利用音频基带变频技术实现跨网络文件传输

Cross-network File Transfer Based on Audio Frequency Conversion Technology

AES/EBU现已成为电台数字化的专业数字音频标准,传统媒体和新媒体的融合发展又带来更多的互联网和制播业务网数据传递的要求,安全可靠的网络间音频文件的传输是电台数字化、网络化后面临的重要课题。本文提出了在保障制播系统安全前提下利用现有的标准体系结构,采用新的应用方式实现跨网络文件传输方式。该技术在保障安全的前提下安全高效的将音频文件由外部网络传输到电台的制播网络系统中,支持了电台节目制播业务生产的时效性、多样性。

AES/EBU has become digital radio in the professional digital audio standard, and integration and development of the traditional media and new media bring more Interuet and broadcast business network data transmission requirements. Safe and reliable network audio file transmission is digitization and networking of radio after facing an important issue. Under the premise of the broadcasting system of guarantee safety using the existing standard system structure, the new application way to achieve cross network file transfer mode is proposed in this paper. Under the premise of security, the technology of the audio files transmits to the external network radio broadcasting network system to support the timeliness of radio broad- cast business production and diversity.
