【摘要】：蓝光刻录机(Blu-ray Recorder),是继VHS磁带录像机、DVD刻录机之后的新一代光碟刻录机。蓝光刻录机可以用来观看DVD、BD碟片,也可以接受电视广播节目信号,并可以将电视节目等内容刻录到BD-蓝光碟片(Blu-ray Disc)上。同采用650纳米波长的DVD、以及采用780纳米波长CD的红光读写器相比,蓝光碟片则是采用的是波长405纳米(nm)的蓝紫色激光光束进行读写操作,这就使BD拥有更大的容量空间。BD所拥有的超大容量的保存空间(BD碟片单面单层存储容量可达25G),为高清影视节目、游戏等媒体的大容量数据存储与传播带来了可能,这大大促进高清媒体与娱乐事业的快速发展。可是近几年来,随着我国光纤入户工程的推进,网速得到了很大的提高,互联网上视频网站也风声水起,很多视频网站都提供了标清、高清的片源。可以说用户获取片源的方式不再单单局限于电视广播和碟片,从互联网视频网站上获取片源也是一条,人们乐于选择得非常重要、快捷的媒体数据获取方式。本课题通过分析研究了篮光刻录机现有的硬件与软件,通过对DLNA(Digital Living Network Alliance)标准的研究和网卡软硬件设计与实现技术的分析,以及通过Ajax-CE网络技术、视频网接口技术、MoviePlayer网络视频文件播放关键技术的研究,开发了具有家庭局域网内符合DLNA标准的家电节目互联功能与互联网视频网站互联在线视频观看的网络功能蓝光刻录机。论文的最后,对整个系统的网络音视频性能及电磁兼容性进行了综合测试,并对蓝光刻录机进行评估验证。全面的实验表明,本文在蓝光刻录机上开发设计的网络功能,支持DLNA1.5标准、可以在线观看“华数视频网站”上的高清、标清节目。实验结果能够达到了最初的设计要求。而且,实验数据表明,产品的各种指标均可达到本公司的企业内标准,同时也完全满足网络播放设备的行业标准要求。通过本课题的研究使得蓝光刻录机网络功能得以加强,扩大了用户获取片源的途径,也方便了用户家庭设备如家庭电脑与蓝光刻录机间节目的共享。给与用户更好、更便捷的音视频欣赏模式。从而也增加了本公司蓝光刻录机产品竞争力,开阔了更加广阔的市场前景。
[Abstract]:Blu-ray recorder (Blu-ray Recorder),) is a new generation CD recorder after VHS video recorder. Blu-ray recorder can be used to watch DVD,BD disc, also can receive television broadcast signal, and television programs and other content can be recorded on the BD- Blu-ray disk (Blu-ray Disc). Compared with DVD, with 650nm wavelength and red light reader with 780nm CD, the blue-purple laser beam with 405nm (nm) is used to read and write. This makes BD have a larger capacity space. BD has a large storage space (BD disc single-sided storage capacity up to 25G), which makes it possible for high-definition video programs, games and other media to store and spread high-capacity data. This greatly promotes the rapid development of HD media and entertainment. However, in recent years, with the development of optical fiber access project in China, the speed of the network has been greatly improved, and video websites on the Internet have also become popular. Many video websites have provided standard and high definition video sources. It can be said that the way that users get the source of the film is no longer confined to the television broadcast and disc, and it is also a way to obtain the source from the Internet video website. People are happy to choose a very important and quick way to obtain media data. By analyzing the existing hardware and software of the basket-light recorder, the research of the DLNA (Digital Living Network Alliance) standard, the design and realization of the hardware and software of the network card, and the Ajax-CE network technology, The video network interface technology and the key technology of video file playing in Movie player network are studied. A blue ray recorder with the function of home appliance program interconnection and internet video website is developed, which can meet the DLNA standard in home area network. At the end of the thesis, the network performance and electromagnetic compatibility of the whole system are tested, and the Blu-ray recorder is evaluated and verified. The overall experiment shows that the network function developed in this paper on the Blu-ray recorder supports the DLNA1.5 standard and can be used to watch the high-definition and standard programs on Huadu Video website online. The experimental results can meet the initial design requirements. Moreover, the experimental data show that all kinds of indicators of the products can meet the company's internal standards, and also fully meet the industry standards of network playing equipment. Through the research of this topic, the network function of Blu-ray recorder can be strengthened, and the access of users to the source of film is expanded, and the sharing of programs between users' home devices such as home computers and Blu-ray recorders is also facilitated. Give users better and more convenient audio and video appreciation mode. This also increases the company's blue-ray burner product competitiveness, broaden the broader market prospects.
