Channel list update method and terminal equipment

Abstract

The embodiment of the invention relates to the technical field of digital televisions, and especially relates to a channel list update method and terminal equipment used for improving the update rate of a channel list stored by a UI (User Interface) module after the terminal equipment receives a channel edit instruction. The method comprises the following steps: receiving a channel editing instruction by the terminal equipment; executing an operation corresponding to channel update information on a channel list identified by a channel list identifier stored in an underlying data module by the terminal equipment according to the channel editing instruction, and executing an operation corresponding to the channel update information on a channel list identified by a channel list identifier in a user interface module channel buffer pool according to the channel editing instruction. According to the channel list update method provided by the invention, since the operation corresponding to the channel update information is executed on the UI module directly according to the channel editing instruction, the update rate of the channel list in the UI module channel buffer pool can be improved after the terminal equipment receives the channel editing instruction.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of digital television, in particular to a method for updating a channel list and a terminal device. Background technique [0002] In the process of using a terminal device such as a TV, a user often uses the function of editing a channel list. Generally, multiple channel lists are stored in the underlying database in the TV, and each channel list mainly includes information such as a channel sequence number, a channel identifier, and a main frequency of a channel. Every time the TV is turned on, the user interface UI module will obtain the channel list from the underlying database and store it in the user interface (User Interface, UI for short) module. When the user selects a channel while using the TV, the channel list stored in the UI module is opened, and the channel list is displayed on the user interface in time. [0003] In the prior art, if the user wants to edit the chann...

Although this process can ensure that the channel list in the UI module and the underlying database are synchronized, an iterator needs to be created after each channel edit to read the channel list in the underlying database. The process of reading the channel list in the underlying database takes a long time, resulting in the channel list stored in the UI module The update rate is affected, especially when the number of channels is relatively large
