PCI (Peripheral Component Interconnect) interface applied to display terminal of digital multimedia and implementation method of PCI interface

Abstract

The invention discloses a PCI (Peripheral Component Interconnect) interface applied to a display terminal of a digital multimedia, comprising PCI slots and PCI slot interfaces matched with the PCI slots, wherein the PCI slots are provided with pins, the PCI slot interfaces are also provided with pins, the pins on the PCI slot interfaces are distributed on a top layer and a bottom layer, the pins of the PCI slots and the PCI slot interfaces follow a certain pin connecting definition, and the PCI interface is arranged at input and output interfaces of the display terminal of the digital multimedia. The display terminal of the digital multimedia with the PCI slots which follow the connecting definition is used as a mother machine. The PCI slots are provided with the PCI slot interfaces matched with the PCI slots, so that the PCI slot interfaces are inserted into the mother machine to be used. According to requirements, the PCI slots following a certain pin connecting definition are inserted with correspondingly required expanding modules to realize the function expansion. The invention has the advantage of providing a universal open type streaming media interface form.

Description

technical field [0001] The invention relates to an interface, in particular to a PCI interface applied to a digital multimedia display terminal and its realization method. Background technique [0002] With the development of science and technology, various digital multimedia display terminals are used more and more widely. With the continuous increase of people's demand for functions, the traditional way of simply integrating all functions in one digital multimedia display terminal has become backward. Therefore, people have been looking forward to a digital multimedia display terminal with expandable functions, which requires an open streaming interface, which can be used to expand various functional modules. [0003] Although the PCI interface is widely used on computers, due to the fundamental difference between computers and digital multimedia display terminals, for digital multimedia display terminals, due to the changes in the positions of various pins on the PCI int...

AI Technical Summary

Problems solved by technology

[0003] Although the PCI interface is widely used on computers, due to the fundamental difference between computers and digital multimedia display terminals, for digital multimedia display terminals, due to the changes in the positions of various pins on the PCI interface, the performance of the whole machine will be affected. The impact is relatively large, that is, the unreasonable pin arrangement will cause electrical interference between them, and ultimately affect the use effect. Therefore, the distribution of PCI interface pins needs to be analyzed and practiced in many aspects, and the workload is large. The test period is long, so there has been no uniform standard in the industry

Various manufacturers may use different interface forms, or the interface forms are the same, but the pin definitions of the interfaces are different, which makes it difficult for products from different manufacturers to cooperate with each other.

Once a consumer buys a certain product to use as a master machine, he can only purchase the expansion module of the manufacturer for use, which has great limitations.
