DM500S PC Receiver Decoder 

Description:

In brief, DM500S receiver decoder is a linux system computer. you can watch 7 different satellite packages, such as:68.5 degree of South Africa satellite, 76.5 degree of Taiwan satellite,78.5 degree of Thai satellite,88 degree of Taiwan satellite,122 degree of HK satellite, 138 degree of Taiwan satellite, 146 degree of Philippines satellite at same time by installing all of software in one DM500S decoder.

Why to choose DM500S:

• Exquisite design and smaller size(W*D*S) :195mm*130mm*40mm,weight: 0.6kg.
• Powerful function such as to share different satellite packages by one software. So, you no need to switch when you change between different satellite programs.
• You can watch coded program by inserting smart card or inserting PC1020 card to share Internet program.
• Flexible watching by Internet or TV set.
• Exquisite picture and soft sound quality.
• You can book recording.
• Different language menu.
• English manual
• Had been used widely in oversea.
• More software of this model will been developing in future.
