摘要： A method for controlling reception of an audio specialty channel is provided to decode and process only audio signals when an audio specialty channel is selected, and output the processed audio with a background image preliminarily stored in a digital broadcasting receiver or video received and processed through other tuners. A microcomputer controls a tuner for selecting a random broadcasting channel(S10). The microcomputer checks whether the selected broadcasting channel is an audio specialty channel(S11). If the selected broadcasting channel is not an audio specialty channel, an audio decoder and a video decoder are enabled to normally perform decoding and signal processing of audio and video(S12). The processed audio and video are displayed through an external device(S13). If the selected broadcasting channel is an audio specialty channel, the audio decoder is enabled to perform decoding and signal processing of audio while disabling the video decoder not to perform decoding and signal processing of video(S14,S15). The microcomputer reads out and reproduces a background image which is preliminarily stored in a memory, and displays the background image with outputting the audio(S16,S17).

摘要： An audio mute control device for a digital broadcasting receiver and a method thereof are provided to prevent audio data from being disconnected to an external connection device connected to the digital broadcasting receiver by blocking an audio output and simultaneously generating and outputting audio null data when it is necessary to perform audio mute operation. A microcomputer(16) monitors audio mute operation. An audio null data generator(19) generates audio mute data under the control of the microcomputer(16). An HDMI(High-Definition Multimedia Interface) transmitter(18) transmits the audio mute data generated in the audio null data generator(19) to an external connection device. The audio null data generator(19), which is a decoder, creates audio null data based on the audio mute control operation form the microcomputer.

摘要： A method and an apparatus for reproducing recorded image data at the receiving time of abnormal broadcasting are provided to allow viewers to watch normal image data even when the signal intensity is weak or an abnormal signal is received. A digital broadcasting receiver receives a digital broadcasting signal and selects a channel according to selection of a user(S302). A main controller measures the signal intensity of the digital broadcasting signal(S304). The main controller extracts the pre-stored image data and outputs the image data when the signal intensity is weak or abnormal(S308). The main controller terminates the output of the image data and normally outputs the digital broadcasting signal(S312) when the signal intensity is strong and normal.

摘要： A method and an apparatus for editing the channel numbers by the program categories are provided to easily record a specific image by a simple manipulation without searching channels one by one. When a broadcasting signal including channel information is transmitted from a broadcasting station, a set top box receives the channel information together with the broadcasting signal(S302). A control member analyzes a channel on the basis of the channel ID(IDentification), classifies the channel numbers and ID values by genres and stores the classified data by categories(S304). When the character number 1 key corresponding to a sport category is inputted by a user(S306). Thereafter, the control member sequentially displays the channel numbers of the sport category(S308). Thereafter, when a desired channel is selected(S310), the broadcasting image corresponding to the channel is displayed(S312).

摘要： A software upgrade method of an AV device is provided to perform software upgrade for the AV device through received OTA software if an OTA software version is an upper version than a software version of the AV device. If an AV(Audio/Video) deice is connected to a host device supporting an HDMI(High Definition Multimedia Interface), the host device parses an EDID(Extended Display Identification Data) of the AV device through an HDMI CEC(Consumer Electronics Control) and stores AV device information in a memory(S10,S11). An OTA(Over The Air) software included in service information of a received broadcasting signal is detected(S12). The OTA software is temporarily stored in a flash memory. A software version of the AV device stored in the memory is compared with a version of the received OTA software to confirm whether the OTA software version is a higher version than the stored software version of the AV device(S13,S14). If so, a general software upgrade operation for the AV device is performed by reading the OTA software temporarily stored in the flash memory(S16).
摘要翻译：提供AV设备的软件升级方法，如果OTA软件版本比AV设备的软件版本高，则通过接收的OTA软件对AV设备执行软件升级。如果AV（音频/视频）设备连接到支持HDMI（高清多媒体接口）的主机设备，则主机设备通过HDMI CEC（消费电子控制）解析AV设备的EDID（扩展显示标识数据）并将AV设备信息存储在存储器中（S10，S11）。检测到包括在接收到的广播信号的服务信息中的OTA（空中）软件（S12）。 OTA软件暂时存储在闪存中。将存储在存储器中的AV设备的软件版本与所接收的OTA软件的版本进行比较，以确认OTA软件版本是否高于存储的AV设备的软件版本（S13，S14）。如果是，则通过读取临时存储在闪存中的OTA软件来执行AV设备的通用软件升级操作（S16）。
