Chip giant, two-way interactive digital television seven main attack technology – chips, digital TV,
Article by hi joiney
A radio and television operators in China have concluded a few years ago the industry to do an analog TV digital, two years of doing two-way digital services, while the next few years to do interactive business scale.
As digital STB The most upstream industrial chain link, chip companies keep a close eye of the value chain leading??? Operators, to determine their current R & D focus and direction of future technologies.
China 1 Radio and TV Operators have concluded in previous years in the industry to do an analog television digital, digital business the past two years is doing a two-way process, and to do the next few years, large-scale interactive business.
This statement summarizes the current work of the Centre operators, chip company raised for the advancement of technology focus. Therefore, this year CCBN During the exhibition, the chip company introduced the theme of two-way interaction, at the same time seven technology update:
First integrated rich interface chip is also the basic conditions for return. One Ethernet, USB and Cable Modem The interface is suitable for the Chinese market. However, only a few enterprises of these ports are integrated into a single chip.
Second, chip processing speed. To run a variety of interactive services, the main chip set-top box processing power is becoming increasingly important. Currently HD STB’s processing speed up to 800MIPS ~ 1000MIPS. Third, the operating system to Linux
conversion. Previously, many chip companies have developed their own proprietary embedded operating system, but these proprietary systems ability to support interactive services is relatively weak. Therefore, some chip companies are converting to the Linux platform.
Fourth chips will be chip platform is the underlying business drivers and the upper application layer software to do more clearly defined, so that customers can keep adding new applications.
5 is support for Java technology. Since online games are promising, some companies will also migrate to Java virtual machine chip platform. Of course, if they can solve complex business problems, develop value-added services for our customers greater convenience.
6 is support for interoperability standards. Chip companies are considering supporting such a variety of DLNA interoperability standards.
7 is support for multiple decoding formats, to support a variety of channels from content sources.
From the above point of view, not a chip company in the industry will do its best products, so we still much work to be done.
ST Greater China digital consumer Electronic And encryption products division marketing manager Qiu JindeTo provide a full range of interactive services platformSense, the Chinese operator of innovative value-added services than the foreign countries to advanced. Therefore, the rapid growth of the market confidence.
STMicroelectronics (ST) for the interaction Digital TV Market from MPEG2 SD to H.264 HD’s full range of products. The latest products are STi5197, STi5205 and STi7105. Their capacity is high, you can run all the software.
The PC, consumer products and Communicate Product link the concept of the family network, ST has recognized the importance of the market, our STi7105 can be applied to home network media server. We also have for the wired, wireless, EoC (Ethernet signal transmitted through the coaxial cable) application development into new products being produced. We identified a common software API, support for customer cable, IP, satellite and terrestrial digital TV, development of products in different markets.
Machine in one respect, the market is driven by two main forces. On the one hand, all countries have developed their own standards, mandatory or optional in the local implementation. Those who have long been converted to digital television broadcasting countries, when their market is ripe for one machine on the strong demand there. On the other hand due to globalization, the ongoing global market integration of multimedia content. Market demand for large-scale digital signal chip solutions to enable the price of the program with those analog functions closer. Thus, in addition to tuner and a small portion of the software stack, the TV platform has become a common platform. And this platform has more connections, because TV is no longer a closed system, it has a richer, more friendly and more intelligent user interface. ST in the acquisition of Genesis, after the company launched a new product has the following features: a more open software stack, green energy, connectivity, stronger, better quality, interfaces, more (including 3D support), at the same time, application also more abundant.
Us from the outset to become a member of AVS is the first to announce and production support H.264/MPEG2/VC1/AVS vendors. We support the AVS (Audio Video Coding Standard in China own) approach to support other independent standards development in China. We can serve as partners, technology providers, IP licensors to support China’s own standards, and commercial and technical cooperation with partners to achieve win-win objective.
Fujitsu Microelectronics (Shanghai) Co., Ltd Product Manager, Bu ChunThe Java virtual machine migration to the chip platform is the trendJava games, karaoke OK, TV banking, TV shopping, will have more users. Experience from abroad, the combination of chips and mainstream middleware is very important. Fujitsu Microelectronics
that high-definition, interactive digital TV will be the development of a trend. As the main chip set-top box provider, in addition to the hardware platform with the necessary two-way interactive protocol stack and drivers, but also interactive applications to help customers build the necessary software platform. For example, in order to facilitate the client to carry out an interactive game application, we will migrate to chip Java virtual machine platform, and passed Sun’s TCK certification, which is currently the only company in the chip market.
As chip companies in the software platform, we consider to provide a complete and diverse, alternative solutions to meet diverse customer applications. In addition, foreign experience, we and the Chinese mainstream of middleware vendors have established strategic cooperative relations, constantly adding new user-friendly application.
In one machine, the last year, we launched for cable, terrestrial, satellite broadcasting market, SD / HD solutions for one machine. At present one machine shipped mainly in Europe and North America, while China’s domestic market is just one machine starts. We believe that over time, China’s domestic market share of one unit will increase, and this one machine which will account for a large proportion of high-definition.
