Independently coding frame areas

A method comprising:

• receiving an encoded bitstream;
• generating, by a processor, a reconstructed frame by decoding at least a portion of the encoded bitstream, wherein decoding includes:
• generating a first contiguous reconstructed area of the reconstructed frame by decoding first encoded data from the encoded bitstream;
• generating a second contiguous reconstructed area of the reconstructed frame by decoding second encoded data from the encoded bitstream, wherein decoding the second encoded data is performed independently of decoding the first encoded data, wherein decoding the second encoded data includes reading, from the encoded bitstream an offset indicating a location of the second encoded data in the bitstream;
• and
• including the first contiguous reconstructed area and the second contiguous reconstructed area in the reconstructed frame;
• and
• outputting the reconstructed frame.

An apparatus comprising:

• a processor configured to:
• identify an input frame from an input video stream;
• generate an output bitstream by encoding the input frame, wherein encoding the input frame includes:
• dividing the input frame into at least a first contiguous area of the input frame and a second contiguous area of the input frame;
• generating first encoded data by encoding the first contiguous area of the input frame;
• generating second encoded data by encoding the second contiguous area of the input frame, wherein encoding the second contiguous area of the input frame is performed independently of encoding the first contiguous area of the input frame;
• and
• including the first encoded data and the second encoded data in the output bitstream;
• and
• output the output bitstream, wherein to output the output bitstream, the processor is configured to include, in the output bitstream, an offset indicating a location of the second encoded data in the output bitstream.
