The Design And Implementation Of The Distributed Hotline Recording System For Digital Director

Hotline is not only the important way for the radio station to give radio broadcast and the audience to participate in the programs, but also the important form of live broadcast. At present, most of the radio station used the traditional phone coupler which is used to realize the hotline access and transfer, as the broadcast station pay more and more attention to the hotline programs, the hotline is more and more important, phone coupler equipment is difficult to meet the business requirements of radio station, so digital director system applications.As digital director system deployment and application in each station, the audience to participate in radio program becomes more and more convenient. Hotline call data statistics provide the useful information for the radio station, these data statistics has very important value for the arrangement of the radio program, therefore the study of hotline recording system is becoming more and more important.The traditional hotline recording system used server to realize voice recording function. so it need high-performance server.The destruction of the Server’s hardware will cause the loss of the whole file resources which is saved for hotline recording. In order to improve these deficiencies, through the analysis and study of the characteristics of the hotline recording, I designed the distributed hotline recording system. I used the modular design method, designed the distributed architecture, the recording system is based on the hardware sound card, the system can reduce the server load and ensure the safety of the recording files. Distributed hotline recording system between the server and the workstations need to transmit a lot of messages, this paper is based on a standard AMQP protocol message middleware system. In addition, to ensure that the distributed hotline recording system can be achieved, it must realize the hotline and hardware sound card connection and call voice interface card. This paper intends to design a distributed hotline recording system by the combination of theory and experiment.
