Abstract: A method, apparatus, and system for determining a horizontal resolution and a phase of an analog video signal arranged to display a number of scan lines each formed of a number of pixels is described. A number of initialization values are set where at least one of the initialization values is a current horizontal resolution and then a difference value for each immediately adjacent ones of the pixels is determined. Next, an edge flag value based upon the difference value is stored in at least one of a number of accumulators such that when at least one of the accumulators has a stored edge flag value that is substantially greater than those stored edge flag values in the other accumulators, then the horizontal resolution is set to the current resolution.

Abstract: A method and an apparatus for performing the method of decoding and playing in reverse MPEG encoded content. The MPEG encoded content comprises a plurality of pictures frames. The picture frames are comprised of one or more picture frame types selected from the group of picture frame types including I-frames, P-frames, and B-frames. The method and the apparatus for performing the method comprise the steps of obtaining a group of MPEG picture frames (“GOP”), determining the total number of picture frames in the GOP, and setting an index value equal to the total number of picture frames in the GOP. Next, a picture frame F that has a display order equal to the index value is decoded and displayed, and the earliest B-frame that depends upon frame F is determined. All the B-frames that depend upon frame F are decoded and displayed from highest display order to lowest display order, and the index value then is set to a value equal to one less than the display order of the earliest B-frame that depends upon frame F. The process then repeats by obtaining, decoding and displaying the next frame F having a display order equal to the index value, and decoding and displaying the B-frames that depend upon the frame F.

Abstract: Keys (e.g., decryption key, authentication key) are stored in a non-volatile memory of a display unit. The keys are retrieved in encrypted form into an integrated circuit. The integrated circuit decrypts the keys and uses the keys. As the keys are available in decrypted form only within the integrated circuit and potentially only during use, the keys may not be available to unauthorized third parties.
Abstract translation: 密钥（例如，解密密钥，认证密钥）被存储在显示单元的非易失性存储器中。 密钥以加密形式被检索为集成电路。 集成电路解密密钥并使用密钥。 由于密钥只能在集成电路内部以解密形式提供，并且潜在地仅在使用期间，密钥可能不会对未经授权的第三方提供。

Abstract: A processor having a limited amount of local memory for storing code and/or data utilizes a program stored in external memory. The program stored in external memory is configured into blocks which can be loaded individually into the local memory for execution. Queuing the individual blocks of code allows the program to be executed by the processor and also facilitates loading of the subsequent code to be executed. A semaphore system can be utilized to indicate which blocks of local memory are available/unavailable. A group of transfer parameters as queue entries allow code and data for an algorithm to be transferred between both local and external memory.

Abstract: A method of generating an upsampled target pixel positioned between two lines of input source data includes the step of comparing pixels of different lines of the source data in a region surrounding the upsampled target pixel to be generated in at least two different directions. An interpolation direction based on the comparison is selected and interpolations between selected pixels of the source data in the determined interpolation direction are carried out to compute intermediate pixels on a line segment passing through the upsampled target pixel. An interpolation between the intermediate pixels is carried out to generate the upsampled target pixel. An apparatus for performing the method is also disclosed.

Abstract: The invention provides for automatically identifying the location of a displayed video window based upon a characterization of selected portions of the image for realness based upon a distribution of luminance values for the selected portions. The image is then searched mathematically for a large rectangle of realness, and if found, a similar operation is performed in a smaller rectangle around each of the edges of the large rectangle, in turn, zooming in to a resolution of one pixel, thus identifying the position of the edge. This process can be repeated as often as necessary in order to maintain a fix on the edges of the video window.
