Cable Ready HD certified
Cable Ready HD certification is used in Finland to notify that the device is officially approved by Finnish cable TV operators to be used in receiving HDTV broadcast signal over cable TV.
HDMI output
If the device includes HDMI output, it can be connected digitally to a HDMI-capable display (for example, most flat-screen TVs).
Integrated Conax card reader
Conax is a form of encryption method used by several European pay-TV operators. Without Conax reader, those channels can't be accessed, as the authentication car provided by pay-TV operator can be read only by Conax reader.
Integrated Teletext
Integrated Teletext allows using Teletext services with the device, whether the connected TV supports Teletext or not.
MHP support
MHP is a unified standard for interactive digital TV services. The standard is mostly used in the Nordic countries.
Number of tuners
If the device includes multiple tuners, it typically allows picture-in-picture functions (and, in case of PVR-capable devices, recording) for two or more channels, even if the channels are physically located in different multiplexes.
RS-232 connector
RS-232 connector is usually used to upgrade device's firmware and can't be normally used to transfer videos from the device to a PC.
