Description
Technical field
The present invention relates in the packaging program making of high standard definition three-dimensional television picture and text and data processing field, applied to high standard definition
Three-dimensional television picture and text pack the making and broadcast of program, more particularly to a kind of to carry out teletext packaging scene using data file
The method of switching.
Background technology
The application of picture and text system covers the every aspect of TV programme, including live news class program, studio interview
Class program, comprehensive gala evening class program, sports show class program, finance and economics information class program, meteorological GEOGRAPHIC ATTRIBUTES program and film electricity
Depending on the making and broadcast of acute program；The occasion of application it is existing it is live also have post-production, the post of application includes edit field, performed in a radio or TV programme
Room and broadcasting line.Virtual Studio Technology is Computerized three-dimensional graphics rendering technology in the most successful application model of field of broadcast televisions
Example.It is in news, physical culture and finance and economic program, to use the Computerized three-dimensional figure for being controlled by pick-up lens displacement that it, which is mainly applied,
The treatment technology such as shape technology and video keying produces virtual studio scene, by the host before camera lens and scene in kind and void
Intend scene to combine together；Efficiently solve time and Cost Problems that studio is built, it is possible to produce and more preferably regard
Feel effect, the ageing strong or bigger ground domain migration column that is particularly suitable for use in makes, and with computer graphical, image, regards
Frequency technology is continued to develop, in addition the compatibility and transition of radio, TV and film industries SD and high definition, and TV record and broadcast unit is carried to teletext
Requirement that is higher, updating is gone out.It is mainly reflected in abundant picture and text broadcast effect, specialized picture and text packaging product and high standard definition simultaneous
In terms of capacitive, image-text packaging system can be made to the document scene for needing to use and broadcasting in the prior art, pass through control
The need for instruction formulates the switching of each scene so as to meet during broadcast, in the system for only needing to broadcast scene, due to can not
To the edlin that is switched into of scene, therefore, it can not be modified to broadcasting order.
In inventor realizes process of the present invention, discovery has following defect in the prior art, in the prior art teletext
Play system is packed in picture and text packed file playing process, due to that can not enter to the episode sequence and control command of its inside
Row modification, it is thus impossible to be adjusted to the broadcasting order of scene, can only be generated by again in teletext packaging system
The mode of playing program realizes the scene handoff functionality of the above, therefore, increases the fabrication cycle of program, meanwhile, add system
Make cost.
