Abstract
A method and a device for signaling multiple audio mixing gains in a teleconference using Real-time Transport Control Protocol (RTCP) feedback. The method includes receiving an input audio stream from a 360-degree video stream, the input audio stream including mixing gains, declaring an RTCP feedback rate for receiving the mixing gains, based on an allocated bandwidth, and signaling the mixing gains using the declared RTCP feedback rate. The mixing gains may include audio gains from the input audio stream and audio gains from overlay audio streams. The RTCP feedback rate used for signaling the mixing gains may be constant or event-based feedback rate.
Claims20
A method for signaling multiple audio mixing gains in a teleconference using Real-time Transport Control Protocol (RTCP) feedback, performed by at least one processor and comprising:
- receiving an input audio stream from a 360-degree video stream, the input audio stream including mixing gains;
- declaring an RTCP feedback rate, which indicates a trigger of initiating an RTCP feedback and comprises a different bitrate than a streaming of the input audio stream, for receiving the mixing gains, based on an allocated bandwidth;
- and
- signaling the mixing gains using the declared RTCP feedback rate.
A device for signaling multiple audio mixing gains in a teleconference using Real-time Transport Control Protocol (RTCP) feedback, the device comprising:
- at least one memory configured to store program code;
- and
- at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
- receiving code configured to cause the at least one processor to receive an input audio stream from a 360-degree video stream, the input audio stream including mixing gains;
- declaring code configured to cause the at least one processor to declare an RTCP feedback rate, which indicates a trigger of initiating an RTCP feedback and comprises a different bitrate than a streaming of the input audio stream, for receiving the mixing gains, based on an allocated bandwidth;
- and
- signaling code configured to cause the at least one processor to signal the mixing gains using the declared RTCP feedback rate.
A non-transitory computer readable medium storing instructions, the instructions comprising:
- one or more instructions that, when executed by at least one processor of a device for signaling multiple audio mixing gains in a teleconference using Real-time Transport Control Protocol (RTCP) feedback storing instructions that, cause the at least one processor to:
- receive an input audio stream from a 360-degree video stream, the input audio stream including mixing gains;
- declare an RTCP feedback rate, which indicates a trigger of initiating an RTCP feedback and comprises a different bitrate than a streaming of the input audio stream, for receiving the mixing gains, based on an allocated bandwidth;
- and
- signal the mixing gains using the declared RTCP feedback rate.
