To facilitate understanding of the present embodiment, a detailed description is first provided below of a television tuning apparatus according to an embodiment of the present invention.
The first embodiment is as follows:

The signal processing module 10 is configured to receive a television signal, pre-process the television signal based on pre-stored control information, and output the pre-processed television signal; the television signals include 5G television signals and non-5G television signals; the signal input selector 20 is configured to send the preprocessed 5G television signal to the 5G processing module 30 in a 5G enabled state; the 5G processing module 30 is configured to perform 5G tuning processing on the preprocessed 5G television signal to obtain a 5G data packet.
Specifically, for the television signal received by the television tuner, the signal processing module 10 first pre-processes the television signal based on the pre-stored control information to obtain a pre-processed television signal, and then, when the signal input selector 20 is in the 5G enabled state, sends the pre-processed 5G television signal to the 5G processing module 30, so that the 5G processing module 30 performs 5G tuning processing on the pre-processed 5G television signal to obtain a 5G data packet. Therefore, the television tuning device can receive the 5G television signal without an external 5G receiving device, and perform tuning processing on the 5G television signal, so that the cost is reduced, and the user experience is improved.
The television tuning device provided by the embodiment of the invention comprises: the signal processing module, the signal input selector and the 5G processing module are connected in sequence; for 5G television signals in the preprocessed television signals output by the signal processing module, the signal input selector sends the preprocessed 5G television signals to the 5G processing module in a 5G enabling state, so that the 5G processing module performs 5G tuning processing on the preprocessed 5G television signals to obtain a 5G data packet, and therefore the 5G television signals can be received by a television without being externally connected with 5G receiving equipment, the cost is reduced, and the user experience is improved.
The control information may be pre-stored or manually set by a user according to actual application requirements, which is not limited in the embodiments of the present invention. The control information comprises a sampling frequency, a filtering parameter, a gain coefficient and a preset frequency segment; as shown in fig. 2, the signal processing module 10 further includes:

Specifically, after receiving a television signal, the signal processing module 10 may be a 5G television signal and/or a non-5G television signal; firstly, a sampling circuit 11 samples a television signal according to a pre-stored sampling frequency or a sampling frequency set by a user to obtain a first television signal; then, the filter circuit 12 performs filtering processing on the first television signal according to the filtering parameter to obtain a second television signal, and performs gain processing on the second television signal through the gain circuit 13 according to the gain coefficient to obtain a third television signal; finally, the separation circuit 14 separates the television signal corresponding to the preset frequency segment from the third television signal to obtain a preprocessed television signal. In addition, the signal processing module 10 further includes a power consumption control circuit (not shown) for controlling power consumption of the television signal, so as to implement preprocessing on the received television signal, and obtain a preprocessed television signal.

Further, as shown in fig. 3, the apparatus further includes: a non-5G processing module 40 connected to the signal input selector 20; at this time, the signal input selector 20 is further configured to send the preprocessed non-5G television signal to the non-5G processing module 40 when the non-5G processing module 40 is in an enabled state; the non-5G processing module 40 is configured to tune the preprocessed non-5G television signal to obtain a non-5G data packet.
In practical application, for a non-5G television signal in the preprocessed television signal output by the signal processing module 10, when the non-5G processing module 40 is in an enabled state, the signal input selector 20 further sends the preprocessed non-5G television signal to the non-5G processing module 40, so that the non-5G processing module 40 performs tuning processing on the preprocessed non-5G television signal to obtain a non-5G data packet. Therefore, the television tuning device provided in the embodiment of the present invention can simultaneously receive a 5G television signal and a non-5G television signal, and perform tuning processing on the processed 5G television signal and the processed non-5G television signal through the 5G processing module 30 and the non-5G processing module 40, respectively, to obtain a 5G data packet and a non-5G data packet, and perform display, thereby satisfying various requirements of a user and improving user experience.
On the basis of the foregoing embodiment, in order to implement the enabling states of the 5G processing module 30 and the non-5G processing module 40, the television tuning apparatus provided in the embodiment of the present invention further includes: a controller 50 connected to the 5G processing module 30 and the non-5G processing module 40, respectively; the controller 50 is configured to issue enable control information to the 5G processing module 30 and/or the non-5G processing module 40; so that the 5G processing module 30 and/or the non-5G processing module 40 set their own enable states based on the enable control information, respectively.
Specifically, when the main control board of the television receives control information input by a user, the control information is sent to the controller 50, and at this time, the controller 50 sends the control information to the signal processing module 10, so that the signal processing module 10 performs preprocessing on the received television signal according to the control information; meanwhile, the controller 50 also generates enable information according to the control information and transmits the enable information to the 5G processing module 30 and/or the non-5G processing module 40, so that the 5G processing module 30 and/or the non-5G processing module 40 set their own enable states based on the enable control information, respectively; for example, if the control information input by the user is 5G control information, at this time, the controller 50 sends the 5G control information to the signal processing module 10, so that the signal processing module 10 preprocesses the received 5G television signal according to the 5G control information, and generates 5G enable information, and sends the 5G enable information to the 5G processing module 30, so that the 5G processing module 30 sets its own enable state according to the 5G enable information, so that the signal input selector 20 sends the preprocessed 5G television signal to the 5G processing module 30, so that the 5G processing module 30 tunes the preprocessed 5G television signal; further, in the case where the control information input by the user is the 5G control information and the non-5G control information, the 5G control information generates the 5G enable information and the non-5G enable information to cause the 5G processing module 30 and the non-5G processing module 40 to set their own enable states, respectively, to cause the signal input selector 20 to transmit the preprocessed 5G television signal to the 5G processing module 30 and to transmit the preprocessed non-5G television signal to the non-5G processing module 40.
In addition, after the 5G processing module 30 and/or the non-5G processing module 40 set their own enable states, state information of setting success or setting failure is generated and fed back to the controller 50, so that the controller 50 monitors the states of the 5G processing module 30 and/or the non-5G processing module 40 in real time. In particular, in practical applications, in order to save space, the controller 50 may be disposed in the 5G processing module 30, or may be disposed in the television tuner separately, and the controller 50 may be an arm (advanced RISC machines) controller, or may be another controller or microcontroller, which is not limited in this embodiment of the present invention.
Further, the signal input selector 20 is a switch selection circuit, configured to turn on a communication connection line between the signal processing module 10 and the 5G processing module 30 when the 5G processing module 30 is in an enabled state; when the non-5G processing module is in the enabled state, the communication connection line between the signal processing module 10 and the non-5G processing module 40 is conducted.
Specifically, after the 5G processing module 30 and/or the non-5G processing module 40 set their own enable states according to the enable information of the controller, the switch selection circuit turns on the communication connection line between the signal processing module 10 and the 5G processing module 30 according to the enable state of the 5G processing module 30, so that the signal processing module 10 sends the preprocessed 5G tv signal to the 5G processing module 30; and/or, the communication connection line between the signal processing module 10 and the non-5G processing module 40 is turned on according to the enable state of the non-5G processing module 40, so that the signal processing module 10 sends the preprocessed non-5G television signal to the non-5G processing module 40.
At this time, the non-5G processing module 40 parses the received preprocessed non-5G television signal into non-5G packets that can be processed by the television demodulator, such as non-5G packets in TS (Transport Stream) format; the non-5G Television signals include DTMB (Digital Television Terrestrial Broadcasting) signals, ISDB (Integrated Service Digital Broadcasting) signals, ATSC (Advanced Television System Committee), DVB (Digital Video Broadcasting) signals, and the like.
As shown in fig. 4, the 5G processing module 30 may further include: a radio frequency integrated circuit 31 and a 5G multimode processing unit 32; the rf integrated circuit 31 is configured to perform rf processing on the preprocessed 5G television signal based on a signal type of the 5G television signal, and send the radio-frequency processed 5G television signal to the 5G multimode processing unit 32, so that the 5G multimode processing unit 32 performs encoding processing on the radio-frequency processed 5G television signal, and outputs an encoded 5G data packet.
In practical applications, the signal types of the 5G television signal include LTE (Long Term Evolution of universal mobile telecommunications technology), LTE-Advanced, 5GNR (5G New Radio), 5GSA (5G Stand Alone, 5G independent networking), 5GNSA (5G Non-Stand Alone, 5G dependent networking), mmWave (millimeter Wave), and so on, wherein, the radio frequency integrated circuit 31 is used for performing radio frequency processing on the LTE signal, the LTE-Advanced signal, the 5GNR signal, the 5GSA signal and the 5GNSA signal, and transmits the radio frequency-processed LTE signal, LTE-Advanced signal, 5GNR signal, 5GSA signal, and 5GNSA signal to the 5G multimode processing unit 32, so that the 5G multimode processing unit 32 performs encoding processing on the radio frequency-processed LTE signal, LTE-Advanced signal, 5GNR signal, 5GSA signal, and 5GNSA signal; and sending the mmWave signal to the 5G multimode processing unit 32, so that the 5G multimode processing unit 32 performs encoding processing on the mmWave signal to output an encoded 5G data packet.

Specifically, if the 5G television signal is a 5G video television signal, the 5G data packet output by the 5G processing module 30 is sent to the HDMI encoder 70, so that the HDMI encoder 70 encodes the 5G data packet into an HDMI signal and outputs the encoded 5G data packet; if the 5G tv signal is a non-5G video tv signal, the 5G data packet output by the 5G processing module 30 may be directly output through the HDMI encoder 70 at this time.
Therefore, in practical applications, as shown in fig. 3, if the 5G television signal is a non-5G video television signal, the signal output selector 60 may be connected to the 5G processing module 30 and the non-5G processing module 40 respectively to output the 5G data packet and/or the non-5G data packet. Furthermore, as shown in fig. 5, the signal output selector 60 may also be connected to the 5G processing module 30 through the HDMI encoder 70, and the 5G processing module 30 transmits the 5G data packet to the signal output selector 60 through the HDMI encoder 70, at this time, if the 5G television signal is a 5G video television signal, the HDMI encoder 70 also encodes the 5G data packet into an HDMI signal, and transmits the encoded 5G data packet to the signal output selector 60; if the 5G television signal is a non-5G video television signal, the HDMI encoder 70 directly transmits the 5G data packet output by the 5G processing module 30 to the signal output selector 60.
In addition, the user can also set the output mode of the signal output selector 60 through the main control panel of the television, for example, set the single-channel output of the signal output selector 60, at this time, the signal output selector 60 can only output 5G television signals or non-5G television signals at the same time; or, the signal output selector 60 is set to output two channels, and at this time, the signal output selector 60 can output a 5G television signal or a non-5G television signal at the same time, so that various requirements of a user are met, and the experience of the user is improved.
