Apparatus and methods for video compression using multi-resolution scalable coding

A non-transitory computer-readable apparatus comprising a storage medium, the storage medium including a computer program comprising a plurality of instructions which are configured to, when executed by one or more processor apparatus, cause a computerized apparatus to:

• obtain a residual image based on a first full-resolution image and a second full-resolution image;
• detect a portion of the obtained residual image, the portion being viewed by a user;
• encode the portion of the obtained residual image;
• produce a high-fidelity bitstream based at least on the encode of the portion of the obtained residual image;
• and
• provide at least the produced high-fidelity bitstream to a client device of the user.

A computerized apparatus for providing video content, the computerized apparatus comprising:

• a processing apparatus;
• a network interface in data communication with the processing apparatus;
• a non-transitory computer-readable apparatus comprising a storage medium, the storage medium including a computer program comprising a plurality of instructions which are configured to, when executed by the processing apparatus, cause a computerized apparatus to:
• derive a difference image based at least on a first image and a second image;
• encode a portion of the derived difference image to generate an encoded portion, the encoded portion corresponding to a position of a viewport as reflected in data received from at least one client device via the network interface;
• and
• provide, to the network interface for distribution to the at least one client device, at least the encoded portion of the difference image corresponding to the position of the viewport.
