【摘要】： 廣播全臺網(wǎng)絡是電臺數(shù)字化的基礎,因此在電臺計算機綜合信息系統(tǒng)中占據(jù)著相當重要的地位。未來廣播電臺將同時面對采編系統(tǒng)、文稿系統(tǒng)、播出系統(tǒng)、廣告資源系統(tǒng)、媒體資產(chǎn)管理系統(tǒng)、網(wǎng)上廣播/點播系統(tǒng)等多種平臺,各平臺之間將實現(xiàn)對接、整合與兼容,而現(xiàn)有系統(tǒng)在一體化全方位解決上大多沒有考慮。隨著技術進步和電臺需求的變化,廣播全臺網(wǎng)絡的原有節(jié)目錄編模式與技術架構也逐漸需要改變,在系統(tǒng)的高效性、安全性,穩(wěn)定性,音頻文件格式轉換和音量自動均衡等問題上都需要有新一代的系統(tǒng)與之適應。 本課題運用多媒體技術、數(shù)據(jù)庫技術、軟件工程技術、軟件應用系統(tǒng)等多種開發(fā)技術,結合優(yōu)秀的Audition音頻錄制、編輯平臺,研究了廣播全臺網(wǎng)絡的節(jié)目錄編子系統(tǒng)。它為廣播電臺網(wǎng)絡的其他子系統(tǒng)提供了直接可用的素材,實現(xiàn)了廣播電臺節(jié)目制作和高速入庫的數(shù)字化,同時為廣播電臺實現(xiàn)自動播出做好了充分的準備,是數(shù)字廣播電臺服務平臺的重要支撐。 本文圍繞著滿足廣播電臺網(wǎng)絡對節(jié)目錄編高效、實用、穩(wěn)定、安全等要求,完成了如下內(nèi)容: 1、詳細敘述了批量轉碼導入功能模塊的設計與實現(xiàn),為新建數(shù)據(jù)庫填充內(nèi)容提供了高效、快捷的方法; 2、詳細敘述了音量自動均能功能模塊的設計,實現(xiàn)了在入庫過程中計算、保存音頻文件的音量均衡信息,以在播出時實現(xiàn)音量自動均衡功能; 3、通過改造優(yōu)秀的音頻錄制和編輯軟件Adobe Audition軟件,使其支持S48音頻格式以及與數(shù)據(jù)庫的結合,實現(xiàn)了Audition與節(jié)目錄編系統(tǒng)的完美集成,為播出系統(tǒng)提供品質(zhì)更高的素材; 4、本文最后,對各個模塊進行了相應功能驗證。
[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.
