Method and system for configuring dlna program catalog data in digital TV set-top box

Abstract

The invention discloses a method and a system for configuring DLNA (Digital Living Network Alliance) program catalog data in a digital television set-top box. The method comprises the steps of: firstly, setting a DLNA program service ID (Identifier) and an URL address of a front-end detection update server for program catalog data in an MTA (Multimedia Terminal Adapter) configuration file of a digital television set top box subscribing relevant DLAN functions, downloading the MTA configuration file when the set top box is started, and checking whether the set top box stores the DLNA program catalog data or not; if not, applying to the front-end detection updating server for downloading the DLNA program catalog data corresponding to the service ID according to the DLNA program service ID, and downloading data from a DLNA program catalog data download server; and if so, checking whether the stored DLNA program catalog data is the latest version, and if not, downloading the latest DLNA program catalog data and updating the DLNA program catalog data. According to the method and the system, disclosed by the invention, the flexibility, operability and efficiency in configuring the DLNA program catalog data can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of digital TV set-top boxes, and in particular relates to a configuration method and system for DLNA program catalog data in the digital TV set-top box. Background technique [0002] A digital TV set-top box is a conversion device that converts digital TV signals into analog signals. It decodes and restores digitally compressed image and sound signals into signals that can be played and displayed by ordinary TV sets. The current digital TV set-top box has become an embedded computing device with a complete real-time operating system and provides powerful CPU computing capabilities to coordinate and control various hardware facilities of the set-top box, and provide interactive networks, DLNA media sharing, etc. new features. During the start-up process of the set-top box, it generally needs to receive the MTA configuration file to realize some function configurations of the set-top box. [0003] The full n...

AI Technical Summary

Problems solved by technology

[0006] 1. The configuration of DLNA program directory data is associated with module software upgrades, and the update efficiency of program directory data is low;

[0007] 2. It is more difficult to operate when implementing various types of DLNA program services, and different versions of software need to be prepared for users

[0009] 1. The size of the MTA configuration file is greatly increased, thereby reducing the efficiency of receiving other function configuration information described in the MTA configuration file;

[0010] 2. Both the content configuration and function configuration of the TV program directory are described by the MTA configuration file, which cannot realize the independent configuration of content and functions, which reduces the flexibility of configuration, and it is easy to misuse the function part when updating the content, posing a security risk;

[0011] 3. In actual operation, the MTA configuration file is generally managed by the operator's business operation support system (BOSS). This method needs to update the configuration file associated with the BOSS system when updating the content of the DLNA TV program catalog. The operation is more complicated. There are operational safety hazards
