The TLX Project – a Successor to SMPTE Time Code?

This presentation will include a brief history, the objectives of the TLX Project, and a progress report.

Description

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.
