c++实现的地面数字电视ATSC标准，从加扰到网格编码调制均测试可用。ATSC的英文全称是Advanced Television Systems Committee（美国高级电视业务顾问委员会）。该委员会于1995年9月15日正式通过ATSC数字电视国家标准。ATSC制信源编码采用MPEG-2视频压缩和AC－3音频压缩；信道编码采用VSB调制，提供了两种模式：地面广播模式（8VSB）和高数据率模式（16VSB）。

At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.-sim file system In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements.
