Technical Specifications
Key features
 Fast channel change time: 0.2-0.5 sec on Broadcom platform1
 Key-frame indexing
 Smooth transition from TCP unicast to DVB-C
 Supported stream encodings: MPEG2, MPEG4 AVC/H.264, HEVC/H.265
 Compatible with Verimatrix scrambled streams (and other scrambling systems that preserve key-frame
identification patterns)
 Easy integration. Software library on the client side.
 Monitoring and statistics
 Redundancy support
Protocols
 Channel reception using DVB-C on STB side and UDP Multicast streams on server side.
 MPEG2 TS (Transport Stream)
 TCP connection is used between the server and client to retrieve initial burst data
Scrambling
 Compatible with Verimatrix encrypted streams
 Compatible with scrambling systems that preserve key-frame identification patterns in Transport Stream
Redundancy
 Failover support. When the primary FCC server is not available, client will automatically switch to the secondary
FCC server.
Smooth transition
 After the initial burst, client will switch to the DVB-C stream at the exact transition point in Transport Stream to
ensure smooth transition. Transition time from TCP unicast to DVB-C is about 5 seconds2

Integration
 Software library based integration (statically linked library for different platforms)
Management
 Web GUI configuration utility with DB support.
 Command line tool to detect and configure channel parameters automatically
 Comprehensive log file output
 Comprehensive monitoring and statistics support
System requirements
 Operating System: Linux (RHEL/CentOS recommended)
 20MB RAM per channel
 1MB RAM per client
 NIC's must provide enough network throughput to handle simultaneous channel changes. Each channel change
requires about 2MB of data burst.
Performance
 100 Gbps per server (total TCP traffic for initial burst) 3
 Up to 300 000 concurrent clients per server4
 Up to 2000 channels per server5
1. Actual channel change time depends on stream bitrate and encoding options, video decoder settings of the player application, and network bandwidth.
2. Exact transition time depends on multiple factors: network bandwidth between the client and server, stream bitrate, DVB-C tune time.
3. Performance test has been done on Intel Xeon based server with 2x CPU, 18 physical cores per CPU, 36 physical cores total (72 hyper-threading cores)
4. Exact count of maximum concurrent clients depends on available RAM and CPU performance.
5. Channel count is limited by available RAM and CPU performance.
