Remote disaster tolerance system and method for interactive television

Abstract

The invention discloses a remote disaster tolerance system and a remote disaster tolerance method for an interactive television. The method comprises the following steps that a set-top box initiates a service data request message to a city gateway; the city gateway transmits a request to a city background management system; the city background management system notifies a city video server to transmit a stream; the city video server acquires service data from a city content caching system, and transmits the stream to the set-top box to satisfy the request of the set-top box; and the set-top box initiates a service data request message to a disaster backup gateway in case of an access failure during the request, and a disaster backup center provides service for the set-top box. When the service is failed to be locally provided for a user, the set-top box can be automatically switched to provide the service for the user by the disaster backup center to realize accurate user-level disaster backup, so that a certain module in the whole system is seamlessly switched with the other modules when failing, the crash of the whole system caused by the failure of a single point is avoided, and the stability and the reliability of the system are improved.

Description

technical field [0001] The invention relates to a disaster recovery system for interactive TV, in particular to a remote disaster recovery system and method for interactive TV based on portal address redirection. Background technique [0002] At present, the application services of the radio and television network used by users in various prefecture-level cities are provided by the local operator where the user is located. When a middleware of the local radio and television network system fails, all Users will not be able to request the corresponding service data; at the same time, because there is no unified interactive TV technical standard in most of the interactive platforms deployed in various cities in China, all kinds of interactive video systems deployed by operators are provided by operators. Self-customized, composed of components with high coupling, so that the existing disaster recovery plan is only established within the local scope of each city, resulting in th...

[0002] At present, the application services of the radio and television network used by users in various prefecture-level cities are provided by the local operator where the user is located. When a middleware of the local radio and television network system fails, all Users will not be able to request the corresponding service data; at the same time, because there is no unified interactive TV technical standard in most of the interactive platforms deployed in various cities in China, all kinds of interactive video systems deployed by operators are provided by operators. Self-customized, composed of components with high coupling, so that the existing disaster recovery plan is only established within the local scope of each city, resulting in the lack of a complete disaster recovery plan, once a local middleware appears The problem is that the entire system is immediately paralyzed and cannot respond to user requests, resulting in a large amount of repeated investment in construction and increased system maintenance costs, and the stability of the system is poor, and users cannot receive high-quality services
