Abstract: A method and an apparatus for calculating source image coordinates. In an embodiment, a variation rate of the source image coordinate with respect to a converted image coordinate is calculated by a recursive computation, and variation rates are accumulated to obtain the source image coordinate. Because the converted image coordinate sequentially increases one-by-one, the variation rate may be obtained by using adding operations of previously obtained source image coordinate, rather than multiplying operations with the all of the converted image coordinates. Therefore, the source image coordinates may simply and effectively be calculated.

Abstract: Provided are a receiver with a CA function based on software download, a CA system including the receiver, and a method for managing CA software executed by the receiver. The receiver includes a CA software management means, a download means, a demultiplexer, and a descrambler. The CA software management means performs an overall management operation including the download, execution, state control and termination of a plurality of CA softwares. The download means downloads the CA software from a CA software download server at the request of the CA software management means. The demultiplexer receives scrambled multimedia contents and a CA message and transfers the CA message to the CA software management means. The descrambler receives a descrambling key extracted from the CA message by means of the CA software and descrambles the scrambled multimedia contents with the descrambling key. Thus, a plurality of CA softwares can be operated in one receiver (e.g., a settop box).
