Methods and systems for compression that maintains parameters related to uncompressed video (PRTUV) while changing video compression ratios on-the-fly. One embodiment of a system includes: A video transmitter that receives incoming high-definition uncompressed video (HD-UV) characterized by certain PRTUV. The video transmitter compresses the incoming HD-UV into a first compressed video of ratio between 1:1 and 5:1, and sends it over a communication link to a receiver that decompresses the video to an outgoing HD-UV. When the video transmitter receives a command to smoothly change on-the-fly the compression to a second compressed video of ratio between 2:1 and 10:1, it makes the change without interrupting the continuous flow of the incoming HD-UV. Wherein the outgoing HD-UV maintains the PRTUV before, during, and after the change from the first compressed video to the second compressed video.

Methods and systems for smooth switching of video sources. One method includes the steps of: Inferring that first and second network paths share a common link that has insufficient bandwidth to carry both the respective first and second incoming high-definition uncompressed videos (HD-UVs) generated by first and second real-time video encoders (RT-VEs). And synchronizing a smooth switching between the first and second incoming HD-UVs by: indicating the first and second RT-VEs to increase their first and second compression ratios to ratios that enable the common link to carry both the first and second compressed videos; indicating a video switcher to perform the smooth switching between the first and second corresponding outgoing HD-UVs; indicating the first RT-VE to stop sending the first compressed video after the smooth switching; and indicating the second RT-VE to decrease the second compression ratio.

The disclosed method may include (1) receiving an input datum to be processed using a non-linear function to produce an output datum, (2) comparing the input datum to a plurality of indexes of a lookup table, where the indexes designate input endpoints of a plurality of piecewise-linear sections approximating the non-linear functions, and where the lookup table further includes, for each of the indexes (a) a slope of the piecewise-linear section corresponding to the index, and (b) an axis intercept of the piecewise-linear section corresponding to the index (2) selecting, based on comparing the input datum to the plurality of indexes, an index that designates the piecewise-linear section associated with the input datum, and (4) calculating, using the slope and the axis intercept corresponding to the selected index, the output data corresponding to the input datum. Video processing systems employing such a method are also disclosed.

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.
