Encoding and decoding using independent rectangular sub-sections

A non-transitory computer-readable storage medium having stored thereon an encoded bitstream for decoding by a processor, the encoded bitstream comprising:

• encoded data for a first rectangular sub-section of a current frame, wherein the current frame includes at least one other sub-section that is independent of the first rectangular sub-section;
• and
• data indicating an encoded size of the encoded data, wherein, the processor executes instructions to:
• generate decoded image data, wherein to generate the decoded image data the processor executes the instructions to decode, in accordance with the data indicating the encoded size, as an independent image, the encoded data for the first rectangular sub-section;
• generate reconstructed frame data in accordance with the decoded image data;
• and
• output the reconstructed frame data.

An apparatus comprising:

• a memory storing instructions for decoding using tiling;
• and
• a processor that executes the instructions to:
• generate reconstructed frame data, wherein, to generate the reconstructed frame data, the processor executes the instructions to decode a current frame from an encoded bitstream, wherein, to decode the current frame, the processor executes the instructions to:
• access, from the encoded bitstream, data indicating an encoded size of a first rectangular sub-section of the current frame, wherein the current frame includes at least one other sub-section that is independent of the first rectangular sub-section;
• generate decoded image data, wherein to generate the decoded image data the processor executes the instructions to decode, in accordance with the data indicating the encoded size, as an independent image, encoded data from the encoded bitstream for the first rectangular sub-section;
• and
• generate the reconstructed frame data in accordance with the decoded image data;
• and
• output the reconstructed frame data.
