摘要： A system and method for detecting sampling frequency in a video signal. A method comprises applying a first test to determine the sampling frequency of the image signal, applying a second test to determine the sampling frequency of the image signal, and verifying the sampling frequency of the image signal. The first test compares detected timing characteristics of the image signal with known timing characteristics of a set of known standard image signals and the second test measures data characteristics of image data in the multiple image frames of the image signal. Combining both detected image characteristics and measured image characteristics based techniques to determine sampling frequency improves the possibility of correctly detecting an image signal's sampling frequency.

摘要： A system and method for tuning a sampling frequency. A method comprises detecting a sampling frequency of an analog image signal, generating a set of histograms from samples of pixels from the analog image signal, using the set of histograms to determine whether the detected sampling frequency is substantially equal to a natural sampling frequency of the analog image signal, and sampling the analog image signal at the detected sampling frequency to produce image data. The samples are taken at the detected sampling frequency and at a different sampling phase for each of the histograms, and each histogram is for samples from a single image.

摘要： A PDF document is repurposed to save paper and ink. Preprocessing is performed on the PDF document. The PDF document has a first quantity of pages of content and a first quantity of ink. Further, complexity analysis is performed on the PDF document. In addition, a document object model based on the PDF document is created. In addition, content re-layout is performed on the PDF document based on the content repurposing such that a printer prints the PDF document with the content in a transformed format that results in a second quantity of pages being printed without falling below a predetermined readability threshold and a second quantity of ink being utilized. The second quantity of pages is less than the first quantity of pages. The second quantity of ink is less than the first quantity of ink.
