Abstract: Provided are an apparatus and a method to compress an image through a frame prediction. By analyzing a video signal, a similarity rate between a frame at a coding time and a previous input frame is compared with a reference similarity rate, respectively. When the similarity rate between the frame at the coding time and the previous input frame is equal to or greater than the reference similarity rate, the frame at the coding time is compressed using a frame vector including an identification information about a reference frame similar to the frame at the coding time. When the similarity rate between the frame at the coding time and the previous input frame is less than the reference similarity rate, the frame at the coding time is compressed through an intra or inter coding scheme.

Abstract: Disclosed is an apparatus for identifying the authenticity of a holographic image which can identify the authenticity by comparing a holographic image displayed by emitting light with an identical characteristic to an emitting characteristic of a first reference wave used when the holographic image was created with an original image. As a result, when a hologram is made, an image or a pattern is recorded by using a reference wave at a particular angle and on a particular laser waveband. Therefore, the hologram cannot be easily duplicated or copied to forge.

Abstract: The present invention relates to a method and an apparatus for efficiently transmitting a conditional access message, which enable a conditional access to a broadcasting service in a DMB system. A terrestrial DMB transmitting system which supports a conditional access includes: a conditional access system (CAS) server which generates information about the transmission cycle and traffic of an entitlement control message (ECM) related to the reception authority of a DMB service; a DMB video scrambler which calculates the number of streams necessary for transmitting the ECM based on the information about the transmission cycle and traffic of the ECM; and a DMB video encoder which generates null packets as many as the calculated number of the streams. The DMB video scrambler generates an ECM packet by inserting the ECM into a payload which is arranged in transport streams for the null packets.
