In one embodiment of the invention, the predetermined time interval is 15 seconds.
In one embodiment of the present invention, step 32 may comprise:
in step 321, the IPTV module 1 initiates a check request to the routing module 2 at a predetermined time interval.
In step 322, in response to receiving the check request sent by the IPTV module 1, the routing module 2 sends the second check code to the IPTV module 1.
In step 323, the IPTV module 1 determines whether the second check code is consistent with the first check code.
In step 33, if the second check code is inconsistent with the first check code, the IPTV module 1 requests the routing module 2 to synchronously update the inconsistent routing module information to the IPTV module 1.

Based on the set-top box routing module information synchronization method provided by the embodiment of the invention, routing module information such as routing parameters, network states, equipment connection information and the like is quickly synchronized between the IPTV module and the routing module through a newly added IPTV module and routing module synchronization mechanism, so that state change perception and quick synchronization of the routing module can be realized, and the problems of fault location and information asynchronization are solved.

Fig. 4 is a schematic diagram of a set-top box routing module information synchronization method according to a second embodiment of the present invention. Preferably, the embodiment can be executed by the set-top box of the invention. As shown in fig. 4, the method may include:
and step 41, synchronizing the routing module information when the mobile terminal is started for the first time.
When the mobile terminal is started for the first time, the IPTV module 1 and the routing module 2 both store default routing information from the factory. The IPTV module 1 and the routing module 2 respectively generate a first check code (IPTV module check code) and a second check code (routing module check code) according to the respective stored routing module information.
The IPTV module 1 and the routing module 2 each generate and store a string of check codes with all 0 bytes in a memory. The routing module information includes routing parameters such as network state information, routing state information, device connection information, and the like. Each byte represents a routing parameter. For example, in fig. 2, the first byte "00000000" represents the status of the broadband account/password.
And step 42, daily starting up to carry out information synchronization of the routing module.
When the IPTV module 1 is started up in daily time, a check request is initiated to the routing module 2, and if no response exists in the appointed time, the IPTV module 1 prompts that the routing state is abnormal.
And 43, synchronizing the routing module information during daily operation.
In one embodiment of the present invention, the step 43 may include:
in step 431, the IPTV module 1 initiates a verification request to the routing module 2 at a predetermined time interval (e.g. every 15s), and the routing module 2 sends the verification second verification code to the IPTV module 1.
Step 432, the IPTV module 1 determines whether the second check code is consistent with the first check code.
In one embodiment of the present invention, step 432 may comprise:
step 4321, the IPTV module 1 performs xor on the routing module check code and the check code stored in the IPTV module, and determines whether the routing module check code is consistent with the locally stored check code according to the result obtained by the xor.
Step 4322, if the xor result is all 0 s, it is determined that the second check code is identical to the first check code, and no information synchronization of the routing module is required.
In step 4323, if the xor result has a non-0 byte, counting the number of bits with "1" in the non-0 byte.
Step 4324, if the number of bits with "1" is not greater than 4, setting the non-0 byte to all 0, and determining that the second check code is identical to the first check code without performing information synchronization of the routing module.
4325, if the number of bits with "1" is greater than 4, setting the non-0 byte to all 1, and determining that the second check code is inconsistent with the first check code; step 433 is then performed.
In step 433, if the second check code is inconsistent with the first check code, the IPTV module 1 analyzes the second check code, and determines the routing module information (i.e., the changed routing module information) of which the IPTV module 1 is inconsistent with the routing module 2.
In step 434, the IPTV module 1 sends a synchronization request to the routing module 2, where the synchronization request includes codes of inconsistent routing module information.
In step 435, the routing module 2 synchronously updates the inconsistent routing module information (i.e., the routing module information with the change) to the IPTV module 1.
As shown in fig. 2, in the embodiment, according to the xor result of the second check code and the first check code, the broadband account/password in the routing parameter and the PPPoE status bit in the network status information are known, and the check results of the two parameters are all 1, then the routing module 2 synchronously updates the information of the broadband account/password and the PPPoE status bit to the IPTV module 1.
And step 44, synchronizing the routing module information when the routing state is changed.
When a user changes a routing state through an IPTV module setting interface, the IPTV module 1 initiates a routing state change application to the routing module 2, and modifies a routing state storage area in the routing module:
(1) the IPTV module 1 uploads the first check code to the routing module;
(2) the routing module performs exclusive or operation on the first check code (IPTV module check code) and a second check code stored locally:
if the bytes of the xor result check code are all '00000000', the routing state information synchronization is not required.
If the XOR result has a non-0 byte, counting the number of bits of the byte which are 1: if the number of the bit positions of 1 is not more than 4, setting the byte to be all 0 without carrying out route state information synchronization; if the number of the bits of "1" is greater than 4, the IPTV module 2 initiates a synchronization request to the routing module 1, and updates the corresponding information parameters synchronously.
And step 45, updating the check code.
After the information synchronization is completed, the IPTV module 1 and the routing module 2 update the first check code and the second check code, respectively.
For example: after the information synchronization is completed, the check codes of the IPTV module 1 and the routing module 2 may be reset to "00000000".
In one embodiment of the present invention, step 44 may comprise:
