介绍了NTT电子制造公司的SC2210E标清编码模块。以该模块为基础,设计了便携式演播室级MPEG-2硬件编码器的实现方案以及在开发系统上实现的具体过程,同时简要介绍了该编码器的应用场景。实验表明,设计的编码器结构小巧紧凑,可实现高质量图像的实时编码,延时短。 Introduced NTT electronic manufacturing company SC2210E standard definition coding module. Based on this module, the design scheme of portable studio MPEG-2 hardware encoder and the specific process of developing the system are designed. At the same time, the application scene of this encoder is briefly introduced. Experiments show that the design of the encoder compact structure, enabling high-quality real-time image encoding, short delay.
