Based On Igrs Protocol Hdtv

This paper presented a design of High-Definition TV based on IGRS protocol, This TV can get the Multi-media things that is shared on PC, it also can play them so people can enjoy this on TV having big Screen.Nowadays, Chinese defined the IGRS (Intelligent Grouping Resource Sharing) standard, which is the first standard in 3C domain in China, and it will be the first international standard in 3C domain soon. This paper introduced the background and the significance of defining this standard. The contents of this technical standard are being presented in detail also. Taking use of the opportunity of High-Definition media becomes more and more popular; this paper uses this standard in High-Definition media playing. So, a design of High-Definition TV using this standard is available in this paper, which includes the whole design draft, the hardware design and the software design in detail. The hardware design includes power-supply designs, memory and storage designs, network designs and USB interface designs. Software design includes network function design, media player design and user interface design, besides this, hardware abstract layer is designed to make the software more independent from hardware. The network function is designed basing on the IGRS stack and IGRS AV Profile. Media player can play most High Definition formats movies including network media files and local media files. The User Interface designed a GUI system on the uClinux, it can make this system response the user's demands.Through the test, it works that this designing can extremely fit the requirement which is defined before. It is a success of applying the IGRS standard into an actual product. This will be very helpful during the IGRS Standard becoming the real fact standard in 3C domain. It also can do a big favor in accelerating the development of national industry in 3C domain.
