Abstract: Embodiments of the present invention provide an edge adaptive spatial temporal deinterlacing filter that evaluates multiple edge angles and groups them into left-edge and right-edge groups for reconstructing desired pixel values. A leading edge is selected from each group, forming the final three edges (left, right and vertical) to be determined. Spatial temporal filtering is applied along the edge directions.

Abstract: In a television receiving apparatus, a receiving apparatus 1 has storage means for storing a voice output switching table 20 registering a voice setting record 21 having the voice output format associated with the broadcasting language of the received digital broadcasting in a control unit 2. Every time the switching operation of the voice output format is made, the voice setting record 21 is selected in the registered order. Also, the receiving apparatus 1 outputs a voice signal with the language and the voice output format based on the selected voice setting record 21 from an output portion 6. Accordingly, the broadcasting language and the voice output format of the digital broadcasting being received can be switched by single operation, resulting in enhanced operability.

Abstract: A method and computer program product for reformatting at least a portion of a digital source image. The digital source image has a number of pixels defining an original format which is to be converted to a destination image in a new format having a number of pixels. The number of pixels of the new format is greater than the number of pixels in the original format. A gradient is estimated at a point within a window which encompasses a plurality of intensity values from the source image. A polynomial is then used to determine a value for the point in the new format within the window. The polynomial is based in part upon the gradient. Values are then determined for additional points in the destination image by selecting a new window and repeating the acts of estimating a gradient and using a polynomial to determine a value.
