随着图形、图像数字化技术向深层发展,电子采集、后期编辑、节目播出设备将以网络方式互联,实行节目数据的交互式作业方式。作为体现新技术特征的基于硬盘的播出系统,由于它良好的非线性编辑性能、多通道的编解码器、长时间的节目存储量、周详的安全考虑和灵活的网络功能,在电视播出领域的应用已成为电视技术人员关注的焦点,可以肯定预测基于硬盘的播出方式会逐步替代传统的磁带播出概念,成为电视节目播出的最佳方式。实现电视节目的自动播出,是电视台数字化改造最必须、也是最重要的一步。
With the development of graphics and image digitization technology, the electronic collection, post-editing and broadcast equipment will be networked and networked, and the interactive operation of program data will be implemented. As a hard-disk-based playout system that embodies the new technology features, due to its excellent non-linear editing performance, multi-channel codecs, long program storage, careful security considerations and flexible networking capabilities, Applications in the field have become the focus of television technicians and it is certain that the hard disk-based broadcasting method will gradually replace the traditional concept of tape broadcasting and become the best way to broadcast television programs. Realizing the automatic broadcast of television programs is the most necessary and most important step for digitizing TV stations.
