基于视频推荐技术的无线网络视频服务器设计

无线网络视频服务器中视频推荐技术已成为重要技术之一,视频推荐技术是为了用户在使用无线网络是视频务器时,更快的找到感兴趣的视频；采用当前方法对用户进行视频推荐时,未考虑用户的兴趣偏好是否随着时间有所变化,使视频推荐出现偏差；为此,提出一种基于视频推荐技术的无线网络视频服务器设计方法；该方法首先使用无线网络视频服务器硬件部分的MPEG-4进行视频数据采集,并对MPEG-4采集的视频数据进行整理；在由软件部分把采集到的视频数据储存到缓冲区,进行视频缓冲,并建立视频数据队列进行视频数据输送；以计算无线网络视频的相似度来搜索相近视频,将搜索到的视频与目标用户观看过的视频进行对比,对比相似度越接近1,则说明用户对推荐视频感兴趣的几率大,反之越接近-1用户对推荐视频越不感兴趣；此计算方法能有效的从海量视频数据中快速的搜索出目标用户感兴趣视频；实验结果表明,将视频推荐技术应用到无线网络视频中可以迅速准确的搜索出目标用户感兴趣视频。

Design of Wireless Network Video Server Based on Video Recommendation Technology

Wireless network video recommendation technology has become one of the important technology, video technology is recommended to the user is the video server in the wireless network, quickly find the interested video. Using the method of video recommendation to users, without considering whether user preferences along with the change of time, the emergence of video recommendation deviation. Therefore, we proposed a wireless network video server design method based on video recommendation technology. The method uses a wireless network video server hardware MPEG-4 video data acquisition and video data collected by MPEG-4 were collected by software. The part of the video data collected is stored in the buffer, video buffer, and a video data queue for video data transport. In calculating the similarity of wireless network video to search for similar video, video search and target users watch video on the contrast ratio, similarity is closer to 1, the probability of the user interested in video recommendation, and more close to the -1 users of the recommended video is not interested in. This method can fast from the massive video data in the search for target users interested in video effectively. The experimental results show that the video recommendation technology is applied to the wireless network video can be quickly and accurately. Out of the target audience interested in video
