TVU MediaHub Quick Start User Guide

TVU MediaHub’s cloud-centric and hybrid architecture supports limitless inputs and outputs, effortlessly managing intricate signal matrices in SDI and IP formats.

Product overview

TVU MediaHub is a cloud-native, hybrid video router designed to bridge the gap between traditional hardware-dependent SDI routing and modern IP-based digital workflows. It is a SaaS-based solution that allows broadcasters to manage, scale, and route video signals with “boundless” input and output capabilities.
This MediaHub QSUG describes several “opt-in” features. Please contact TVU Support for more information about availability.

Core capabilities

MediaHub functions as a virtual routing switcher. Unlike traditional hardware routers limited by physical ports, MediaHub offers:

• Protocol-Agnostic Routing: Accepts and converts between various formats including SDI (via edge devices), NDI, SRT, TVU Grid, RTMP, HLS, and even YouTube/social media feeds.
• Infinite Scalability: Allows for an unlimited number of inputs and outputs by utilizing cloud resources on demand.
• Automated Signal Processing: Automatically handles encoding, decoding, scaling, and frame-rate conversion the moment a source is added.
• Advanced CBR for SRT Listener and Caller modes (opt-in): The Advanced CBR for SRT Listener and Caller modes allow enhanced receiver compliance.

Supported protocols

MediaHub is designed to be protocol-agnostic, acting as a “universal translator” between traditional broadcast standards and modern IP streaming formats.
Because it is a cloud-native platform, it can handle both compressed and uncompressed formats by utilizing either cloud compute or on-premises edge devices.

Supported input protocols

MediaHub can ingest virtually any live video source. Note that physical SDI/SMPTE connections require a TVU Transceiver or Edge device to bridge into the cloud environment.

• Broadcast & Professional IP: NDI, SRT (Caller/Listener), TVU Grid (proprietary low-latency), UDP (Unicast/Multicast), RTP-FEC, ISSP, MXL.
• Physical & Standardized: SDI (via edge device), SMPTE ST 2110 / ST 2022-6 (via edge device).
• Web & Streaming: RTMP, RTMPS, HLS, RTSP, Zoom Meeting, HTML.
• Cloud & Social: YouTube, Facebook, TikTok, Twitch, X, Kick, and Other (custom URL/stream).
• TVU Ecosystem: TVU One, RPS One, TVU Anywhere, TVU Pack, TVU Grid (Grid-Pack / Grid-SDI / Grid-MediaHub), and TVU Channel — added via the TVU Device source type.

Supported output protocols

MediaHub can simultaneously route a single input to an unlimited number of destinations, each with its own protocol and encoding profile.

• Streaming & CDN: RTMP(S) Push, RTMP(S) Pull, HLS Push, HLS Pull.
• Professional IP: NDI, SRT (Caller/Listener), TVU Grid, UDP, RTP-FEC, ISSP, MXL.
• Broadcast Delivery: RTSP Push, RTSP Pull.
• Physical Output: SDI (requires a TVU Transceiver for decoding).
• TVU Ecosystem: TVU Pack (Return Video Feed / VoIP).
• Direct Social Media: Native API integration for “Direct” posting to YouTube, Facebook, Twitch, X, and Other.

MediaHub Open API features

The TVU MediaHub Open API is a set of programming interfaces designed to allow broadcasters and developers to automate, customize, and integrate the MediaHub routing engine into larger media supply chains.

Rather than relying solely on the drag-and-drop web interface, the Open API allows for programmatically managing complex signal matrices, which is essential for large-scale operations or software-defined master control rooms. Users can also use the Open API to integrate capabilities within our ecosystem with their workflow via API calls.

Key API functional areas

• Routing Control: Trigger “Connect” or “Disconnect” actions programmatically to start/stop live routes between sources and destinations.
• Output Provisioning: Create, delete, and modify output destinations (e.g., generating a new RTMP, HLS, or SRT endpoint on the fly).
• Encoding Profiles: Define technical parameters for routes, including bitrate, resolution, and frame rate. Profiles can be pre-created via the UI or dynamically generated via API.
• Source Management: Register new input sources (SourceObjects) into the router database to make them available for routing.
• Folder Integration: Group multiple output destinations into a “Folder” for batch management and simplified orchestration (start/stop the whole group at once).

MediaHub primary software features

TVU MediaHub is defined by its transition from a simple routing tool to an intelligent orchestration hub. The software features focus on eliminating the technical barriers of traditional hardware (like port limits and manual patching) through automation and a visual-first approach.

Key features:

• Drag-and-Drop and One-Click Routing: An object-oriented visual UI that lets non-technical staff route complex signals without specialized engineering training. Operators can either drag a source onto a destination or click the Route button on a source to send it to one or multiple output destinations at once — enabling fast one-to-many distribution with no manual patching.
• Real-Time Previews: Users can see live thumbnails of all sources and destinations within the routing matrix to ensure the correct feed is being switched.
• Integrated AI Tools: MediaHub emphasizes integration with TVU’s AI ecosystem, enabling automated ingestion, transcription, and indexing of live feeds.
• Hybrid Architecture: Can run entirely in the cloud, on-premise in data centers, or in a hybrid configuration to maintain low latency for local SDI environments.
• Analytics & Redundancy: Includes a dashboard for monitoring bandwidth and signal flow, with built-in redundancy that automatically triggers backup paths if a signal is lost.

Visual routing and management

• Object-Oriented UI: MediaHub uses a workspace where inputs and outputs are visual objects. You route signals by literally “drawing” a connection between them.
• Live Thumbnail Previews: Every input and output on the interface displays a real-time, low-latency video thumbnail. This allows operators to verify content visually before switching it to a live destination.
• Destination output and source sharing: Users can now share access to their sources and outputs with other users and subgroups within the same root group.
• Infinite I/O Scaling: The software doesn’t have a fixed matrix size. You can “spin up” new software-defined ports on demand as your production grows.
• Latency: Maintains sub-second latency across most IP-to-IP routes, specifically optimized when using TVU’s ISX (Inverse StatMux) technology.
• Deployment: Cloud (SaaS), On-Premise, or Hybrid.

Automated signal processing (the “invisible” features)

• Auto-Conversion (UDX): The software automatically detects the source resolution/frame rate and matches it to the destination’s requirements. It handles Up/Down/Cross conversion in the background without needing external gear.
• Protocol Bridging: MediaHub acts as a universal translator. It can take an NDI source and simultaneously output it as an SRT stream for a remote studio and an RTMP stream for YouTube.
• Dynamic Resource Allocation: The software intelligently manages CPU/GPU cores. It only consumes processing power when a route is active, which powers the “pay-as-you-go” pricing model.

Operational control and automation

• Advanced Scheduling: You can pre-program routing changes based on a calendar. For example, the software can automatically switch an output from a “Pre-game” feed to a “Game-start” feed at a specific time.
• Redundancy & Failover (opt-in): The software monitors signal health. If an input feed drops, it can be programmed to automatically switch to a backup source (e.g., a “Slate” or a secondary SRT feed).
• TVU Pack mode (opt-in): TVU Pack is a new destination type. Users can send any video to a TVU Pack as a return video feed or a Voice over IP (VoIP).
• Workflow builder (opt-in): The Workflow builder assists users and support by providing troubleshooting tools to assist with a specific input or output. When selecting an input destination and Workflow Management icon, the Workflow Studio page opens in a new tab . The new tab shows a graphical representation of the underlying modules that are running and their status.
• Enhanced SCTE and metadata transmission: SCTE and closed caption metadata cross box pool transmission optimization.

Ecosystem integration (TVU Cloud Services)

• TVU Search Integration: Automatically sends routed feeds to TVU Search for AI-driven transcription and metadata tagging.
• TVU Producer: Feeds from MediaHub can be sent directly into the TVU Producer cloud switcher for multi-camera live production.
• Analytics Dashboard: A built-in software module that tracks bandwidth usage, signal stability, and routing history for data-driven post-show analysis.
• TVU Agent integration: TVU Agent enables SDI Input/Output functionality or to deploy MediaHub on your infrastructure.

Opt-in features overview

The opt-in features listed below are not enabled in the default, Project-based, modules described in Chapter 1. The “opt-in” features refer to specialized advanced processing tools and microservices that are not enabled by default but can be activated in the user interface to enhance video quality or workflow automation.

Note: Users must contact TVU Support to enable these features.

• InSync Advanced Frame Interpolation: The most prominent opt-in feature is the native integration of InSync Advanced Frame Interpolation. It’s advantages are simple activation, motion-compensated conversion, deinterlacing, and standards conversion.
• Self-hosted Static IP: Static IP assignments are region-specific and can only be requested by Group Admins. Contact support for more information.
• UHD Processing: As seen in your earlier configuration window, UHD (4K) encoding support is a selectable microservice toggle for high-resolution workflows.
• TVU Pack mode (opt-in): The TVU Pack has been added as a new output destination type for MediaHub. Users will be able to send videos to TVU Packs as either a Return Video Feed, or Voice over IP (VoIP).
• Redundancy & Failover (opt-in): The software monitors signal health. If an input feed drops, it can be programmed to automatically switch to a backup source (e.g., a “Slate” or a secondary SRT feed).
• Color correction feature: TVU MediaHub color correction is part of the platform’s advanced video processing toolset, designed to ensure that any IP or SDI source meets professional broadcast standards. The platform provides both manual and AI-powered tools to manage signal integrity.
• Workflow builder: MediaHub introduces an optional UX and graphically-based workflow that better matches how a significant amount of users operate.
• VLAN service: For specific networking needs, users can enable VLAN Service through the receiver software integration.
• Advanced CBR output for Listener and Caller: We have introduced an Advanced CBR output option that has already shown a significant reduction in continuity error counts and improved overall SRT compliance.
• Open API Integration: For advanced users, MediaHub offers an opt-in for open API connectivity, allowing third-party tools to handle scheduling and monitoring.

Workflow and AI Microservices

While many core functions are automated, several operational features can be considered opt-in depending on the production’s needs:

• AI-Driven Active Search: Users can opt into using Active Search profiles that automate actions like creating video clips, sending notifications, or applying tags based on specific AI-detected criteria.
• Cloud Recording: Instant capture of live feeds for archival or rebroadcast can be activated as a specific destination microservice.
• Scheduling: Operators can opt to use the Scheduling tool to preplan and automate routing operations in advance.

InSync Advanced Frame Interpolation

Activating this feature triggers a high-performance, CPU-based processing layer that provides several professional-grade benefits:

• Advanced Motion Compensation: It provides high-end motion-compensated frame rate conversion, which is particularly useful for smooth transitions between 50fps and 60fps in live sports.
• High-Quality Deinterlacing: Seamlessly handles traditional interlaced formats (like 1080i) by converting them into modern progressive workflows (like 1080p) without typical visual artifacts.
• Low-Latency Conversion: Unlike hardware converters that can add several seconds of delay, this integrated service maintains a sub-second latency (approximately one second).
• Cost Efficiency: Since it is embedded in the MediaHub UI, it eliminates the need for expensive external standards conversion hardware.

Enabling InSync Advanced Frame Interpolation

To find and enable these enhancement tools for your source, follow these steps within the workspace:

1. Click on the specific Destination block in the right panel that requires enhancement. The configuration window opens.
2. Within the configuration window, look for the Microservice section in the right panel.
3. To Enable the Service, move the InSync: Advanced Frame Interpolation slider to the right until green.

4. Configure the encoding profile settings (If needed): Once enabled, you can define your target parameters, such as converting from 50fps to 60fps or switching from interlaced to progressive scan modes.

Note: the default Encoding profile cannot be configured. If needed, a new encoding profile can be created.

Workflow builder

workflow builder. While MediaHub and Workflow Studio are distinct tools, they are part of the same unified ecosystem, allowing you to move between routing and advanced workflow orchestration.
The Workflow builder assists users and support by providing troubleshooting tools to assist with a specific input or output.

How to access Workflow Studio

To access Workflow Studio from MediaHub:

1. Select a Source block in the Source panel.
2. The Source configuration window opens. Click the Workflow builder service icon at the top right of the window.

3. The Workflow Studio page opens in a new tab.

Passthrough Transport Option

The encoding profile drop-down menu now includes an improved “passthrough” transmission option. This option allows output without PID re-mapping or re-muxing. Users can identify which outputs support passthrough.

TVU Agent installation

The TVU Agent is a lightweight software module used across all TVU SaaS products, including MediaHub and MediaMesh. It enables your local hardware to connect to the cloud, allowing seamless resource usage and control.

Users will first need to contact TVU Support to install the Agent. As a MediaHub user, the SDI Input source does not require TVU hardware to enable a device’s SDI input or output.

TVU Agent installation includes the following steps:

• Step 1 – Log in to the TVU Home user interface
• Step 2 – TVU Agent Installation
• Step 3 – Execute the installation command
• Step 4 – Activating the TVU Agent
• Creating additional Box Pools
• Box Pool port mapping
• MediaHub verification and testing
• Troubleshooting

TVU Home

In the TVU Networks ecosystem, TVU Home (often accessed via home.tvunetworks.com) serves as the centralized management portal and unified authentication layer for all TVU cloud-native services, including MediaHub.

The integration is designed to move the user from “buying a product” to “managing a workflow.”

Here is how MediaHub integrates with TVU Home:

Single Sign-on SSO and Unified Access
TVU Home acts as the gateway. Once you log in to TVU Home, you have immediate access to the MediaHub interface without secondary logins. This integration ensures that:

• Permission Syncing: User roles and permissions defined in TVU Home (e.g., Admin, Operator, Guest) automatically apply to MediaHub routing capabilities.
• Resource Centralization: All your available “sources” (like TVU One backpacks or TVU Anywhere apps) registered under your TVU Home account automatically appear as available input pins in the MediaHub interface.

Resource & License Management
MediaHub introduces a utility-based (SaaS) pricing model, and TVU Home is where this is managed:

• Core Allocation: From the Home portal, you can monitor and manage how many processing cores are allocated to MediaHub.
• On-Demand Billing: You can track your “pay-as-you-go” usage (per-minute routing) through the billing and subscription modules within TVU Home.

Ecosystem “Bridge” Functionality
TVU Home allows MediaHub to act as the “bridge” between other TVU apps:

• TVU Search: You can route a signal in MediaHub and, via the TVU Home back end, immediately see that feed appear in TVU Search for AI-driven clipping and transcription.
• TVU Producer: From the Home dashboard, you can launch TVU Producer and use MediaHub to feed it with diverse IP sources (SRT, NDI, or RTMP) that were converted or bridged in the Hub.
• TVU Command Center: MediaHub’s status, health alerts, and signal analytics are aggregated into the Command Center view available within the Home portal.
