摘要： A method for processing video content is disclosed. The method comprises: receiving, in a hardware device connected in operation to a computer, encrypted, encoded video content; decrypting the encrypted, encoded video content to form decrypted, encoded video content; decoding a first portion of the decrypted, encoded video content to form a decrypted, decoded video content portion; re-encrypting the decrypted, decoded video content portion to form a re-encrypted, decoded video content portion; re-encrypting a second portion of the decrypted, encoded video content to form a re-encrypted, encoded video content portion; and outputting the re-encrypted, decoded video content portion and the re-encrypted, encoded video content portion to the computer.

摘要： A system for displaying electronic program guide information about a plurality of video items on a screen, the system including a display module to display a plurality of pages layering into the screen, each of the pages including a plurality of graphical panels associated with the video items, and a user input module to receive a user input to turn at least one of the pages such that the at least one page is peeled away from other ones of the pages in order to bring the graphical panels of the at least one page in or out of view, wherein the display module is operative to show the turning of the at least one page bringing the at least one page in or out of view. Related apparatus and methods are also described.

摘要： The present invention relates to a method and apparatus for determining visually noticeable differences between two input images. A first contrast image is generated from the first input image and a second contrast image is generated from the second input image. A contrast difference image is then formed from the two contrast images. A mean absolute difference is calculated between blocks of pixels of the first and second input image. Pixels in the contrast difference image which exceed a first threshold produce a first threshold signal and if the mean absolute difference exceeds a second threshold so a second threshold signal is produced. A detection signal is produced from the threshold signals.
