System, method and device for providing the bidirectional service in the separated bidirectional network

Abstract

This invention discloses a separate two-way network providing two-way business methods, the method includes the following steps: two-way network switching equipment to receive at least two-way business information, docking of two-way business information received conversion processing, then send the converted two-way transmission information. This invention disclosed the systems and equipment providing two-way business in separate two-way networks, using of two-way network switching equipment to receive all kinds of information t of two-way business, and converse the different received information of two-way business separately. Two-way business reception processing equipment can receive and processing the information content of two-way business and deal with different business separately.

Description

System, method and device for providing bidirectional services in a split bidirectional network technical field The invention relates to network two-way service technology, in particular to a system, method and equipment for providing two-way service in a separated two-way network. Background technique With the increasing popularity and promotion of digital TV services, a large number of two-way services have emerged, including: video on demand (VOD), interactive TV and interactive games. Hybrid Fiber Coaxial Cable (HFC) network is a multifunctional optical-electrical broadband integrated network with a star structure. The network has a large-bandwidth downlink broadcast channel and rich frequency resources, and divides signals according to frequency division multiple access. , so multiple unrelated signals can be transmitted at the same time; Internet Protocol (IP) network bandwidth is relatively low, and Quality of Service (QoS) is not guaranteed. Therefore, in a digita...

Problems solved by technology

It can be seen that, in the prior art, there is no unified system, method and equipment to handle various bidirectional services, resulting in problems such as complex system structure, high networking cost, and heavy development workload.
