What should be ensured when installing an add-on card for digital TV capabilities?

When installing an add-on card for digital TV capabilities, it is crucial to ensure support for coaxial connections. This is because many digital TV signals, especially those associated with cable television, are often transmitted via coaxial cables. A digital TV tuner card typically connects to an external coaxial cable to receive signals directly from the cable service or antenna. Ensuring that the installed card is compatible with coaxial connections guarantees that it can successfully receive the digital signals necessary for proper functionality.

Other considerations, such as whether the system has enough memory or supports the correct video format, are also important for overall system performance and compatibility. However, specifically for digital TV capabilities, the physical connection type is fundamental to receiving and processing the incoming signal from the external source.
