摘要： Disclosed is a digital entertainment system which can receive, store and reproduce multimedia data such as broadcasts, provide diverse communication interfaces, and exchange and share data with external appliances connected thereto. In the network printer control system, an audio and video (A/V) signal processing part receives external broadcasting signals, and outputs digital data obtained through a process of channel selection and demodulation of the broadcasting signal. A data over cable service interface specification (DOCSIS) and out of band (OOB) processing part provides a communication interface according to a DOCSIS standard and for an OOB service. An MPEG processing part generates standard video signals by decoding input data by a predetermined method, and outputs the generated standard video signals to any external appliances, and a system bus communicably connects the signal processing part, the DOCSIS/OOB processing part and the MPEG processing part. A control part, communicably connected to the system bus, controls an operation of the A/V signal processing part and the MPEG processing part and performs a communication through the DOCSIS and OOB processing part.
