How does IPTV differ from traditional RF cable delivery in how content is transported?

• A. IPTV uses IP-based streaming over the network, while RF cable uses RF-modulated channels
• B. IPTV uses satellite distribution; RF uses fiber
• C. IPTV encrypts content; RF does not
• D. IPTV uses analog signals; RF uses digital

Answer: (A)

IPTV transports video as digital data packets over an IP network. The content is encoded into streams and delivered using standard networking protocols, so it can ride over Ethernet, the Internet, or private IP networks. This packetized approach supports on‑demand streaming, time‑shifted viewing, and easy integration with other IP services, with a receiver (set‑top box or smart TV) decoding the IP streams using common codecs. Traditional RF cable carries channels as RF-modulated signals on coaxial cable. The headend modulates each channel onto a specific RF carrier, and a tuner at the subscriber’s premises selects the desired channel to reproduce. The transport is not packetized IP data in transit; it’s broadcast as RF signals (digital RF in modern systems, or analog in older ones). So the main difference in transport is IP-based streaming over a network versus RF-modulated channels on coax.
