Abstract
Aspects of the disclosure provide an apparatus that includes interface circuitry and processing circuitry. The interface circuitry is configured to receive signals carrying metadata that associates a region of interest in a first visual view provided by a first visual track with the first visual track and a second visual track that provides a second visual view that is a part of the first visual view. The processing circuitry is configured to parse the metadata, determine, when the region of interest is selected, the second visual track to provide visual data, and generate images for the region of interest based on the visual data from the second visual track.
