Abstract
The multi-media television card (MTVC) makes the computer increase one function, that is the TV program and videotape program can be received by utilizing VGA displayer. The operation of computer is not affected and the switch over can be conducted by remote controller at any time. The digital treatment makes the TV picture resolution come up to 1050 X 625. The computer can be used to receive and store the viewdata.
Description
Multi media television card (MTVC) is to make computer increase a function, promptly utilizes the High Resolution Display-VGA display of computer to show television image, video program.
Because the demonstration of TV and the display of computer are inequality fully, multi media television card has successfully been realized the conversion of TV signal to Computer signal.
The VGA monitor resolution of computer has reached 1024 * 768, and TV signal has only 350 * 300 lines.Multi media television card has adopted the described point technology of original creation, has inserted two points in the horizontal direction, adds a point in vertical direction, and the TV signal that multi media television card is produced reaches 1050 * 625 resolution.
The form of multi media television card original creation:
1. remote controller is introduced computer operation;
2. do not take the resource of computer;
3. do not influence any program of computer run, can switch at any time;
4. high definition shows;
5. computer is received and the storage broadcast videography, show its content at any time.
