Abstract

A basic high-definition image is divided into tiles. Each of the tiles is analyzed to determine how it can be compressed. The tiles are both compressed and reduced in size according to the desired target, where the target is how many pixels are available on the screen of a device that is going to be used to display the video.

Claims

1. a method, comprising:

obtaining a high-definition frame;

dividing said high-definition image into a plurality of areas, each area representing only a part of the entire high definition frame;

determining, for each area, an amount of motion within the area as compared with a similar area for a different time;

first compressing areas which have motion less than a specified amount using a first compression technique, and compressing areas which have motion greater than said specified amount using a second compression technique different than the first compression technique to form a compressed video frame;

second compressing other video frames using the same technique as said first compressing; and

sending a compressed video over a cellular link to a specified wireless communicator.

2. A method as in claim 1, further comprising determining a screen size of a cellular phone that will display the frame, and wherein said first compressing comprises compressing the high-definition frame to a fraction of its original size, wherein the fraction is based on a difference between a total number of pixels in the high-definition frame and a total number of pixels in the screen size of the cellular phone.

3. A method as in claim 1, wherein said first compression technique is a doublet transformation, and said second compression technique is an analysis filter transformation.

4. A method as in claim 1, further comprising analyzing each area of the frame to determine if the each area can be compressed in both horizontal and vertical directions.

5. A method as in claim 1, further comprising rotating the frame to display the frame on the screen of a cellular telephone at an orthogonal orientation relative to an original frame.

6. A method as in claim 2, wherein said first compressing uses a fractal reduction technique.

7. A method, comprising:

obtaining a high definition frame of a high definition video, wherein said high definition frame has a size of at least 720i;

determining plural different smaller sizes of plural different screens, each of said plural different screens being for a different cell phone, said screens including at least a first screen having a first size, and a second screen having a second size;

determining a fraction between a size of said high definition frame and a size of said first screen, and a second fraction between said size of said high definition frame and a size of said second frame; and

carrying out a first compression of said high definition frame to form said high definition frame into the size of said first screen, and carrying out a second fraction between said high definition frame and said second screen to form said high definition frame into the size of said second screen.

8. A method as in claim 7, further comprising rotating the high definition frame to an orthogonal orientation as part of said forming said high definition frame into the size of said second screen.

9. A method as in claim 7, further comprising third and fourth compressions, and wherein said compressions reduce said high definition frame to sizes of 240×

160, 240×

320, 324×

416, and 640×

200.

10. A method, comprising:

obtaining a high definition frame of high definition video, having a size of at least 720i;

determining a size of a screen on a cellular phone that is to display said high definition video;

reducing the size of said high definition frame to fit the screen, and also rotating the high definition frame to an orthogonal configuration to fit the screen.

11. A method as in claim 10, wherein said reducing comprises determining plural different smaller sizes of plural different screens, each of said plural different screens being for a different cell phone, said screens including at least a first screen having a first size, and a second screen having a second size;

determining a fraction between a size of said high definition frame and a size of said first screen, and a second fraction between said size of said high definition frame and a size of said second frame; and

carrying out a first compression of said high definition frame to form said high definition frame into the size of said first screen, and carrying out a second fraction between said high definition frame and said second screen to form said high definition frame into the size of said second screen.
