The Advantages and Disadvantages of DM500C Digital Cable TV STB

The DM500 we are usually talking about is DM500S, the satellite receiver among the DM500 series. Actually, there are three types of DM500. DM500S is the satellite receiver. DM500C is the digital cable TV STB and the DM500T is the ground microwave signal receiver. DM500C is almost same as the DM500S except it can't receive satellite signal. You can do almost everything on DM500C as on DM500S. However, DM500C has many advantages compared to DM500S. 1. DM500C is the best choice for people who own HDTV. In many regions, if you buy the service of digital TV, you will get a free STB using for watching digital cable TV. The STB send to you is often cheap and lack of function. On these STBs, there are always only AV output interface. We know that the AV output could only supports a 450 highest definition. Actually, the definition of digital cable TV often uses the definition of 720*576. So the basic STB cannot restitute the real definition of digital cable TV. DM500 has the Scart output interface, so that it could restitute the biggest definition of digital cable TV. In many digital TV signals, its audio uses the Dolby AC3 or DTS stereo standard. Such audio steam should use the digital optical fiber interface on DM500C to put out or you cannot enjoy the true experience of stereo. 2. DM500C is powerful and cheap. Wen know that if we buy the service for the first time, you can get a free STB, but you won't get another when you order the service again, it will cost you some money to have another STB. If you buy the STB form service provider, you make a wrong decision. DM500C has the same price as a basic STB, but it is a small computer with the open source operating system LINUX. There are much software suits for it. 3. You can record programs onto HDD with computer. As we all know, digital TV signal uses the MPEG 2 DVB-C protocol. If we use the AV output interface to record the programs, we can only record the analog signal. Since DM500C is a network device, we can record the programs to the mounted HDD though LAN. And the definition of the programs will be better. 4. You can watch TV programs on your computer using a DM500C. If we use the VLC or Digital TV Link on PC, we can enjoy the TV programs as well as the TV set.
