摘要： The present invention is directed to systems, methods and apparatus for processing media content for reproduction by a first apparatus. The method includes obtaining pose information indicative of a position and/or orientation of a user. The pose information is transmitted to a second apparatus that provides the media content. The media content is rendered based on the pose information to obtain rendered media content. The rendered media content is transmitted to the first apparatus for reproduction. The present invention may include a first apparatus for reproducing media content and a second apparatus storing the media content. The first apparatus is configured to obtain pose information indicative and transmit the pose information to the second apparatus; and the second apparatus is adapted to: render the media content based on the pose information to obtain rendered media content; and transmit the rendered media content to the first apparatus for reproduction.

摘要： A method for generating a bitstream indicative of an object based audio program is described. The bitstream comprises a sequence of containers. A first container of the sequence of containers comprises a plurality of substream entities for a plurality of substreams of the object based audio program and a presentation section. The method comprises determining a set of object channels. The method further comprises providing a set of object related metadata for the set of object channels. In addition, the method comprises inserting a first set of object channel frames and a first set of object related metadata frames into a respective set of substream entities of the first container. Furthermore, the method comprises inserting presentation data into the presentation section.

摘要： Some disclosed methods involve encoding or decoding directional audio data. Some encoding methods may involve receiving a mono audio signal corresponding to an audio object and a representation of a radiation pattern corresponding to the audio object. The radiation pattern may include sound levels corresponding to plurality of sample times, a plurality of frequency bands and a plurality of directions. The methods may involve encoding the mono audio signal and encoding the source radiation pattern to determine radiation pattern metadata. Encoding the radiation pattern may involve determining a spherical harmonic transform of the representation of the radiation pattern and compressing the spherical harmonic transform to obtain encoded radiation pattern metadata.
