Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of Signal transmissions management method and Set Top Box.In embodiments of the present invention, after Set Top Box to obtain in pending signal set the transformation parameter of each group signal in transmitting procedure; Then whether Set Top Box can detect transformation parameter and mate with allowing the parameter transmitted in single pole double throw analog switch, and single pole double throw analog switch is the switch comprised in the circuit of signal in the pending signal set of transmission; If coupling, then all signals arranged in pending signal set all use same interface to transmit.In embodiments of the present invention, Set Top Box all can use same interface to transmit by all signals arranged in pending signal set, thus can the number of ports of reduce engine top box, connects the probability of makeing mistakes to reduce interface.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of Signal transmissions management method disclosed in the embodiment of the present invention.As shown in Figure 1, this Signal transmissions management method can comprise the following steps:
S101, to obtain in pending signal set the transformation parameter of each group signal in transmitting procedure.
In the embodiment of the present invention, pending signal set comprises at least two group unlike signals, and wherein, the transformation parameter of each group signal in transmitting procedure is different.Transformation parameter can include but not limited to transmission bandwidth, transmission signal to noise ratio, the distortion factor and noise sonic system number etc.
Transmission bandwidth refers to the data quantity can transmitted at a fixed time, that is can transmit the ability of data in transmission pipeline.In digital device, transmission bandwidth represents with bps usually, i.e. the figure place transmitted per second.In analog machine, transmission bandwidth represents with transmission cycle per second or hertz (Hz) usually.In the applications of computer network, transmission bandwidth refers to the frequency range occupied by various different frequency compositions that this signal comprises.Transmission bandwidth also represents that communication line can transmit the ability of data.Namely within the unit interval from certain network a bit to another point by " the maximum data rate ".
In the embodiment of the present invention, transmission signal to noise ratio is also called signal to noise ratio.Refer to the ratio of signal and noise in an electronic equipment or electronic system.This signal refers to be needed to carry out by this equipment the electronic signal that processes from device external, noise to refer in the original signal produced after this equipment and non-existent random extra (or information), and this kind of signal does not change with the change of original signal.The unit of measurement of transmission signal to noise ratio is dB, its computational methods are 10lg (PS/PN), the wherein effective power of Ps and Pn difference representation signal and noise, also the ratio of voltage magnitude can be converted into: " effective value " of 20Lg (VS/VN), Vs and Vn difference representation signal and noise voltage.In audio frequency amplifier, we desirably this amplifier except amplifying signal, should not add other extra thing any.Therefore, signal to noise ratio should be more high better, and narrow sense refers to the power of the output signal of amplifier and the ratio of the noise power simultaneously exported, and usually represents with decibels, and the higher noise showing that it produces of the signal to noise ratio of equipment is fewer.In general, signal to noise ratio is larger, and illustrate that the noise be mixed in signal is less, the sound quality of acoustic playback is higher, otherwise on the contrary.Signal to noise ratio generally should lower than 70dB, and the signal to noise ratio of Hi-Fi sound-box should reach more than 110dB.
In the embodiment of the present invention, because distortion has multiple, as: harmonic distortion, intermodulation distortion, phase distortion etc.The technical term of our the usual said distortion factor is total harmonic distortion, and English is: TotalHarmonicDistortion, is called for short THD.General on the power amplifier of multimedia loudspeaker box, the index of THD refers in the input of fo=1KHz sine wave, the total harmonic distortion of power when 1/2 rated output power, this index we can accomplish less than 0.5% easily.But, when volume is opened greatly, when the power of power amplifier reaches close to rated power, THD can start sharply to increase, and this makes power amplifier occur clipping phenomena mainly due to the restriction of power, namely our said clipping distortion, this time, it was the main composition in THD.
In the embodiment of the present invention, noise factor NF=input signal to noise ratio/output signal to noise ratio, unit commonly uses " dB ".This coefficient characterizes the parameter of noiseproof feature deterioration degree of amplifier, and be not be the bigger the better, its value is larger, illustrates that the noise mixed in transmitting procedure is also larger, reflects the undesirable of device or the characteristic of channel.When the noise factor of amplifier is lower, the noise factor of usual amplifier represents by noise temperature (T).Amplifying circuit not only amplifies the noise of input, and amplifying circuit itself also exists noise.So the signal to noise ratio of its output must be less than input signal to noise ratio.In the amplifier, internal noise and external noise are better less.The noise of amplifying circuit own is larger, and its output signal to noise ratio is more less than input signal to noise ratio, and NF is larger.When NF represents with decibel, NF (dB)=10lg (Po/ApPi), Po represents the total noise power of output, and Pi represents signal source input noise power, and Ap represents power gain.The pass of noise factor and noise temperature is: T=(NF-1) T0 or NF=T/T0+1 wherein: T0-absolute temperature (290K).
