摘要
电视广播控制系统伴随千兆、40GB等局域网的搭建及高清摄像机的普及,向4K超高清广播方向发展。因4K具有较高的比特率,基带信号难以应用于广播系统的广播。为此,针对基于IP流信号的4K广播系统实际应用及应用中存在的问题进行了深入分析及研究。
With the construction of Gigabit,40Gb LAN and the popularity of HD cameras,TV broadcast control system is developing towards 4K Ultra HD broadcasting.Because 4K has a high bit rate,baseband signal is difficult to be used in broadcasting system.In this paper,the practical application of 4K broadcast system based on IP stream signal and the existing problems are deeply analyzed and studied.
