Honey, I shrunk the TV

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Theme 1 – Samsung is seen as a hostile, anti‑consumer brand
- “Why would Samsung do this?” Because they are a deeply, deeply consumer hostile brand. Do not buy Samsung consumer products… – roughly
- I’ve regretted nearly every Samsung device I’ve ever purchased… – wildzzz
- It’s back to projectors or industry display TVs for me. – asdfqwertzxcv

Theme 2 – Users recommend alternatives or “dumb” setups
- I have a Sony Bravia… you can basically disable all the Google Home stuff and have it run as a borderline “dumb” TV. – roughly
- My best try is a jailbroken LG OLED. – donkeylazy456
- Get a signage‑targeting system which doesn’t come ‘smart’ with Android… you can rely on longer use and no surveillance. – contingencies
- …back to projectors or industry display TVs. – asdfqwertzxcv

Theme 3 – Frustration with the growing complexity of modern TV tech
- I get that running seven different kinds of cables everywhere was a bit of a faff, but honestly I miss those days now that I have to be an electrical engineer, a computer systems analyst and a network engineer just to have my TV play sounds. – deltarholamda
- I chose this setup to avoid running cables… but here we are unfortunately. – cakehonolulu
- The main, unsolved issue was getting the Samsung remote to also work as the cable box remote… Spent 2 full days working on that, to no avail. – asdfqwertzxcv

Universal CEC & IR Bridge (UCIB)

Summary

  • An open-source hardware adapter paired with a mobile/web app that translates HDMI-CEC commands and IR signals into a unified remote control interface, letting any smartphone or generic remote control Samsung (and other) TVs, soundbars, and set‑top boxes.
  • Core value: eliminates the need for Samsung‑specific proprietary remotes and restores universal control over home‑theater devices.

Details

Key Value
Target Audience Home‑theater enthusiasts, renters, and anyone frustrated with vendor‑locked remotes (especially Samsung)
Core Feature Bidirectional HDMI-CEC passthrough + IR learning/emitting, controllable via iOS/Android app or web UI
Tech Stack ESP32‑S3 (USB‑C/HDMI‑CEC), IR transceiver, FreeRTOS, React Native app, WebSocket backend
Difficulty Medium
Monetization Hobby (open‑source hardware kit, optional paid enclosure)

Notes

  • HN users complained that Samsung remotes won’t act as universal controllers and that setting up HDMI‑CEC is opaque; UCB gives them a simple, vendor‑agnostic solution (see comment: “I actually recall seeing an option on my TV to set up the Samsung remote as a ‘universal’ controller…”).
  • Enables discussion around open standards for device control and could spark community‑driven profiles for specific TV models.

TV Privacy Shield (TPS)

Summary

  • A plug‑and‑play network appliance (or Raspberry Pi image) that sits between a smart TV and the home router, actively blocking known telemetry, microphone/camera endpoints, and disabling smart‑platform services while preserving video‑picture quality.
  • Core value: lets users enjoy high‑end panels (Samsung/LG/TCL) as “dumb” displays without surveillance or forced Google/Samsung accounts.

Details

Key Value
Target Audience Privacy‑conscious consumers, signage‑screen buyers, and anyone wanting a non‑smart TV experience
Core Feature DNS‑based blocklist + deep‑packet inspection to strip telemetry, optional HDMI‑CEC passthrough for power‑on/off, web dashboard for toggling features
Tech Stack Raspberry Pi 4, Pi‑hole + custom eBPF filters, Envoy proxy for HTTP filtering, React dashboard
Difficulty Medium
Monetization Revenue‑ready: $49 one‑time hardware kit + $9/yr premium filter updates

Notes

  • Commenters praised buying signage screens to avoid surveillance (“I can rest easy knowing it's not recording all my household conversations…”) and lamented Samsung’s consumer‑hostile practices; TPS offers a software‑only path to achieve the same privacy goal on existing TVs.
  • Provides a concrete talking point about consumer rights and could inspire further debate on manufacturer data practices.

SyncCast: Low‑Latency Multi‑Device Audio Synchronizer

Summary

  • A cross‑platform audio synchronization daemon that runs on a modest SBC or PC, taking audio from any source (TV HDMI‑ARC, optical, Bluetooth) and distributing it to multiple playback devices (Bluetooth speakers, soundbars, headphones) with sub‑20 ms latency, solving wireless audio lag and sync issues like Q‑Symphony.
  • Core value: delivers seamless, lip‑synced audio across heterogeneous wireless/wired speakers without needing proprietary vendor ecosystems.

Details

Key Value
Target Audience Audiophiles, gamers, home‑theater users dealing with wireless audio lag or mismatched device sync (e.g., Samsung Buds, Q‑Symphony)
Core Feature Audio capture → timestamping → jitter‑buffered multicast to Bluetooth LE Audio, classic BT, and wired outputs via ALSA/PulseAudio
Tech Stack Rust audio server (rodio + hound), Bluetooth LE Audio stack, optional DSP via Rubberband, Linux‑based host (Raspberry Pi 4 or Intel NUC)
Difficulty High
Monetization Hobby (open‑source); optional paid support/premium UI

Notes

  • Users described painful experiences syncing Samsung remote as a cable‑box remote and wrestling with wireless audio (“I spent 2 full days working on that…”, “Q‑Symphony… unsolved issue”). SyncCast directly addresses the need for reliable, low‑latency wireless audio across devices.
  • Could stimulate discussion on open audio standards (LE Audio, AVB) and provide a practical utility for mixed‑ecosystem home theaters.
