Specifically, the control terminal of the present embodiment is installed in an indoor living room, has at least two HDMI connectors 4 and one cable interface 3, and further has an infrared transceiver sensor, and is connected to an external network modem through the cable interface 3, so that network data can be received. Then, the television is connected with an external television through one of the HDMI connectors 4, and the volume is adjusted to the maximum when the television is switched to a corresponding signal connector input mode after being turned on.

At this time, the operation interface built in the control terminal is displayed on the television, preliminary setting is carried out through remote control, such as networking setting, volume and other system conventional setting, and then the television enters a TV interface or a video-on-demand interface for watching.

Meanwhile, another HDMI connector 4 of the control terminal in this embodiment is further connected to another content source providing device, specifically, a blu-ray player, and the blu-ray player is always in an on state. At the moment, a user can exit to an operation interface through remote control, and then directly switches signals to input signals of the blue-ray player into the television.

Then can realize through above-mentioned mode that single control terminal carries out the function that switches to different signal sources, and equipment integration is higher, does benefit to arrange and walks the line, need not to change a plurality of remote controllers, provides more convenient control mode.

Example 2:

in this embodiment, optimization and limitation are performed on the basis of embodiment 1, wherein a bluetooth connection module is further disposed in the control terminal, and the remote controller directly interacts with the control terminal in an infrared manner. And the control terminal is in control connection with the blue-ray player through the Bluetooth connection module.

Because the blue-ray player is connected with the control terminal only through the data line of the HDMI, the data line can only transmit video data, but cannot realize control signal transmission, the blue-ray player is directly connected with the blue-ray player through the Bluetooth connection module in a control mode, and a control program is preset, so that the remote controller is matched with the control logic of the blue-ray player in an adaptive mode.

And when the blue-ray player is used, the blue-ray player is directly controlled to be started on the operation interface through the remote controller of the control terminal, then the input operation interface of the blue-ray player is switched, and the blue-ray player is controlled through the remote controller.

And the metal corrugated pipe is internally provided with an optical channel, so that certain emission loss can be kept under the state of not exceeding the maximum bending limit.

The control terminal in the embodiment is connected with a plurality of devices, and the television is an old-fashioned A/V interface, cannot receive wireless signals and can only be controlled by simulating infrared emission signals. The infrared control module in this embodiment stores the control codes of most electronic devices on the market, and after the infrared control module is connected with the corresponding device, the infrared control module can be debugged by an external connection computer and written into the corresponding code library, so that when the remote controller sends a corresponding instruction, the infrared control module can transcode the code into a corresponding signal to send the signal.

The control terminal in this embodiment is also connected with a blu-ray player through HDMI, and the blu-ray player is controlled by an infrared remote controller. When the system is set, an external computer is firstly written in corresponding control codes of the television and the blue-ray player, and then the head of the optical splitter is aligned to the television and the blue-ray player during debugging. The two devices can be simultaneously standby and operated by the user operating the remote controller of the control terminal.

It should be noted that only the blu-ray player is taken as an example in this embodiment, and those skilled in the art should recognize that the device may be equally replaced by any content source providing device with an HDMI data transceiving function, such as a game host, a computer host, a tablet computer, or a camera and monitor camera.
