Triple play will bring five benefits to urban residents: 1. Information service will shift from single service to multimedia integrated services such as text, voice, data, image and video. 2. It is conducive to greatly reducing infrastructure investment, simplifying network management and reducing maintenance costs. 3. The network will change from an independent professional network to an integrated network, the network performance will be improved, and the level of resource utilization will be further improved. 4. Triple play is the integration of services, which not only inherits the original voice, data and video services, but also derives more abundant value-added service types through network integration, such as teletext, VoIP, video mail and online games, which greatly expands the scope of service provision. 5. Triple play has broken the long-term vicious competition between telecom operators and broadcasting operators in the field of video transmission. Major operators will scramble for food, and the tariffs for watching TV, surfing the Internet and making phone calls may be reduced.
