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"
  ]
}
Enter fullscreen mode Exit fullscreen mode

Key Components

  1. Schedule Task 
' GetScheduleTask.brs
Function GetSchedule() as Object
    ' Simplified JSON parsing
    ' Better error handling
    ' Direct string formatting
End Function
Enter fullscreen mode Exit fullscreen mode
  1. Mini EPG Display 
' MiniEPG.brs
Function ShowMiniEPG() as Void
    ' Reduced nested conditionals
    ' Direct display of formatted strings
    ' Robust error handling
End Function
Enter fullscreen mode Exit fullscreen mode

Implementation Benefits

  1. Performance

    • Faster load times
    • Reduced memory usage
    • Smoother transitions

  2. User Experience

    • Instant updates
    • Clear schedule display
    • Easy navigation

  3. Development

    • Maintainable code
    • Simple data structure
    • Easy to extend
