Abstract: A serial transmission system for sharing a plurality of differential lanes is provided to reduce the number of differential lanes and power consumption in a portable multimedia terminal by adjusting a bandwidth of the reception devices according to a total bandwidth of the differential lanes. A transmission bridge(20) transmits data to a plurality of transmission devices(10) through a plurality of differential lanes(30) by packeting the data received from a plurality of transmission devices, distributing a packet to each differential lane, and serializing the distributed packet. A receiving bridge(40) transfers the data to each reception device(50) by parallelizing the packet received from the transmission bridge through the differential lanes, extracting the data from the paralleled packets, and distributing the data to each reception device. The packet includes ID information informing the receiving bridge of the reception device to receive the data extracted from the packet. The transmission bridge includes a transmission protocol layer(21), a transmission physical layer(22), and a bandwidth controller(23).

Abstract: A method for detecting the connection of a cable and a method for controlling the output of a portable terminal are provided to shut off the output of an embedded display and allow only an external output automatically so that power consumption is reduced. The connection of a cable and a portable terminal is detected(S100). An external output signal becomes in an off state and the power of a display embedded in the portable terminal is turned on if the cable is not connected(S120,S130). The display is turned off, and a signal is transmitted to the cable if the cable is connected. The power state of the portable terminal is checked frequently or periodically(S160). The connection of the cable is detected by using a hot plug detect(HPD), embedding a switch in a jack, or using a ground path.

Abstract: A memory unit for implementing a serial data transmission is provided to transmit smoothly data even in case that the number of lanes in a transmitting end is not the same as that in a receiving end. A memory unit for implementing a serial data transmission comprises the first routing table(312), the first multiplexer(314), a memory(330), the second multiplexer(324), and the second routing table(322). The first routing table(312) receives and collects data from a physical layer where lanes are seamlessly connected at a transmitting end and a receiving end. The first multiplexer(314) distributes the data collected via the first routing table(312) and switches an operation state of the memory unit to the transmitting end or the receiving end according to a transmission or a receipt state of the data. The memory(330) stores the data transmitted via the first multiplexer(312). The second multiplexer(324), connected to the memory(330), extracts the data from the memory(330) and switches the operation state of the memory unit to the transmitting end or the receiving end according to transmission or a receipt state of the data. The second routing table(322) collects the data transmitted via the second multiplexer(324) and transmits the data to a physical layer where lanes are seamlessly connected at a transmitting end and a receiving end.

Abstract: An intelligent multimode apparatus and a realization method thereof are provided to form a conversion switch unit and a sensing unit additionally in a multimode terminal to use an unused frequency band effectively, thereby improving data transmission speed and performance. A wideband antenna(100) transceives various frequency bands of signals. An RF(Radio Frequency) receiving end(200) separates signals transceived through the antenna(100) according to frequency bands, and inputs/outputs the separated signals. A baseband unit(300) performs modulation and demodulation in accordance with at least one wireless communication standard. A conversion switch unit(500) selectively establishes a signal delivery path between the receiving end(200) and the baseband unit(300). A main processor(600) classifies and processes the signals inputted/outputted through the baseband unit(300). A sensing unit(400) periodically senses unused frequency bands to transmit width and unused time of the unused frequency bands to the main processor(600).
