基于DLNA的音频广播系统的设计与实现
|
摘要
随着信息产业的高速发展,在国内外音视频技术迅猛发展的基础上,各种家庭网络设备层出不穷,特别是音频设备在日常生活中的使用更是普遍,传统广播系统的局限性越来越无法满足人们的需要,设计能够实现局域网内的资源共享的智能广播系统已经成为未来发展的必然趋势。以DLNA数字家庭网络为基础,从分析UPnP协议的模块出发,利用Linux嵌入式开发平台设计一套完整的音频广播系统。
With the rapid development of the information industry, various home network devices are emerging on the basis of the rapid development of audio and video technology at home and abroad. Especially the use of audio equipment in daily life is more common, and the limitations of traditional broadcasting systems are unable to meet people's needs. Designing an intelligent broadcast system which is capable of realizing resource sharing within a local area network has become an inevitable trend in the future.Based on the DLNA digital home network, a complete audio broadcasting system is designed with the UPnP protocol module and Linux embedded development platform.
