Claims (1)

[Scope of Claim for Utility Model Registration] 1. It relates to a laser radio function expansion controller, which mainly includes a micro processing device, a connection interface of a home computer, a TV connection interface, and a laser radio connection interface, and the said micro The processing device controls the laser radio, reads the data such as audio, graphics, and documents on the CD-ROM, and processes the data sent to the home computer or TV, thereby reading the visual representations and vocalizations. The characteristic of something is that it achieves integrated superpowers. 2 Utility Model Registration Claims A controller as described in paragraph 1, in which the microcomputer processing unit includes: one central processing unit; one I/O parallel input/output interface; A set of transmitting commands to a central processing unit, executing operations related to the commands, and reading laser risk audio, documents, and other materials using an I/O parallel input/output interface control laser radio; A storage and retrieval memory with the aircraft; one direct storage and retrieval circuit for storing CD risk index material read by the laser radio in the aircraft storage and retrieval memory, as well as for timely retrieval of this material from the central processing unit. Check it out,
It is transmitted to the external computer through the I/O parallel input/output interface to achieve CD-ROM functions such as document index matching; it is a single color pictorial circuit, and it is used to transmit it to the external computer. Its characteristics include displaying the graphical material on the CD risk obtained directly from the memory storage and retrieval circuit, stored in the aircraft storage and retrieval memory, and further processed by the central processing unit. 3. The microprocessing device mentioned in Claim 2 of the Utility Model Registration Claim, in which the direct memory storage/retrieval circuit utilizes a timing signal generator controlled by the apparent machine code of the central processing unit,
It is characterized by generating clock pulses for the central processing unit based on the synchronization signal from the record disc, and at the same time controlling the changeover switch for storing or retrieving CD materials in the aircraft's storage/retrieval memory.
