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
The invention belongs to technical field of digital television set-top, be specifically related to collocation method and the system of DLNA program contents data in a kind of digital TV set-top box.
Background technology
Digital TV set-top box is a kind of conversion equipment that digital television signal is converted to analog signal, and it is reduced into the signal that general television set can be play demonstration to image and the voice signal decoding through digitalization compressed.Current digital TV set-top box has become a kind of embedded computing equipment, has perfect real time operating system, and powerful CPU computing capability is provided, be used for coordinating controller top box each several part hardware facility, and provide the Internet, DLNA media the multiple new function such as to share.Generally need to receive the partial function configuration that the MTA configuration file is realized set-top box in the set-top box start-up course.
The full name of DLNA is DIGITAL LIVING NETWORK ALLIANCE, is intended to realize the media sharing functionality between personal terminal.The DLNA functional module generally comprises DMS, DMP, DMC and DMR.Wherein, the DMS full name is digital media server Digital Media Server, is responsible for mainly that media obtain, record, storage and output function.DMS module among the general integrated DLNA of digital TV set-top box, the DMS module is responsible for the DLNA user terminal program and the bibliographic structure that can watch is provided.
At present, the mode that the DMS module obtains the TV programme catalogue data among the DLNA in the digital TV set-top box generally has following two kinds:
Method one: the DMS module software of DLNA software solidifies the program contents data when mounted, and carries out configuration and the renewal of program contents by the mode of DMS module software updating.Advantage be realize comparatively simple.Shortcoming is:
1, the configuration of DLNA program contents data is related with module software updating, the update efficiency of program contents data is lower;
2, operation easier is larger when realizing number of different types DLNA program service, need to prepare for the user software of different editions.
Method two: in digital TV set-top box MTA configuration file, increase DLNA program contents data configuration, program information and the bibliographic structures such as configuration program place frequency, service, television program icon information, Internet video path can carry out the config update of TV programme catalogue by the mode of upgrading the MTA configuration file.Advantage is to realize at the operation front end configuration management of DLNA program contents data.Shortcoming is:
1, significantly increases the size of MTA configuration file, thereby reduced the receiving efficiency of describing other functional configuration information in the MTA configuration file;
2, all allow the MTA configuration file be described TV programme directory content configuration and functional configuration, can't realize the configuration of content and functional independence, reduced the flexibility of configuration, and easily funtion part is produced misoperation during update content, have potential safety hazard;
3, in the reality operation, the MTA configuration file generally carries out unified management by the business operation support system (BOSS) of operator, and the method needs to upgrade the configuration file of BOSS system relationship when upgrading DLNA TV programme directory content, operation is comparatively complicated, has handling safety hidden danger.
Summary of the invention
For the defective that exists in the prior art, the object of the present invention is to provide collocation method and the system of DLNA program contents data in a kind of digital TV set-top box, realize rapid configuration and the renewal of DLNA program contents data.
