DTV Headend Equipment

H306 DVB Scrambler

BOY-H306 DVB Scrambler is specially developed for BOY's digital- television headend total solution, which is fully compliant with ISO/IEC-13818. By adopting the DVB Common Scrambling Algorithm, it could scramble all the TS (Transport Stream) coming from MUX and other headend equipments, including satellite receiver, digital encoder and other video service equipments. Working together with SMS (Subscribers management system), inserting EMM and ECM information of CA (Conditional Access), it could realize the wire or wireless television program conditional access and prevent illegal authority access to the scrambled video and data stream. BOY-H306 input/ output interfaces is compliant with DVB ASI standard and the LAN control and monitoring are achieved by TCP/IP, SNMP and HEMS*. (* Head-end Equipment Management System, a BOY' s proprietary software) Features * Comply with ETR289 standard * Support scramble nominated program or transport stream. * Support Simulcrypt Mode and multicrypt CA systems * Have perfect function for MPEG transport stream analyzing * Support re-process the PSI/SI info in transport stream * Support protect the TS from ASI input/output * Adaptive Bit Rate, re-adjustable and re-signable PCR * Support real time remote monitor the TS * Auto-switchable Input backup * 188/204 auto-adaptable Package * PCR correction Rear panel Diagram DCH-3000TP digital TV scrambler does the process of scrambling to transport stream via CW (Control Word) and the whole process is the protection process to the CW. In MPEG-2 digital TV system, the conditional access could be realized via two data stream. ECM (Entitle Control Message) and EMM (Entitle Manage Message). After scrambled via SK (Service Key), the CW will be transmitted in the ECM, which including the program source, time, content catalog and program price information, etc. After scrambled via PDK (Personal Distribute Key), the SK will be transmitted in the EMM, which including the address and subscriber authorization information.
