SMPTE 2018 Annual Technical Conference & Exhibition
Dear readers and film buffs! RAD TIMES is back with another article on SMPTE. With a new article comes a better understanding , penetration and information! Happy reading and do tell us how it was!
In the previous article we discussed about the SMPTE & it's education. In this article, you will be about the understanding of SMPTE.
A film set in action!
SMPTE was founded in 1916 to address the lack of standards in the emerging movie industry where there was no agreement on film width, image format, perforations, etc., and only a small chance that a specific film could be displayed on a given projector. Today, SMPTE maintains a multitude of standards for film gauges from 8mm to 70mm, covering all these parameters plus many others such as edge coding, analog, and digital sound. SMPTE standards also include lens mounts, spools, film processing and storage, cinema sound, and a plethora of other areas needed to ensure interoperability in a complex, global industry. The use of film is declining as it is supplanted by electronic imagery in both acquisition and display. However, SMPTE film standards continue to form the foundation for the industry, and a level of performance that is the benchmark for digital cinema.
WORKING OF SMPTE
There are 800-1000 different fields on which SMPTE works, for example, few of them are:
The term encapsulation refers to the process of taking something complex and making it simple. Encapsulation takes information from a higher layer and adds a header to it, treating the higher layer information as data. It is often said, “One layer’s header is another layer’s data.” For example, as the data moves down the stack, application layer data is encapsulated in a layer 4 TCP segment. That TCP segment is encapsulated in a Layer 3 IP packet. That IP packet is encapsulated in a Layer 2 Ethernet frame. The frame is then converted into bits at Layer 1 and sent across the local network. Data, segments, packets, frames, and bits are examples of Protocol Data Units (PDUs).
Data encapsulation requires at least the reading function (get) which could be used by the maintenance tool to enable access to internal data in the event of operating issues.

It is the process to be able to use exiting audio formats by bringing them under one cover so that different needs ofthe Speaker Biometrics community are met without having to resort to using proprietary formats. Considering the various scenarios for audio interchange, three different goals are most prevalent.
In order to make a smooth ride for video to screens other than the TV, that content may need to be re-packaged. That’s encapsulation. This is where the language of it gets almost visceral, in terms of how it works. Here’s another example, from a recent batch of notes: “What you do is, you strip off the IP header, de-jitter the stream, then restore it to MPEG format.”

Apart from these SMPTE also provides the following: SMPTE is an internationally recognized standards development body. As such we abide by the ANSI and ISO due process for initiating, approving, revising and removing standards. For nearly 100 years, SMPTE has been the leader in standards for the motion imaging industry, facilitating interoperability and therefore business.
Published documents include standards, recommended practices and engineering guidelines, all of which integrate to describe a particular process.
SMPTE Engineering Guidelines
Engineering Guideline- Supplemental Information for 170 M and Background on the Development of NTSC colour Standards.

Annotated Glossary of Essential Terms for Electronic Production
SMPTE Standards :
SMPTE is the leading standards development body for motion-imaging standards. Individuals and organizations from around the world come to SMPTE to develop standards that are adopted by manufacturers, broadcasters, and studios.
For Video Recording -- 2 in 1 Magnetic Recording Tape
For Television Analog Recording -- Frequency Response and Operating Level of Recorders and Reproducers -- Audio 1 Record on 2 in Tape Operating at 15 and 7.5 in/s.
For Television Analog Recording -- 2 in Magnetic Tape for Quadruplex Recording Speed.
SMPTE & It's Technical Committees
The general scope of all Technology Committees is to develop SMPTE Engineering Documents; to Review existing documents to ensure that they are current with established engineering practices and are compatible with international engineering documents, where possible; to recommend and develop test specifications, methods, and materials; and to prepare tutorial material on engineering subjects for publication in the SMPTE Journal or for other means of dissemination benefiting the Society and the industry.
Content Creation Committees
The application of the General Scope as it applies to electronic capture, generation, editing, mastering, archiving, and reproduction of image, audio, subtitles, captions, and any other master elements required for distribution across multiple applications.
The application of the General Scope as it applies to the application of mastered essence to theatrical film distribution, including, media and component creation, marking, laboratory methods, reproduction, packaging, projection, and related topics. Additionally film capture, editing and recording.
