Abstract: A method for transmitting broadcast and a data stream in a hybrid fiber coax (HFC) based cable network according to the present invention comprises: a first transmission step in which a broadcast transmitting device transmits the broadcast and a data service stream in an internet protocol (IP) based stream or radio frequency (RF) signal form through an optical section toward a cell node, which is a contact point between an optical section and a cable section of the cable network; and a second transmission step in which the cell node converts the broadcast and the data service stream into an RF signal, an IP-based stream, or an RF/IP fusion service stream according to a service type of a subscriber terminal, and transmits the converted result to a user terminal through the cable section. Thus, a cell unit, which is a coaxial section subscriber group, only exchanges and transmits a broadcast service stream, which is actually watched, such that broadcast frequency bands, which are to be transmitted simultaneously irrespective of whether they are watched or not, can be efficiently used.

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.
