随着计算机技术的发展,磁盘记录设备的不断完善,其稳定性越来越高,容量越来越大。这就使磁盘成为非线性记录媒体有了坚实的基础。目前,将磁盘作为记录媒体的非线性产品,以非常惊人的速度进入了广播电视领域。这些产品与线性产品相比,除了体积小,重量轻,可靠性高等特点外,它的最显著的优点是能对素材进行非常灵活、方便、快捷的各种操作。目前,我国的广播电视主要是以线性媒体播出为模式,因此,无论是从经济角度,还是从电视播出的管理模式,人员的技术适应等方面考虑,非线性播出完全取代线性播出将有很长一个过程。针对这个情况,我们把研发的重点放在非线性和线性的混合播出上,并应用到实际播
With the development of computer technology, the continuous improvement of the disk recording equipment has made it more and more stable and has an increasingly large capacity. This makes the disk a non-linear recording medium has a solid foundation. At present, the non-linear products that use a magnetic disk as a recording medium enter the field of radio and television at an alarming rate. In addition to their small size, light weight and high reliability, these products have the most remarkable advantages over linear products in that they can perform very flexible, convenient and quick operations on materials. At present, China’s radio and television are mainly broadcast as a linear media model, therefore, whether from the economic point of view, or from the television broadcast management mode, personnel and other aspects of technology to adapt to consideration, non-linear broadcast replaces the linear broadcast There will be a long process. In response to this situation, we focus on research and development of mixed nonlinear broadcast and linear broadcast, and applied to the actual broadcast
