The TLX Project – a Successor to SMPTE Time Code?

SMPTE Time and Control Code, to give it its full title, was initially developed in 1969.  It is now represented by three parts of the ST 12 Standard, and has been updated and enhanced many times.  The latest, and almost certainly the last, update was ST 12-3, published in 2016, offers limited support for higher frame rates.

ST 12 is probably the most used of all SMPTE standards.  It has proved flexible and durable, but the update process has become increasingly complex and cumbersome, and it is unlikely that further backward-compatible  updates will be possible.  It is still a viable standard, and will continue to serve for many years to come, but the time has come to develop a successor – one that addresses the shortcomings of ST 12 and is more suited to today’s environment.

Various projects within SMPTE failed to achieve consensus because of competing philosophies, and a “boil the ocean” approach.  The TLX (Time Label eXtensible) Project set a specified set of objectives, including the requirement for an extension mechanism to address future requirements.  This presentation will include a brief history, the objectives of the TLX Project, and a progress report.
