A design realization method and device for dynamic change of start-up image

Abstract

The invention relates to a method for designing open picture dynamic switch, and relative device. Wherein, it comprises that EPG produce server, sender, digit TV network and receiver, remote controller, set-top box, and TV; the set-top box dynamic memory has dynamic exchangeable data memory area, to separate the application program data and open picture format data of set-top box, to avoid program code and memorization in single-transmission digit TV network and general set-top box, to freely exchange the start picture format data. The invention can realize the single-direction transmission network at digit TV broadcast, at the general set-top box, without changing program code and refreshing the application program.

Description

Technical field: [0001] The present invention belongs to the field of digital television, and particularly relates to a method and device for designing and implementing the dynamic replacement of the start-up screen, that is, a method for updating the start-up screen of the local set-top box by dynamically receiving the data sent by the front end of the TV transmission network system by the digital TV set-top box, in particular to The transmission of front-end data and the analysis and application of data by the local terminal set-top box. Background technique: [0002] In the past, the set-top boxes of various manufacturers burned the image of the start-up screen as a program resource into the set-top box. When customizing different start-up screens for different operators or different set-top box manufacturers, the program of the set-top box has to be updated, which is very inconvenient. Therefore, most of the current set-top boxes are basically the same startup screen onc...

Problems solved by technology

The entire set-top box program is mainly packaged in the form of DSMCC data broadcasting, and then a special service is used for MPEG-2 data transmission. In this way, it is only for updating a boot screen instead of updating software codes, which requires a relatively large number of twists and turns. The program code is sent together, and the receiving end has to go through a complete CRC32 check. Because the entire data volume is relatively large, it is divided into many blocks for transmission, so it is more troublesome from the sending and receiving applications to the terminal, and once downloaded When it fails, the old program cannot be started at the same time during the new download process, unless the download is abandoned and the old program file is loaded

In addition, CN1275740A discloses a data update method for computer network, but the two-way symmetry of computer network and the convenience of computer operation cannot be used for digital TV networks and common set-top box applications with only one-way transmission broadcast mode
