机卡分离UTI驱动的开发

The Development of Driver for Set-card Separation UTI

机卡绑定制式限制了中国数字电视产业规模的形成,而机卡分离方案具有性能高、成本低、通用性强等特点,可以从根本上促进数字电视产业的迅速发展。基于高清数字电视系统机卡分离的UTI方案,在μClinux系统下开发了机卡分离UTI的驱动。经过软件调试和硬件联机测试,程序能够驱动UTI卡,实现条件接收、数据广播等功能,具有广阔的应用前景。

Set-card attaching model limits the form of DTV industrial scale. The scheme for set -card separation is characterized by high performance, low cost, wide use etc. , it can make the DTV industry progress rapidly. Based on set - card separation, this paper introduces the development of UTI driver for HDTV under the μClinux system. By software debugging and on- line testing with hardware, UTI card can be driven to complete CA, data broadcasting and other designed functions. It will bring a fine foreground into the embedded application.
