Method and system for receiving digital broadcasting by using mobile communication terminal
View Patent ↗Disclosed is a system and a method for receiving digital broadcasts by using a mobile communication terminal. The system includes a digital broadcast receiving device for receiving digital data from a contents provision unit by using a wired/wireless communication network and transmitting the digital data; and a mobile communication terminal for receiving the digital data from the digital broadcast receiving device, decoding the digital data, creating video and audio signals, and outputting the video and audio signals. The mobile communication terminal replaces circuits of the digital broadcast receiving device, which are in charge of predetermined functions. This simplifies the construction of the digital broadcast receiving device and reduces the cost for implementing the device.
1. A mobile communications terminal for receiving and outputting digital data for digital broadcast receiving device, the digital broadcast receiving device receiving the digital data from the contents provision unit by using the wired or wireless communication network and transmitting the digital data to the mobile communication terminal, the mobile communication terminal comprising:
a terminal communication unit configured to be connected to the digital broadcast via a digital broadcast receiving device and receive the digital data from the digital broadcast receiving device;
a terminal input unit for receiving a command or data for controlling the mobile communication terminal from a user and also receiving another command or data for watching the digital broadcasts instead of the digital broadcast receiving device;
a terminal storage unit for controlling data and signals of the mobile communications terminal, identifying whether the mobile communication terminal and the digital broadcast receiving device are connected to each other and making the mobile communication terminal enter into standby mode for communicating with the digital broadcasting receiving device;
a terminal decoding unit for decoding the digital data to thereby create video and audio signals without process in the digital broadcast receiving device; and
a terminal output unit for outputting the video and audio signals.
2. A method for receiving and reproducing digital data for digital broadcasts provided from a contents provision unit by using a wired or wireless communication network, a digital broadcast receiving device, and a mobile communication terminal, the method comprising:
connecting the digital broadcast receiving device to the mobile communication terminal so that the digital broadcast receiving device and the mobile communication terminal enter into a standby mode for communicating with each other;
receiving the digital data from the digital broadcast receiving device at the mobile communication terminal, when the digital broadcast receiving device receives the digital data from the contents provision unit via the wired/wireless communication network, and also receiving another command or data for watching the digital broadcasts instead of the digital broadcast receiving device;
storing the digital data received from the contents provision unit via the digital broadcast receiving device in a memory of the mobile communication terminal instead of the digital broadcast receiving device;
decoding the digital data to thereby create video and audio signals at a decoding unit of the mobile communication terminal without decoding process in the digital broadcast receiving device; and
reproducing the video and audio signals at the mobile communication terminal.
