How can I find out if my TV tuner will work in Orb?

There are essentially 2 types of TV signal: analog and digital. So TV tuners are either analog or digital. The more recent breed of tuners which are actually dual tuners that combine the two types of TV tuners are generally referred to as hybrid tuners: those are compatible with both analog and digital signal types.

Analog Tuners: Orb primarily supports MPEG-2 analog tuners (NTSC, PAL and Secam), which are tuners with an onboard MPEG-2 hardware encoder.

Software-based analog tuners, which do not have an onboard MPEG-2 hardware encoder, are not supported in Orb. However, many of them can work in Orb when their audio input is properly configured in mycast | Open Application | Control Panel | TV/Webcams | Devices.

Digital Tuners:  Orb only supports over-the-air (OTA) digital ATSC and DVB-T tuners. All other classes of digital tuners (QAM, DVB-S, DVB-C, DVB-H, etc.) are not supported in Orb.

Hybrid Tuners:  The digital tuner (ATSC or DVB-T) of hybrid tuners is supported in Orb;

However, for the analog tuner of hybrid tuners, the MPEG-2 rule applies.

Therefore, the very small form-factor tuner referred to as “USB Hybrid TV Tuner stick” which has a software analog tuner and a digital tuner will only partially work in Orb: digital channels will work, but analog channels won’t.
