The Small Radio Broadcasts Automatically Broadcast System Broadcast Stations Design And Implementation

The broadcast automation which is based on the technologies of digital audio, computer network and multimedia has changed the traditional way of program production, management and broadcasting mode of the radio. It also facilitates the digitalization and automation process of radios' program production and broadcasting. An automatic broadcast system characterized by rich functionality and being easy to use can greatly increase the working efficiency of the radio and relief the manual workload as well as improve the program quality. With the development of multimedia technology and the increasing demand of the mass media, there is a trend for the radio to establish an automation network system.Nowadays, automated broadcast systems which are specifically developed for small radios are lack in practice. Such systems have the following features: Using the cheap or free database to reduce the cost, which makes the systems more cost-effective; Cutting the unnecessary access restrictions according to the scale, which improves the use flexibility; Removing the functionalities that are infrequently used which shortens the development period and reduces the sale price.The task of this project is to develop broadcasting software for automated broadcast system which is suitable for small radios by using the tool of Delphi and Access database. The thesis describes the principle and method in detail, which are used in designing the software from all aspects including the designs of functionality, interface and database, and the selections of audio interface and sound card, as well as the designs of main data structure and modules, etc. In the last part of the paper, the evaluation and running interface are also presented.
