This year is the last year of the three-network integration pilot, and Dianguang Media timely launched a fixed increase plan for "building the next generation of broadcast and television networks and achieving full-service operation upgrades." Industry insiders believe that this is a key step for Dianguang Media to actively prepare for the integration of the three networks.
Minsheng Securities analyst Zheng Ping believes: "This move is in line with the development direction of the cable TV industry NGB and the company's strategic thinking to make the cable TV industry bigger and stronger, which can enhance the company's effectiveness in responding to the 'three network integration' competition methods and enhance the company's media main business. Of sustainable growth. "
What is NGB?
"NGB is actually a high-speed network ecosystem with video communication as the core and converging to support various communication services. Network operators, business content operators, access operators and other operators operate in network operations, business operations, and terminals. Operation, channel operation, operation control and other aspects are organically integrated on NGB to form an ecosystem with the network as the core and symbiosis. "Zeng Jiezhong explained the basic functions of NGB with an image metaphor.
In 2006, the 11th Five-Year Plan proposed to actively promote the integration of the three networks and build a digital TV network integrating cable, terrestrial and satellite transmission. The prophetic and prescient TV broadcast media had already predicted this blue ocean.
"When the overall platform of digital TV was transformed in 2007, we laid the hardware foundation for the subsequent integration of the three networks." Zeng Jiezhong told reporters.
It is understood that Dianguang Media had laid the groundwork for the integration of the three networks in set-top boxes and access technology as early as the transformation of the overall digital TV platform. "At that time, when the national digital TV one-way set-top box was distributed as a whole, Hunan analyzed and predicted the future business development and made a decisive decision. All the two-way set-top boxes were released. Enjoy the symmetrical access network transformation technology route. "Zeng Jiezhong whispered.
The so-called symmetrical exclusive bandwidth means that the user's downlink data transmission capability obtained from the metropolitan area network and the user's uplink data transmission capability to the metropolitan area network are consistent. Zeng Jiezhong introduced: "The network reform access technology adopted by Hunan makes full use of the high and low frequency band resources of the coaxial cable for digital processing, replaces the five types of wires with the coaxial cable, and adopts the industry's most mature IP network switching technology without re-laying In the case of cables, on the basis of the existing coaxial cables, individual users can enjoy exclusive access to upstream and downstream symmetric 30-100Mbps access communication capabilities. "
Zeng Jiezhong cited a simple example. For example, due to the limitation of the upload speed of the current video chat, the chat screen is neither clear nor smooth, and the above technical route can solve this problem.
"Now users have access to coaxial cables in their homes, and we do n’t need to re-connect the wires when carrying out the NGB transformation. We can completely avoid digging holes, penetrate walls, and disturb people. This not only protects the original investment, but also reduces After the NGB construction is completed, no major changes are necessary for 5 to 10 years. "Zeng Jiezhong told reporters.
What is running on NGB?
According to Zeng Jiezhong, NGB will be an intelligent network. First of all, the current basic business of digital TV, including live TV, VOD on demand, 3D, this will be the basic business of NGB. Secondly, NGB's future development areas are mainly concentrated in the three major sectors of green Internet, video communications and cloud TV.
"Green Internet mainly solves the problem of unhealthy content on the Internet. Our content is green and can be controlled; video communication can be applied in many fields such as family communication, medical consultation, peer-to-peer education, business office, etc .; cloud TV It is an integrated business platform. "Zeng Jiezhong summarized.
In Zeng Jiezhong's office, he demonstrated a video communication for reporters on the spot, and the required equipment was just an ordinary TV set, a TV set-top box developed by Hunan Cable Network Group about 20CM long, about 5CM high, and a camera.
The staff dialed a video call to his office through the television in the office next to Zeng Jiezhong. After pressing the OK button on the TV remote control, the other party ’s image was transmitted through the TV screen, and our image was also It is displayed in the upper right corner of the TV. The two images can be switched freely between large and small screens, and unlike network video communication, its image is very clear, and the conversation between the two parties is also very smooth, there is no phenomenon of audio and video delay.
"Now this technology has reached the point where you don't need a receiver or a microphone to talk directly to the TV within 5 meters. Compared to the small window video communication on the Internet, this technology prospect of direct 720P resolution HD video communication directly through the TV It's very broad. "Zeng Jiezhong was proud when he introduced this technology.
"Family communication between children and parents can shorten the distance between each other; young parents can monitor children in kindergarten in real time through video communication; video treatment for the elderly with impaired mobility, can complete preliminary disease diagnosis, etc. How much can this pull Industry, how many jobs can be solved, how many difficulties can be eliminated for the people. "Zeng Jiezhong explained in detail.
