Motion vector reuse for adaptive bit rate streaming

A method for reusing motion vectors across distributed devices, the method comprising:

• determining a first adaptive bit rate (ABR) profile and a second ABR profile associated with a video content item;
• performing motion estimation on the video content item to generate motion vectors for the video content item;
• encoding the video content item using the motion vectors and based at least in part on the first ABR profile to generate a first encoded stream;
• initiating transmission of information describing the motion vectors and the video content item to a secondary device, wherein the secondary device encodes the video content item using the information describing the motion vectors and based at least in part on the second ABR profile;
• and
• transmitting first segments of the first encoded stream in response to requests therefor.

A computer program product comprising instructions stored in a tangible computer-readable storage medium, the instructions comprising:

• instructions for determining a first adaptive bit rate (ABR) profile and a second ABR profile associated with a video content item;
• instructions for performing motion estimation on the video content item to generate motion vectors for the video content item;
• instructions for encoding the video content item using the motion vectors and based at least in part on the first ABR profile to generate a first encoded stream;
• instructions for modifying the motion vectors to generate modified motion vectors;
• instructions for encoding the video content item using the modified motion vectors and based at least in part on the second ABR profile to generate a second encoded stream;
• and
• transmitting segments of the first and second encoded streams in response to requests therefor.
