A digital broadcasting device is provided to be easily installed structurally, simplify wirings of transmission, reduce a maintenance cost and to convert an analog signal into a digital signal. An analog/digital converter converts an analog video/audio signal of data inputted from an analog broadcast data recording and relaying unit into digital information. A video/audio mixing unit mixes the digital video/audio information with a signal of a digital data converter. A data compressing unit compresses the mixed signal. A temporary storage unit stores the compressed signal. A digital transmission unit keeps the signal, which has been stored in the storage unit, in a data keeping unit, transmits it via a network transmission controller or transmits it to a network via the network transmission controller from the temporary storage unit. A network reception controller receives the signal transmitted through the network transmission controller via the network. An STB(Set-Top Box) outputs the signal received by the network reception controller to an image/voice output unit via an image/voice output unit remote controller. A video recording/relaying unit is connected with the digital transmission unit via the network and controls an external camera via a camera controller to record video. The camera converts the recorded signals into digital signals and transmits the signals to the network via the network transmission controller. |
