摘　　要：为使码流发生器播放尽可能多的静止测试卡图像,研究确定了循环播放无闪烁条件下的最小码流长度.试验发现,在包含I、P和B帧图像情况下,最小长度为1MB,在16MBFlashRoom上可存储16幅图像.仅包含I和P帧图像时,最小长度为256kB,可存储64幅图像.新型码流发生器适用于生产线上调试显示器和信源解码设备.In order to store and display as much as possible test pattern of transport stream(TS),the smallest TS length is determined under the situation that the test pattern TS can be circularly displayed without flash. The smallest length is 1 MB including I,P and B pictures, and 16 pictures can be stored in the 16 MB flash room. While if only including I and P pictures,the smallest length is 256 kB, and there are utmost 64 pictures stored in the 16 MB flash room.The new TS generator will be used in product line to check the display and source decoder.
