The invention is directed to a broadcasting program recording system having a key input unit configured to receive a control signal from a user, the control signal including at least one of recording, reproducing, displaying and clipping signals, a display device configured to display a broadcasting program and a guide bar according to the control signal, respectively, a storage configured to store a broadcasting program, and a processor configured to control a broadcasting program to be recorded in the storage, control the recorded broadcasting program to be displayed on the display device, and control the guide bar to be displayed on the display device according to the control signal, respectively. The guide bar represents status information of the broadcasting program recorded in the storage or an ongoing status of a currently received broadcasting program, and the processor sets at least one clipping region on the guide bar according to the control signal and controls the at least one clipping region to be newly stored in the storage.

System and method for recording broadcasting programs

Disclosed is a method and apparatus embodying a flash translation layer (FTL) in a storage device including a flash memory. The FTL may classify a block into a sequential group and a fusion group based on a locality of a write request. The FTL may store data in blocks of the fusion group by using a page mapping scheme, and sequentially store data by using a block mapping scheme. The FTL may improve efficiency of garbage collection operation that is performed by using limited redundant blocks and also may increase efficiency of a non-sequential reference operation.

Variable space page mapping method and apparatus for flash memory device

A system and a method for recording digital broadcasting programs are disclosed. The system executes the clipping function that allows a user to select a portion of a recorded video signal, time-shifted video signal, or real-time broadcasting video signal through a guide bar in an OSD form, and stores only the video signal of the selected portion in an HDD. This prevents the HDD from being unnecessarily wasted and allows the user to easily perform the clipping function. Even a time-shifted program is stored in the HDD through the clipping function so that the user can reproduce the time-shifted program whenever he wants to watch it.

Digital TV system with a PVR function and method for making a stream jump therein, wherein, upon reception of a stream jump order from a user, searching the storage medium for a target GOP the user, or a system designated, changing a reproducing position to a TP next to a TP having a picture header among TPs in a prior picture positioned right forward of the searched target GOP, and starting reproduction from the changed reproducing position, thereby preventing occurrence of a decoding error while maintaining continuity of CC values in decoding TPs of a target GOP, to permit no broking of picture even in the stream jump.
