县级电视台如何把握广电行业数字化、网络化发展的方向,在媒体爆炸的今天能够得以生存,进而取得发展,对自身所处地位的准确定位尤为重要。把视音频矩阵作为过渡期采编网的中转节点,建立类似于星形网络拓扑结构的过渡型采编网,第一可以充分发挥传统模拟采集上传设备的余热,使DVD、VCD、线编等设备通过模拟信号的传输进入采集机,完成数模转换过程;第二可以节约资金,不必每台非编都配备一套编辑机;第三可以形成较为灵活的信号传输链路,一台输出设备可以向任意一台输入设备传输信号;第四可以解决不同非编因编辑格式的不同造成的资源共享障碍。
How the county-level television station grasps the digitized and networked development direction of radio and television industry can survive and explode in the media explosion today, and it is particularly important to accurately locate its own position. The AV matrix is taken as the transit node of the transitional acquisition and editing network to establish a transitional network of acquisition and editing similar to the topology of the star network. The first one can give full play to the residual heat of traditional analog acquisition and upload equipment and make DVD, VCD, Analog signal transmission into the acquisition machine to complete the digital-analog conversion process; the second can save money, do not have to be equipped with a non-editing machine each editing; the third can form a more flexible signal transmission link, an output device can be Any one input device to transmit signals; the fourth can solve different non-compiled editing formats caused by different resource sharing obstacles.
