Data processing for immersive media

A data processing apparatus, comprising:

• processing circuitry configured to:
• obtain metadata of immersive media, the metadata including zoom region information indicating a zoom region of the immersive media and automatic zooming information associated with the zoom region, the automatic zooming information including;
• zoom mode information indicating whether an automatic zooming mode is enabled for the zoom region,
• a step value indicating a number of automatic zooming steps to be sequentially performed when the automatic zooming mode is enabled,
• a respective zoom ratio for each of the automatic zooming steps, and
• a respective zoom duration for each of the automatic zooming steps;
• obtain encoded data of the immersive media that corresponds to the zoom mode information when the zoom mode information included in the automatic zooming information indicates that the automatic zooming mode is enabled for the zoom region;
• and
• perform zoom processing sequentially on the zoom region of the immersive media during playback of the encoded data according to the automatic zooming information included in the metadata when the zoom mode information indicates that the automatic zooming mode is enabled for the zoom region.

A non-transitory computer readable storage medium, storing instructions which when executed by a processor cause the processor to perform:

• obtaining metadata of an immersive media, the metadata including zoom region information indicating a zoom region of the immersive media and automatic zooming information associated with the zoom region, the automatic zooming information including:
• zoom mode information indicating whether an automatic zooming mode is enabled for the zoom region,
• a step value indicating a number of automatic zooming steps to be sequentially performed when the automatic zooming mode is enabled,
• a respective zoom ratio for each of the automatic zooming steps, and
• a respective zoom duration for each of the automatic zooming steps;
• obtaining, by processing circuitry, encoded data of the immersive media that corresponds to the zoom mode information when the zoom mode information included in the automatic zooming information indicates that the automatic zooming mode is enabled for the zoom region;
• and
• performing zoom processing sequentially on the zoom region of the immersive media during playback of the encoded data according to the automatic zooming information included in the metadata when the zoom mode information indicates that the automatic zooming mode is enabled for the zoom region.
