Building a real-time, enterprise-grade TV broadcasting platform with seamless playout, intelligent media management, and a live-sync dashboard.
Challenges
Building a continuous broadcasting system requires extreme precision and a highly reliable backend. We faced several critical engineering challenges:
- Zero-Delay Playout: Cron-based systems introduced lag and black screens between videos.
- Media Race Conditions: Concurrent downloads caused file corruption and bandwidth waste.
- Storage Overload: 24/7 streaming quickly consumed disk space.
- Real-time Sync: Polling-based dashboards overloaded the database.
Solution & Key Features
Real-Time Analytics Dashboard
A live dashboard providing instant visibility into channel status, viewer metrics, and system health without page reloads.

In-Memory Playout Engine
We bypassed traditional cron jobs and built a persistent, in-memory PHP daemon that calculates video durations down to the millisecond, ensuring seamless transitions. Paired with Laravel Reverb (WebSockets), the dashboard reflects live playout states and manual toggles instantly across all administrative screens globally, utilizing surgical TanStack Query cache mutations.
Advanced Media Manager & Importer
We developed a highly intuitive File Manager that allows administrators to effortlessly organize, preview, and manage thousands of video assets using a familiar folder structure and context menus.

Visual Calender & Scheduling View
To make channel programming effortless, we built an interactive Calendar View. Administrators can visually drag, drop, and manage their 24/7 TV schedules days or weeks in advance, getting a clear overview of programming slots and identifying any gaps instantly.


Atomic Downloads & Smart Garbage Collection
Under the hood, we integrated a smart caching layer to prevent race conditions, allowing multiple channels to stream the same file without re-downloading it from S3. To prevent server crashes, our automated self-healing system safely retains media for upcoming schedules and automatically purges orphaned files older than 120 minutes.
