Description
Technical field
The present invention relates to field of broadcast televisions, particularly relate to a kind of digital broadcast television system, set-top box and boot-strap menu display process.
Background technology
Digital broadcast television system comprises front end system, transmission network and set-top box.Set-top box is passed through the programme signal that transmission network receiving front-end system sends, and outputs to display unit after programme signal is handled and shows that described programme signal is web page signals or vision signal, and described display unit is TV or other display terminal.In field of broadcast televisions, typical transmission network is hybred fiber-coax (HFC) network.
During set-top-box opening, its software and hardware initialization needs a period of time, and initialization time is approximately 10 to 20 seconds.During this period of time, normally show one section start-up picture on TV, image content is welcome message or advertisement.The start-up picture data are kept in the flash memory (flash) of set-top box, and during start, set-top box is taken out the start-up picture data from flash, and output to TV after described start-up picture data are handled and show.According to service needed, operator needs often to upgrade start-up picture, front end system sends to the user side set-top box by transmission network with the start-up picture data, and set-top box is kept at the start-up picture data of upgrading among the flash, and just can show new start-up picture when starting shooting next time.
There is following shortcoming in boot-strap menu display process in the prior art:
1. start-up picture can only Show Picture, and can not show animation or video.
Because the start-up picture data are kept among the flash, are subjected to the capacity limit of flash, it can only preserve image data, can not preserve animation data or video data, thereby the start-up picture that shows on the TV also can only be picture.
2. when start-up picture being upgraded, has certain mortality.
In renewal process,, upgrade mortality generally about 5% because update software is made mistakes, signal disturbs, shut down in the ablation process etc. all can cause and upgrade failure.
3. easily flash is caused the hardware infringement.
During start or carry out can reading or writing flash when start-up picture upgrades, frequent flash is read and write can cause its hardware infringement, influences the operate as normal of set-top box.
4. can interrupt user's TV watching.
In the start-up picture renewal process, the more new data that set-top box receiving front-end system sends, thereby can not normally receive other program data, cause user's TV watching to interrupt.
Summary of the invention
