Информация Компании
We are Sichuan Desai Elctronic Technology Co.Ltd based in chengdu , China. We are member of Tradekey.com since April, 2007. Our business is related to Electrical & Electronics Supplies industry and we specifically deal in CATV products. Please find our product details below: Encoder NDS3201 Encoder Outline NDS3201 Coder is a user-friendly, powerful MPEG-2 Encoder. It supports every standard video and audio signal, including analogue S-VIDEO, analogue composite video, and mono/analogue stereo signal etc. The format of the output of compressed data is ASI/SPI. By compressing input as MPEG-2 MP@ML format，coder real-time encodes and multiplexes audio signal according to MPEG-2 format, and then, generating DVB transport stream. It completely complies MPEG-2 standard, and it has high compatibility. Its dimension is 1U standard case, by watching the LCD display on the front panel, user can finish the setting of auto-running of this machine. Feature Support 4: 2: 0 coding Hi-Fi audio processing R/L channel, stereo input. Output code rate continuously variable, flexible in use. Abundant input/output interface, realizing free connection. Local/Remote net administration possible. LCD display, flexible in operation. High reliability design, stable in running. Specifications Input interface Video signal Level 1.0Vp-p Impedance 75 Ω S-Video Level 0.28Vp-p Impedance 75 Ω Audio signal Level 2Vp-pImpedance 600 Ω Output interface DVB Standard ASI Interface or SPI Interface (Optional) MPEG-2 Video Coding Complying International Standard ISO11172(MPEG-1) and ISO13818 (MPEG-2) MPEG-2 coding as 4：2：0MP@ML Output code rate 1.0~15Mbps continuously variable MPEG-2 automatically fit frame (AFF) MPEG-2 frame base (FB) Format: DVB standard transport stream (TS) Audio Coding Audio adopting MPEG-1 2nd layer,CD audio quality Audio sampling rate: 32KHz、44.1KHz、48KHz Audio code rate: 64、128、192、256、384Kbps Support single channel stereo / double channel mono Resolution Complying CCIR601Standarad Support 1/2D1，2/3D1，3/4D1，FullD1 PAL：720´576，704´576，640´576，544´576，480´576，384´576，352´576 NTSC：720´480，704´480，640´480，544´480，480´480，384´480，352´480 Multiplexer Product Description NDS3101 multiplexer is a digital broadcasting TV system TS stream re-multiplexer. NDS3101 multiplexer combines several single-programs or multiple-programs, which are compressed, coded, and multiplexed according to customer request by head-end, into single transport stream. Besides, it is also able to interpolate EPG (Electronic Program Guide), CA (Conditional Access) and digital broadcasting etc. Maximally, it can synchronal multiplex 8 route input code streams, and support ASI interface. The code rate of input code stream is maximally up to 270Mbps, while code rate of output code stream is maximally up to 108Mbps. Through auxiliary data input channel, it can real-time interpolate the data, created by outer SI(Service Information)server, into output code stream, in order to realize the EPG and digital broadcasting etc. Value added business. Its dimension is standard 1U case. By watching the LCD display on the front panel, user can finish the setting of auto-running of this device Features Complying ISO13818 standard. Support MPEG-2 transport stream re-multiplexing. Multiplexing SPTS and MPTS code stream. SDT table reflection Able to connect independent scrambler for scrambling to specified program or service. Generating SPI/SI information Support PCR adjusting and PID re-reflection Able to extract PSI/SI information from any route of SPTS/MTPS inputs Able to interpolate data, and re-multiplex and transport any kind of data Support statistic multiplex Support the cascading connection of several equipments. Central net administration, remote updating and maintenance LCD display, flexible and user-friendly in operation High reliability design, stable in running Alarm display Support network upgrade. QPSK Modulator Product Description Outline QPSK digital TV modulator adopts advanced digital signal processing technology, of which receiving port can directly use digital satellite receiver for receiving, thus fully complying DVB-S standard. Not only can it gain relatively high frequency spectrum usage ratio, having very strong anti-interference and relatively high price performance ratio, but also it can well comply analogue FM microwave equipment. QPSK digital TV modulator adopts various processing method, such as random energy spread processing, RS coding, convolution interweave, contracting convolution coding, and pre-modulating baseband shaping processing, etc. All these contribute a high guarantee to the data transmitting performance. Feature Complying DVB-SETS300-421 QPSK modulating standard If output frequency range 950MHz~2150MHz (it can be set as users' needs) Build-in frequency synthesizer, support uplink frequency conversion in U band 450~950MHZor L band 950~2150MHz Ports complying ASI, SPI standard QAM Modulator Product Description Outline NDS3303 QAM Modulator, is the main equipment CATV digital head-end, receiving DVB transport streams which come from coder, multiplexer, DVB gateway, scrambler, video server etc. It does signal processing like RS coding, convolution interleaving and QAM modulating, providing IF/RF output. Feature Complying DVB standard signal channel coding. Support full range variable data rate, bandwidth and QAM mode Data stuffing PID filter, re-reflection, PSI, SI information synchronal updating possible. Automatically code stream stuffing and empty pocket deleting. Code stream real-time monitoring, empty pocket filtering Support NIT table modifying PCR adjusting, output symbol rate variable: 1-7M/s Fixed or agile channel output; Providing ASI and DS3 code stream interface. Providing RF output monitoring port(-20dB) Local or Remote administration possible. LCD display, flexible in operating High reliability design, stable in running Thank you for taking the time to go through our business profile.
