摘要:
A broadband multi-phase output delay locked loop (DLL) circuit can be operated in a wide range of frequencies and generate various phases. Unlike conventional voltage control delay lines in which delay cells are connected in series, the DLL circuit utilizes a delay matrix in which a resistant network is used so that the number of delay cells connected in series is reduced, various phases can be outputted, and a delay interval error (phase error) due to the resistant network is minimized. The current of the delay cells is controlled so that the delay cells in the delay matrix can operate in a wide range of frequencies, and load capacitance values of capacitors connected in parallel in the delay cells can be controlled.

A wireless communication system and method. The wireless communication system includes a transmission device and a reception device. The transmission device includes a wireless communication part connected to the reception device by wireless, a storage part for storing a first information set when the wireless connection is off and a second information set when the wireless connection is on, a receiver for receiving a control signal requesting a certain function output from a user interface, when the wireless connection is off, and a controller for performing a function corresponding to the received control signal if the control signal is received from the user interface when the wireless connection is off, and for controlling the storage part to store the first information that is set according to the performed function. When the wireless connection is turned off, the transmission device performs functions as a set-top box, and the auto program function is executed more rapidly.
摘要:
A wireless transmitting and/or receiving system and method of sharing analog information between a transmitter and a receiver connected to the transmitter by a wireless channel. The wireless transmitting and/or receiving system includes a transmitter that extracts analog signal and information from an analog broadcast signal, converts the analog signal into a transport stream that is then sent to a first wireless channel, transmits the analog information to a second wireless channel when the analog information is extracted, and updates previously stored first analog information with the received analog information, and a receiver that decodes the transport stream received from the transmitting means via the first wireless channel and updates previously stored second analog information with the analog information received by the second wireless channel.

An image providing system and a method thereof, wherein the image providing system includes a host device for receiving video signals from video input sources and for processing the received video signals, a wireless display device, connected wirelessly to the host device, for displaying an image corresponding to a first of the processed video signals if the first video signal is received, and a wire-based display device, connected by wire to the host device, for displaying an image corresponding to a second of the processed video signals that is different from the first video signal if the second video signal is received. Accordingly, many users can view different images using a plurality of display devices of one image providing system.

Disclosed are an image processing system for displaying character information and a method for the same. According to the image processing system, character information is input by a user, and the input character information is combined with received image and audio signals to generate Transport Streams (TSs), which are transmitted to an image display. The image display decodes and outputs the received TSs. Accordingly, when it is necessary to inform urgent public notices within a predetermined region such as a public place, these notices may be rapidly transmitted to be displayed as character information.
摘要:
A frame transmission method performed by a transmitting end in a video reproduction system having the transmitting end for wirelessly transmitting frames and a receiving end for receiving the frames transmitted from the transmitting end and reproducing a video signal. The transmitting end receives information about a state of a wireless environment from the receiving end, determines the frames to be transmitted to the receiving end in consideration of the received information about the wireless environment state, and transmits the determined frames to the receiving end. The receiving end measures the state of the wireless environment by judging whether an error exists in the received frames and transmits the measured state of the wireless environment to the transmitting end. Accordingly, different frames can be transmitted according to the state of the wireless environment.
