Method for managing interface link for set-top box user

[0013] The user interface link management method of the set-top box of the present invention is to switch the user operation interface independently, and assign a state ID to each user software operation interface, and use the state ID to point to some fixed static state or run some specific Operation function, switching between operation interfaces is actually transformed into switching between state IDs.

[0014] See figure 1 As shown, it specifically includes the following 3 steps:

[0015] 1. Initialization steps: initialize the menu state depth, automatically locate a certain default state ID, and enter the corresponding function interface function of the ID;

[0016] 2. State change step: If the user enters a specific execution instruction, or the timer sends a request, or other processes start related operations, and exit from the functional interface after changing the next execution state ID, the program will respond and Set the next execution state to a related ID. When the instruction is executed, the current state ID will be updated to the next state ID, and the state depth will be incremented by one, and the entire operation path will be recorded at the same time; if the instruction is a shortcut operation Instruction, the program will change the next state ID value to the default state ID specified by the user operation, and default the state depth to the initial value;

[0017] 3. Status comparison step: Compare the current status ID with the next status ID. If the operation is consistent, it means that the operation is not a shortcut operation. The program will return to the previous status ID according to the default path selection and enter the specific function indicated by the relevant ID; If they are inconsistent, the operation is a shortcut operation. The program will select a specific function and run according to the next state ID set by the previous operation.

[0018] Another example figure 2 As shown, there are a total of n operation interfaces in the figure, and each operation interface is equipped with a state ID.

[0019] During operation, assume that the initial default interface is "Operation Interface 1", the link length is 1, and ID1 is recorded to the linked list.

[0020] When the user enters a specific execution instruction, it is necessary to switch from "Operation Interface 1" to "Operation Interface 2", the program will respond and set the next execution state "Operation Interface 2" to a certain related ID2, which will also be executed while executing the instruction. The current state "operation interface 1" ID1 will be updated to the next state ID2, and the link depth will be increased by 1, and ID2 will be recorded in the link table.

[0021] When the user performs a return operation in "Operation Interface 2", the link depth is reduced by 1, the "Operation Interface 1" ID1 of the upper-level interface is read from the link table, and the corresponding operation of "Operation Interface 1" is performed;

[0022] When the timer triggers the timing operation and requires the execution of the "timing operation interface", the link depth is defaulted to 1, and the next state ID is set to ID4, and the "timing operation interface" is executed from the current interface.
