2005年8月8日,国家广播电视总局副总工程师、原国家高清晰度电视专家组组长、国家信息化专家咨询委员会委员杜百川在南宁接受媒体采访时称,数字电视并不是指所销售的数字电视机,而是采用数字编码与数字传输技术,进行节目的采集、录制、发射、接收和播出的电视,现有的电视机只要通过机顶盒接收数字信号,就能接收数字电视节目。 On August 8, 2005, Du Baichuan, the deputy chief engineer of the State Administration of Radio, Film and Television, the former head of the national high-definition television expert group and the member of the advisory committee of the national informatization experts, said in an interview with the media in Nanning that digital television does not mean sales Digital television. Instead, digital encoding and digital transmission technologies are used to collect, record, transmit, receive and broadcast television programs. Existing television receivers can receive digital television programs as long as they receive digital signals through the set-top box.
