ONVIF Issues Final Release of Profile T for Advanced Video Streaming
Per Bjorkdahl, ONVIF.
PROFILE T, which will cover the streaming of metadata such as analytics and events for H.265 and H.264 video codecs, has just been released by ONVIF.
With Profile T, ONVIF is delivering a new media service to more easily incorporate new video and audio codecs as needed as the industry continues to advance. And with H.265, Profile T supports more efficient compression rates, which translates into decreased storage requirements on hard drives and less bandwidth usage – reducing the overall costs of system ownership.
“Profile T is an excellent example of how ONVIF has embraced technological advancements within its specifications to serve the changing requirements of this industry,” says Per Björkdahl, chairman of the ONVIF Steering Committee. “In addition to the H.265 support, Profile T standardizes analytics, metadata streaming and other important features to satisfy current and future market requirements for end users, systems integrators and consultants.”
The new Profile T features bi-directional audio streaming, supporting audio input as well as output from the camera. Using standardized event types, Profile T ensures that video management systems (VMNS) and other software clients use one set of events to support all cameras, regardless of manufacturer. This includes alerts such as tampering, digital input and relay output. It also enables a specific area of an image to be selected for analysis, using the conditional motion region detector configuration through the analytics service.
