Problems solved by technology
[0007] It can be seen from the above types of technologies that the wired transformation method cannot avoid the home installation process, even the EPON+EoC, which is more convenient to install, cannot be avoided. This will cause a lot of construction costs, and the cost of two-way transformation will also increase accordingly With the improvement, it will be more difficult for radio and television to make profits. In addition, due to the many wiring problems encountered in how to construct, it will also affect the determination of users to carry out two-way transformation, which will greatly affect the promotion degree and market penetration rate of two-way transformation

Embodiment Construction
[0022] The embodiment of the present invention has strong adaptability and flexible networking, supports both star networking mode and distributed mesh network topology mode, and the wireless module itself is low in cost. In addition, this method saves tedious and high-cost wired wiring The construction method is therefore extremely convenient and the cost is very low.
[0023] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.
[0024] Such as figure 1 As shown, the broadcast and television digital backhaul method of the embodiment of the present invention includes:
[0025] Step 1: The set-top box generates a return signal according to the received downlink service;
[0026] Step 2: The set-top box transmits to the wireless module through the external interface;
[0027] Step 3: The wireless module transmits the signal of the set-top box to another wireless module connected to the fron...

The invention relates to a digital return technology which is one of radio and television two-way transformation technologies. The embodiment of the invention comprises the following steps of: producing a return signal by a set-top box according to a received downlink service, transmitting the return signal to a wireless module by the set-top box through an external interface, transmitting the signal of the set-top box to another wireless module connected with a front-end server by the wireless module, and receiving the wireless signal and then transferring to the front-end server by the wireless module. The platform is strong in applicability and flexible in networking, and can support not only a star type networking way, but also a distributed mesh network topology way; furthermore, the wireless module is low in cost; and in addition, according to the method, the cockamamie high-cost wire type wiring construction way is eliminated, the transformation is very convenient, the cost is very low, and the two-way transformation requirements of a radio and television system can be fully met.
Description
Technical field [0001] The invention relates to the field of broadcast and television, in particular to a low-cost and convenient construction method and system device for broadcast and television digital backhaul. Background technique [0002] Currently, the radio and television field is actively discussing the issue of digital two-way transformation. The traditional cable television network is one-way transmission, which is a downlink broadcast transmission. The current cable TV network hopes to add backhaul equipment to achieve two-way asynchronous transmission. Therefore, the so-called two-way transformation is to change the original one-way device to two-way device. At present, most of the solutions are all wired transformation methods, that is, the cable is changed to optical cable, and the electrical signal building amplifier is changed to optical receiver. The high-end transformation also includes the entry line from the double shielded line to the four shielded coaxial ...
