Problems solved by technology

[0005] This application provides a method for updating resource data and a set-top box device to solve the problem that resource data stored in other memory spaces cannot be accessed when the set-top box device uses the above-mentioned prior art method to update the received resource data. When the resource data is updated quickly, there will be problems such as operation freeze and resource loss

Embodiment Construction

[0051] As mentioned in the background technology, currently, when the set-top box device updates the received resource data, it releases each memory space of the received resource data one by one, and reallocates the memory space for storing the newly received resource data . For example, if figure 1 As shown, when the set-top box device receives EPG data, according to the pre-established linked list information in the database, a memory space will be allocated to each business, and this memory space will continue to allocate several memory spaces to store different event data for each day; Such as figure 2As shown, when the set-top box device receives the update data of a certain event data, it will use the linked list information to find the existing memory space of the event data and release it, and re-allocate the memory space to store the update data of the event data . However, when resource data is updated in this way, resource data stored in other memory spaces can...

Abstract

The application discloses a resource data update method and set top box equipment, and relates to the technical field of the data update. The method comprises the following steps: querying the first linked list information to which the resource data belongs when the set top box (STB) equipment receives an update notification message of the resource data; creating the second linked list informationsame as the first linked list information format; distributing a new memory space according to the second linked list information, thereby receiving the updated data of the resource data through thenew memory space; replacing the starting address corresponding to the first linked list information in a database with the starting address corresponding to the second linked list information. By using the scheme disclosed by the application, the fast seamless switching can be realized in resource data update, the user is almost free from any influence on the visual perception.

Description

technical field [0001] The present application relates to the technical field of data update, in particular to a method for updating resource data and a set-top box device. Background technique [0002] A Digital Video Converter Box (Set Top Box, STB), commonly referred to as a set-top box or set-top box, is a device that connects a TV set to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is not only the image and sound provided by analog TV, but also digital content, including electronic program guide (Electronic Program Guide, EPG), Internet web pages, subtitles, advertisements and so on. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] At pre...
