Source. Compose. Deliver.
MediaCaster is a three-stage pipeline: ingest video sources, compose them into channels, and deliver multicast streams to every endpoint on your network.
Source
Ingest from video assets, ordered playlists, live HTML pages, or PowerPoint decks. MediaCaster normalizes every input into a composable video source ready for playout.
Compose
Layer HTML overlays onto video, switch between sources in real time, and manage playlists with scheduled playout. Composition happens in-engine with no external encoding hardware.
Deliver
Emit MPEG-TS multicast streams directly onto the venue network. BrightSign players, IPTV set-top boxes, venue monitors, and Q-SYS receivers pick up the stream natively.
What MediaCaster does.
A purpose-built streaming engine for the demands of live venue environments where timing, reliability, and operational simplicity are non-negotiable.
Multicast MPEG-TS Output
Native multicast transport stream output to IP multicast groups. Designed for IPTV headend environments and digital signage networks where every millisecond of latency matters.
Playlist Management
Build and schedule ordered playlists of video assets, image sequences, and mixed media. Define playout order, duration, and transition timing for fully automated channel origination.
HTML Overlay Composition
Composite live HTML content over video sources in real time. Render data-driven overlays, tickers, branding, and dynamic graphics directly within the streaming pipeline.
PowerPoint Ingest
Import PowerPoint decks as channel sources. Operations teams can author content in the tool they already know and feed it directly into the playout pipeline without conversion steps.
Multi-Source Switching
Switch between video sources, playlists, and HTML pages in real time. Operators can respond to live event conditions and cut between content without interrupting the output stream.
Scheduled Playout
Time-based automation for unattended operation. Schedule channel content changes, playlist rotations, and source switches to align with event timelines and venue programming.
Built for the demands of live.
Rust-Based Streaming Engine
MediaCaster v2 is a ground-up rewrite in Rust, chosen for its memory safety guarantees, zero-cost abstractions, and predictable performance under load. In a sports venue, a dropped frame or a GC pause during a critical moment is not acceptable. Rust eliminates entire classes of runtime failures by design, giving operators confidence that the streaming engine will perform identically on the first pitch and the last out.
Design Principles
Dual-Mode Deployment
MediaCaster operates in two modes. As a standalone product, it serves as a complete multicast streaming appliance — point it at your sources and it delivers channels to your network. As an embedded component of the Mediacast platform, it integrates with CastControl for centralized management, scheduling, and monitoring across an entire venue. Same engine, two deployment models, one operational workflow.
Deployment Options
Live at Yankee Stadium.
MediaCaster is not a prototype. It runs in production at one of the most demanding venues in professional sports.
Yankee Stadium
Bronx, NY
MediaCaster powers IPTV channel origination and digital signage delivery across Yankee Stadium, running alongside CastControl as part of a complete venue media platform. Every suite, concourse display, and back-of-house monitor receives its content through MediaCaster multicast streams.
Proven Under Pressure
Sports venues are the hardest test for streaming infrastructure. Content must be on-screen before the play starts, not after. Source switches must be seamless. Failures must be invisible. MediaCaster was designed for this environment from the beginning — not adapted to it after the fact.
Streams to everything on your network.
MediaCaster delivers standard MPEG-TS multicast — any device that speaks IGMP can receive the stream.
BrightSign Players
Native multicast MPEG-TS reception for digital signage and IPTV display across suites, concourses, and premium spaces.
IPTV Set-Top Boxes
Standard STB endpoints receive MediaCaster channels as part of the venue IPTV channel lineup, no middleware changes required.
Venue Monitors
Direct-to-display multicast for back-of-house, production, and operational monitoring applications across the venue.
Q-SYS Receivers
Integration with QSC Q-SYS for audio extraction and AV distribution within unified venue control system environments.
Built in the open.
MediaCaster started as an open source project and that heritage shapes how we build it. Transparency in tooling builds trust with the operators and engineers who depend on it daily.
Open Heritage
MediaCaster's original codebase is available on GitHub. The v2 Rust engine carries forward the same philosophy: operators should be able to understand, inspect, and trust the systems they depend on. No black boxes in the signal chain.
Community & Contribution
MediaCaster exists because venue engineers needed tooling that proprietary vendors weren't building. If you're solving similar problems in live venue environments, we welcome contributions, feedback, and conversation about the direction of the project.
