| 摘 要： | 提出一种对现有数字电视前端设备进行IP化改造的方法。该系统以ARM Cortex-M3内核的LM3S9B92为核心,将TS分组以IP格式封装,利用CY7B933和EP1C3T144C8N芯片,实现了TS流的接收及PCR校正。实测结果表明,该方案中的PCR抖动时延远小于500 ns,节目效果好。

| Abstract: | A DVB front-end equipment IP transformation method is presented.The system is based on the LM3S9B92,and the TS packets are encapsulated in IP format.The receiving of TS stream and the correction of PCR are implemented by using CY7B933 and EPIC3T44C8N.Experimental results show that the design of PCR jitter is far less than 500 ns,and the performance of program is good. |
