Low-Cost Hybrid Hotel IPTV System Without Overhauling Cable TV

Sep 14, 2026

DIBSYS Hybrid IPTV-CATV Integrated Solution

Overview

With the rapid development of digital technology, IPTV smart TV systems have been widely adopted. However, a large number of aged buildings, existing hotels, hospitals and senior care apartments still operate on traditional coaxial CATV networks.

These legacy systems only support analog or digital TV live streaming, without smart interactive capabilities. They cannot deliver welcome pages, hospital notifications, hotel services, information bulletins and other value-added services.

Challenges of Direct Full-IPTV Upgrade

High renovation cost:

Full IPTV transformation requires new network cables for every room. It may damage interior decoration, involves long construction cycles and heavy investment.

High system migration risk:

Property owners prefer to retain the stable existing CATV live TV service and are unwilling to fully replace the TV system in one go.

DIBSYS Hybrid IPTV-CATV Integrated Solution

DIBSYS Hybrid IPTV-CATV Integrated Solution fully reuses the original coaxial cables and eliminates large-scale rewiring, enabling smooth intelligent upgrading of traditional CATV networks. The front-end system unifies multiple signal sources including satellite TV, terrestrial broadcast, HDMI high-definition media and AV analog audio & video.

Through the iMod Hybrid IPTV Server & CATV Modulator, RF radio frequency signals and IP streaming media signals are output simultaneously. Android+DTT hybrid set-top boxes are deployed at the terminal side. Users can watch stable live TV via the existing coaxial lines, and access smart interactive interfaces to expand hotel services, information release, merchandise push and other value-added applications.

Value Delivered to Customers

Protect existing cabling assets and reduce renovation costs

Reuse the current CATV coaxial RF cables without removing legacy wires. There is no need for full-building network rewiring, which shortens construction time and cuts project costs significantly.

Compatibility of old and new systems for smooth migration

Supports both traditional RF CATV live TV and intelligent IPTV services. Customers do not need a one-time full system replacement to lower transformation risks.

Empower TV terminals and expand value-added services

Break the limitation that traditional CATV can only play live TV. The TV screen can display welcome interfaces, hotel services, shopping and announcements to improve user experience in guest rooms / wards and create new revenue channels.

Unified access and aggregation of multi-type signal sources

Supports unified encoding and aggregation of satellite TV, terrestrial digital TV, HDMI HD video and AV analog SD video, realizing centralized management of all program sources

Flexible deployment and scalable services

The system can connect to the Internet. New services such as video-on-demand, advertisement push and information distribution can be added on demand. Android smart terminals support APP expansion for continuous service iteration.

Core Product Architecture

Signal Acquisition Layer

IRD1518PRO: Tuner to IP Gateway receives satellite and terrestrial signals (ISDB-T/DVB-S2/DVB-T2/

DVB-C), and converts RF programs into IP streams.

ENC3281: HDMI/SDI HD Encoder

receives high-definition signals from media players and encodes them into IP streams.

ENC3181: CVBS/AV SD Encoder supports H.264 encoding of multi-channel analog audio and video.

Core Processing Layer

iMod: Hybrid IPTV Server + CATV Modulator

Aggregates all IP program streams and outputs dual signals. RF signals are delivered to the original coaxial CATV network, while IP streams are sent to the local area network.

Terminal Layer

Android + DTT Hybrid Set-top Box

Receives both coaxial RF TV signals and IP network signals. It supports traditional CATV live TV as well as value-added applications including hotel welcome pages, service menus, shopping and announcements.

FAQ

Q: What is Hybrid IPTV, and how is it different from pure IPTV?

A: Hybrid IPTV carries **DVB broadcast signals** and IP broadband signals simultaneously. - Hybrid: Live TV is transmitted over DVB (coaxial / terrestrial / satellite); VOD, catch‑up, EPG and value‑added services run over IP. Live streams do not consume IP bandwidth, delivering stable performance under massive concurrent viewers. - Pure IPTV: All services (live + VOD) run over IP network. Live TV consumes heavy multicast bandwidth and tends to stutter under high concurrency.

Q: What is a Hybrid IPTV STB? What is the difference between Hybrid STB and regular IPTV box?

A: A Hybrid STB (hybrid set‑top box) integrates a **DVB tuner + Ethernet port**. - It can receive DVB RF signals and Ethernet/Wi‑Fi IP signals at the same time. - Ordinary IPTV boxes only have network ports without DVB demodulation modules and cannot receive RF broadcast channels.

Q: Which DVB standards are supported by Hybrid IPTV?

A: Common standards: DVB‑C (cable coaxial), DVB‑T/T2 (terrestrial). One system can support single or multi‑tuner configurations.

Q: How do DVB broadcast and IP work together?

A: 1. Live audio/video: DVB tuner demodulates RF TS stream for local decoding and playback. 2. EPG, program metadata, timeshift, VOD, authentication and firmware upgrade: interact with backend MPS/middleware server over IP.

Q: Can i use wifi for iptv?

A: Yes ,can use ,but need make sure wifi stable

Q: Do the system affect my internet speed?

A: This system working alone ,dont occupy internet resource.

Q: How many tv can be support?

A: Becase live content send over coaxial cable ,so only few resource need for iptv, can support more than 1000tv.
