    摘要： Systems and methods for obtaining and maintaining operable and updated versions of software on a client, which may be a set-top box or a personal computer. A server automatically downloads software updates over a satellite link to a client after such upgrades become available at the server without requiring interaction with a user. Similarly, corrupted software is automatically replaced by the client first automatically detecting if a corrupted state exists in local software or data using a checksum technique. If such corruption is found, the client automatically connects over the Internet to a server that contains a replacement for the corrupted program or data. The client then automatically receives a download of the program or data from the server.

    摘要： A method for filtering data to be compressed by frame differencing is disclosed. In applications where large amounts of data must be either stored or transmitted, such as, for example, digital image data, various techniques are used to compress the data. One such technique is frame differencing wherein after a reference frame or key is encoded, only the differences between each frame and the immediately preceding frame in the sequence are encoded. The present invention operates as a pre-process or in conjunction with such a technique by determining which of the changed data points can be disregarded without significantly affecting, for example, the stored image, thereby reducing the amount of data which must be stored or transmitted. The determination is made in the present invention by comparing the pattern of changed data points in the vicinity of the data point under consideration with a set of pre-determined patterns.

    摘要： An apparatus and method useful for the efficient display of images on a computer display screen a display area description language is provided for describing and manipulating portions of a raster display screen. The area description language is comprised of a set of instructions and masks that define the areas and manipulations for a particular display. The area description language is used to define the location, dimension and contents of areas within a logical display grid. Each area description command is comprised of three components. First, each command has an associated scan count. The scan count defines which scan line or lines will be operated upon by the command. Secondly, each command has at least one instruction. The command instruction is used to define the location and the dimension of the area being defined by the command. The third component that may or may not exist in each command is a mask. The mask is used to define the individual pixels that will be merged with a new source image to create a modified image within the area defined by command instruction.

    摘要： A method for determining if uncompressed color video data was previously compressed and decompressed. Each block of color video data is examined to determine if the block was previously compressed with a predetermined compression algorithm that for example, selected fewer colors than were present in the original data. If it is determined that such compression has previously occurred, on recompression, a different algorithm is used to prevent introduction of color distortions.
