Features

ChannelUP is packed with features designed for the living room. Here's what you get.

EPG Grid​

The main view is a time-based program guide grid, similar to what you'd find on a Foxtel or Fetch TV box.

  • Multi-day coverage — see what's on now, tonight, and up to 7 days ahead
  • Program details — title, start/end time, synopsis, and genre
  • Genre colour coding — quickly identify movies, sport, news, and more at a glance
  • Current-time indicator — a vertical line shows you exactly where "now" is in the grid
  • Smooth scrolling — navigate through time and channels fluidly with your remote

An alternative card-based view for browsing channels:

  • Program artwork — shows images when available from the guide data
  • Progress bars — see how far through the current program you are
  • Synopsis preview — read what's on without switching away
  • Quick-tune — press Enter on any card to start watching immediately

Live Playback​

Press Enter on any channel to start watching:

  • Fullscreen playback — native video playback on your TV
  • Mini carousel overlay — press Down during playback to browse and switch channels without leaving the stream
  • Buffering indicators — visual feedback while the stream loads
  • Screen keep-alive — prevents your TV from going to sleep during playback

DVB-T Support​

Built specifically for Australian free-to-air television:

  • EIT scanning — the app scans broadcast EIT (Event Information Table) data directly from your antenna signal, providing richer and more current program information than the HDHomeRun cloud guide alone
  • Automatic merging — EIT data is merged with cloud guide data, so you always get the best available information for each channel
  • Web Worker processing — all guide normalisation, EIT merging, and filtering runs in a background thread so the UI stays responsive

DVB Subtitles​

Full subtitle support built into the app:

  • DVB bitmap subtitles — rendered as overlays on the video surface, extracted in real-time by a custom TS demuxer in the service layer
  • Multiple accessibility fonts — choose from standard, Atkinson Hyperlegible, or OpenDyslexic fonts for subtitle display
  • Per-channel preferences — your subtitle track choice is remembered for each channel

Multi-Track Audio​

Switch audio tracks during playback:

  • Language selection — choose between available audio languages on multilingual broadcasts
  • Track switching — switch audio tracks without interrupting playback
  • Persistent preferences — ChannelUP remembers your audio track choice per channel and restores it automatically next time you tune in

Auto-Discovery​

No configuration needed:

  • Automatic detection — ChannelUP finds your HDHomeRun tuner on your network automatically
  • Cloud fallback — if local discovery doesn't work, the app falls back to the HDHomeRun cloud discovery service
  • Cached connection — once discovered, your device details are cached for instant reconnection on next launch

Favourites & Filters​

Organise your channel list:

  • Favourite channels — star the channels you watch most
  • Filter by favourites — show only your favourite channels in the grid or carousel
  • Genre filtering — narrow down to specific categories
  • Sort options — sort channels by number or name

Settings​

Customise ChannelUP to suit your viewing habits:

  • Guide look-ahead — control how many days of guide data to display
  • Subtitle font — choose your preferred accessibility font
  • Channel scope — show all channels or favourites only
  • Screen keep-alive — prevent the TV from sleeping during use
  • View toggle — switch between grid and carousel views

Built-in Diagnostics​

For when things don't go to plan:

  • Debug overlay — access detailed information about signal quality, tuner status, storage usage, and app performance
  • Remote diagnostic submission — optionally send a diagnostic report to our support team with one button press
  • localStorage and db8 stats — see exactly what data the app is storing on your TV
