DiiVA digital high-definition interactive transmission interface technology and development trend
(Summary description)DIIVA is a digital high-definition interactive transmission interface technology that supports video bandwidth up to 13.5Gbps, supports mixed channel bandwidth of more than 2Gbps in total, can do bidirectional data and audio transmission, and also supports HDCP 2.0 (high-bandwidth digital content protection technology) and DTCP- IP (Content Protection for Digital Transmission over Internet Protocol). Data types transmitted can be streamed simultaneously, including uncompressed high-resolution AV formats for existing and future applications, USB (Universal Serial Bus), Ethernet, device control commands, and more. The DiiVA specification includes a transport layer and a network layer, allowing video, audio and data packets to safely reroute from any source to any display in a DiiVA home network. In addition, the DiiVA specification will provide network connectivity and charging capabilities for mobile portable devices.

Development history: With the rapid development of digital technology and network technology, color TV will become the main carrier of "three networks integration", "4C integration" and digital home industry. In the face of new opportunities and challenges in the color TV industry, under the guidance of the Ministry of Industry and Information Technology, the China Electronic Video Industry Association organized the domestic backbone color TV enterprises to move from competition to alliance, especially in joint innovation and standard formulation towards building a win-win situation Key steps have been taken in the coordinated development of the new industrial pattern. After three years, the color TV backbone enterprises have jointly developed and promoted the key technologies and standards of digital high-definition interactive interface (DiiVA) in the digital home field, creating new competitiveness for the color TV industry in the transformation stage, and upgrading digital home applications for global consumer electronics. make a positive contribution.
Technology: DiiVA (Digital Interactive Interface for Video & Audio) is supported by the Ministry of Industry and Information Technology, initiated and led by Chinese key enterprises, actively participated by internationally renowned enterprises, has independent core intellectual property rights, and has revolutionary innovation achievements. The leading digital high-definition interactive interface technology in the field of consumer electronics. Because DiiVA interface can not only realize two-way transmission, but also transmit compressed and uncompressed data, and has network transmission function, it will become a necessary interface for all devices of digital home, and it is a powerful tool to promote the comprehensive development of digital home industry with 4C integration. The revolutionary DiiVA technology led by Chinese enterprises can not only accelerate the transformation and upgrading of the color TV industry, and further enhance the global competitiveness of Chinese consumer electronics manufacturers; it will also create an interactive application with digital TV as the core for the global industry. The platform will truly bring TV into the 2.0 era, and change from watching TV to using TV; it will drive the formation of a huge industrial chain including chips, complete machines, accessories, various software development and value-added application services; it will also form a high-definition content distribution-based industry chain. The digital home broadband network further promotes the upgrading of interactive applications of digital TV and digital homes around the world.
Achievements: After three years of joint innovation and painstaking research and development, the DiiVA1.0 specification has been formulated. In order to speed up the industrialization process of DiiVA, accelerate the transformation and upgrading of China's consumer electronics industry, and show the revolutionary innovation achievements in the field of digital home to the global electronic information industry. Under the guidance of the Ministry of Industry and Information Technology, and with the support of Guangdong Province, Guangzhou City and China Digital Home Industry Alliance, the China Electronic Video Industry Association will hold a global launch of the DiiVA1.0 specification in Guangzhou, Guangdong Province. TCL, Hisense, Senior executives of Chinese companies such as Skyworth, Konka, Changhong, Haier, SVA, Panda Electronics, and Lingxu will gather in Guangzhou to jointly release the DiiVA1.0 specification to the global industry. At that time, international home appliance and chip giants: Samsung, Sony, Sharp, Panasonic, Toshiba, LG, Japan Avionics, Foxconn, Intel, MediaTek, Sunplus, Realtek, Morningstar, Hollywood content providers and channel distributors will also attend the conference Support DiiVA interface. DiiVA integrates high-definition interface and interactive platform functions, and uses a new concept of digital home network architecture to influence the interactive mode of global TV and digital homes, and promote the comprehensive development of the 4C-integrated digital home industry.
The DiiVA1.0 specification global conference will be held at the location of the "National Digital Home Industry Demonstration Base". At that time, there will be leaders from ministries, provinces and cities, domestic color TV backbone enterprises, well-known foreign home appliance enterprises, and many content providers, chips from Hollywood in the United States, etc. Enterprises and news media that produce and use consumer electronic products such as design, product circulation, network operation and other guests will participate, and the launch event will have a considerable impact on the industry worldwide.
