Abstract

The utility model relates to a television card with MINI-PCI interface. The utility model has a signal receiver capable of receiving a plurality of television signals at the same time. The signal receiver sequentially transmits the television signals through signal amplifier, signal processor and signal decoder. After processing, demodulating and decoding, the television signals are transmitted to host computer via the MINI-PCI interface for displaying. The television card with MINI-PCI interface can receive various television signals at the same time without using MINI-PCI television card, thus the slot number for MINI-PCI at host computer can be reduced.

Description

The TV card of tool MINI-PCI interface

Technical field

The utility model is a kind of TV card of tool MINI-PCI interface, especially refer to utilize the MINI-PCI interface to transfer to the TV card that host side shows, receiving digital television signal, simulated television signal and audio-visual signal show simultaneously for they, by this can be under the situation that does not increase the MINI-PCI TV card, make the TV card of MINI-PCI interface receive different types of television signal simultaneously, and reduce the use amount of the MINI-PCI slot of host side.

Background technology

Television set is since coming out, by early stage iconoscope black-and-white TV, color-picture tube TV, develop till now LCD TV and plasm TV gradually, the display effect of TV has marched toward high image quality, good, bright epoch of contrast, and the channel of TV has been marched toward the boundary of channel nearly hundred and the signal transmission means of TV by early stage very few channel, also along with the change in epoch, and march toward digitized transmission means.

Along with starting broadcasting of Digital Television, the user is for the receive mode variation more of TV programme, no matter be the wire/wireless TV of simulation or the wire/wireless TV of numeral, all be not to use the person can be according to the selected selection of environment, so generally when TV reception, most users sees through television reception to watch wired or wireless analog or digital television signal.

Yet computer or mobile computer also are one of instruments of TV reception, see through computer or mobile computer and connect TV box or TV card, television signal receives via TV box or TV card, after demodulation and the decoding, reach on the screen of computer or mobile computer and play, but general TV box or TV card are when receiving television signal, simulated television signal that only simple reception is wired or wireless or Digital Television signal (wired simulated television signal, the wireless simulation television signal, the cable digital TV signal, the radiovision signal), can't receive different types of television signal simultaneously, and general user is for saving the interior space and desk-top space, greatly more than being inserted with TV card in the main frame, and TV card is to see through MINI-PCI (MINI-Peripheral Component Interconnect) interface to be connected with computer main frame panel mostly, so when desiring to watch the TV programme of Digital Television signal and simulated television signal simultaneously, then must install different TV card respectively.

Because the slot of general main frame is limited, and adapters such as display card, sound card, network card have been equiped with, then do not have unnecessary slot and install the TV card of plural different size, mobile computer then is to see through MINI-PCI interface slot to plug TV card, because mobile computer is for fear of the size restriction of volume, so additional MINI-PCI slot is also limited, so can't plug a plurality of MINI-PCI adapters simultaneously.

Therefore, how to make the TV card of computer or mobile computer can have the television signal that receives multiple kenel, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

Main purpose of the present utility model is to provide a kind of TV card of the MINI-PCI of having interface, this TV card can be connected with computer or mobile computer, then signal receiver and audio-visual signal receiver are after receiving television signal and audio-visual signal, can see through the MINI-PCI interface transfers in computer or the mobile computer, and by playing in computer or the mobile computer, so can be under the situation that does not increase the MINI-PCI TV card, make the TV card of MINI-PCI interface receive different types of television signal simultaneously, and reduce the use amount of the MINI-PCI slot of computer or mobile computer.

Secondary objective of the present utility model is that this TV card is provided with signal amplifier, after television signal receives, can television signal be carried out signal processing and signal optimization etc. through signal amplifier, then signal processor and signal decoder receive the good television signal of signal quality, and the television signal after demodulation and the decoding will have good rating quality.
