DVB-C Set Top Box

Overview Our DVB-C HD STB is designed accordingly to DVB-C International Standard and technical standard by China Broadcasting Association. 3C, ISO and Energy Efficiency certification is approved. DVB-C standard, support digital video and audio broadcasting and subtitle ment and other functions, such as digital video, audio broadcasting, EPG, boot screen, subtitle picture advertising, etc.  Montage M88cc6000-t010 main chip design.CAS is intergrated(E.g :DIGICAST CAS). The main chip USES a high-performance dual MIPS CPU with 1Gb DDR and 8MB Flash capacity. Support left, right, stereo, mixed output, with channel remote switch function, default output is left channel. The loader of the set-top box can meet relevant standards and run stably. The software including CA can be replaced and upgraded via USB or online OTA. Support automatic and manual full frequency search, support single frequency search. The program can be classified according to different arrangement. Users can edit the program according to their preferences Support screen notifications, subtitles, email and other functions; Support for parental grading control and program locking. The remote control supports learning function, the linear distance of remote control can reach 15 meters, and the TV power and volume can be controlled by the remote control of the set-top box. The set-top box is equipped with 12V/DC external power adapter for easy maintenance and use SPECIFICATIONS  RF Input Port RF input Frequency  110-862MHz Input Resistance 75Ω Min Input Level ≤34dBuV（64QAM） Max Input Level ≥85dBuV Channel Bandwidth 8MHz C/N Value ≤28dB（64QAM，6.952Mbaud） MER Value ≤26dB Frequency Range ±150kHz Reflection Loss ≥8dB（tested onthe currently tuned channel of the RF tuner） Demodulation Auto 16，32，64，256 QAM（basic requirement ) Symbol Rate 3.6-6.952Mbaud（64QAM）  Multi-Video Output Port Video Output Range  700±30mV（p-p） Video Synchronization Amplitude 300±20mV（p-p） Amplitude-Frequency Characteristics ±0.8 dB（≤4.8MHz）；±1 dB（4.8-5MHz）；+0.5/-4 dB （≥5.5MHz） Differential Gain ≤8% p-p Differential Phase ≤ 8。 p-p RF Signal-to-Clutter Ratio (weighted weight) ≥56dB Luminance nonlinearity ±8% Chroma/Brightness Gain Difference ±5% Chroma/Brightness Gain Difference ≤50ns K Coefficient ≤4% Interface Module 2×RCA，HDMI1.4 with HDCP 1.3 TV System PAL D/K  Multi-Audio Output Port Audio Output Rang  ≥-8dBu（1kHz＋4dBu（-20dBFs）input） Audio Distortion Amp-FreqCharacteristics ≤1 Audio Amp-FreqCharacteristics +1/-2（60Hz-18kHz）；+1/-3（60Hz-20kHz） Audio Signal-To-Noise Ratio (Right Weight) ≥70dB Crosstalk (Audio Channels) ≤-70dB Phase Difference (Audio Channels) ≤5 Level Difference (Audio Channels) ≤0.5dB Volume Control 32degree Interface Module 2×RCA（L，R）   Smart Card Interface Adapter the ISO7816 compliant smart card interface (T=0 and T=14) for CA conditional access control systems.  System Resource CPU High performance double MIPS CPU FLASH MEMORY 8MB DDRAM 1Gb SOC Embedded Language Chinese, English  Decoding Support Channel Coding  RS Coding: RS ( 204 ， 188 ) Convolutional Interleaving Depth: I = 12 Convolution Interlacing Depth l cosine square root filter roll drop coefficient: 0.15 Video Coding Compatibility DVB Standard,Support MPEG-2 MP@ML/HL H.264 BP (with no ASO/FMO), MP& HP@ L3/L4.1 AVS Jizhun profile @ L6.0/ L4.0 AVS Broadcast profile @ L6.0/ L4.0 MPEG-4 SP Profile, Advanced Simple Profile @ Level 5 without GMC/Data Partitioning/Reversible VLC VC1 SP@ML, MP@HL, AP@L0~3 H.263 baseline profile JPEG decoder engine Audio Coding MPEG-1/2 Layer I/II/III Dolby AC3/AC3+ (optional1) DRA 2 CH/5.1 CH (optional1) Support mono, dual channel and stereo, mixing and so on DEMUX >= 16 PID Filter Decoder Support DVB General Unscrambling Algorithm Resolution /Display Ratio 1080P，1080I，4:3 ,16:9  Power Supply Module Demand Power  DC 5V or DC 12V Consumption <6W Plug BS
