Types of STB


1. Cable STB

Cable STBs are designed to receive television signals through cable television networks. They are commonly used by cable TV subscribers to access a wide range of channels and services provided by cable operators. Cable STBs are connected to the cable TV network via a coaxial cable, and they decode and display the digital signals on the connected television set. They often offer features such as on-demand content, interactive services, and the ability to browse and select channels from the cable operator’s lineup.

2. Satellite STB

Satellite STBs are used to receive television signals from satellite broadcasting providers. They are commonly used in areas where cable TV infrastructure is limited or unavailable. Satellite STBs receive signals from satellites in geostationary orbit, allowing users to access a diverse range of channels and services. These STBs are equipped with a satellite dish to receive the signals and a decoder to convert them into a format compatible with the connected TV. Satellite STBs often provide features such as high-definition (HD) and even ultra-high-definition (UHD) content, interactive services, and the ability to record and pause live broadcasts.


IPTV (Internet Protocol Television) STBs are used to receive television signals over IP networks, typically provided by internet service providers (ISPs). These STBs are connected to the internet and receive television content in the form of IP packets. IP TV STBs decode the IP packets and display the content on the connected TV. They often provide features such as video-on-demand (VOD), catch-up TV, interactive applications, and the ability to access streaming services. IP TV STBs offer flexibility in terms of content delivery and often allow users to customize their channel lineup and access online content and services.

Each type of STB caters to specific broadcasting technologies and offers unique features and functionalities. Whether it’s cable, satellite, or IPTV, the choice of STB depends on the availability of broadcasting services in a particular area and the preferences of the user in terms of channels, services, and interactive capabilities.
