在介绍Humax PR-HD1000接收机之前,我们要感谢上海文广新近开播的高清电视节目“新视觉”,让我们第一次接触到DVB-8PSK和DVB-S2。“新视觉”高清节目采用的是DVB-8PSK信道编码方式对外播出,而DVB-S2是一种新工业标准,如同我们的电脑从奔1、奔2一直升级到奔4,它们最大的特点是在现有(信号)信道带宽基础上,可以传送更多的节目,尤其是高清电视节目,从而节省信道带宽资源和传送费用。不过同样也存在兼容性的问题,这也就是我们广大TVRO发烧友使用现有接收机可以接到央视高清节目,却接收不到“新视觉”的原因。
Before introducing the Humax PR-HD1000 receiver, we would like to thank Shanghai Media Group for its newly launched HDTV program, “New Vision,” that will give us first access to DVB-8PSK and DVB-S2. DVB-S2 is a new industry standard for DVB-S2 high-definition programs using DVB-8PSK channel coding, as our PC has been upgraded from Pentium 1 to Pentium 4, and their greatest feature Based on the existing (signal) channel bandwidth, can deliver more programs, especially high definition television programs, thereby saving channel bandwidth resources and transmitting costs. However, there are also compatibility issues, which is why most of our TVRO enthusiasts can receive CCTV HD programs using existing receivers but can not receive “new vision.”
