scope:

This Recommendation describes the service scenarios, functional requirements and reference model for visual surveillance system interworking (VSSI), based on the requirements and architectures defined by [ITU-T F.743], [ITU-T H.626], [ITU-T H.626.1] and [ITU-T H.627].

A visual surveillance (VS) service is a telecommunication service focusing on video (and audio) application technology, which is used to remotely capture multimedia (such as audio, video, image and various alarm signals), and present them to end users in a friendly manner (including accessibility aspects), based on a broadband network with ensured quality, security and reliability. The VSSI mechanism can achieve cross-system scheduling of multimedia (such as video, audio and image) and enables the resource and data sharing of different visual surveillance systems (VSSs).
