Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
The present invention has mainly used I
2C (Inter-Integrated Circuit) bussing technique copies to television channel information on the cloning device, the channel information on the cloning device is copied on the more television set again, thereby has realized the cloning function of television channel.
I
2The C bus is a kind of bus that is used to connect primary processor and ancillary equipment thereof, I
2The topmost advantage of C bus is that it is simple and efficient.Because interface is set directly on the assembly, so that it takes up room is little, reduced the space of circuit board and the quantity of chip pin, have application fields.I
2The C universal serial bus has two holding wires: a two-way data wire SDA; Another root is clock line SCL.All receive I
2The serial data of the equipment on the C bus is all received the sda line of bus, and the clock line SCL of each equipment receives the scl line of bus.The operation of bus be the transmission of data by host computer control, so-called main frame be log-on data transmission, send clock signal, transmit the equipment that sends stop signal when finishing, main frame is a microprocessor usually, the equipment of being looked for by main frame all is called slave.In order to carry out communication, each receives I
2The equipment of C bus all has a unique address, so that main frame is looked for.The data of main frame and slave transmit, and can send data to slave by main frame, also can be dealt into main frame by slave.
As shown in Figure 1, the principle and the whole implementation that realize of television channel cloning function as can be seen: send order to the MCU of television set inside by user interface, the order that sends mainly contains two: one is that the television channel information among the inner EEPROM of television set is copied on the cloning device, and another is that the television channel information on the cloning device is transplanted in the inner EEPROM of television set.And data all are through I
2The C bus is transmitted.After operation ran succeeded, MCU sent prompting to the user.
Fig. 2 shows the hardware elementary diagram of outside cloning device, and described cloning device is made up of external shell (not shown), interface CN1 and memory N1, and interface CN1 is arranged on the housing, links to each other with the television set interface, realizes the transmission of bus data.Described interface CN1 includes 4 ports, 1 end connect the television set input+the 5V DC power supply, 2 end ground connection, 3 ends and 4 ends are respectively through bus data end 6 pin and bus clock end 5 pin of resistance R 1, R2 connected storage N1.Described memory N1 is arranged on the enclosure interior of cloning device, adopting a model is that the eeprom memory of AT24C08 is realized, its 3 pin is connected with 8 pin import+the 5V DC power supply, N1 provides working power for memory, and respectively through filter capacitor C1, C2 ground connection, 1,2,4,7 pin ground connection.Transfer of data flow process between described cloning device and the television set is referring to Fig. 3, shown in Figure 4.
From data flow always, the television channel cloning function is the process of the mutual duplicate copy of inner EEPROM information and outside EEPROM information.As can be seen from Figure 3: read channel information or write channel information all through an I
2C read operation and an I
2The C write operation, just data flow is opposite.Channel information comprises general information and channel hop information, and general information comprises channel information such as channel, frequency, S-SYSTEM, sound standard.The data buffer zone of suitable size is set among the RAM of MCU in television set, will be at every turn from I
2The channel information that reads in the C buffering area is stored in the data buffer zone of MCU, again the channel information in the data buffer zone is passed through I
2The C bus writes among the target EEPROM.Because channel general information and channel hop information is in same continuous address, therefore, I
2C bus read-write operation must be through twice addressing (subaddressing).Its specific implementation step is referring to Fig. 4.
Fig. 4 is example to duplicate channel information to the process of cloning device, describes the specific implementation step of reproducer in detail.
1, clones the quantity of channel as required, the size of MCU data buffer zone is set; Need the quantity of clone's channel can directly influence time and the efficient that program is carried out, because I
2The size of C bus buffer district and data buffer zone all is conditional, clones the size of the information capacity of channel greater than buffering area if desired, then can increase I
2The read-write number of times of C;
2, client layer sends television channel clone sense order, calls inner_to_outer () function, starts channel and reads function;
3, I is set
2C reads the subaddressing that the address is the inner EEPROM channel hop of a television set information, calls I
2C reads Function e 2p_read (), carries out I with interrupt mode
2The C read operation is read I with channel hop information
2C buffering area g_i2c_buff[] in;
4, with channel hop information from I
2C buffering area g_i2c_buff[] copy to the channel hop data buffer zone g_pos_skip[of MCU] in;
5, the subaddressing that the I2C write address is outside cloning device EEPROM channel hop information is set, calls I
2C writes function skip_e2p_write_external (), and the channel hop data buffer zone from MCU writes cloning device with channel hop information;
6, I is set
2C reads the subaddressing that the address is inner EEPROM channel general information, calls I
2C reads Function e 2p_read (), carries out I with interrupt mode
2The C read operation is read I with the channel general information
2C buffering area g_i2c_buff[] in;
7, with the channel general information from I
2C buffering area g_i2c_buff[] copy to the channel general information data buffer zone g_pos_data[of MCU] in;
8, I is set
2The C write address is the subaddressing of outside cloning device EEPROM channel general information, calls I
2C writes function skip_e2p_write_external (), and the channel general information data buffer zone from MCU writes cloning device with the channel general information;
9, because the size of buffering area is conditional, and the channel general information comprises 3 bytes, once duplicate the restriction (if buffer size is restricted to 255) that 100 channels will exceed the data buffer zone, at this moment, can several times the channel general information be written in the cloning device in 6,7,8 minutes by repeating step.
The process of channel information being transplanted to the inner EEPROM of television set from outside cloning device EEPROM only is I with above-mentioned to duplicate channel information identical to the process of cloning device
2The C transfer of data flows to opposite, here repeats no more.
Native system has designed two kinds of user interface mode, and to adapt to different demands: a kind of is user EXEC, towards general TV user, utilizes user remote controller, by the actions menu of television set, realizes the channel cloning function; Another kind is a factory mode, operates under mode bus, finishes the channel cloning function, is applicable to factory's debugging use.
The present invention is by being written to said procedure software among the MCU of television set, the user only needs just can carry out duplicating and transplanting of television channel by remote controller and a cloning device, has made things convenient for operating personnel that the unification of multiple TV set is provided with work.Certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
