Cross-Platform AV Experience Across Devices with One Codebase
ProAV vendors and integrators are forced to maintain separate apps for Windows, macOS, mobile, and web, drifting UX and features that ship to one device months before the rest. Streaming, monitoring, and configuration can be scattered across inconsistent tools.
Promwad develops cross-platform AV applications on a native core + cross-platform UI layer: shared product logic written once, with native performance and an identical experience across PC, tablet, mobile, web, and embedded panels. You ship faster, maintain less, and give every user the same flawless AV experience.

What We Build
Any Pro AV Workflow — Delivered as One Cross-Platform Application
We take the control surfaces, dashboards, players, and configuration tools that power your AV systems and engineer them as unified applications that run identically on desktop, mobile, web, and embedded panels — from one shared codebase.
Control & management consoles
The operator-facing layer for routing, switching, and running your AV systems. We build cross-platform control consoles for IPMX-based video distribution, hybrid SDI/IP environments, and multi-vendor Crestron rooms — so the same interface drives the room whether it's opened on a touch panel, a laptop, or a phone.
Monitoring & analytics dashboards
Real-time visibility into your AV estate — stream health, device status, latency, bandwidth — alongside audience and engagement insights. We turn edge AI pipelines and signage telemetry into clear, responsive dashboards your teams and advertisers can read on any screen.
Streaming & playback clients
Low-latency players and preview clients for live and on-demand AV — multiview, confidence monitoring, and content playout. We build NDI-, IPMX-, and WebRTC-ready clients that behave consistently across operating systems and form factors, with hardware-accelerated decode where it counts.
Configuration & provisioning tools
The setup and lifecycle layer — device onboarding, scene templates, content scheduling, and software-defined audio control. We build configuration and provisioning apps for digital signage networks and virtual audio mixers, so integrators reconfigure entire deployments quickly and repeatably from a single interface.
Why Promwad
AV is becoming software-defined, multi-device, and IP/AI-driven. Maintaining a separate native application for each operating system no longer scales — every new feature multiplies cost, and UX consistency erodes with each release.
Promwad solves this with an architecture built for the next decade: one engineering effort that runs everywhere, without compromising on speed or reliability.

Application Areas
Cross-Platform AV Software for Real-World Operations
Corporate & Enterprise
Give teams one app to control hybrid meeting rooms from a laptop, phone, or in-room panel — consistent UX, simplified device control, and flawless connectivity across platforms.
Hospitality
Centralize AV-over-IP management across hotels, resorts, and venues. Staff operate the same intuitive interface on any device, cutting training and maintenance overhead.
Retail & Digital Signage
Control and monitor display networks from web and mobile dashboards — push content, track status, and adjust signage remotely with full visibility.
Public Venues & Live Events
Equip operators with mobile and tablet control surfaces for fast, reliable AV operation — remote monitoring dashboards, low latency, and instant synchronization across the floor.
AI-Powered AV, on Every Screen
From Edge Intelligence to Actionable Dashboards
Promwad brings AI-driven insight into your cross-platform applications — surfacing what happens in the room as data your operators and advertisers can act on from any device.
We engineer edge AI pipelines on SoCs, AI accelerators, and FPGA platforms, then expose their output through real-time dashboards that read identically on desktop, web, tablet, and mobile.
Audience & engagement insights
presence detection, audience counting, dwell-time, and attention estimation as live dashboard metrics.
Adaptive, event-driven AV
AI triggers that adapt content, pacing, or routing in real time, controlled from your cross-platform app.
Room & meeting intelligence
auto-framing, speaker tracking, and occupancy analytics unified across every endpoint.
Privacy-first by design
edge processing keeps video on-device, cuts bandwidth, and runs offline at low latency.

Key Transformation
From Fragmented Apps to One Unified Codebase
Most AV software grows into a maintenance burden: separate native teams, UX that drifts apart, feature parity that lags for months, and a total cost of ownership that climbs with every platform you add.
Promwad's cross-platform AV development consolidates that effort into a single, scalable foundation — without forcing a risky rewrite.
Our approach:
- Build a shared cross-platform core that holds business logic and real-time media handling
- Use native modules only where raw performance demands it
- Apply one design system so the UX stays identical on every device
- Set up multi-platform CI/CD for synchronized, simultaneous releases
- Migrate existing applications in phases — extending what works, replacing only what doesn't

Case Studies
Video Conferencing App with Cross-Platform Picture-in-Picture
WebRTC-based conferencing solution spanning 10+ platforms — from smart TVs and STBs to iOS and desktop
Problem
Our client needed a video conferencing solution that could deliver picture-in-picture functionality across heterogeneous endpoints — smart TVs (Tizen, WebOS), Android STBs, desktops, and mobile — without fragmenting the codebase.
Solution
Promwad designed and built a cross-platform WebRTC application using Kurento media server for multi-room conferencing, GStreamer for codec pipelines, and a DIAL-based mobile companion app that turns any iOS or Android device into a camera source with smart TV as the display output.
Result
The client shipped a product supporting 10+ platform targets — Linux, Windows, macOS, RDK, AOSP, AndroidTV, Tizen, WebOS, Android, and iOS — opening addressable use cases in enterprise meetings, online fitness coaching, and co-viewing entertainment.
