摘要： A broadcasting receiver and a power supply control method based on an operation mode are disclosed. Power supply is cut off to a data transmission/reception processing block corresponding to a mode, not determined as the operation mode. Therefore, it is possible to prevent unnecessary power consumption and lengthen the lifetime of the broadcasting receiver.

摘要： 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.

摘要： The HDTV receiver system includes a pre-detection processor to filter a digitized signal before detecting the sync signal. The pre-detection processor eliminates the effects of ghost signal which can cause distortion of the original sync signal. The pre-detection processor can be a tapped-delay-line filter, a blind mode equalizer, or both.

摘要： A Viterbi decoder for receiving and decoding a signal transmitted through a transmission channel in a vestigial side band (VSB) transmission system, in a high definition television (HDTV), which operates at the same speed as a symbol rate, can simply accomplish a hardware implementation using simplified memory system and a single decoder in order to restore an encoded signal, compared to the conventional art in which 12 decoders are used in restoring the encoded signal. Also, since the memory configuration thereof is regular, when it is intended to extend the observation sections, the memory structure can be extended easily. Moreover, the present invention can be adopted by extending easily to 3-bit 8 state or above as well as to 2-bit 4-state by means of a general Viterbi decoding algorithm.
