Recommendation: Closed Circuit Television(CCTV) Digital Video Export Profile – Level 0

Abstract

This document is a recommendation prescribing a data interchange format for the syntactic representation of information needed to achieve a base “Level 0” of interoperability when exporting and processing video recordings captured by closed circuit television (CCTV) digital video recording (DVR) systems. In summary, this profile of standards leverages the MP4 file container, storing one H.264 encoded digital video bitstream containing embedded time codes defined by the Motion Industry Standards Board (MISB), and Extensible Metadata Platform (XMP)-formatted metadata that is used to determine a CCTV DVR System Clock Offset. The video output format described in this document has been developed to support law enforcement investigations. This specification was prepared by the National Institute of Standards and Technology (NIST), in collaboration with the Federal Bureau of Investigation, and in conjunction with CCTV / DVR community.
