Any-to-Any Transcoding
ProStream 1000 with ACE accommodates up to four ACE audio/video processing modules per chassis. The platform enables any-to-any transcoding of:
-
60 SD or 20 HD MPEG-2 or H.264 broadcast services per RU
-
Up to 20 SD/HD inputs with 80 multiscreen output profiles per RU
-
Dolby® E, Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3), AAC, HE-AAC, 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 maximize the value of their content by providing the ability 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.” Our 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
In addition to unmatched transcoding performance, the ProStream 1000 advanced stream processing core provides enhanced IP, ASI and 8VSB remultiplexing (including PID remapping, PID prioritization and filtering), 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 driven by the ongoing evolution of video service delivery, which makes it a smart choice for CAPEX investement.
Enhanced Audio Processing
Able to transcode any broadcast audio codec, ProStream 1000 with ACE addresses the most complex audio processing scenarios, such as transcoding from MPEG-1 Layer II to AC-3 or HE-AAC. 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 (such as during commercial breaks) and when switching from one channel to another.
