ProStream 1000 with ACE

High-density solution for advanced stream processing and SD/HD transcoding


Harmonic’s ProStream® 1000 with ACE® is the industry’s first truly converged solution for advanced processing and transcoding of SD and HD MPEG-2 and MPEG-4 AVC (H.264) video and audio for broadcast and over-the-top (OTT) mobile/web applications, enabling the cost-effective deployment of next-generation services. This highly versatile and ultra-dense 1-RU device processing platform simultaneously transcodes video content for both broadcast and OTT mobile and web applications while providing unmatched video quality. In addition, the ProStream 1000’s power-efficient design helps operators reduce OPEX — and their carbon footprint, as it draws only 10 watts per HD channel and less than 3 watts per SD channel.

ProStream 1000 with ACE Features

Any-to-Any Transcoding

ProStream 1000 with ACE accommodates up to four ACE audio/video processing modules per chassis. Each module enables any-to-any transcoding of 60 SD or 20 HD broadcast services; up to 20 SD/HD inputs with 80 multiscreen output profiles; and Dolby® E, Dolby Digital, Dolby Digital Plus, AAC, HE-AAC and MPEG-1 Layer II audio codecs.

Optimized Multiscreen Workflows

ProStream 1000 with ACE fits seamlessly into a Harmonic multiscreen workflow, providing an optimized system for preparing content for adaptive bitrate streaming to IPTV and OTT devices. This flexibility helps users to simultaneously generate broadcast television services and mobile/web device profiles from a single compressed SD or HD input.

Advanced Statistical Multiplexing

Harmonic DiviTrackMX technology enables a multichannel, closed-loop, high-quality 4:1 HD and 16:1 SD “statmux in a box.” The DiviTrackIP option integrates multiplexing and IP switching by connecting ProStream 1000 units and Electra encoders across a LAN or WAN, allowing any ProStream 1000 in the network to efficiently manage remote and distributed encoders’ statmux pools.

Multi-Function Stream Processing

The ProStream 1000 advanced stream processing core provides enhanced IP, ASI and 8VSB remultiplexing, PCR generation, TS and mirroring, PSIP and DVB-EIT table manipulation, DVB-CSA and AES scrambling, and digital ad insertion over IP and ASI. The platform can be easily repurposed via firmware upgrades to support new applications.

Enhanced Audio Processing

Able to transcode any broadcast audio codec, ProStream 1000 with ACE addresses the most complex audio processing scenarios. For U.S. service providers, integrated Jünger Level Magic™ audio level adjustment enables compliance with the CALM Act by automatically eliminating audio level changes both within a channel and when switching between channels.
