Types of DVB IPTV gateways

A DVB IPTV gateway is a media streaming device that allows users to view television services and broadcast channels over an Internet Protocol (IP) network. Such devices can convert signal transmissions from Digital Video Broadcasting (DVB) systems and provide access to a variety of Internet Protocol Television (IPTV) content.

Different DVB IPTV gateways are available in the market depending on the transmission system:

• DVB-C2/ATSC

  Ahead DVB-C2 is a digital cable television system defined by the DVB Project for the broadcasting of cable television. The second version, DVB-C2, was published by the Digital Video Broadcasting (DVB) in 2013. DVB-C2 carries compressed digital TV channels that can be received by set-top boxes or compatible televisions. The channels can be recorded or viewed. The system allows multi-channel sound and interactive services. It also enables electronic program guides with information on scheduled programs and channel listings. Compatible receivers can automatically search for programs in a specific frequency range or geographic area. Advance program recording and program time-shifting are possible. The system also supports conditional access for subscriber-based encrypted channels. Televisions and set-top boxes with support for the DVB-C2 receiving system can access these channels.

  ATSC 3.0, the next generation of digital TV broadcasting in the United States, Canada, and Mexico, will use the Advanced Television Systems Committee's (ATSC) transmission technology to deliver television programming on an IP-based platform. This system can deliver 4K ultra-HD video with high dynamic range and multiple views, interactive applications, and improved audio. ATSC 3.0 will use the transmission technology of digital TV compatible with existing equipment but will be improved if future devices support the new system. Viewers will be able to receive ATSC 3.0 broadcasts if they have equipment to decode the signals, and broadcasters will continue to transmit on current digital TV channels until broadcaster decide to switch completely to ATSC 3.0.

• DVB-T/T2

  The digital terrestrial television broadcast transmission system adopted by the international telecommunications union is the DVB-T system. It broadcasts digitally compressed television signals that can be received by related set-top boxes or televisions. DVB-T2 is the second version of this system. The version T2 is more advanced than version T1 and can broadcast television on 2 transmission channels. Both versions T1 and T2 permit the broadcasting of multiple concurrent television channels on a single frequency by digitally compressing the signals. These versions also allow the reception of digitally compressed international television signals on related set-top boxes or compatible televisions. Both T1 and T2 systems can provide interactive services with television programs and conditional access for encrypted channels. The signal can be transmitted on either of two transmission channels, T1 or T2.

• DVB-S/S2

  Satellite Transmission: DVB-S for standard definition, and DVB-S2 for HD and advanced services. Device converts satellite signal to IP for playback on devices. It allows watching TV channels directly from satellite on Internet-enabled devices like computers, tablets, and phones. Can select and view different TV channels from satellite source. Provides access to multiple TV channels from one satellite signal through internet-enabled devices.

Features And Functions Of The DVB IPTV Gateway

Various features and functions make the DVB IPTV gateway an important part of TV streaming. These include;

• IPTV streaming: The main purpose of a DVB IPTV gateway is to convert TV signals from satellite, cable, or terrestrial sources into digital format that can be transmitted over the internet. This allows users to access a wide range of TV channels and content via IPTV services.
• Multicast transmission: DVB gateways usually support multicast transmission, which means that multiple TV channels can be sent simultaneously in a single stream. This is more efficient in using bandwidth and resources and allows requesting different channels simultaneously.
• Electronic program guide (EPG): Many IPTV services provide an electronic program guide (EPG), which is a schedule of TV programs that are currently airing or will be airing soon. EPG allows users to navigate through available channels and find desired content easily.
• Video on demand (VOD): In addition to live TV channels, some IPTV services also offer video-on-demand (VOD) content. This content can be accessed at any time for playback or downloading. VOD includes movies, TV shows, and other video content.
• Time-shifting functions: Some DVB IPTV gateways have time-shifting functions. These functions include pause, rewind, and recording live TV. With these functions, users can watch live TV programs more conveniently.
• High-definition (HD) and ultra-high-definition (UHD) support: Many DVB IPTV gateways support high-definition (HD) and ultra-high-definition (UHD) video resolutions, providing clear and high-quality video playback to meet users' needs for high-quality video content.
• Digital rights management (DRM): DRM is a technology used to protect the copyright of video content. DRM IPTV gateways can help manage and protect the rights and interests of video content copyright, ensuring compliance with related regulations and laws.

Usage scenarios of DVB IPTV Gateway

Both the IP and DVB sources of IPTV Streams can be used by the IPTV gateway to create access-convergent services. The device can be connected to a network of computer systems to enable concurrent streaming for up to 256 clients. Other usage scenarios of a DVB IPTV Gateway are listed below:

• Creating a video-on-demand platform: Video on demand (VoD) is an IPTV service that enables users to select and play video content whenever needed. Access to the VoD library is made possible through the set-top box. So, in a DVB-based system, content is initially stored on the server and then requested by clients through the network using the client-server model.
• In hotels, DVB IPTV can provide information, advertising, or entertainment through interactive television systems. Services offered include video-on-demand, time-shifted television, and further multimedia services.
• Contributing to a live streaming event: Live streaming is transforming how one shares and experiences live events. One can now broadcast, using satellite, television, or camera equipment, which is then encoded, transmitted, and delivered to an audience via the internet. Viewers can then engage with the events through websites or applications using their devices.
• Delivering multimedia content to a wide area network (WAN): A wide area network, or WAN, is a telecommunications network that can be used to connect several computers and devices across a large geographic area. Implicitly, WANs allow communication between users and companies worldwide, serving as a bridge that connects local area networks (LANs) over the internet or private WANs.
• Providing allowing interactive applications: An interactive application, or interactive software, is a program that allows users to engage and interact dynamically with computer-based systems, facilitating content exploration and delivering an engaging experience through the website or installation.

How to choose a DVB IPTV gateway

When choosing a DVB IPTV gateway, there are several factors that should be taken into consideration. Here are some of them.
