Digital home network system and transmission method thereof

Abstract

The invention discloses a digital home network system and a transmission method thereof. The core concept is as follows: when all types of terminals inside a home are subjected to networking, a wired home communication network and a short distance wireless communication network are used simultaneously, i.e., a wired transmission channel and a wireless transmission channel are provided simultaneously; and when specific business data is transmitted, a home network controller is used for selecting and controlling an actually-used hosted network. According to terminal types and / or the characteristics of applied business, resource conditions of current wired / wireless networks and the like, the hosted network is selected and configured reasonably, the problem of performance restriction in a single transmission path is solved, and idle network resources are utilized maximally.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a digital home network system and a transmission method. Background technique [0002] Home networking technology can turn a home into a smart home with various convenient applications. The basic solution is to connect various information appliances with high communication capabilities through the home network, that is, they can communicate with each other and with the outside world. Every home appliance connected to the home network becomes a network terminal. . [0003] The internal networking scheme of the existing home network mainly includes the following three situations: [0004] 1. Use wired transmission technology for home network networking. The wired home communication network used mainly includes telephone lines, Category 5 lines, cable TV cables, power lines, etc. Take the networking scheme based on power line communication as an example, such as figure 1 A...

AI Technical Summary

Problems solved by technology

Take the networking scheme based on power line communication as an example, such as figure 1 As shown, the circuit inside the home is isolated from the external power grid through the wave trap to carry the communication signal. Various terminals are connected through the power line and connected to the external network through the home gateway. The disadvantages of this solution are: First, no matter what kind of wired technology is used, the coverage inside the home network must be limited by the number and location of the corresponding plugs in the home, especially coaxial cables and category 5 sockets , the number is very small, usually only 2-3 per family, and for many home network terminals, such as PDA, etc., it is usually not necessary or desirable to have a wired connection; the second is that the data transmission capacity is limited and cannot be effectively supported. Various high-speed service requirements for future home networks, such as simultaneous transmission of multiple high-definition multimedia services

The disadvantages of this solution are: First, it is difficult to meet the coverage requirements inside the home network. Generally, the communication distance of short-distance wireless transmission technology is very limited, usually within 3-10 meters, and many houses are built of stone and concrete. , the communication capability will drop sharply due to the fading of the internal walls of the home, or even completely unable to communicate; second, the data transmission capability is very limited, and the peak rate generally does not exceed 54Mbps, which is far from meeting the business needs of future home networks

The disadvantage of this solution is that it does not improve the limited coverage and the limited data transmission capacity in wired transmission or short-distance wireless transmission. The two schemes are the same, and no essential changes and improvements have been achieved
