Outline

NDS3915 DVB-S2 HD IRD with CI slot can decode transport stream from ASI, tuner or IP sources into audio & video signal. With the help of CAM module, it can decrypt the encrypted programs in the input TS. Apart from this function, it also can encapsulate the output TS into IP pocket and output in UDP protocol. User can watch the contents of the IP outputs from decoding software on computer. The professional IRD has full-range of output interface ports, such as HD-SDI, SD-SDI, HDMI, YPbPr, XLR, S/P DIF, etc., which can satisfy the professional user’s needs.
