Description

Electronic device with TV signal switching function

The present invention relates to an electronic device having a television signal switching function.

Currently, TV sets used by users are generally classified into analog TVs and digital TVs. With the continuous development of digital television technology, many TV users have added digital antennas based on analog antennas.

The television of the prior art is generally a single antenna input port. In most cases, the digital signal and the analog signal are not in the same antenna. When the user wants to switch between the digital program and the analog program when watching the television program, the antenna must be manually replaced. It is very inconvenient to use, and it is also easy to cause the antenna to be damaged, and the connector of the antenna is loosened, thereby affecting the quality of the television signal.

Therefore, some existing television sets use a dual antenna input port to solve the problem of the user replacing the antenna. When adopting this technology, one antenna input port is fixed as an ATV (Analog Television) input port, and the other antenna input port is a DTV (Digital Television) input port, so that the user only needs to insert the ATV antenna and the DTV antenna. Go to the appropriate page. However, setting two or more antenna inputs on a TV set will inevitably occupy a certain space on the TV casing, which will affect the appearance of the TV. At the same time, two or more antennas will be used. When connected to a TV set, it also makes the cables appear messy.

In view of this, the present invention provides an electronic device having a television signal switching function to solve the above problems.

The antenna input port is connected to an antenna structure for receiving an analog television signal and a digital television signal transmitted by the antenna structure;

The control signal receiving unit is configured to receive a switching control signal of a switching analog television signal and a digital television signal sent by a control device; and

The switching unit is respectively connected to the antenna input port and the control signal receiving unit, and the switching unit switches the connection of the antenna input port to the analog television signal processing circuit or the connection with the digital television signal processing circuit according to the switching control signal. Thereby, the analog television signal or the digital television signal received by the antenna input port is transmitted to the corresponding television signal processing circuit for processing.

With the electronic device of the present invention, the user can simply control the switching of the analog program and the digital program by using the remote controller or pressing a button on the outer casing of the electronic device, without manually switching the antenna to switch, which can greatly improve the user's viewing.
