Repacking of panoramic video based on standard image formats

1. A method for transmitting panoramic video encoded at a higher resolution using an output encoding at a lower resolution, comprising:

determining repacking parameters comprising a number of slices into which to slice each input frame of the panoramic video; and a number of stacks associated with an output encoding; wherein said number of slices and stacks enable the said input frame to be encoded based on the output encoding without downscaling;

slicing each input frame into the number of slices; and

stacking each slice into encoded frames of the output encoding.

2. The method of claim 1 , further comprising compressing each encoded frame.

3. The method of claim 1 , further comprising transmitting the encoded frames to a video destination together with metadata to facilitate decoding of the encoded frames.

4. The method of claim 3 , wherein the metadata comprises the number of slices.

5. The method of claim 3 , wherein the metadata comprise the number of stacks.

6. A method for processing video, comprising:

determining repacking parameters for repacking input panoramic video encoded at a higher resolution into corresponding encoded panoramic frames encoded at a lower resolution without down-scaling;

performing a repacking operation to repack the input panoramic video into the encoded panoramic frames.

7. The method of claim 6 , wherein the repacking parameters comprise a number of slices into which to slice each frame of the input panoramic video.

8. The method of claim 7 , wherein the repacking parameters comprise a number of stacks into which to pack the slices in each encoded panoramic frame.

9. The method of claim 6 , wherein the repacking parameters specify a number of overlapping pixels to include with adjacent slices.

10. Apparatus, comprising:

a processor; and

a memory, the memory storing instructions which when executed by the processor performs a method for processing, video, comprising:

determining repacking parameters for repacking input panoramic video encoded at a homer resolution into corresponding encoded panoramic frames encoded at a lower resolution without down-scaling;

performing a repacking operation to repack the input panoramic video into the encoded panoramic frames.

11. The apparatus of claim 10 , wherein the repacking parameters comprise a number of slices into which to slice each frame of the input panoramic video.

12. The apparatus of claim 11 , wherein the repacking parameters comprise a number of stacks into which to pack the slices in each encoded panoramic frame.

13. The apparatus of claim 10 , wherein the repacking parameters specify a number of overlapping pixels to include with adjacent slices.

14. A non-transitory computer readable medium having stored thereon a sequence of instructions which when executed by a processor causes a system to perform a method for processing video, comprising:

determining repacking parameters for repacking input panoramic video encoded at a higher resolution into corresponding encoded panoramic frames encoded at a lower resolution without down-scaling;

performing a repacking operation to repack the input panoramic video into the encoded panoramic frames.

15. The computer readable medium of claim 14 , wherein the repacking parameters comprise a number of slices into which to slice each frame of the input panoramic video.

16. The computer readable medium of claim 14 , wherein the repacking parameters comprise a number of stacks into which to pack the slices in each encoded panoramic frame.

17. The computer readable medium of claim 14 , wherein the repacking parameters specify a number of overlapping pixels to include with adjacent slices.
