Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
Embodiment one:
Referring to Fig. 1, Fig. 1 is the signal of the embodiment based on live signal adjustment parameter method of set-top box of the present invention
Figure.
Fig. 1 includes step S11: the parameter of the Signal Regulation set-top box received according to set-top box；Wherein, the parameter packet
Include the roll-off factor of the gain of tuner and/or the set-top box of DVB-S/S2 standard.
In the present embodiment, by adjusting the roll-off factor of the gain of tuner and/or the set-top box of DVB-S/S2 standard,
The mosaic phenomenon or leakage platform phenomenon of the DTV being connected with set-top box can be improved.
Embodiment two:
Fig. 2, Fig. 3 and Fig. 4 are please referred to, Fig. 2 is set-top box of the present invention based on the another of live signal adjustment parameter method
The flow diagram of embodiment；Fig. 3 is the schematic diagram of an embodiment of the S22 step of Fig. 2；Fig. 4 is the one of the S222 step of Fig. 3
The schematic diagram of embodiment.
As shown in Fig. 2, Fig. 2 is comprising steps of S21. reads the adjustment parameter mode of the set-top box；Step S22: according to this
The parameter of live signal and the adjustment parameter mode tuning set-top box.
It optionally, further include step (not shown) before step S21: the movement setting of the input equipment of receiving set up box
Adjustment parameter mode；Wherein, which is the menu button being set on set-top box or touch display screen or and set-top box
The external equipment of communication.
Specifically, as shown in figure 3, the step S22 of Fig. 2 is comprising steps of S221: real-time with this according to the adjustment parameter mode
Signal, setting are included in the optional network specific digit in optional network specific digit section；Step S222: according to the optional network specific digit, the parameter is adjusted.
Specifically, as shown in figure 4, the step S222 of Fig. 3 is comprising steps of S2221: according to the optional network specific digit, modifying the machine
The value of the register of top box；Step S2222: the parameter is arranged by the value of the register.
Further, the adjustment parameter mode of set-top box includes manual mode and automatic mode.Automatic mode includes automatic
Open (Auto/ON) mode and automatic pass (Auto/OFF) mode.In practical work process, when occur mosaic phenomenon or leakage platform
When the failures such as phenomenon, user can enter OSD menu, and set-top box is provided with model selection in OSD menu, by receiving user's choosing
Instruction is selected, associative mode can be entered.
When adjustment parameter mode is automatic die sinking formula, which is randomly provided according to the live signal；
When adjustment parameter mode is automatic pass mode, the optional network specific digit being stored in the memory of the set-top box is read,
The optional network specific digit is set；
When adjustment parameter mode is manual mode, the optional network specific digit is arranged in the movement of the input equipment of receiving set up box.
Wherein, which is stored in the nonvolatile memory of set-top box.
Below to adjust the gain concrete example introduction of tuner.
The register is one group of register of the AGC of coordinator (tuner).The optional network specific digit be included in digital section [6,
7,8,9,10,11,12,13,14,15] in, the relation mapping table of the gain of the optional network specific digit and tuner is as follows:
If reading adjustment parameter mode is (Auto/ON) mode of opening automatically, the processor of set-top box is according to real-time letter
Number it is randomly provided the first optional network specific digit, for example the first optional network specific digit being randomly provided for the first time is 11, then correspondingly changes this and post
The value of storage is 10, and accordingly the gain of the tuner of set-top box is set as 7.5db.Clock every few seconds is randomly provided for the second time
First optional network specific digit is 8 or 14, then the value for correspondingly changing the register is 8 or 14, and accordingly the gain of the tuner becomes
3db or 11d is turned to, is so analogized.
At this point, user can be according to the picture situation of DTV, it is determined whether close automatic die sinking formula, i.e., starting is automatic closes
(Auto/OFF) mode.If being adjusted to optimum, starts automatic pass mode, read the memory for being stored in set-top box
(flash) the second optional network specific digit in, it is second optional network specific digit that the optional network specific digit, which is arranged,.Such as, right in the case of automatic die sinking formula
The optional network specific digit for answering DTV best picture situation is 8, if starting at this time is automatic to close mode, the set-top box read
The second optional network specific digit in memory is 8, and the optional network specific digit is arranged at this time and is fixed as 8, and the value for correspondingly changing the register is 8,
Accordingly the gain fixed setting of the tuner of set-top box is 3db, then can lock the optimum of DTV.
If reading adjustment parameter mode is manual (Manual) mode, the movement of the input equipment of receiving set up box.
For example, optional network specific digit option (such as 6-15) can be provided in the OSD menu of set-top box, as user can be in the OSD menu of set-top box
Middle selection/the optional network specific digit (such as 10) is arranged, then set-top box correspondingly changes the value of the register according to the optional network specific digit option
It is 10, accordingly the gain of the tuner of set-top box is set as 6db.
In the present embodiment, the parameter of the optional network specific digit de-regulation set-top box in optional network specific digit section is included in by being arranged,
User-friendly, user is not necessarily to grasp the specialized technical knowledge of set-top box, by adjusting the optional network specific digit being easily understood
It realizes the picture effect for adjusting DTV, avoids mosaic phenomenon or leakage platform phenomenon.In addition, adjusting tuner by register
Gain, the processing data speed of processor can be accelerated, improve the performance indicator of set-top box, give the better usage experience of user.
In addition, the present embodiment supports the parameter of manual mode and automatic mode de-regulation set-top box, it is more to be supplied to user
Adjusting selection.Using automatic mode, user's operation is easy to use.Using manual mode, then the spy can be voluntarily set one by one
Fixed number word is avoided because random number can not traverse all digital sections under automatic mode, and may need the long period just can recall most
Good picture effect, or best picture effect can not be recalled.
Embodiment three:
The present invention provides a kind of set-top box, which is able to carry out the method such as embodiment one or embodiment two.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
