Video frame reconstruction

A method comprising:

• generating a number of initial reconstructed macro block lines by encoding the number of initial reconstructed macro block lines from a first buffer holding a current frame having a number of lines;
• placing the number of initial reconstructed macro block lines in a first in first out buffer sized to hold the number of initial reconstructed macro block lines;
• and
• incrementally, until all the number of lines in the current frame have been processed:
• generating an additional reconstructed macro block line by encoding the next line in the current frame using at least one reconstructed macro block line in the first in first out buffer;
• placing, sequentially in a reference buffer, a reconstructed macro block line pulled from the tail of the first in first out buffer;
• and
• pushing the additional reconstructed macro block line onto the head of the first in first out buffer.

An apparatus comprising:

• a first buffer to hold a current frame, the current frame having a number of lines;
• a line encoder to generate a reconstructed macro block line for each of the number of lines;
• a first in first out buffer sized to hold a number of reconstructed macro block lines;
• and
• a reference buffer to hold reconstructed macro block lines output from the first in first out buffer.

A system comprising:

• a video input;
• an encoder including:
• a first buffer to hold a current frame, the current frame having a number of lines;
• a line encoder to generate a reconstructed macro block line for each of the number of lines;
• a first in first out buffer sized to hold a number of reconstructed macro block lines;
• and
• a reference buffer to hold reconstructed macro block lines output from the first in first out buffer;
• and
• an encoded video output to output an encoded video stream.

At least one non-transitory machine-readable medium comprising one or more instructions, which, if executed by a processor, cause a computer to:

• generate a number of initial reconstructed macro block lines by encoding the number of initial reconstructed macro block lines from a first buffer holding a current frame having a number of lines;
• place the number of initial reconstructed macro block lines in a first in first out buffer sized to hold the number of initial reconstructed macro block lines;
• and
• incrementally, until all the number of lines in the current frame have been processed:
• generate an additional reconstructed macro block line by encoding the next line in the current frame using at least one reconstructed macro block line in the first in first out buffer;
• place, sequentially in a reference buffer, a reconstructed macro block line pulled from the tail of the first in first out buffer;
• and
• push the additional reconstructed macro block line onto the head of the first in first out buffer.
