A multimedia data transacting method, and an apparatus and system to perform the method, the method including extracting scrambled multimedia data from a broadcast signal received from a broadcasting station server, requesting and receiving a descramble key to descramble multimedia data, contained in the broadcast signal, that a user selects to purchase, and descrambling the selected multimedia data using the descramble key.
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.
摘要:
A high fidelity (Hi-Fi) audio signal recording/playback apparatus in which a Hi-Fi audio signal is recorded/reproduced using video heads without an extra Hi-Fi audio head. In the Hi-Fi audio signal recording/playback apparatus, the Hi-Fi audio signal is recorded and reproduced together with the video signal using the same 2-channel head and the same pre-amplifier, without an extra head and pre-amplifier for only a Hi-Fi audio signal, thereby markedly lowering the manufacturing cost.

摘要:
An audio apparatus, an audio signal transmission method, and an audio system are provided. The audio signal transmission method includes: wirelessly receiving an audio signal from a first external device; converting the received audio signal into audio signals of multi-channels; and wirelessly transmitting an audio signal of at least one of the multi-channels to at least one of second external devices. Therefore, the audio apparatus wirelessly communicates with a plurality of external devices, and thus a user can connect an audio device to an external device without using wired cables.
