Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
The embodiment of the invention discloses a kind of signal transfer management method and set top box.In embodiments of the present invention, in machine
Top box is obtained in pending signal set after configured transmission of each group of signal in transmitting procedure；Then set top box can be detected
Configured transmission allows whether the parameter of transmission matches in being switched with single pole double throw analog, single pole double throw analog switch is waited to locate to transmit
The switch included in the circuit of signal in reason signal set；If matching, sets all signals in pending signal set
All transmitted using same interface.In embodiments of the present invention, set top box can be all in pending signal set by setting
Signal is all transmitted using same interface, so as to reduce the number of ports of set top box, to reduce the probability of interface connection error.
Referring to Fig. 1, Fig. 1 is a kind of schematic flow sheet of signal transfer management method disclosed in the embodiment of the present invention.Such as
Shown in Fig. 1, the signal transfer management method may comprise steps of：
Configured transmission of each group of signal in transmitting procedure in S101, the pending signal set of acquisition.
In the embodiment of the present invention, pending signal set includes at least two groups unlike signals, wherein, each group of signal exists
Configured transmission in transmitting procedure is different.Configured transmission can include but is not limited to transmission bandwidth, transmission signal to noise ratio, the distortion factor with
And noise sonic system number etc..
Transmission bandwidth refers to the data quantity that can be transmitted at a fixed time, that is, can transmit in transmission pipeline data
Ability.In digital device, transmission bandwidth is generally represented with bps, i.e., the digit per second transmitted.In analog machine, pass
Defeated bandwidth is generally represented with transmission cycle per second or hertz (Hz).In the applications of computer network, transmission bandwidth refers to the letter
Frequency range occupied by number various different frequency compositions included.Transmission bandwidth also illustrates that communication line can transmit data
Ability.From the certain point in network to another " the maximum data rate " put and can passed through i.e. within the unit interval.
In the embodiment of the present invention, transmission signal to noise ratio is also known as signal to noise ratio.Refer in an electronic equipment or electronic system
The ratio of signal and noise.The signal refers to needing the electronic signal that is handled by this equipment from device external,
Noise refers to by the original signal produced after the equipment and non-existent random extra (or information), and this kind
Signal does not change with the change of original signal.The measurement unit for transmitting signal to noise ratio is dB, and its computational methods is 10lg (PS/
PN), the effective power of wherein Ps and Pn difference representation signals and noise, can also be converted into the ratio of voltage magnitude：
20Lg (VS/VN), Vs and Vn distinguish " virtual value " of representation signal and noise voltage.In audio-frequency amplifier, it is intended that
Be the amplifier in addition to amplified signal, any other extra thing should not be added.Therefore, signal to noise ratio should get over Gao Yue
It is good, the power and the ratio of the noise power of output simultaneously of the output signal of amplifier are referred to for narrow sense, decibels table is usually used
Show, the signal to noise ratio of equipment is higher, and the noise for showing that it is produced is fewer.In general, signal to noise ratio is bigger, illustrates to be mixed in signal
Noise is smaller, and the sound quality of acoustic playback is higher, otherwise conversely.Signal to noise ratio typically should not be below 70dB, Hi-Fi sound-box
Signal to noise ratio should reach more than 110dB.
In the embodiment of the present invention, because distortion has a variety of, such as：Harmonic distortion, intermodulation distortion, phase distortion etc..We
Usually the technical term of the described distortion factor is total harmonic distortion, and English is：Total Harmonic Distortion, referred to as
THD.Typically on the power amplifier of multimedia loudspeaker box, THD index refers to input in fo=1KHz sine waves, and power is 1/2
Total harmonic distortion during rated output power, this index we can easily accomplish less than 0.5%.But, work as volume
Open big, when the power of power amplifier is reached close to rated power, THD can start to sharply increase, this mainly due to power limitation,
Power amplifier is occurred in that clipping phenomena, that is, the clipping distortion described in us, this when it be in THD it is main into
Point.
In the embodiment of the present invention, noise coefficient NF=inputs signal to noise ratio/output end signal to noise ratio, unit commonly uses " dB ".Should
Coefficient characterizes a parameter of the noiseproof feature deterioration degree of amplifier, is not to be the bigger the better, its value is bigger, illustrates passing
The noise mixed during defeated is also bigger, reflects the undesirable of device or the characteristic of channel.In the noise coefficient of amplifier
In the case of relatively low, the noise coefficient of usual amplifier is represented with noise temperature (T).Amplifying circuit is not only input
Noise amplifies, and there is also noise in itself for amplifying circuit.So, the signal to noise ratio of its output end must be less than input signal to noise ratio.
In the amplifier, internal noise and external noise are smaller better.Amplifying circuit noise itself is bigger, and its output end signal to noise ratio is got over
Less than input signal to noise ratio, NF is bigger.When NF is represented with decibel, NF (dB)=10lg (Po/ApPi), Po represents output end
Total noise power, Pi represents signal source input noise power, and Ap represents power gain.The pass of noise coefficient and noise temperature
It is to be：T=(NF-1) T0 or NF=T/T0+1 are wherein：T0- absolute temperature (290K).
S102, detection configured transmission allow whether the parameter of transmission matches in being switched with single pole double throw analog.

Middle lowest signal-to-noise is 1dB, and maximum signal to noise ratio is 10dB etc..
In the embodiment of the present invention, in different signal circuits, single pole double throw analog in circuit can be switched
Parameter is set to difference, or, need to switch from different single pole double throw analogs according to different.
In the embodiment of the present invention, the set top box biography of each group of signal in transmitting procedure in pending signal set is obtained
After defeated parameter, then it can detect that configured transmission allows whether the parameter of transmission matches in being switched with single pole double throw analog.
If S103, matching, set all signals in pending signal set all to be transmitted using same interface.
In the embodiment of the present invention, the parameter of transmission is allowed to match in detection configured transmission is switched with single pole double throw analog
When, then it can determine that all signals in pending signal set can use same interface to transmit.For example, hilted broadsword is worked as
Minimum transmission bandwidth is 10bps in double-throw analog switch, and maximum transmission bandwidth is 100bps, and has letter in pending signal set
Number A and signal B, wherein, signal A transmission bandwidth is 12bps, and signal B transmission bandwidth is 16bps, then illustrates pending letter
What signal A and signal B were satisfied by single pole double throw analog switch in number set allows the parameter of transmission, then can set pending letter
Number set in signal A and signal B same interface can be used to transmit.
In the embodiment of the present invention, it is determined that all signals in pending signal set all transmit it using same interface
