iSponsorBlockTV is a self-hosted companion service that brings SponsorBlock-style segment skipping to YouTube clients running on TVs/media devices where browser extensions are not available. It runs on your network and controls playback by monitoring/communicating with supported YouTube TV or embedded YouTube clients and applying community-submitted SponsorBlock segments.

Key Features

  • Integrates with the SponsorBlock database to fetch skip segments (e.g., sponsor, intro, outro, self-promo).
  • Designed for TV/media-device YouTube experiences where extensions cannot be installed.
  • Network service that can be run on a server/home lab and paired with supported devices.
  • Configurable skipping behavior by category (skip, mute, or ignore depending on support).
  • Provides setup and configuration guidance via repository documentation.

Use Cases

  • Automatically skip sponsor segments and intros on YouTube watched via Smart TVs or streaming boxes.
  • Household-wide YouTube segment skipping without per-device browser plugins.
  • Centralized configuration for multiple living-room devices on the same network.

Limitations and Considerations

  • Works only with specific supported YouTube TV/device clients and may rely on device control/remote APIs; compatibility varies by platform and app updates.
  • Accuracy depends on SponsorBlock community submissions and segment timing.

It is a practical solution for extending SponsorBlock’s benefits to living-room viewing setups. If you already use SponsorBlock on desktop/mobile, iSponsorBlockTV can complement that by covering TV-based playback with centralized control.
