Description
Technical field
The present invention relates to the household appliances field of television, particularly utilize the high speed processor and the big capacity memory storage TV multidate information of television set and can carry out method and the television set that repeats to browse.
Background technology
Existing television set can only be realized the real-time broadcast of TV signal,, need carry out in real time TV information and retain for example when the wonderful of telephone number, goal and highlight when spectators see information of interest, be used to repeat to browse its content.For this purpose, the TV images replication technology that provides at present, although it is various informative, comprise that various video recording equipments are (as the VTR video tape recorder of early stage employing tape media as recording medium, but adopt the PVR personal video recorder of RAD random access disk media such as HDD hard disk drive and rewritable DVD digital versatile optic disk as recording medium) and some video image transcribers, some technology even with Pictur recording device and television internal, but its basic scheme mainly also is to use independent controller to control image-reproducing means work, finish storage and representational role to the TV multidate information, the control chip of television set itself does not participate in recording the process control with the reconstruction of image.
Early stage the DVR television product, with the VIDEO signal storage of television set to hard disk, what adopt also is standalone module control, television set only provides power supply and VIDEO signal, its memory capacity depends mainly on the hard-disc storage space, other work all is to realize that by the DVR module module of television set does not participate in controlled function.
Although DVD digital versatile optic disk and HDD drive hard disk, can finish the storage at random of big capacity dynamic image data, its capacity is big, the advantage of the length of time is demonstrated fully, and, as if do not have other schemes to participate in storage, the more simple possible of recording, replay of control TV information directly than television set in the face of storage, the reproduction scheme of TV multidate information.
Along with the continuous upgrading of television set and the continuous enhancing of electronic devices and components function, television set trends towards the multimedia direction to be developed, television set can be done the simple work of having only microcomputer to handle before some, especially the CPU microprocessor of television set rises to after 32 by 8, be aided with the big capacity internal memory of 256M, make television set self finish with television signal be converted into storable digital information and in due course the technical scheme replayed of machine may realize.
Summary of the invention
One of purpose of the present invention is to provide a kind of method that realizes television set grabgraf and video recording, television set is participated in the storage/Play Control of TV information directly, the separate controller that does not re-use other removes to control image-reproducing means can realize TV information storage and representational role, and the function of television product is enhanced.
Another object of the present invention is to provide a kind of television set with grabgraf and recording function.
For this purpose, technical scheme provided by the invention, realize that the method for television set grabgraf and video recording may further comprise the steps:
Operation control sends intercepting TV signal request instruction to television set CPU microprocessor;
CPU microprocessor control TV information interceptor intercepting TV digital signal;
