Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The digital television provided by the embodiment of the invention is a digital television all-in-one machine, and comprises a PCMCIA interface, wherein a condition receiving module CICAM is inserted into the PCMCIA interface, and after the digital television is started, programs can be normally played after the initialization process of hardware and the communication of application data between software of a digital television system and the CICAM are carried out. In the prior art, the time for inserting the CICAM into the PCMCIA interface of the digital television to complete the initialization process of the interface is at least 6 seconds, and the time for completing the communication of the application data to play the scrambled program is 12 seconds, that is, 18 seconds are needed to play the program at the fastest after the start-up, and the user needs to wait for a long time to watch the television program after executing the start-up action, so that the watching experience needs to be improved.
In view of this, an embodiment of the present invention provides an initialization method for a digital television interface, where a conditional access module is inserted into the digital television interface; fig. 1 shows a schematic flowchart of an initialization method for a digital television interface according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes:
s101: when starting up, obtaining the card information structure of the stored condition receiving module;
s102: configuring a register according to a card information structure;
s103: switching the digital television interface into an input/output mode, executing an initialization process of the digital television interface, and executing S104 when the initialization is successful; when the initialization is abnormal, executing S105;
s104: finishing the initialization process;
s105: and reading the card information structure of the conditional access module inserted into the current digital television interface, updating the currently stored card information structure by using the read card information structure, and turning to S102.
The Card Information Structure (CIS) is configuration information for register configuration of the digital television universal interface, and is acquired when the PCMCIA is initialized, and the offset (COR offset) of the register and the configuration table index byte (TPCE _ INDX) are configured. In practical application, the configuration process of the register is performed in a storage Mode (memorylmode), and after the configuration of the register is completed, the register is switched to an input/output Mode (I/O Mode) to perform configuration of other parameters, thereby completing initialization of the digital television interface. However, the slow speed of reading the card information structure CIS of the conditional access module CICAM in the storage mode affects the fact that the whole boot process takes a long time to play the program. Therefore, in the embodiment of the present invention, the card information structure of the conditional access module is stored in advance, and the boot program is changed accordingly, so that the digital television directly acquires the stored card information structure after being turned on to configure the register, and even if the process is still performed under the memorylmode, the process can be completed only within several milliseconds. In practical application, after the user inserts the CICAM into the PCMCIA interface of the digital television, the CICAM is generally not changed, so that the starting speed is greatly increased under the condition except the condition of starting for the first time, and the configuration of the playing program can be finished within 12 seconds at the fastest speed.
In the specific implementation process, the action of storing the CIS of the CICAM can be manually stored in a flash memory (flash), and can also be read and stored in the flash memory and a system memory when the CICAM is started for the first time after the CICAM is inserted into the digital television. Then, in the case of the first startup after the CICAM is inserted into the digital television, it may fail to acquire the stored card information structure of the conditional access module, and therefore, in the above-mentioned embodiment of the present invention, in S101, when the acquisition of the stored card information structure of the conditional access module fails, the card information structure of the conditional access module inserted into the current digital television interface is read, and the read card information structure is stored.
For example, when a user inserts the CICAM into a PCMCIA interface of the digital television and starts the digital television for the first time, and the acquisition of the stored CIS information fails, that is, when the CIS is not stored in the flash memory, the CIS is directly read from the CICAM and stored in the flash memory and the memory, and the initialization is performed according to the read CIS. In the second and later starting process of each time, the system automatically acquires the stored CIS and performs initialization configuration according to the acquired CIS, so that the speed of initializing a subsequent interface is increased.
In another possible case, when the stored card information structure is obtained, and the obtaining operation fails due to a process error, the card information structure of the conditional access module inserted into the current digital television interface may be read, and the read card information structure may be used to update the currently stored card information structure.
In the case of replacing the CICAM halfway during the use of the user, the system acquires the stored CIS to perform initialization configuration, but the CIS does not match the currently inserted CIS of the CICAM, which may cause an initialization abnormality. Then the system will start the process at this moment, read the card information structure of the condition receiving module inserted in the current digital television interface again, and carry on the initialization configuration according to the card information structure, can still start the system normally finally. And when reading a new CIS, updating the currently stored CIS by using the newly read CIS, and when starting up next time, acquiring the updated CIS. The situation that the CICAM is replaced by the user in the midway does not occur frequently in practical application, so that the method provided by the embodiment of the invention can effectively improve the initialization speed of hardware, thereby improving the user experience.
In order to solve the same technical problem, an embodiment of the present invention further provides another method for initializing a digital television interface, where a conditional access module is inserted into the digital television interface, and as shown in fig. 2, the method specifically includes:
s201: when starting up, obtaining the card information structure of the stored condition receiving module;
s202: configuring a register according to a card information structure;
s203: switching the digital television interface into an input/output mode, and reading a card information structure of a conditional access module inserted into the current digital television interface;
s204: verifying whether the read card information structure is consistent with the currently stored card information structure, and executing S205 when the read card information structure is consistent with the currently stored card information structure; when the inconsistency is verified, S206 is executed;
s205: executing an initialization process of the digital television interface;
s206: the currently stored card information structure is updated with the read card information structure, and the process goes to S202.
In the embodiment of the invention, the card information structure of the conditional access module is pre-stored, and when the device is started, the stored card information structure is directly acquired to configure the register without reading the card information structure in the conditional access module, thereby accelerating the initialization speed of the PCMCIA interface. After the digital television interface is switched to the input/output Mode (I/O Mode), the card information structure of the conditional access module inserted into the current digital television interface is read, and the card information structure is used to verify whether the stored card information structure is correct, that is, whether the read card information structure is consistent with the currently stored card information structure. The speed of reading the card information structure at I/O Mode is much faster than that at Memory Mode. Therefore, the initialization process of the digital television interface can be completed quickly when the verification is successful, so that the time consumed in the whole process from starting to playing the program is shortened, and the watching experience of a user is improved.
If the user replaces the CICAM in the middle of the use process, the stored CIS is the CIS of the CICAM used before, so that the verification fails, and the read CIS can be directly used for reconfiguring the register and carrying out subsequent initialization processes. Meanwhile, the previously stored CIS needs to be updated by the read CIS, so that the updated CIS can be directly acquired for an initialization process when the computer is started next time, and the initialization speed is increased. Specifically, the CIS stored in the flash memory and the current system memory may be cleared, and the read CIS may be stored in the flash memory and the memory for use.
Similarly, the CIS of the CICAM may be manually stored in the flash memory, or may be read and stored in the flash memory and the system memory when the CICAM is first powered on after the digital television is inserted into the CICAM. Then, in the case of the first startup after the CICAM is inserted into the digital television, it may fail to acquire the stored card information structure of the conditional access module, and therefore, in the above-mentioned embodiment of the present invention, in S101, when the acquisition of the stored card information structure of the conditional access module fails, the card information structure of the conditional access module inserted into the current digital television interface is read, and the read card information structure is stored. In addition, if the process of acquiring the stored card information structure is wrong, so that the acquisition action is failed, the card information structure of the conditional access module inserted into the current digital television interface can be read, and the read card information structure is used for updating the currently stored card information structure.
In practical applications, a storage flag bit may be set, and whether the CIS is present in the flash memory may be identified by setting the storage flag bit value. Specifically, in the above step S201, when the card information structure of the stored conditional access module is successfully acquired, the storage flag bit may be set to a valid value; the process continues to step S202. Further, in step S203, when it is determined that the storage flag bit is an effective value, the card information structure of the conditional access module inserted into the current digital television interface is read; and if the storage flag bit is determined not to be the valid value, the obtained CIS is not the previously stored CIS, and the obtained CIS is the CIS read in the CICAM inserted into the current digital television interface.
For example, an embodiment of the present invention provides an initialization method for a digital television interface, where a storage flag bit value of 1 is a valid value. As shown in fig. 3, the method may specifically include:
s301: when starting up, obtaining the card information structure of the stored condition receiving module; when the acquisition is successful, executing S302; when the acquisition fails, S310 is executed;
s302: setting a storage flag bit value to 1;
s303: configuring a register according to a card information structure;
s304: switching the digital television interface into an input/output mode, and executing an initialization process of the digital television interface;
s305: determining whether a storage flag bit value is 1; when the storage flag value is 1, executing S306; when the storage flag value is 0, S308 is executed;
s306: reading a card information structure of a conditional access module inserted into a current digital television interface;
s307: verifying whether the read card information structure is consistent with the currently stored card information structure; when the consistency is verified, executing S308; when the inconsistency is verified, S309 is executed;
s308: finishing;
s309: updating the currently stored card information structure with the read card information structure, and executing S301;
s310: reading the card information structure of the conditional access module inserted by the current digital television interface, updating the currently stored card information structure with the read card information structure, and setting the storage flag value to 0, and executing S303.
Based on the same inventive concept, an embodiment of the present invention further provides an initialization apparatus for a digital television interface, as shown in fig. 4, the apparatus includes:

In the initialization process of the digital television interface, the card information structure of the condition receiving module is not required to be read every time, but the stored card information structure is directly adopted for relevant configuration, so that the initialization speed of hardware is greatly improved, the time from starting to playing programs is shortened, and better watching experience is provided for users.
Optionally, the first obtaining module 41 is further configured to, when obtaining the stored card information structure of the conditional access module fails, read the card information structure of the conditional access module inserted by the current digital television interface, store the read card information structure, or update the currently stored card information structure with the read card information structure.

Because the speed of reading the card information structure of the condition receiving module in the input and output mode is much higher, compared with the prior art that the card information structure of the condition receiving module is read in the storage mode for relevant configuration, the method provided by the invention has higher initialization efficiency, accelerates the process from starting to playing programs and improves the user experience.
