SMPTE Director of Engineering and Standards Howard Lukk. "We are exploring ways to improve Time Code. The results of the Time Code Summit Report provide a better understanding of the drawbacks in its current use, in and beyond the conventional audio/video community, and of the direction we need to take in developing a new standard. At the same time, we're using the MXF Time Code Report to clarify Time Code in MXF and how facilities can work with it more efficiently."

The Time Code Summit Report presents the methodology and findings of surveys performed at the Time Code Summit, a series of focus groups held in London, New York, and Los Angeles. The report summarizes user requirements that must be addressed by any new Time Code standard, particularly the proposed Time Labels standard to address the radical changes brought about by the industry's integration of Internet Protocol (IP), the push to higher and variable frame rates, and other factors testing the limits of the existing Time Code standard. The report also includes an explanation of the study effort, the survey questions asked and answers provided, and the dialogue that occurred at each summit.

The MXF Time Code Study Report focuses on the current usage of Time Code within the MXF file format. Since the creation of MXF in 2004, Time Code has been stored within MXF files in many ways -- sometimes as metadata, and sometimes as actual Time Code values from a tape or stream. This report is the result of two years spent investigating current MXF Time Code practices and documenting findings. The report considers applications that need to write MXF files with Time Code and applications that need to read MXF files containing Time Code. It examines the three core requirements highlighted by the study group: MXF should be able to store multiple Time Code values per frame, and they should all be identical; store multiple Time Code values per frame, though they may be from different sources and have different values; and include the appropriate Time Code in audio-only files.
