实现了以ST公司的专用芯片组为核心器件的HDTV码流发生器内置信源解码板的设计.在内置的信源解码板的配合下,以万禾嵌入式Linux系统开发板为核心的码流发生器不仅可以输出符合MPEG II国际标准的传送流,还可以直接输出解码后的HDTV模拟音视频信号,供HDTV显示器直接显示.该仪器可在数字HDTV研究及HDTV生产、销售和展示中发挥重要作用.
And realized the design of the built-in source decoding board of the HDTV stream generator taking ST’s dedicated chipset as the core device.In cooperation with the built-in source decoding board, the code centered on the Wanhe Embedded Linux System Development Board The stream generator not only outputs MPEG-II compliant transport streams, but also directly outputs decoded HDTV analog audio and video signals for direct display on HDTV displays that can be used in digital HDTV research and HDTV production, sales and display Important role.
