Digital cable is a type of television service that transmits signals in a digital format, providing clearer picture and sound quality compared to traditional analog cable. It allows viewers to access a wide range of channels, including high-definition (HD) options, and often includes features like on-demand programming and digital video recording (DVR). This service typically requires a cable box to decode the digital signals, which can also offer interactive features such as program guides and parental controls. Many providers bundle digital cable with internet and phone services, creating a comprehensive package for home entertainment and communication.
