    摘要: A selector bank subsystem (SBS) of a code division multiple access (CDMA) system is disclosed, including two portions: a SBSC block and a S/V block. The one SBSC block is designed to manage twelve S/V boards so as to provide 96 traffic channels per SBS self, and thus, one S/V board provides eight communication channels. A selector bank subsystem (SBS) of a code division multiple access (CDMA) system, includes: an SBS block, the SBS block being composed of a pair of first processors for controlling the traffic frame communication with a CDMA interconnect subsystem (CIS) by selecting a channel between the CIS and a mobile service switch center (MSC); a dual port RAM (DRAM) for storing the traffic frame by the control of the first processor and being access-controlled by direct memory access controller (DMAC); a second processor for controlling the DMAC; an E1 interface portion for interfacing the frame data with the MSC by receiving synchronism from the TFU of the CPS receiver; and a S/V block being linked between the DRAM and the E1 interface as a plurality of extensible card forms, and for receiving the traffic frame to the E1 interface portion after DSP-processing. Therefore, the subsystem completes the SBS constitution of a mass-production module having competitiveness, avoids a complicated hardware constitution and reduces the possibility of a signal conflict between boards.

    摘要: An apparatus for reducing power consumption in a digital broadcast receiver is provided. An AC-to-DC converter converts input AC power into DC power that can be used in the receiver. A power control switch selectively supplies the DC power from the converter to a tuner unit and a decoder according to a command of a controller. The tuner unit receives broadcast channel signals and demodulates the received broadcast channel signals according to the respective broadcast formats. The decoder receives the demodulated broadcast signals from the tuner unit and decodes analog/digital broadcast signals. A multimedia output port is connected between the decoder and the display unit to transfer the audio/video output signals from the decoder to the display unit. The controller detects the state of the display unit through the multimedia output port to control whether to supply the DC power through the power control switch.
