Problems solved by technology

While headsets may attempt to block light and sound, this is often only partially achieved
Also, in AR apps, the user is often also able to experience the local environment as part of the experience, so completely blocking that environment is impractical

Embodiment Construction

[0057] Virtual (including augmented) experiences that allow users to move around in a virtual or augmented world are becoming increasingly popular, and services are being developed to meet these needs. In many of these approaches, visual and audio data can be dynamically generated to reflect the user's (or viewer's) current gesture.

[0058] In the art, the terms placement and attitude are used as general terms for position and / or direction / orientation. A combination of position and direction / orientation such as object, camera, head or view may be referred to as pose or placement. Thus, a placement or pose indication may comprise up to six values / components / degrees of freedom, where each value / component typically describes a separate property of the orientation / position or orientation / orientation of the corresponding object. Of course, in many cases placement or pose can be represented by fewer components, for example if one or more components are considered fixed or uncorrel...

Abstract

A distribution system comprises an audio server (101) for receiving incoming audio from remote clients (103) and for transmitting audio derived from the incoming audio to the remote clients (103). Anaudio apparatus comprises an audio a receiver (401) which receives data comprising: audio data for a plurality of audio components representing audio from a remote client of the plurality of remote clients; and proximity data for at least one of the audio components. The proximity data is indicative of proximity between remote clients. A generator (403) of the apparatus generates an audio mix fromthe audio components in response to the proximity data. For example, an audio component indicated to be proximal to a remote client may be excluded from an audio mix for that remote client.

Description

technical field [0001] The present invention relates to an audio device, an audio distribution system and methods therefor, and in particular but not exclusively to the use thereof to support augmented / virtual reality conferencing applications. Background technique [0002] In recent years, the variety and range of experiences based on audiovisual content has increased greatly, with new services and ways of utilizing and consuming such content constantly being developed and introduced. In particular, many spatial and interactive services, applications, and experiences are being developed to provide users with more engaging and immersive experiences. [0003] Examples of such applications include virtual reality (VR) and augmented reality (AR) applications that are quickly becoming mainstream, with many solutions targeting the consumer market. Many standardization bodies are also developing many standards. Such standardization activities are actively developing guidelines f...
