Choose what to play
Open a title, pick a source, or start a download. Tap Play on TV whenever you are ready to move it.
Pick on iPhone. Play in the room.
With 4789 TV and compatible Kodi receivers, your place, audio choice, and subtitles move with the picture. The iPhone becomes a real remote, then brings playback back when you want it.
Simulated receiver flow · deterministic demo
One title, all the way through.
Casting is part of playback, not a separate app. Start from the same poster, source, or download you were already using.
Choose the room
4789 shows saved and nearby destinations. A first-party receiver can still be found when the router suppresses normal discovery.
Keep control
On 4789 TV and compatible Kodi receivers, scrub, change tracks, search subtitles, switch sources, or pull the film back to iPhone.
The handoff keeps the decisions.
Moving the picture should not reset the way you chose to watch it.
01
Your place
Send a playing title at its current position. Pull it back from the receiver at the same point.
02
Your tracks
Audio and subtitle choices carry across first-party and Kodi-compatible handoffs. First-party receivers also accept subtitle appearance controls.
03
Your next move
Change the source or continue to the next episode from the phone remote without returning to the library.
The right route for each screen.
Every destination has different format and control limits. 4789 keeps those differences visible.
| Destination | What you get | What to know | Status |
|---|---|---|---|
| 4789 TV | Automatic local discovery, the full phone remote, TV-remote sync, track control, subtitle tools, and receiver-aware recovery. | Install the receiver and keep it open on the same Wi-Fi when connecting. | Available |
| Kodi | The same Kodi-compatible remote path for playback, progress, tracks, subtitles, and source control. | Enable Kodi HTTP control and use its matching username and password. | Supported |
| Chromecast | Google's device picker, direct playback for common files, and on-device container remuxing for compatible sources. | Container conversion cannot fix every codec. Some Dolby Vision, DTS, and older video formats require another route. | Supported |
| AirPlay | Apple's route picker and player for directly compatible files. | Files that need conversion use Screen Mirroring or a 4789 TV/Kodi receiver instead. | Supported |
| 4789 for Mac | A first-party receiver at desk scale, including nearby transfer of a downloaded film without a router. | The public Mac build is not available yet. | Coming soon |
Built for how rooms actually behave.
The polished part is not a cast icon. It is what happens after the tap.
Control from either screen
Pause or seek with the TV remote and the iPhone catches up. Use the phone and the receiver reports the same state back.
Subtitles stay close
On 4789 TV and compatible Kodi receivers, choose embedded tracks, search for another subtitle, adjust timing, or turn subtitles off.
Audio fits the room
Choose a profile for TV speakers, ARC, eARC, or an AVR. Direct audio is preserved when the active route supports it; otherwise playback falls back to decoding.
Downloads can leave the phone
Send a downloaded film to 4789 TV or Kodi over the same Wi-Fi or your iPhone hotspot, with byte-range support for seeking.
Advanced preview
One phone can know three rooms.
The 4789/Kodi-compatible path can keep up to three receivers connected, play something different on each, and move a title between them. Chromecast and AirPlay are not part of this multi-TV mode.

Install the current public receiver, open it on the TV, then let 4789 find the room from your iPhone.
