Methods and apparatus for receiving and/or using reduced resolution images

A content playback device, comprising:

• memory that stores a mesh model of an environment having segments and a plurality of image maps each mapping a different number of pixels to the same segment of the environment;
• a network interface that receives an encoded image, captured in the environment and an indication that the resolution of the encoded image was reduced in accordance with a first resolution allocation corresponding to a first image map of the plurality of image maps;
• a decoder that decodes the encoded image;
• a processor that renders the decoded image by mapping the decoded image to the mesh model of the environment in accordance with the first image map to produce a first rendered image;
• and
• a display device that displays the first rendered image.

A non-transitory computer readable storage medium storing instructions that, when executed by a content playback device, cause the content playback device to:

• store a mesh model of an environment having segments;
• store a plurality of image maps, each of the plurality of image maps mapping a different number of pixels to the same segment of the environment;
• receive an encoded image, captured in the environment, and an indication that the resolution of the encoded image was reduced in accordance with a first resolution allocation corresponding to a first image map of the plurality of image maps;
• decode the encoded image;
• map the decoded image to the mesh model of the environment in accordance with the first image map to produce a first rendered image;
• and
• display the first rendered image on a display device.
