NexVDO SDK Integrates Audio Backchannel for Smart City and Broadcast
NexVDO SDK has officially announced the integration of the Audio Backchannel application, catering to the needs of the security and broadcasting markets. This innovative technology is set to bring enhanced functionality and superior user experiences to video surveillance and streaming applications.
As a global standardization organization, ONVIF ( Open Network Video Interface Forum ) has been dedicated to developing and promoting open standards for IP video surveillance products. Concurrently, RTSP ( Real-Time Streaming Protocol ) serves as a standard protocol for transmitting video and audio over the Internet. Within the standards of ONVIF and RTSP, the definition of Back channel introduces an additional extended channel.
Specifically, Back channel Audio serves as an extended channel for handling audio, enabling bidirectional audio transmission from the client to the server. Its purpose is to establish bidirectional audio communication between devices, allowing users to engage in voice conversations or other audio-related interactions while watching videos.
The technology finds diverse applications in various scenarios, including the following common use cases :
Remote Monitoring and Security Systems
In remote monitoring applications, Backchannel Audio allows monitoring personnel to deliver voice warnings, engage in conversations, or issue instructions, thereby enhancing the efficiency of security systems.
Remote Education
Teachers and students can utilize Audio Backchannel for voice communication, providing a richer educational interactive experience.
Remote Collaboration and Team Cooperation
In remote collaboration tools and team cooperation platforms, Audio Backchannel supports voice communication among team members, fostering more efficient collaboration and communication.
Game Voice Chat
In online multiplayer games, Audio Backchannel can be used for in-game voice chat among players, enhancing the social and collaborative aspects of gaming.
Audio Broadcasting
In audio broadcasting applications, Audio Backchannel provides interaction between broadcasters and listeners, allowing listeners to engage in real-time interactions through voice with the broadcaster.
In conclusion, Audio Backchannel offers a standardized mechanism for different manufacturers' devices to engage in bidirectional communication within the same network environment, leading to enhanced functionality and improved collaboration. Its extensive range of applications makes it an ideal choice for various scenarios requiring bidirectional audio communication, including security surveillance, education, instant messaging and audio broadcasting, among other fields.
