detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the invention discloses a signal transmission management method and a set-top box. In the embodiment of the present invention, after the set-top box obtains the transmission parameters of each group of signals in the signal set to be processed during the transmission process; A throw analog switch is a switch included in a circuit that transmits signals in the set of signals to be processed; if matched, all signals in the set of signals to be processed are set to be transmitted using the same interface. In the embodiment of the present invention, the set-top box can set all the signals in the signal set to be processed to be transmitted through the same interface, thereby reducing the number of interfaces of the set-top box and reducing the probability of interface connection errors.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a signal transmission management method disclosed in an embodiment of the present invention. As shown in Figure 1, the signal transmission management method may include the following steps:

S101. Acquire the transmission parameters of each group of signals in the signal set to be processed during the transmission process.

In the embodiment of the present invention, the set of signals to be processed includes at least two groups of different signals, wherein each group of signals has different transmission parameters during transmission. Transmission parameters may include, but are not limited to, transmission bandwidth, transmission signal-to-noise ratio, distortion degree, noise coefficient, and the like.

Transmission bandwidth refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in the transmission pipeline. In digital equipment, transmission bandwidth is usually expressed in bps, which is the number of bits that can be transmitted per second. In analog devices, transmission bandwidth is usually expressed in transmission cycles per second or hertz (Hz). In computer network applications, transmission bandwidth refers to the frequency range occupied by various frequency components contained in the signal. Transmission bandwidth also indicates the ability of a communication line to transmit data. That is, the "highest data rate" that can pass from a certain point in the network to another point in a unit of time.

In the embodiment of the present invention, the transmission signal-to-noise ratio is also referred to as the signal-to-noise ratio. Refers to the ratio of signal to noise in an electronic device or electronic system. The signal refers to the electronic signal from the outside of the device that needs to be processed by the device, and the noise refers to the irregular extra signal (or information) that does not exist in the original signal generated after passing through the device, and the signal does not It does not change with the change of the original signal. The measurement unit of the transmission signal-to-noise ratio is dB, and its calculation method is 10lg (PS/PN), where Ps and Pn represent the effective power of the signal and noise respectively, and can also be converted into the ratio relationship of the voltage amplitude: 20Lg (VS/VN ), Vs and Vn represent the "rms" of the signal and noise voltages, respectively. In an audio amplifier, what we hope is that the amplifier should not add any other extra things besides amplifying the signal. Therefore, the signal-to-noise ratio should be as high as possible. In a narrow sense, it refers to the ratio of the output signal power of the amplifier to the noise power output at the same time. It is often expressed in decibels. The higher the signal-to-noise ratio of the device, the more noise it generates. few. Generally speaking, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal, and the higher the sound quality of the sound playback, otherwise the opposite is true. The signal-to-noise ratio should generally not be lower than 70dB, and the signal-to-noise ratio of high-fidelity speakers should reach above 110dB.

In the embodiment of the present invention, there are many kinds of distortions, such as: harmonic distortion, intermodulation distortion, phase distortion and so on. The technical term for the degree of distortion we usually refer to is Total Harmonic Distortion, in English: Total Harmonic Distortion, or THD for short. Generally, on the power amplifier circuit of multimedia speakers, the THD index refers to the total harmonic distortion when fo = 1KHz sine wave input and the power is 1/2 of the rated output power. We can easily achieve this index below 0.5%. However, when the volume is turned up and the power of the power amplifier is close to the rated power, the THD will start to increase sharply. This is mainly due to the limitation of the power supply, which makes the output of the power amplifier clipping, which is what we call clipping distortion. At this time it is the main ingredient in THD.

In the embodiment of the present invention, the noise figure NF=signal-to-noise ratio of the input terminal/signal-to-noise ratio of the output terminal, and the unit is usually “dB”. This coefficient is a parameter that characterizes the degree of deterioration of the noise performance of the amplifier. The larger the better, the larger the value, the greater the noise mixed in the transmission process, reflecting the unsatisfactory characteristics of the device or channel. In the case of a relatively low noise figure of the amplifier, the noise figure of the amplifier is usually expressed by the noise temperature (T). The amplifying circuit not only amplifies the noise at the input, but also has noise in the amplifying circuit itself. Therefore, the signal-to-noise ratio at the output must be smaller than the signal-to-noise ratio at the input. In an amplifier, the less internal and external noise the better. The greater the noise of the amplifier circuit itself, the smaller the signal-to-noise ratio of its output terminal than the signal-to-noise ratio of the input terminal, and the greater the NF. When NF is expressed in decibels, NF(dB)=10lg(Po/ApPi), Po represents the total noise power at the output end, Pi represents the noise power at the input end of the signal source, and Ap represents the power gain. The relationship between noise factor and noise temperature is: T=(NF-1)T0 or NF=T/T0+1 where: T0-absolute temperature (290K).

S102. Detect whether the transmission parameters match the parameters allowed to be transmitted in the SPDT analog switch.

In the embodiment of the present invention, the SPDT analog switch is a switch included in a circuit that transmits signals in the signal set to be processed.

In the embodiment of the present invention, each SPDT analog switch has its own transmission parameters that can be carried. For example, the minimum transmission bandwidth in SPDT analog switch A is 10bps, and the maximum transmission bandwidth is 100bps; the minimum SNR in SPDT analog switch A is 1dB, and the maximum SNR is 10dB, etc.

In the embodiment of the present invention, in different signal transmission circuits, the parameters of the SPDT analog switch in the circuit can be set to be different, or different SPDT analog switches can be selected according to different needs.

In the embodiment of the present invention, after the set-top box obtains the transmission parameters of each group of signals in the signal set to be processed during the transmission process, it can detect whether the transmission parameters match the parameters allowed to be transmitted in the SPDT analog switch.

S103. If they match, set all the signals in the signal set to be processed to use the same interface for transmission.

In the embodiment of the present invention, when it is detected that the transmission parameters match the parameters allowed to be transmitted in the SPDT analog switch, it can be determined that all the signals in the signal set to be processed can be transmitted through the same interface. For example, when the minimum transmission bandwidth in the SPDT analog switch is 10bps, the maximum transmission bandwidth is 100bps, and there are signal A and signal B in the signal set to be processed, wherein, the transmission bandwidth of signal A is 12bps, and the transmission bandwidth of signal B If the bandwidth is 16bps, it means that both signal A and signal B in the signal set to be processed meet the allowable transmission parameters of the SPDT analog switch, then it can be set that signal A and signal B in the signal set to be processed can be transmitted using the same interface.

In the embodiment of the present invention, after it is determined that all the signals in the signal set to be processed are transmitted through the same interface, it may be further detected whether the transmission parameters of each group of signals in the signal set to be processed are similar. For example, whether the transmission bandwidth is about a certain value. For example: (N+n)bps or (N-n)bps, where N is a reference value, n is a fluctuation value, and N and n are natural numbers.

In Figure 1, after the set-top box acquires the transmission parameters of each group of signals in the signal set to be processed during the transmission process; The switch is a switch contained in a circuit that transmits signals in the signal set to be processed; if matched, all signals in the signal set to be processed are set to be transmitted using the same interface. In the embodiment of the present invention, the set-top box can set all the signals in the signal set to be processed to be transmitted through the same interface, thereby reducing the number of interfaces of the set-top box and reducing the probability of interface connection errors.

For example, the transmission bandwidths of the video signal and the coaxial signal are relatively low, and the transmission bandwidths are similar. Therefore, a set of signals to be transmitted can be formed.

S202. Select a signal with the largest transmission bandwidth from the transmission bandwidths of each group of signals, and use the signal with the largest transmission bandwidth as a reference signal, and use the transmission bandwidth of the reference signal as the reference bandwidth.

In the embodiment of the present invention, after obtaining the transmission bandwidth of each group of signals in the signal set to be processed during the transmission process, the signal with the largest transmission bandwidth can be selected, and the signal with the largest transmission bandwidth can be used as the reference signal, and the reference signal The transmission bandwidth is used as the reference bandwidth. For example, the set of signals to be transmitted includes signal A, signal B, and signal C, wherein, the transmission bandwidth of signal A is 12bps, the transmission bandwidth of signal B is 16bps, and the transmission bandwidth of signal C is 10bps, then the transmission bandwidth of signal B If the bandwidth is the largest, the transmission bandwidth of signal B can be used as the reference bandwidth.

S203. Detect whether the transmission bandwidth matches the allowable transmission bandwidth of the single-pole double-throw analog switch.

S204. If they match, set all the signals in the signal set to be processed to use the same interface for transmission.

In Fig. 2, it is described in detail that when the transmission parameter is the transmission bandwidth, the set-top box can select the signal with the largest transmission bandwidth from the transmission bandwidth of each group of signals, and use the signal with the largest transmission bandwidth as the reference signal, and the reference signal The transmission bandwidth is used as the reference bandwidth, and the transmission bandwidth is matched with the allowable transmission bandwidth of the single-pole double-throw analog switch. If it matches, all the signals in the signal set to be processed are set to be transmitted using the same interface, which can reduce the interface of the set-top box number to reduce the probability of interface connection errors.
