Problems solved by technology

The result is that digital TV receivers such as set-top boxes (servers of graphics systems) and all-in-one machines require a large amount of software and hardware custom development to enter every digital TV network, which makes it impossible for digital TV receivers to be sold in the horizontal market.

Embodiment Construction

[0023] In order to understand the technical content of the present invention more clearly, the following examples are given in detail. It is not intended to limit the invention to the examples. On the contrary, alterations and improvements are allowed within the scope of the intent of the present invention.

[0024] Such as figure 1 Described, the module distribution diagram of the machine-card separation graphics system. The graphics system XDC (X Display Control) is divided into two parts: the card end (client) and the set-top box (the server end of the graphics system), and the intermediate communication is completed through the UTI machine-card communication protocol based on the USB2.0 interface.

[0025] Such as figure 1 , a set-top box can support multiple cards at the same time, responsible for different value-added applications. The number of connected cards is limited by the maximum number of connections specified by the USB interface. The set-top box includes r...

Abstract

The present invention discloses a machine card separation figure system base on a C / S structure, which belongs to the digital television and figure system display technology field. The system comprises a machine card separation system and a figure system. The machine card separation system comprises a digital television receiver, a big card, and a machine card communication interface. The digital television receiver is used for the user operation such as the button receiving process, and the control of the figure output display. The big card comprises a separate CPU, which is used for the digital television application such as the condition receiving and the realization of the electronic program guide. The machine card communication interface is used for the transmission of the machine card separation protocol. The figure system comprises a figure system server of the digital television receiving terminal, a figure system client of the big card terminal, and a figure system communication protocol transmitted on the machine card communication interface. The utility model realizes the function of dividing the digital television application such as the condition receiving and the electronic program guide from the digital television receiving terminal to the module terminal, and thereby the purpose that the digital television has no connection with the difference of the digital television is reached.

Description

field of invention [0001] The invention relates to a machine-card separation graphic system based on C / S structure. The invention belongs to the technical field of digital TV and graphic system display. technical background [0002] Due to the lack of unified norms in the process of digital TV service platform construction by digital TV network operators, there are huge platform differences and digital TV receiver function differences. These differences include conditional access and electronic program guides and various other digital television applications. The result is that digital TV receivers such as set-top boxes (servers of graphics systems) and all-in-one machines require a large amount of software and hardware custom development to enter every digital TV network, which makes it impossible for digital TV receivers to be sold in the horizontal market. . [0003] In order to solve this problem, the machine card separation technology must be adopted. Machine card s...
