International. ONVIF, the leading global standardization initiative for IP-based physical security products, introduced the candidate version for Profile T, a specification project with advanced streaming capabilities that includes support for H.265 video compression and an expanded feature set that expands the capabilities of ONVIF video profiles for system integrators and end users.
ONVIF Profile T for advanced streaming employs a new multimedia service that enables High Efficiency Video Coding (HEVC) support, based on the H.265 international video compression standard that specifies how to decode data into viewable video. Supported Profile T clients support H.264 and H.265 video compression, while Profile T compatible devices support at least one of these formats. The new profile also encompasses active Transport Layer Security (TLS) communications and new features such as two-way audio streaming, event standardization, image settings, on-screen display settings, and more.
"Profile T expands the scope of the ONVIF video profile to include both standard H.264 video compression, which is currently highly used in video surveillance solutions, and H.265 video compression, which will become standard video compression in the very near future," said Fredrik Svensson, Chair of the ONVIF Profile T Working Group. "In addition to supporting multiple types of video compression, Profile T also ensures compatibility with motion detection, metadata streaming, analytics, and other important features that give system integrators and end users a standardized feature set, as well as interoperability between vendor solutions."
Profile T for advanced streaming supports transport between Websockets, giving users the ability to stream videos in a browser rather than a
Virtual Memory System (VMS). Profile T also features two-way audio, which is commonly used in citizen surveillance, transportation, and parking control, as well as in security applications that require two-way audio communication. Support for the TLS protocol adds another level of security for communications between Profile T-compliant clients and devices.
Profile T includes the standardization of events such as motion detection and manipulation. Digital input and relay output events are covered, as well as their configuration in the I/O device service, which can speed up installation. Profile T allows the configuration of zone motion detection using an analytical service, which means that a specific area of the image can be selected for analysis. Streaming metadata such as events and analytical data is also covered by Profile T.
ONVIF delivers a new profile first as a candidate version for at least 6 months, allowing members and other stakeholders a final implementation review. Once the process is complete, the final profile will be published and technology vendors will be able to test their products to see if they are compatible with the final version of Profile T. The intent of this process is to allow members to introduce supported products more quickly once the final version of Profile T is released in 2018.
Founded in 2008, ONVIF is a leading and widely recognized industry forum that drives interoperability of IP-based physical security products. The organization has a global membership base comprised of established camera companies, video management and access control systems, and nearly 8,000 products compatible with their profiles. With Profile S for video streaming; Profile G for registration and storage; Profile C for physical access control; Profile Q for enhanced functionality; Profile A for greater access to control configurations and the candidate version of the new Profile T for advanced streaming, ONVIF continues to work with its members to expand the number of IP interoperability solutions that ONVIF's compatible products can provide.
