The article focuses on study related to generation on video and audio format's timing by using precision time protocol (PTP). Topics discussed include generation of video, audio and time codes from PTP, delays incurred by network communication and requirement of deep-nanosecond alignment for synchronous switching of serial digital video along with the U.S. broadcasting industry to achieve genlocking.

The article presents a technical paper providing case studies on codec selection, time code and subtitle carriage, and audio channels of an audiovisual (AV) file. It mentions several layers of an AV program including code information, subtitles and aspect ratio in production or archive. It provides schematic diagram of AV file which consists of ancillary essence layer, code headed layer and wrapper layer. It also discusses how to manage several interoperability issues in real-life workflows."

The article focuses on the analog closed captioning was mandated in 1996 after the Telecommunications Act and carried in lines 21 and 284 of the NTSC broadcast signal. It mentions that captions appear in an area of the picture called the vertical blanking interval (VBI) which was out of the visible range of televisions. It adds that it shares with V-Chip television rating information, macrovision, vertical interval timecode (VITC) and copy generation management system (CGMS) copy-protection.

The article offers information on the goal of the Society of Motion Picture & Television Engineers (SMPTE) Time Labeling and Synchronization (33TS) technology committee (TC) to develop forward-looking standards and to recognize the convergence of information technology and broadcast domains. Tthe TC will provide flexibility to enable SMPTE ST-12 timecode applications and will move on from the use of analog waveforms. The TC comprises time labeling, snychronization, and ad-hoc working groups.

The article offers information on the standards activities of the Society of Motion Picture and Television Engineers (SMPTE) in 2009. It states that SMPTE has released more than 30 new standards documents and conducted four very successful block meetings. Furthermore, SMPTE also published two Task Force Reports on three dimensional (3D) to the Home and on Timing and Synchronization and has created a Working Group headed by Ted Szypulski of ESPN to develop standards for the SMPTE 3D Home Master.

The article provides historicals briefs from the journal's past articles. Some of the articles published include an article on misunderstanding of the SMPTE time code published in the January 1983 issue and the practical problems in recording and reproduction of music for motion pictures by David Mendoza published in the January 1933 issue.
