At CeBIT 2005 in Hannover, Germany, Sony exhibited a Blu-ray Disc-based computer recorder based on the next-generation optical disc specification.Because of its short wavelength, Blu-ray can be used to create more content on a single disc, so it is considered the technical standard for next-generation home recorders. Both the 3C and 6C alliances are pressing on the blue light. In the standard battle for the next generation of home recorders, China has been trying to establish its own standards. The EVD, which was independently developed by Beijing Shuguo Technology Co., Ltd., using red light recording technology, finally won in recent days after being mixed with HDV and HVD for more than half a year, and was listed as a national recommendation.
In January, Zhang Baoquan, chairman of Jindian Group, who actively promoted EVD to become a national recommendation, said in an interview with Tianji reporter: "The reason why the 3C and 6C next-generation standards did not come out, did not form a two-product, is to judge with their market. They think that the global market is going to rise sharply after 2005. China’s EVD standard is 'stunned.' If our Chinese standards are not fixed in time, China’s standard competition for the next-generation recorder market is Will lose the opportunity."
In the eyes of Zhang Baoquan, China's EVD is wearing grass shoes and competing with people who drive sports cars in Europe and America. If you can't gain an advantage in a short period of time, you will have to "get up early and catch up late." Sony's "Blu-ray Disc" computer recorder at CeBIT 2005 has sent a clear signal to the industry. Sony said that the laser head has reached the level of production, is studying efficient assembly methods on the production line, and is still verifying its mass production. .
Sony's showcased the "prototype" and "solid model", the prototype is the product for this demonstration. In the Sony demo, the HDTV image captured by the HDTV camera is stored in a personal computer and burned to a rewritable Blu-ray disc using the displayed prototype. After the BD-RE disc is taken out, it can be immediately Played smoothly on the player next to it. But the burning software was specially prepared by Sony for this demonstration.
The solid model is equipped with a laser head and signal processing board under development. The laser head structure is basically the same as that shown at "CEATEC JAPAN 2004" in October 2004, and is equipped with two objective lenses (Object Lens) for DVD/CD and Blu-ray Disc.
Signal Processing LSI can burn Blu-ray Disc, DVD, CD three discs. It consists of two chips, an RF amplifier IC and a signal processing LSI that is responsible for processing such as encoding/decoding. The basic verification of recording and playback has been completed.
