How Harmony Hub Helps

IT Professionals and Clerks

With many plenary and committee meetings to manage, webcasting and archiving video content can be a challenge. Our Harmony Hub is specially designed to make this job a breeze. Harmony Hub is a turnkey solution that is specially designed to make live and on-demand streaming and archiving reliable and painless to use.

In addition to streaming proceedings and automatically publishing archives, Harmony Hub provides a simple-to-use program guide for system users to follow. Behind the scenes, session schedules and indexes can be automatically synchronized from external systems or used in our own interfaces to seamlessly deliver a simple end-user experience.

Compatible with virtually all enterprise environments, Harmony Hub uses a flexible distributed architecture that allows you to leverage as much or as little of your own existing infrastructure as you please. Fully compatible with virtualization technologies, Harmony Hub is Microsoft Windows Server compatible and integrates smoothly into small and massive enterprise ecosystems alike.

What you need to know


Streaming and recording audio and video in a highly reliable manner is the basis of our solution. Recorders automatically archive recordings based on an easy-to-use web-based scheduling interface and are highly tolerant to user error thanks to our loop recording buffer. Multiple tracks of audio and high definition video are supported where required. Multi-format and multi-bitrate configurations enable support for a wide variety of mobile and fixed devices.


Optionally, during a meeting a clerk or secretary can add indexes related to agenda items, people, bills, comments and more. Additionally, this data can originate from mixing boards and third party systems such as touch-screen voting products. Indexes are timestamped so they can be linked to video once published. If required, indexes can be added to recordings after the fact.


When a large number of meetings are going on at the same time, it's critical that monitoring and measurement are part of the delivery process. Our Hawkeye and Hawkeye Live modules provide automated availability and visual confidence monitoring. Picture the control room in a TV station with a wall of video and you'll understand the degree of oversight that this affords you. You will never miss a recording due to a downed encoder, room change or switching problem again.


As meetings are scheduled, they instantly show up in the Harmony Hub web-based program guide. Access is "gated" to allow visibility to live streams when appropriate. Within a few minutes after the end of the recording, archives are made available. Indexes can be added immediately or after the fact.


  • SliqScribe is a workflow accelerator for the production of written transcripts of meetings, conferences and other events. It is designed to take advantage of automated speech recognition (ASR) during the meeting and indexing in the recording. Once completed, our Harmony Hub platform provides indexing and searching capabilities to produce a searchable, structured audio transcript in seconds. We also provide transcription tools that can be used in conjunction with SliqScribe to generate automatic or manual transcripts from any recordings.

The Sliq Harmony Hub solution is a feature-rich distributed software platform that is controlled from a central web interface. Based on Microsoft Windows Server and Microsoft SQL Server, the solution uses a combination of resilient grid and node clustering to provide a high level of fault tolerance. Modern scaling techniques ensure that the platform easily scales to serve content on a daily basis to millions of constituents. Additionally, public facing data is replicated in a cachable XML format for security and massive scalability. While most of the platform runs on application servers, some client applications are part of the solution for indexing, transcription and workgroup collaboration. Harmony Hub can be run on self-hosted virtual environments, on Sliq supplied cloud servers or on any combination of these options. Server components can run under virtualization without issue.


The most critical parts of the Harmony Hub solution are the services that record and archive audio and video. In most cases this is our Razorback recording node but if audio-only recording is required then our AudioLogger provides the same function. We designed and built our encoders from scratch so that we could tightly control every detail and make sure that they were rock solid. Supporting multiple audio tracks and multiple video bitrates, Razorback can encode and deliver video streams to the vast majority of mobile and fixed devices. Archive streams at resolutions up to 1080p are possible as well. Razorback and AudioLogger both record in a loop fashion using a ringbuffer so that nothing is ever lost due to venue changes or human error. Some customers who prefer a more compact server footprint choose to encode multiple venues on a single unit. Sliq can provide a turnkey hardware encoder with SDI or analog video inputs or optionally customers can provide their own hardware. Meticulous attention to detail and extensive testing have resulted in a product that you as a customer can depend on much like our existing customers who have recorded millions of hours without missing a beat.

API Integration

Web API allows for easy management of the Harmony system through the ability to build custom tools for tasks such as scheduling, meeting management, and much more.

Cloud or Self Hosting

The majority of our customers record at least a portion of their in-camera/private proceedings so for them a pure cloud hosted solution is not an option. Additionally by leveraging existing server, storage and virtualization infrastructure, our customers enjoy great cost savings as their media archives start to accumulate over time. While we do provide a pure cloud hosted option, we leave the choice up to you to decide what's best for your organization.
