IPTV is an Internet-based service, so its terminals are diverse and highly intelligent. There are not only set-top boxes based on SOC architecture, smart terminals based on smart chips, and set-top boxes similar to personal computers based on X86 architecture. At the same time, the IPTV service is an intelligent and highly interactive service with diverse types and complex logic. Due to its use of Internet technology, it has high requirements for privacy and security. The complexity of IPTV terminals and services makes effective management of IPTV terminals a necessary condition to ensure the quality of IPTV services, but it also places high requirements on terminal management. Therefore, IPTV terminal management has been an important research in the industry from the beginning. Subject.
2. The structure and research content of IPTV terminal management
2.1 IPTV terminal management structure
The main function of IPTV terminal management is to complete the unified management of IPTV terminals, realize terminal network configuration, status and performance monitoring, system and business configuration, software version and upgrade management, fault diagnosis and other functions. IPTV terminal, network interface, and management server are the three essential elements that make up IPTV terminal management. The basic implementation of IPTV terminal management is that the management server invokes the corresponding functions on the terminal through the network interface protocol to realize the specific functions of terminal management.
2.2 IPTV terminal management research content
In the continuous research and development and practice of IPTV terminal management, its key technologies mainly involve the following aspects.
(1) Northbound interface
This interface exists between the IPTV terminal management system and other functional entities on the IPTV platform side. Since the IPTV terminal is a part of the IPTV network, IPTV terminal management has the dual characteristics of network management and service management. The northbound interface includes two interfaces of the IPTV terminal management system, network management system, and service management system. Among them, network management is responsible for network configuration information transmission, fault diagnosis, failure warning and other functions, and business management is responsible for statistical information transmission, business management and configuration.
(2) Southbound interface
This interface exists between the IPTV terminal and the management system, and it is also the most important, frequently used, and fully demonstrated technology in terminal management. This interface directly carries various function calls such as terminal management status monitoring, parameter settings, abnormal alarms, log upload, software upgrades, and fault diagnosis. In the actual application of IPTV, the interface protocol has two forms: SNMP[1] and TR069[2].
(3) Home Gateway
At present, the application of home gateways is extremely common, and the collaborative work of IPTV services and home gateways is also a hot topic of discussion in the industry. From the perspective of terminal management, the most critical technical issues are NAT (network address translator) traversal and binding access authentication. In the NAT environment, the IPTV terminal generally traverses the home gateway through mechanisms such as timing heartbeat [3], and solves the problem of access authentication in routing mode through DHCP (dynamic host configuraTIon protocol) extension and management protocol authentication [3, 4] .
(4) Configuration and upgrade
The segmentation of the software system business function modules in the IPTV terminal is closely related to the software upgrade, system and business configuration of the terminal management. Under the requirements of a complete IPTV terminal management function, the IPTV terminal needs to have software modules designed for different functions and different services of the system, and at the same time, it can download and configure the service functions by itself according to the management requirements.

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:
I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).
I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).
I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).
Below are the approximate range of different power FM Transmitters. ( The range is diameter )
0.1W ~ 5W FM Transmitter ：100M ~1KM
5W ~15W FM Ttransmitter : 1KM ~ 3KM
15W ~ 80W FM Transmitter : 3KM ~10KM
80W ~500W FM Transmitter : 10KM ~30KM
500W ~1000W FM Transmitter : 30KM ~ 50KM
1KW ~ 2KW FM Transmitter : 50KM ~100KM
2KW ~5KW FM Transmitter : 100KM ~150KM
5KW ~10KW FM Transmitter : 150KM ~200KM
