摘要

"The process of detection and correction of the failure of one channel to transmit a data stream and apparatus for the detection and correction of errors in a first transmission channel" d .A system for distribution of interactive information in accordance with the present invention a session control manager possessing a defective channel detection module.A module of reorganization of the channel, and a signaling module and replacement.The session control manager is coupled to receive signals from a plurality of converters of the top of the apparatus.And coupled to control the digital video modulators and the names of communication channels to the nodes.The module of the detection of defective channel receive signals of the plurality of converters of top of apparatus,And based on the error rate and other factors, determines whether any of the communication channels used by the digital video modulators are defective.Upon determining that a channel of communication in particular is defective, the defective channel detection module signals to the module of reorganization of the channel.The module of reorganization of channel currents and reorganizes transmitted through the communication channel is defective so that are transmitted through other channels of communication 'Affected and without defect.The replacement signaling module and also identifies the defective modulator of digital video and transmits this information to the network management system which in response follows a procedimeNT pre defined as warning service personnel to replace the defective modulator of digital video.A process for the detection and correction of a defective transmission channel is also part of this invention.
