Detailed Description
The application aims to provide a wireless transmitting system, a wireless transmitting method and a television, which can effectively avoid the problem of frequency interference between a wireless transmitting module and a DTV receiving module.
In order to make the objects, technical solutions and effects of the present application clearer and more specific, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Referring to fig. 1, the wireless transmission system provided by the present application includes a DTV receiving module 11 and a wireless transmitting module 12; the wireless transmitting module 12 is connected to the DTV receiving module 11, and the DTV receiving module 11 is configured to receive DTV signals. The DTV signal is provided with a plurality of channels, and the corresponding frequency of the currently played channel is a first frequency; the transmitting frequency of the wireless transmitting module 12 is the second frequency, and the first frequency is different from the second frequency, that is, the frequencies of the DTV receiving module 11 and the wireless transmitting module 12 are different, so that interference between the frequencies of the wireless transmitting module 12 and the DTV receiving module 11 can be avoided, and the DTV receiving module 11 can effectively receive the DTV signal.
In some embodiments, the wireless transmitting module 12 is configured to transmit signals in the UHF band, and the DTV signal of the DTV receiving module 11 is in the same band as the UHF band, so as to avoid interference of the transmitting frequency of the wireless transmitting module 12 to the DTV signal of the DTV receiving module 11, the transmitting frequency of the wireless transmitting module 12 is a second frequency, and the second frequency is different from the first frequency of the currently played channel of the DTV signal.
In specific implementation, the DTV receiving module 11 recognizes the first frequency of the currently played channel of the DTV signal, acquires the first frequency, outputs the first frequency to the wireless transmitting module 12, and the wireless transmitting module 12 determines whether the current frequency is the same as the first frequency according to the first frequency, if the first frequency is the same as the current frequency, the current frequency is adjusted to the second frequency, and is further staggered from the first frequency of the currently played channel, so as to avoid the same-frequency interference problem between the wireless transmitting module 12 and the DTV receiving module 11.
As one example, when the current frequency of the wireless transmitting module 12 is close to the first frequency, the wireless transmitting module 12 adjusts the current frequency to the second frequency; at this time, the difference between the first frequency and the second frequency is not smaller than the safety threshold frequency value. It should be noted that the safety threshold frequency value refers to a minimum frequency difference between two signals, where no frequency interference occurs. That is, when the current frequency of the wireless transmitting module 12 and the first frequency are not different from each other by the safety threshold frequency value, the DTV receiving module 11 will also interfere with the reception of the DTV signal, so that the first frequency and the second frequency are staggered by at least one safety threshold frequency value, and the problem of near-frequency interference between the wireless transmitting module 12 and the DTV receiving module 11 can be avoided.
In some embodiments, referring to fig. 2, the dtv receiving module 11 includes a tuner 111 and a demodulation chip 112, and the demodulation chip 112 is connected to the tuner 111. The tuner 111 is configured to receive a DTV signal, and may perform functions of frequency selection, amplification, and frequency reduction of the DTV signal, frequency-reduce the received DTV signal, and output an intermediate frequency signal to the demodulation chip 112, where the demodulation chip 112 decodes the DTV signal and outputs an audio/video signal.
As an embodiment, DTV receiving module 11 further includes a main chip 113, main chip 113 being connected to tuner 111 and demodulation chip 112, respectively. When the demodulation chip 112 performs channel demodulation and channel decoding on the DTV signal, a transport stream is output to the main chip 113, and the main chip 113 multiplexes and decodes the transport stream and then outputs an audio/video signal. The main chip 113 is further configured to switch a currently played channel of the DTV signal, and acquire, in real time, a corresponding frequency of the currently played channel of the DTV signal received by the tuner 111, so as to provide a reference basis for frequency adjustment of the subsequent wireless receiving module 13.
As an embodiment, the DTV receiving module 11 is connected to the wireless receiving module 13 through the main chip 113, and the main chip 113 outputs the acquired first frequency to the wireless receiving module 13 and outputs the audio/video signal to the wireless transmitting module 12. The signal transmission between the main chip 113 and the wireless receiving module 13 may be implemented through an I2C bus or a USB channel, which is not particularly limited in the present application.
In some embodiments, the wireless receiving module 13 compares the first frequency with the current frequency when receiving the first frequency output by the main chip 113, and adjusts the current frequency to the second frequency when the first frequency is the same as or similar to the current frequency. Specifically, since the wireless transmitting module 12 is for transmitting signals in the UHF band, i.e., the current frequency itself is in the UHF band. In order to stagger the transmission frequency of the wireless transmission module 12 from the first frequency, the wireless transmission module 12 calculates a safe frequency range from the first frequency, the safe frequency range including a first interval and a second interval. The upper limit value of the first interval is the difference value between the first frequency and the safety threshold frequency value, and the lower limit value of the first interval is the lower limit value of the UHF frequency band; the lower limit value of the second interval is the sum value of the first frequency and the safety threshold frequency value, and the upper limit value of the second frequency is the upper limit value of the UHF frequency band. After the wireless transmitting module 12 calculates the safe frequency range according to the first frequency, the current frequency is selected to be adjusted to the first interval or the second interval, and when the current frequency is specifically selected, the current frequency can be adjusted according to which interval is closer to the first interval, which is not limited in the application.
For example, if the UFH frequency band is 470MHZ to 900MHZ, the safety threshold frequency value is ase:Sub>A, and the first frequency is B, then the first interval is 470MHZ to (B-ase:Sub>A), and the second interval is (b+ase:Sub>A) to 900MHZ, where the safety threshold frequency value ase:Sub>A may be 40MHZ, and the second frequency is within the first interval or the second interval, thereby ensuring that the second frequency differs from the first frequency by at least the safety threshold frequency value, and further avoiding the same frequency or near frequency interference between the wireless transmitting module 12 and the DTV receiving module 11.
In some embodiments, referring to fig. 3, the wireless transmission system further includes a wireless receiving module 13, where the wireless receiving module 13 is communicatively connected to the wireless transmitting module 12, and the wireless receiving module 13 is configured to receive a signal sent by the wireless transmitting module 12. The wireless transmitting module 12 adjusts the transmitting frequency according to the first frequency, performs frequency matching with the wireless receiving module 13, and transmits a signal at the second frequency after the frequency matching is successful. Specifically, the wireless transmitting module 12 modulates an audio signal or a video signal of the received audio-video signals onto a radio frequency carrier, and then transmits the modulated audio signal or the modulated video signal through a wireless signal of a second frequency, which is received by the wireless receiving module 13.
As an embodiment, referring to fig. 4, the wireless transmitting system further includes an audio output module 14, where the audio output module 14 is connected to the wireless receiving module 13. When the wireless transmitting module 12 modulates the audio signal, it sends the audio signal to the wireless receiving module 13, the wireless receiving module 13 demodulates and decodes the received signal to restore the audio signal, and sends the audio signal to the audio output module 14, and the audio output module 14 plays the sound.
As another embodiment, referring to fig. 5, the wireless transmitting module 12 further includes a display module 15, where the display module 15 is connected to the wireless receiving module 13. When the wireless transmitting module 12 transmits the modulated video signal to the wireless receiving module 13, the wireless receiving module 13 demodulates and decodes the received signal to restore the video signal, and transmits the video signal to the display module 15, and the display module 15 displays the image information corresponding to the video signal.

And then the first frequency is sent to a wireless transmitting module, the wireless transmitting module calculates a safe frequency range according to the first frequency, judges whether the current frequency is in the safe frequency range, and adjusts the current frequency to a second frequency if the current frequency is not in the safe frequency range. And then the wireless transmitting module and the wireless receiving module perform frequency matching, and signals are received and transmitted at a second frequency after the frequency matching is completed. Judging whether the DTV signal is switched to a channel or not by the DTV receiving module, and continuously judging whether the currently played DTV signal is the DTV signal or not when the channel is not switched to the channel; if the DTV signal switches channels, the currently played channel is continuously identified and the first frequency is obtained, so that the transmitting frequency of the subsequent wireless transmitting module can be staggered from the first frequency, and the same-frequency or near-frequency interference of the wireless transmitting module to the receiving of the DTV signal is avoided.
The wireless transmitting system in the application can automatically identify the current playing channel of the DTV signal, and dynamically adjust the transmitting frequency of the wireless transmitting module according to the first frequency of the current playing channel, so that the second frequency of the wireless transmitting module is different from the first frequency, the wireless transmitting module and the DTV receiving module are ensured to work at different frequencies, the problem of near-frequency or same-frequency interference between the DTV receiving module and the wireless transmitting module is avoided, and the receiving reliability of the DTV signal is effectively improved.
