HD Set Top Box Tuner/Decoder
Quick take
The Thor Fiber HD set top box tuner/decoder is designed to convert digital broadcast-style signals to TVs using HDMI (up to 1080p60) and multiple legacy outputs (component, composite, and analog RF CH 3/4). It is a practical option if you need one box for ATSC over-the-air plus Clear QAM cable-style viewing, with EPG and USB PVR recording. The biggest buying caveat is channel organization, especially for Clear QAM, where manual scanning and managing scrambled channels may take extra time.
Pros and cons
Pros
- Dual-standard tuning support for ATSC and Clear QAM (DVB-C Annex B QAM 64/256).
- Multiple ways to connect to older and newer TVs: HDMI, component (YPbPr), composite (CVBS), and analog RF output on CH 3 or 4.
- USB2.0 PVR for record and playback, plus EPG and favorite lists.
- Auto and manual search options, plus selectable NTSC/PAL analog RF output.
Cons
- Channel discovery and organization can require patience, particularly for cable QAM where channel schedules/list formats may not match newer TVs.
- Scrambled channels may not be automatically handled, so you may need to manage open vs. scrambled entries after scanning.
What buyers think
Buyer-review evidence for this model is limited, but the feedback themes that do appear are practical and use-case driven. One recurring point is that remote command response can feel quick, which matters when you are zapping channels on an older set. Another theme is that Clear QAM usage may involve more manual work after scanning, including slower or less automated handling of scrambled channels and some extra time to organize/naming the channels. There is also mention that the unit runs fairly cool, suggesting it is not prone to obvious overheating during regular use.
What it is and how it works
This is an integrated receiver decoder (IRD) that turns digital RF signals into TV-ready outputs. It targets two common digital input paths:
- Over-the-air: ATSC tuning and decoding.
- Cable-style Clear QAM: DVB-C Annex B Clear QAM, supporting QAM 64/256.
From there, you can choose the output path that matches your TV. If your TV has HDMI, you can run a single HDMI cable. If you are trying to keep an older analog TV in service, the box can also feed legacy connections, including an analog RF output set to channel 3 or 4.
Key features that affect everyday use
Connections for both modern and older TVs
The most practical part of this tuner/decoder is its variety of outputs. You get:
- HDMI output: up to 1080p60.
- Component output (YPbPr): up to 1080i (RCA connectors).
- Composite output (CVBS): RCA connectors for standard-definition TVs.
- Analog RF output: selectable NTSC/PAL and channel 3 or 4.
That makes it useful for mixed setups, like updating a display with HDMI while still having fallback options for older TVs.
EPG, favorites, and scanning
For navigation, it includes an electronic program guide (EPG) plus favorites. It also supports both auto and manual search. In real-world use, the combination of scanning controls and EPG can help you get to usable channel lists faster, but buyers who use Clear QAM may still need time to organize entries after a scan.
USB PVR recording
The box includes USB2.0 PVR for record and playback of TV channels using an external USB storage device (for example, a USB stick). If you want pause-like convenience or scheduled recording without a separate DVR, this feature is one of the main reasons to consider the model.
Specs that matter for buying
- Supported tuning standards: ATSC and Clear QAM (DVB-C Annex B) QAM 64/256.
- Video output capability: HDMI up to 1080p60, plus component and composite, plus analog RF CH 3/4.
- Audio: stereo output mode (USB/PVR and TV viewing use the provided outputs).
- HDMI ports: 1 (single-cable use).
- Compatibility signals: designed for TV connectivity via HDMI/RCA inputs, or analog RF on CH 3/4.
Who should buy it
- Home viewers using over-the-air ATSC who want a single box with modern and legacy TV outputs.
- Cut-cable or QAM cable viewers who have access to Clear QAM signals and want HDMI plus fallback to component/composite or analog RF.
- People maintaining older TVs and need an analog-ready path without replacing every screen.
- Buyers who want simple USB recording with EPG and favorites, without adding a separate DVR.
Who should avoid it (or double-check first)
- If you need full compatibility with your cable provider’s guide data. Clear QAM channel schedule and organization may not match what newer cable-ready televisions expect, so manual scanning and organizing could be part of the setup.
- If your signal includes many scrambled channels. The evidence suggests scrambled entries may not be automatically removed the way some TVs handle after a scan, which can add setup friction.
- If you only need one output format. If you have only HDMI and no legacy backup needs, you may prefer a simpler device purpose-built for HDMI-only setups (depending on what your signal requires).
Pros and cons recap
This tuner/decoder stands out for its flexible output options and dual-standard intent (ATSC plus Clear QAM), along with EPG and USB PVR recording. The main tradeoff is that channel list management can take longer for Clear QAM, including work related to scrambled channel handling and naming/organization after scanning.
Verdict
Choose the HD Set Top Box Tuner/Decoder if you want one box that can feed modern TVs through HDMI, while still supporting older analog sets via component, composite, or analog RF on channel 3/4. It is especially compelling for households that need ATSC plus Clear QAM capability and would like built-in USB recording. If you expect cable-style channel lists to organize themselves like newer televisions, plan for a more manual first-time setup, particularly with Clear QAM.
FAQ
