Local digital television signal generator

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. Moreover, since the local digital TV signal generator can receive and store a digital TV signal which is currently broadcasting, various sources can be provided without a separate device. Also, the local digital TV signal generator may be acted as a digital VCR for home use depending on purpose of use, and may be acted as a digital DVD player if a title of a movie, for example, is provided from a DVD to adapt to the ATSC transport standards.
