Abstract:
본 발명은 프로그램 타입의 우선순위에 따른 채널 자동 전환 방법 및 이를 이용하는 디지털 방송 수신기에 관한 것으로, 상기 채널 자동 전환 방법은 (A)상기 출력중인 디지털 방송에 해당하는 앙상블 내 다수의 디지털 방송을 각 디코딩하여 프로그램 타입을 포함한 채널 정보를 추출하여 저장하는 단계; (B)상기 다수의 디지털 방송의 프로그램 타입과 미리 설정된 프로그램 타입의 우선순위를 비교하여 우선순위를 결정하는 단계; 및 (C)상기 출력중인 디지털 방송의 프로그램 타입보다 우선순위가 더 높은 프로그램 타입이 존재하는지를 판단하여 더 높은 우선순위의 프로그램 타입의 디지털 방송의 채널정보를 독출하여 자동으로 채널을 전환하여 출력하는 단계를 포함함으로써, 사용자의 편의를 향상시키는 효과가 있다.
Abstract:
PURPOSE: A handover method of a digital broadcast receiver is provided to perform handover by using frequency information and to reduce handover time. CONSTITUTION: A digital broadcasting receiver monitors reception sensitivity(S111). If the reception sensitivity drops lower than reference sensitivity, the digital broadcasting receiver searches for a service identifier of a broadcasting signal that is received from a handover table(S113). The digital broadcast receiver measures the receive sensitivity about the searched frequency. The digital broadcast receiver fixes the searched frequency into servicing frequency(S117).
Abstract:
A terminal for sensing danger prepared by the present invention comprises a Doppler sensor unit which senses a Doppler frequency; a control unit which performs the determination on adjacent danger in order to generate control information using the received Doppler frequency from the Doppler sensor unit; a speaker unit which outputs danger of a user on a blind spot as a sound by the control information of the control unit; and a display unit which is to notify the user of the danger on the blind spot as an image or a text message by the control information of the control unit. [Reference numerals] (AA) Start;(BB) No;(CC) Yes;(DD) End;(S310) Start a danger detecting and alarming service;(S320) Sense nearby danger using a Doppler sensor unit;(S330) Is there any nearby danger to have been detected ?;(S340) Notice about the nearby danger
Abstract:
PURPOSE: A method for automatically changing a channel at IBOC(In-Band On-Channel) broadcasting system is provided to convert the preset digital channel and recover to the previous channel, thereby achieving the channel selection, acquisition and convenience enlargement of information. CONSTITUTION: A preset analog channel is reproduces by receiving an analog signal of IBOC(S100). Whether or not digital channel information exists in an analog receiving signal is determined(S200). Among a plurality of digital channels, Whether the presence of the set preference channel exists or not is determined(S400). If the prior channel exists, a it is divided and reproduced into priority channel(S510).
Abstract:
PURPOSE: A method for automatically changing a channel according to the priority of program types and a digital broadcast receiver using the same are provided to automatically search a digital broadcast service channel while a user watches a digital broadcast, thereby automatically changing a channel according to the priority of preset program types. CONSTITUTION: A controller(80) compares the program types of digital broadcasts with the priority of preset program types wherein the program types of digital broadcasts are extracted from a decoder. The controller determines the priority of the program types of the digital broadcasts. The controller determines whether a digital broadcast of a program type with a higher priority than the program type of an outputted digital broadcast exists. The controller reads channel information of the program type with the higher priority from a storage unit. The controller automatically changes a channel.
Abstract:
PURPOSE: An apparatus and a method for processing an audio per a program of a digital broadcast are provided to preset a sound effect proper for a program type, thereby automatically assigning a proper effect sound for an audio by a program. CONSTITUTION: A program type included in a transfer frame of a received signal of a digital broadcast is checked(S100). A sound effect filter is preset by a program type of a digital broadcast(S200). Application of a sound effect filter corresponding to the checked program is controlled. An audio signal among received signals of a digital broadcast is processed through an applied sound effect filter.
