Building a Modern EPG System for Roku with BrightScript
As a Roku developer, one of the biggest challenges I faced while building ToonamiTV was creating a smooth, responsive Electronic Program Guide (EPG). Today, I'll share how I implemented this system using BrightScript and JSON.
The Challenge
Creating an EPG for Roku presents several challenges:
- Real-time updates without impacting performance
- Clean, readable schedule display
- Efficient data management
- Smooth user experience
The Solution
I implemented a simplified JSON-based approach that provides:
- Instant schedule updates
- Minimal memory usage
- Clean code structure
- Better user experience
The Data Structure
{
"current": "7:07 PM Initial D",
"next": "7:35 PM Fighting Spirit",
"later": [
"8:00 PM Fighting Spirit",
"8:24 PM Powerpuff Girls Z"
]
}
Key Components
- Schedule Task
' GetScheduleTask.brs
Function GetSchedule() as Object
' Simplified JSON parsing
' Better error handling
' Direct string formatting
End Function
- Mini EPG Display
' MiniEPG.brs
Function ShowMiniEPG() as Void
' Reduced nested conditionals
' Direct display of formatted strings
' Robust error handling
End Function
Implementation Benefits

Performance

- Reduced memory usage
- Smoother transitions
-
User Experience
- Instant updates
