Abstract
An apparatus for transmitting broadcasting content including a control signal in a broadcasting network, the apparatus includes: a modulator configured to modulate broadcasting content by a predetermined modulation method; a control signal generator configured to generate a control signal for remote control of infrastructure; an adder configured to add the control signal to the modulated broadcasting content; and a DTV transmitter configured to convert the added signal to a DTV broadcasting signal and transmit the DTV broadcasting signal.
Claims15
An apparatus for transmitting broadcasting content including a control signal in a broadcasting network, comprising:
- a modulator configured to modulate broadcasting content by a predetermined modulation method;
- a control signal generator configured to generate a control signal for remote control of infrastructure;
- an adder configured to add the control signal to the modulated broadcasting content;
- and
- a DTV transmitter configured to convert the added signal to a DTV broadcasting signal and transmit the DTV broadcasting signal.
An apparatus for receiving a control signal to control infrastructure, comprising:
- a DTV signal receiver configured to receive a DTV broadcasting signal including a control signal, tune and output a predetermined channel of the DTV broadcasting signal;
- a control signal extractor configured to extract only the control signal from the tuned signal;
- and
- a remote controller configured to provide the extracted control signal to a controller for controlling the infrastructure.
An apparatus for transmitting broadcasting content including a control signal in a broadcasting network, the apparatus comprising:
- a broadcasting content provider configured to receive broadcasting content and transform the broadcasting content to transport stream (TS) format;
- a control signal generator configured to generate the control signal having the TS format for controlling infrastructure;
- a TS multiplexer configured to receive and multiplex the broadcasting content and the control signal;
- and
- a broadcasting transmitting unit configured to modulate the multiplexed signal based on a predetermined method, convert the modulated signal to a digital television (DTV) broadcasting signal, and transmit the converted DTV broadcasting signal.
An apparatus for receiving a signal to control infra, comprising:
- a DTV signal receiver configured to receive a DTV broadcasting signal including a control signal, tune a predetermined channel of the DTV broadcasting signal, and demodulate the predetermined channel of the DTV broadcasting signal;
- a control signal extractor configured to demultiplex the demodulated signal by TS form and extract the control signal for controlling the infrastructure;
- and
- a remote controller configured to provide the control signal extracted in the extractor.
A system for controlling infrastructure by using a broadcasting network, comprising:
- a transmitter configured to modulate broadcasting content to be transmitted to the broadcasting network, add a control signal for controlling the infrastructure to the broadcasting content, convert the added signal to a DTV broadcasting signal, and transmit the DTV broadcasting signal;
- and
- a receiver configured to receive the broadcasting content including the control signal, tune a predetermined channel of the DTV broadcasting signal, extract only the control signal from the tuned signal, and provide the extracted control signal to a controller for controlling the infrastructure.
A system for controlling infrastructure by using a broadcasting network, comprising:
- a transmitter configured to receive broadcasting content, transform the broadcasting content to be transmitted as a transport stream (TS) format, generate the control signal for controlling the infrastructure as the TS format, multiplex the broadcasting content and the control signal, modulate the multiplexed signal based on a predetermined method, convert the modulated signal to a DTV broadcasting signal, and transmit the DTV broadcasting signal;
- and
- a receiver configured to receive DTV broadcasting signal, tune and demodulate a predetermined channel of the DTV broadcasting signal, demultiplex the demodulated signal into the broadcasting content and the control signal by TS form, extract the control signal for controlling the infrastructure, and provide the control signal to a controller for controlling the infrastructure.
