Digital Broadcasting Transmitter/Receiver for fast channel changing

1. Technical Field of the invention defined in the claims The present invention relates to a digital broadcast reception apparatus will be about the digital multimedia broadcasting receiving device, in particular to allow for fast channel switching by reducing the PSI parsing time. 2. The invention attempts to solve the technical challenges The present invention is a (Packet identifier) ​​PID information for the entire channels in a transmitting end of digital broadcasting using the characteristic to which the digital broadcast stream, PID of the broadcasting company is kept constant in order to eliminate the long-channel conversion time of the DTV disadvantages compared to an analog TV to provide a digital broadcasting transmission and reception apparatus for rapid channel change to transmission by including in each channel TS that purpose. 3. Resolution of the subject matter of the invention, The present invention, in the digital broadcasting transmission apparatus for rapid channel change, A / V stream of a predetermined channel; PSI generation unit generating a (Program Specific Information) information PSI of the A / V stream; PSI length detection unit for detecting a length of the PSI generated by the PSI information generation unit; CI information generator for generating (Channel Information) CI information including PSI information of all digital broadcasting channels input to the digital broadcasting transmission apparatus; The PSI to the PSI information transmission area generated by the generator according to the length information detected by the PSI length detection unit dividing the CI generated by the CI information generating unit is inserted in stock CI insertion unit; And also it includes a TS multiplexer for transmission to multiplexing the A / V stream and an output of the CI insertion unit. 4. An important use of the invention, The invention yiyongdoem etc digital broadcast system. DTV, PSI (Program Specific Information), DMB, CI
