مبدل تیونر به انواع خروجی های استاندارد

ورودی های تیونر پس از رمزگشایی ، تقسیم مجدد ، چند برابر کردن و تغییر شکل ، از طریق رابط های مختلف ویدیویی / صوتی محتوایشان ارائه میگردد. خروجی های ویدیویی و صوتی آن از HDMI ، CVBS ، SDI ، BNC ، رابط XLR و SPDIF پشتیبانی می کند. دارای 2 کارت تیونر ورودی در تمام رنج های DVB S-T-C ، ورودی شبکه و ASI و خروجی یک پورت شبکه UDP و یک الی دو پورت استریو ، پشتیبانی از تلتکست، قابلیت مانیتورینگ و آپدیت وب بیس میسر میباشد. 

roduct Introduction
HD IRD is DEXIN’s new design device. It can receive signals from tuners (DVB-C, DVB-T/T2, DVB-S/S2/S2X, ATSC-T, ISDBT optional). After demodulating, de-scrambling, re-multiplexing and decoding, it gives content out through various video/audio interfaces. Its video/audio outputs support HDMI, CVBS, SDI, BNC, XLR interface and SPDIF.

The two CAMs/CIs accompanied and BISS modules can descramble the programs input from encrypted Tuner, ASI and IP.

Its pluggable structure design greatly facilitates the change of modules (demodulator or decoder) as needed.

To meet customers’ various requirements, NDS3975B/C is also equipped with ASI and IP input for re-mux, and output with 2 ASI ports and IP port..
