Abstract
Methods and apparatus for packing images into a frame and/or including additional content and/or graphics are described. A composite image is generated including at least one image in addition to another image and/or additional image content. A playback device received an encoded frame including a captured image of a portion of and environment and the additional image content. The additional image content is combined with or used to replace a portion of the image of the environment during rendering. Alpha value mask information is communicated to the playback device to provide alpha values for use in image combining. Alpha values are communicated as pixel values in the encoded frame or as additional information. One or more mesh models and/or information on how to map image content to the one or more mesh models is communicated to the playback device for use in rendering image content recovered from a frame.
