Method and processing output signal from computer and television device and Apparatus

TECHNICAL FIELD The present invention relates to a television receiver and a computer, and more particularly, to a method and apparatus for processing output signals of a computer and a TV receiver.

Recently, with the development of a computer, an apparatus for watching television using a computer has been developed. Looking at a television viewing apparatus using a conventional computer, it is possible to watch a television by attaching a television receiving card of a PCI or USB type to the computer. Peripheral Component Interconnect (PCI) is a local bus that provides a data path for data transfer at high speed by directly connecting the central processing unit (CPU) and peripheral devices. It is adopted in most PCs. In addition, the USB (Universal Serial Bus) aims at the commonization of an interface for connecting peripheral devices, such as keys, mice, printers, modems, speakers, etc., of different specifications, to a personal computer (PC). Therefore, by using USB, all peripheral devices are connected to the same connector without any software or hardware setup when connecting peripheral devices to the PC. This greatly reduces the number of ports and makes installation easier. There is an advantage that miniaturization is possible.

However, if the computer is watching a broadcast with a TV receiving card mounted in a PCI or USB method, the computer should be turned on to run the operating system and then run the program developed for the receiving card to watch the broadcast. In addition, in the case of HDTV (high definition television) receiving cards, broadcasts should be mostly viewed using softly compressed data.

Therefore, according to the prior art, since the user must always turn on the PC when watching television to execute the program, inconvenience in use and unnecessary power consumption occur. In addition, since a program for viewing a broadcast is software, a conflict or compatibility problem may occur with other devices, and channel switching is slower than that of a general television. In addition, since most of them are limited to the monitor, image output is made, and the procedure is complicated to be used by a user who is not familiar with a computer. In addition, in the case of HDTV, since the computer requires more than a certain SPEC performance, and mostly broadcasts using softly compressed data, the CPU occupancy increases, which may affect the operation of other programs.

Accordingly, in order to solve the above problems, an object of the present invention is to independently perform the functions of the computer and the television, respectively, and to process the output signal of the computer and the TV receiver capable of watching television without the execution of the computer and its To provide a device.
