Embodiment
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 only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
Core of the present invention is to provide a kind of tuner recognition methods of Set Top Box, for identifying the tuner be integrated in Set Top Box.In addition, core of the present invention also provides the tuner recognition device of a kind of Set Top Box corresponding with the method.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment one
Fig. 1 is the flow chart of the tuner recognition methods of a kind of Set Top Box provided by the invention.The tuner recognition methods of Set Top Box comprises the following steps:
S10: the address obtaining each DEMOD in DEMOD catalogue.
S11: the address obtaining each TUNER in TUNER catalogue.
Under normal circumstances, a Set Top Box includes multiple tuner, and the model of each tuner is all different.The model of tuner determines according to DEMOD and TUNER in chip, identifies that the process of high frequency turner models is also the process identifying DEMOD model and TUNER model.In DEMOD catalogue, deposit the address of multiple DEMOD, when certain DEMOD model determined by needs, the address of depositing in DEMOD catalogue need be obtained.Correspond, in TUNER catalogue, deposit the address of multiple TUNER, when certain TUNER model determined by needs, the address of depositing in TUNER catalogue need be obtained.
S12: successively to the address write data of described each DEMOD.
When behind the address getting each DEMOD in DEMOD catalogue, to the address write data got.These data can be arbitrary value, can be single characters, also can be a certain character strings.
S13: judged whether that the first acknowledge character returns.
After the address write data of often couple of DEMOD, all need to have judged whether that the first acknowledge character returns, if do not had, then continue the address write data to next DEMOD.
S14: when there being the first acknowledge character to return, stops write data, and to define the address that the first acknowledge character returns be target DEMOD address.
After the address write data to certain DEMOD, if there is acknowledge character to return, then determine that this address is exactly the address of certain DEMOD, i.e. target DEMOD address.Owing to have found target DEMOD address, therefore no longer need to other addresses write data.
S15: the model determining DEMOD according to described target DEMOD address.
According to the target DEMOD address determined in step S14, search the model of DEMOD corresponding to this address.
S16: write data to the address of described each TUNER successively according to the communication protocol of mating with the model of determined DEMOD;
Because the communication protocol of the correspondence of each DEMOD is different, therefore after determining the model of DEMOD, the communication protocol corresponding according to this model need write data to each TUNER address in TUNER catalogue.These data can be arbitrary value, can be single characters, also can be a certain character strings.
S17: judged whether that the second acknowledge character returns;
After the address write data of often couple of TUNER, all need to have judged whether that the second acknowledge character returns, if do not had, then continue the address write data to next TUNER.
S18: when there being the second acknowledge character to return, stops write data, and to define the address that described second acknowledge character returns be target TUNER address;
After the address write data to certain TUNER, if there is acknowledge character to return, then determine that this address is exactly the address of certain TUNER, i.e. target TUNER address.Owing to have found target TUNER address, therefore no longer need to other addresses write data.
S19: the model determining TUNER according to described target TUNER address;
According to the target TUNER address determined in step S18, search the model of TUNER corresponding to this address.
S20: according to the model of determined DEMOD and the model of described TUNER, determine high frequency turner models.
The model of the TUNER that the model of the DEMOD determined according to step S15 and step S19 determine just can determine corresponding high frequency turner models, so far completes the identification of tuner.In concrete enforcement, just can select corresponding driver according to the model of this tuner.
In order to allow those skilled in the art more understand method provided by the invention, provide tuner identifying here.It should be noted that here just for two kinds of DEMOD and two kind of TUNER, is not comprise all situations.See table 1, table 1 is the high frequency turner models table of comparisons of Set Top Box.
Table 1
In each DEMOD address, write data, when address 0xd2 has the first acknowledge character to return, then determine that 0xd2 is target DEMOD address, determine that DEMOD model is DEMOD2 further.The communication protocol of being mated by DEMOD2, to the address write data of each TUNER, when address 0xc1 has the second acknowledge character to return, is then determined that 0xc1 is target TUNER address, is determined that TUNER model is TUNER1 further.Just determining high frequency turner models by DEMOD2 and TUNER1 is tuner 3.
The method that the present embodiment provides only needs the model by determining DEMOD and TUNER just can determine corresponding high frequency turner models, and determines that the process of DEMOD and TUNER model is just to each register write data, therefore speed.Meanwhile, this method does not need to drive each tuner, just selects corresponding driver to drive, therefore save time after only having identification.In addition, not needing to rely on manufacturer when determining DEMOD and TUNER model provides chip identification method, effectively reduces the problem that recognition methods disunity brings.
It should be noted that, step S12 can, for identical, also can be different, as long as acknowledge character can be had to return with the data write in step S16.
