  • Patent number: 7051325
    Abstract: An apparatus and method for upgrading a software, including a version comparing unit for comparing a version of a software code and a version of a previously installed software code to determine a newer version and an upgrade processing unit for installing the software by abstracting software data in the software code, can automatically install an upgraded system software in a corresponding apparatus for receiving digital broadcasting by detecting the code of the system software simultaneously included in an advertisement broadcasting and an advertisement broadcasting signal.

  • Patent number: 6738102
    Abstract: A local digital TV signal generator is disclosed, which generates an ATSC RF signal that can be received by a digital TV. Synchronization between a memory device and a VSB remodulator is performed through a controller, and data conversion adapted to the VSB modulator is performed so that streams of ATSC standards are read out from MPEG streams stored in the memory device, thereby outputting an RF signal. Accordingly, the local digital TV signal generator has the low cost and a small volume to facilitate movement as compared with the related art. Since the local digital TV signal generator is mounted inside or outside the PC and implemented using an operating system (O/S) for PC, it is simple and easy in installation and use. Furthermore, since the streams stored in the memory device can be reduced without an external device, it is useful in view of aspects such as mobility, economical efficiency, and maintenance.
