摘要： A method and device for signaling multiple audio mixing gains in a teleconference using a single Real-time Transport Protocol (RTP) header extension is provided. The method includes receiving an input audio stream from a 360-degree video/audio stream that includes multiple mixing gains from the input audio stream and overlay audio stream, declaring a single RTP header extension (including one or more of an element identifier, a length of an extension element, and a magnitude of the mixing gains) for all the mixing gains, and signaling the mixing gains using the single RTP header extension. The single RTP header extension may use a one-byte or two-byte header extension format which is declared using a Session Description Protocol (SDP).

摘要： A method and 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 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.

摘要： A system and method of split rendering for lightfield or immersive media by using an edge-cloud and peer-to-peer based architecture. The system and method include the use of a combination of cloud-based devices and edge-devices to provide distributed processing in connection with the streaming of media, and in particular lightfield or immersive media, to an end user device. The system and method further include the use of multiple cloud and edge devices to provide parallel streaming of a given media package to an end user device.

摘要： Aspects of the disclosure provide methods and apparatuses for video conference and/or telepresence. In some examples, video conference/telepresence can be performed by multiple client devices, user devices and a media control device (e.g., server device). For example, a first client device determines a grouping control that limits a grouping of an overlay media from a second client device with an immersive media of the first client device, and transmits a grouping control signal indicative of the grouping control to inform a media control device. Further, the first client device provides one or more media including the immersive media to the media control device. The media control device can group a plurality of immersive media streams in a single or multiple groups based on the grouping control signal received from the first client device.

摘要： A method, a non-transitory computer readable medium, and a computer system is provided for handling video streams. The method may include: receiving a 360° video stream, the 360° video stream including a multiple overlay parameter; when the multiple overlay parameter is a first value, determining that overlaying the 360° video stream with two or more overlays is permissible by the user terminal, and displaying, by the user terminal, the 360° video stream with the two or more overlays; and when the multiple overlay parameter is a second value, determining that overlaying the 360° video stream with two or more overlays is not permissible and displaying the 360° video stream with zero overlays or one overlay.
