What are the benefits of developing terrestrial digital TV?
First of all, the terrestrial digital TV broadcasting network can transmit radio waves to cover TV users through the antenna at the commanding height of the TV station. Terrestrial broadcasting is also the most basic form of transmission network for digital television broadcasting. In addition to providing public welfare services such as entertainment and learning, its universality, controllability, and invulnerability are also regarded as national security facilities, making it the most direct and reliable government mouthpiece for mobilizing citizens in emergency situations.
Secondly, the development of the terrestrial digital TV market can meet the requirements of people watching multimedia programs anytime and anywhere. The development of digital TV is no longer just how much content to watch, but the flexibility of the viewing location and the randomness of the viewing period.
It is very important that the development of terrestrial digital TV services can make use of a large amount of currently idle wireless spectrum resources to realize more application services to improve frequency efficiency. As a broadcasting operation unit, it can not only use the original TV channels, but also use the idle wireless spectrum to carry out terrestrial digital TV broadcasting, provide mobile reception and portable reception services of digital TV (supporting bit rates greater than 5Mbps), or provide high definition TV in order to use a simple indoor antenna for fixed reception (transmitting a bit rate greater than 20Mbps), to improve the economic benefits of frequency utilization. In addition to developing general digital TV services and data broadcasting, if it can achieve receiver positioning, timing reception and two-way interactive services and personalized information for users, it will greatly expand the service capabilities of wireless channels and provide wireless TV stations Broader development opportunities.
In short, terrestrial digital TV projects have the characteristics of less investment and quick results, and can drive the development of related industries. Launching terrestrial digital TV is tantamount to developing a huge industrial opportunity for China, the world ’s largest TV consumer and producer.
