An image processing engine, comprising: a frame rate conversion entity configured to: (a) generate output pictures from input pictures, the output pictures comprising a set of first output pictures and a plurality of sets of second output pictures, each set of second output pictures being associated with one of the first output pictures, each of the first output pictures being derived from a respective one of the input pictures; and (b) control generation of the set of second output pictures associated with a particular first output picture based upon repetitive pattern presence detection within a related picture that is either (i) the particular first output picture or (ii) the input picture from which the particular first output picture was derived.

Image processing method and system with repetitive pattern detection

A method and apparatus for protecting access to audio and/or video data is accomplished when data is received, where the data may be audio data and/or video data. Having received the data, it is interpreted to determine whether an embedded data access parameter is active. If so, an indication of the particular type of data access is generated. The data access parameter may control access to the data as at least one of: copy restrictions, viewing restrictions, and/or use restrictions. The indication is subsequently provided to a computer system such that unauthorized accessing, including unauthorized copying, of the video and/or audio data is prohibited.

Method and apparatus for detecting protection of audio and video signals

A method and apparatus for interpolating image information obtains pixel information for a plurality of pixels surrounding a location of a pixel to be interpolated, whether the pixel is a missing pixel or an existing pixel whose color or intensity information is to be changed, and applies a gradient square tensor operation on a plurality of surrounding pixels to determine if the pixel to be interpolated is part of a geometric feature. If it is determined that the interpolated pixel is part of a geometric feature, such as a diagonal line or other suitable geometric feature, the method and apparatus uses pixel information from at least some of the surrounding pixels that are also determined to be the in geometric feature. This may be performed on a group of pixel basis and may include, for example, utilizing a block or kernel of pixels and a moving window of blocks of pixels to utilize the plurality of surrounding pixels.
