The Design And Implementation Of Blu-ray Recorders Network Function

Blu ray recorders (Blue-ray Recorder), is a new generation of compact disc recorder after VHS tape recorder, DVD burner. Blu ray burner can be used to watch DVD, BD disk, can also accept the television broadcast signal, and the television program content to burn to BD-Blu ray disc. Compared with the DVD using650nm wavelength, CD using780nm wavelength red reader, Blu ray with wavelength405nm blue violet laser beam for read and write operations, which makes BD have greater storage space. BD large capacity storage space (single layer BD disk storage capacity of25G), possible and convenience for HD movies, games and large capacity of data storage and circulation, which greatly promote the development of high definition entertainment.But in the recent years, along with the FTTH project in China to promote, the speed has been greatly improved, the Internet video sites are more, many video sites provide SD, HD film. Can be said that the users gets the way is no longer confined to television and video, to obtain source also is a very important, efficient manner from the Internet video site.The hardware and software of Blu ray recorders are studied through the analysis of existing, the DLNA (Digital Living Network Alliance) standard and Realization of software and hardware design, network card, Ajax-CE network technology, video network interface technology, MoviePlayer network video file playback technology, with the development of the network function of Blu ray recorders appliance program interconnection function with the Internet video site and home LAN with DLNA. Finally, the whole system of network audio and video performance and electromagnetic compatibility is tested synthetically, and the Blu ray recorders for evaluation and verification.Comprehensive experiments to show, the network functional design in the Blu ray machine, support the DLNA1.5standard, can be viewed online "HuaShu video website" HDTV, SDTV programs. The experimental results can meet the original design requirements. Moreover, the experimen data show that, various indexes products reach the company’s agency within the standard, but also meet the network broadcast equipment industry standard.Through the study of this subject makes the Blu ray recorders network function strengthened expanded the way for users to access source, also facilitate the sharing of family computer and Blu ray recorders show the user home equipment. Give the user better, convenient audio and video appreciation mode.
