With Harmonic’s DiviTrackMX™ statistical multiplexing technology, the ProStream 1000 delivers highly efficient VBR service without the need for any additional equipment—allowing operators to build architectures based on their needs, not budget constraints.
The DiviTrackMX re–encoding technology enables VBR–to–VBR or CBR–to–VBR bit rate changing as well format changing of pre-encoded MPEG-2 video streams while maintaining high video quality. Sharing the same technology as Harmonic’s award-winning DiviCom® encoder line, the DiviTrackMX Re-encoding processor leverages the knowledge and experience gained from several generations of encoders.
 With its standard IP and DVB-ASI input and output interfaces, the ProStream 1000 can be easily incorporated in any existing headend environment and support any digital turnaround architecture. The ProStream 1000’s robust, extensible and highly scalable design supports MPEG re-multiplexing functionality, including PID remapping and filtering, insertion of PSI/SI tables, PID multicast, service redundancy as well multiple IP sockets containing MPTS and SPTS. This configuration not only reduces rack space and power requirements, but also simplifies network infrastructure while delivering a high-availability solution.
 The ProStream’s industry-leading SimulCrypt Synchronizer core (SCS) supports DVB SimulCrypt versions 1, 2 and 3, and allows for the simultaneous connection of up to ten different CAS from different vendors.
Fully integrated with all leading CAS vendors and compliant with widely implemented industry protocols, the ProCipher scrambling technology is known in the industry for its stability, and high performance.
The ProStream 1000 with ProCipher IP and ASI scrambling technology is designed to multiplex and scramble any format of video, audio and data elementary streams (e.g. MPEG-2, MPEG-4 AVC, AC-3, AAC, AACPlus). The solution easily integrates into existing or new architectures, and reduces cost and complexity by eliminating the need for multiple devices or software-based IP scrambling solutions in distributed cable, satellite or telecom networks.
A DiviTrackIP engine enable the ProStream-1000 to support Statistic Multiplexing over LAN and WAN networks, including support for up to 24 services per statistically multiplexed pool and support for up to three pools within a single transport stream.
Unequalled performance and highly accurate bit-rate controlling, enable the ProStream 1000 to distribute MPEG traffic for Single Frequency Networks (SFN) from one central Headend, over an IP network, to multiple remote DVB-T SFN Headends
Management
Through a local management interface Harmonic’s NMX Digital Service Manager™ controls the primary and backup ProStream units in a redundant architecture. Together with NMX, the ProStream supports 1:1, N:1 and N:M redundancy schemes..
Three IP 100Base-T Ethernet interfaces are
available for connection to the Conditional Access
System (CAS) as well as to the management and
control network. Through the CAS IP interface the
ProStream 1000 communicates with the ECMGs
and EMMGs for exchange of control words, ECMs
and EMMs.
