Designed to address the increasing demand for advanced video and audio services, Harmonic’s IP-based ProStream™ 1000
stream processing platform is the ideal platform for multiplexing, scrambling and advanced processing of MPEG streams.
The multi-functional and higly versatile ProStream 1000 is a modular and compact 1-RU system with five slots at the back
which can be populated with ASI or IP (Gigabit Ethernet) cards.
Multiplexing
With its standard IP (Gigabit Ethernet) and DVB-ASI input and output interfaces, the ProStream 1000 can be easily
incorporated in any existing headend environment or as part of any digital turn around (DTA) architecture. 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, and service redundancy, as well multiple IP sockets containing MPTS and
SPTS. This configuration not only reduces rack space and power requirements, but also simplifies the network infrastructure
while delivering a high-availability solution.

Operators of all types can take advantage of the flexibility of the ProStream 1000 for applications that include:
- Multiplexing in any existing headend environment and utilized as part of a digital turnaround (DTA) architecture (Multiplexing)
- Integrated closed-loop statistical multiplexing of up to 64 channels in multiple DivitrackMX™ pools offers service providers a high quality service in contrast to legacy rate-shaping technologies (ProStream 1000 with DiviTrackMX)
- A DiviTrackIP™ engine enables the ProStream 1000 to support statistical multiplexing over LAN and WAN networks, including support for up to 24 services per multiplexed pool, and support for up to three pools within a single transport stream.
- Reducing cost and complexity by eliminating the need for multiple devices or software-based IP scrambling solutions in distributed cable, satellite or telecom networks, including support for AES encryption (ProStream 1000 with ProCipher Scrambling)
- Bulk descrambling to distribute a large amount of content (hundreds of services) to small IPTV and cable headends via satellite, in a secure manner (ProStream 1000 with ProCipher Scrambling)
- Delivering multiple switched broadcast services through their VOD infrastructure by converting existing VBR services to CBR with video quality superior to legacy rate-shaping technologies (ProStream 1000 with Mentor™ Re-Encoding)
- Distributing MPEG traffic for single frequency networks (SFN) from one central headend, over an IP network, to multiple remote DVB-T SFN headends (SFN over IP)
