NASA-STD-2818 (VER. 4.0), NASA TECHNICAL STANDARD: DIGITAL TELEVISION STANDARDS FOR NASA (10-JUN-2015)

NASA-STD-2818 (VER. 4.0), NASA TECHNICAL STANDARD: DIGITAL TELEVISION STANDARDS FOR NASA (10-JUN-2015)., The DTV system standards described in this document are associated with those industrial or professional systems used to produce full motion and full resolution digital video imagery that is suitable for critical closed circuit or broadcast use and which is normally distributed over wide bandwidth communications systems designed for the transmission of television. It is not the intention of the NEIG or of the Office of the Chief Information Officer to imply or endorse the use of any specific commercial vendor standards, designs or hardware. For the purposes of this document, the uses for video acquisition, contribution/exchange, production and distribution within NASA are considered as falling into one of two broad categories: Engineering and Publication. Engineering video is defined as video imagery that is acquired primarily for the purpose of being used by NASA or other authorized personnel, either in real-time or post-event, to observe, document, or analyze a NASA technical or operational activity. Examples of Engineering video include imagery of space launch and space flight activities, flight vehicle tests, laboratory and facility testing, scientific experiments, and training activities. Publication video is defined as video imagery that is acquired primarily for the purpose of being integrated into live television segments or edited programs that are created for disseminating information concerning NASA activities within the agency and/or for release to the news media or the public. Examples of these programs include educational or training videos, televised briefings or press conferences, video-file material, live-shots and video coverage of other NASA events. Acquisition for Publication video often strives for high artistic as well as high technical imaging performance. It is also noted that Publication video programs may be produced partially or in their entirety using video imagery originally acquired for Engineering purposes. NASA organizations must carefully determine their requirements and then select and use appropriate equipment and systems which are compliant with this standard for satisfying their particular video imagery needs.
