Embodiment Construction

[0062] The following description focuses on an embodiment of the invention applicable to a virtual reality system. However, it will be appreciated that the invention is not limited to this application, but may be applied to many other systems for distributing, processing and / or presenting audiovisual data.

[0063] This description will further focus on the handling and handling of audiovisual data in the context of a client-server approach supported by a network, which may in particular be a public network such as the Internet. However, it will again be appreciated that this is only an exemplary application of the principles and methods described, and that these may be used in many other systems and applications. Included are eg systems where the audiovisual data is provided in the form of a dedicated data stream transmitted directly to the processing / rendering device, or embodiments where the rendering device itself retrieves or generates the audiovisual data.

Abstract

An apparatus for processing audiovisual data for a scene comprises a receiver (201) for receiving audiovisual data for the scene. The audiovisual data comprises audio data for the scene comprising a plurality of audio elements and image data for at least a first image of the scene where the first image has a first aspect ratio. An image remapper (203) performs a content dependent non-uniform mapping of the first image to a second image which has a different aspect ratio. The image remapper (207) is arranged to generate mapping data describing the content dependent non-uniform mapping. An audio remapper (207) replaces a first audio element of the plurality of audio elements by a second audio element generated by modifying a spatial property for the first audio element in response to the mapping data. The spatial property being modified may be a position and / or spatial spread of the first audio element.

Description

technical field [0001] The present invention relates to apparatus and methods for processing audiovisual data, and in particular but not exclusively to the processing of audiovisual data for eg providing a virtual reality experience. 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 for various ...
