Video Acquisition

During the 1990s, with the rapid development of science and technology, the human production and working mode or life-style have the huge transformation. In the sports field, researchers and teachers have the aid of modern science and technology resources to improve various teaching methods , which do help to master the technical action and improve the sports level. In the practical application, these teaching methods is more effectual than conventional method in sports skill learning. Use exploratory study method to develop a suitable and low-price underwater video acquisition system for daily swimming teaching, which is also easy to be operated. The system is with the aid of underwater surveillance cameras to realize the technology of underwater swimming action film and real-time looked, and through the acquisition card timely playback and slow play function to intuitive realistically restore underwater technical movement dynamic change process. This research use the teaching experimental method,mathematical statistics and comparative analysis and so on, the students make two sets of different teaching contrast experiments, verify the effect of the underwater video acquisition system. Underwater video acquisition system in swimming teaching application, change the teacher explain demonstration and strengthen the students single teaching mode, formed by means of image data timely feedback video feedback teaching method.

Acquisition Task

The 3G wireless network video acquisition system based on the DM6446 is designed, which ARM side of DM6446 complete the main control functions of the system, then it calls H.264 video compression algorithm in DSP side of DM6446 through the Codec Engine, which greatly improves the efficiency of the system, and the RTP protocol control data transmission in the CDMA2000 network. The monitoring display terminal gets video resource by accessing the corresponding IP address. The experimental results show that the system designed completes wireless network video acquisition task safety and reliably, and the image is clear, also the video is coherent.
