Video conversion technology
View Patent ↗Video conversion technology, in which a first stream of video content is accessed and multiple, different layers are extracted from the first stream of the video content. Each of the multiple, different layers are separately processed to convert the multiple, different layers into modified layers that each have a higher resolution. The modified layers are reassembled into a second stream of the video content that has a higher resolution than the first stream of the video content.

extracting a red color layer by identifying red color values in the first stream of the video content and separating the identified red color values into the red color layer,
extracting a green color layer by identifying green color values in the first stream of the video content and separating the identified green color values into the green color layer; and
extracting a blue color layer by identifying blue color values in the first stream of the video content and separating the identified blue color values into the blue color layer.
6. The method of claim 1 , wherein reassembling each of the modified layers into a single stream of high resolution television video comprises identifying features that are present in each of the modified layers and using the identified features to align the first modified layer, the second modified layer, and the third modified layer in the single stream of high resolution television video.
7. The method of claim 1 , wherein reassembling each of the modified layers into a single stream of high resolution television video comprises weighting each of the modified layers differently than the other layers in the single stream of high resolution television video.
8. The method of claim 1 , wherein the resolution of the high resolution television video has a frame rate of 23.98 frames per second and a resolution of 1480×1080.
9. The method of claim 1 ,
wherein the analog version of a standard definition television video program is stored on a first electronic storage of a first type; and
wherein the single stream of high resolution television video is stored in a second electronic storage of a second, different type.

at least one processor; and
at least one memory coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least
one processor to perform operations comprising:
accessing, from an electronic storage, an analog version of a standard definition television video program;
generating a digital version of the standard definition television video program by performing a decoding process on the analog version of the standard definition television video program;
extracting, from the digital version of the standard definition television video program, a first color layer, a second color layer, and a third color layer, wherein each of the first color layer, the second color layer, and the third color layer are different from each other;
converting each of the first color layer, the second color layer, and the third color layer into a modified layer;
performing one or more processing operations on each of the modified layers;
reassembling each of the modified layers into a single stream of high resolution television video, wherein the resolution of the high resolution television video is higher than the resolution of the standard definition television video program.
11. The system of claim 10 , wherein generating a digital version of the standard definition television program comprises performing a decoding process on the analog version of the standard definition television program by applying a three-dimensional comb decoder to the standard definition television program.
12. The system of claim 10 , wherein performing one or more processing operations on each of the modified layers comprises performing a combination of blurring, de-interlacing, resizing, speed changing, sharpening, and chromatic adjustment.
13. The system of claim 10 , wherein performing blurring on each of the modified layers comprises performing frame by frame detection and the blurring of channel edges in each of the first color layer, the second color layer, and the third color layer.
14. The system of claim 10 , wherein extracting, from the digital version of the standard definition television video program, a first color layer, a second color layer, and a third color layer, wherein each of the first color layer, the second color layer, and the third color layer are different from each other comprises:
extracting a red color layer by identifying red color values in the first stream of the video content and separating the identified red color values into the red color layer,
extracting a green color layer by identifying green color values in the first stream of the video content and separating the identified green color values into the green color layer; and
extracting a blue color layer by identifying blue color values in the first stream of the video content and separating the identified blue color values into the blue color layer.
15. The system of claim 10 , wherein reassembling each of the modified layers into a single stream of high resolution television video comprises identifying features that are present in each of the modified layers and using the identified features to align the first modified layer, the second modified layer, and the third modified layer in the single stream of high resolution television video.
