摘要：With the rapid development of electronic information technology, traditional interpretation pattern in exhibition building and museum is developing towards digitization, information, intelligence, automation and multi functionality. A novel intelligent video playback system, which can be widely used in tourism and exhibition, is provided in this paper. The video playing system consists of radio frequency identification (RFID) module and video playback module. The novel system integrates advanced RFID technology, embedded control technology, and video playing technology. The RFID module identifies visitors, and selects the language and other information. The main chip of the RFID module card reader is MF RC522 which is working in frequency bands of 13.56 MHz, and the microcontroller of the module is Atmega8. C programming language was used to program microcontroller in order to realize the function of automatically reading. The video playback module realizes the function of playing video files and controlling RFID module. On the hardware design of the video playback module, the S3C2440 chip with ARM920T core was selected as the main control chip. The video playback module was developed by WinCE developing platform. Related drivers and application software were developed to control card reader, select language and to play the video file. The intelligent video playback system has several advantages such as: good real-time property, high portability and easy in maintenance. The system has its application prospect in exhibition and tourism.
