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
- Faster load times
- Reduced memory usage
- Smoother transitions
User Experience
- Instant updates
- Clear schedule display
- Easy navigation
Development
- Maintainable code
- Simple data structure
- Easy to extend
