IPTV即交互式网络电视,是一种利用宽带有线电视网,集互联网、多媒体、通讯等多种技术于一体,向家庭用户提供包括数字电视在内的多种交互式服务的崭新技术。IPTV既不同于传统的有线电视,也不同于目前正在兴起的数字电视。通过IPTV业务,用户可以得到高质量(接近DVD水平的)数字媒体服务,可以自由选择宽带IP网的视频节目,实现媒体提供者和媒体消费者的实质性互动。IPTV的出现在宽带视频应用方面填补了空白,支起了宽带市场的另一片蓝天。它将电视、通信和计算机三个领域结合在一起,被业界喻为撬开宽带市场的新支点。
IPTV is an interactive Internet TV. It is a brand-new technology that uses broadband cable television network, Internet, multimedia and communications technologies to provide home users with a variety of interactive services including digital television. IPTV is different from the traditional cable TV, is also different from the current rise of digital television. Through the IPTV service, users can get high-quality (near-DVD level) digital media services and have the freedom to choose broadband IP network video programs to achieve substantive interaction between media providers and media consumers. The advent of IPTV fills the void in broadband video applications, supporting another piece of blue sky in the broadband market. It combines the three fields of television, communications and computer and is praised by the industry as the new fulcrum to unlock the broadband market.
