【摘要】： 广播全台网络是电台数字化的基础,因此在电台计算机综合信息系统中占据着相当重要的地位。未来广播电台将同时面对采编系统、文稿系统、播出系统、广告资源系统、媒体资产管理系统、网上广播/点播系统等多种平台,各平台之间将实现对接、整合与兼容,而现有系统在一体化全方位解决上大多没有考虑。随着技术进步和电台需求的变化,广播全台网络的原有节目录编模式与技术架构也逐渐需要改变,在系统的高效性、安全性,稳定性,音频文件格式转换和音量自动均衡等问题上都需要有新一代的系统与之适应。本课题运用多媒体技术、数据库技术、软件工程技术、软件应用系统等多种开发技术,结合优秀的Audition音频录制、编辑平台,研究了广播全台网络的节目录编子系统。它为广播电台网络的其他子系统提供了直接可用的素材,实现了广播电台节目制作和高速入库的数字化,同时为广播电台实现自动播出做好了充分的准备,是数字广播电台服务平台的重要支撑。本文围绕着满足广播电台网络对节目录编高效、实用、稳定、安全等要求,完成了如下内容: 1、详细叙述了批量转码导入功能模块的设计与实现,为新建数据库填充内容提供了高效、快捷的方法; 2、详细叙述了音量自动均能功能模块的设计,实现了在入库过程中计算、保存音频文件的音量均衡信息,以在播出时实现音量自动均衡功能; 3、通过改造优秀的音频录制和编辑软件Adobe Audition软件,使其支持S48音频格式以及与数据库的结合,实现了Audition与节目录编系统的完美集成,为播出系统提供品质更高的素材; 4、本文最后,对各个模块进行了相应功能验证。
[Abstract]:The broadcast network is the foundation of the radio digitization, so it occupies a very important position in the radio computer integrated information system. The future broadcasting station will face many platforms, such as the editing system, the manuscript system, the broadcasting system, the advertisement resource system, the media asset management system, the network broadcasting / on-demand system and so on. To achieve docking, integration and compatibility, most of the existing systems are not considered in an integrated and omni-directional solution. With the development of technology and the change of radio demand, the original program recording and technical architecture of the broadcast network is also gradually changed, in system efficiency, security, stability, audio file format conversion and volume automation. Equilibrium and other issues require a new generation of systems to adapt to it.
This topic uses multimedia technology, database technology, software engineering technology, software application system and many other development technologies, combined with excellent Audition audio recording and editing platform, and studies the node cataloging system of broadcast network. It provides direct available material for other subsystems of radio network and realizes broadcasting electricity. It is an important support for the service platform of the digital radio station, which is fully prepared for the broadcasting station to realize automatic broadcasting.
This article focuses on satisfying the requirements of radio network's efficient, practical, stable and secure programs.
1, the design and implementation of batch transcoding module is described in detail, which provides an efficient and fast way to fill content in new database.
2, the design of the volume automatic function module is described in detail, and the volume balance information of the audio files is saved in the process of entering the library, so as to realize the automatic volume balance function when broadcasting.
3, through the transformation of excellent audio recording and editing software Adobe Audition software, it supports the S48 audio format and the combination with the database, realizes the perfect integration of Audition and program recording system, and provides higher quality material for the broadcast system.
4, in the end, the corresponding functional verification of each module is carried out.
