What is BS EN 62455 - Internet protocol (IP) and transport stream (TS) based service access about?
BS EN 62455 focuses on Internet protocol (IP) and transport stream (TS) based service access.
BS EN 62455 specifies the terminal for a service purchase and protection system for digital broadcasts, called the 18Crypt system. BS EN 62455 is applicable in all countries and regions with suitably compliant broadcasting and multimedia distribution systems. Guidelines for compatible broadcast services are given BS EN 62455.
Note: The service purchase and protection functions operate in a pure broadcast environment that may be combined with a bidirectional interactivity channel.
Who is BS EN 62455 - Internet protocol (IP) and transport stream (TS) based service access for?
BS EN 62455 on Internet protocol (IP) and transport stream (TS) based service access is useful for:
- Public transport operators 
- Public transport service providers 
- Organizations involved in public transport operations 
- Transport information systems 
- Network engineers 
Why should you use BS EN 62455 - Internet protocol (IP) and transport stream (TS) based service access?
The broadcast network is a digital transmission technology that only allows for one-way communication from the broadcaster to many devices.
BS EN 62455 specifies general specifications and concepts for the service purchase and protection system, a four-layer model signaling and service and content discovery, and several required tools and technologies in detail. Also, BS EN 62455 assists you with the following broadcast systems for individual supported systems:
- IP data cast over DVB-H systems: IP data cast over DVB-H is an end-to-end broadcast system that enables you to provide any form of digital content and services using IP-based mechanisms that are designed for devices with limited computing capabilities and battery life
- DVB T/C/S systems: DVB T/C/S systems are audio/video data end-to-end broadcast systems that use an MPEG2 transport stream and broadcast over terrestrial, cable, or satellite networks. This will aid in the protection of these broadcasts in a pure broadcast environment
- MPEG2 TS-based IP systems: MPEG2 TS-based IP systems use bi-directional IP networks to deliver MPEG2 transport streams for (broadcast) delivery, which will aid in the purchase and protection of services and content delivered via these networks
- Non-MPEG2 TS-based IP systems: Non-MPEG2 TS-based IP systems use bidirectional IP networks to provide audio/video or other data using IP protocols rather than an MPEG2 transport stream, making it easier to acquire and protect services and content delivered over these networks
Overall, you can use BS EN 62455 for service purchase and protection system, to understand the four-layer model for service protection, to know the end-to-end system and use of broadcast and interactivity channels, the types of systems and devices supported by BS EN 62455 and the difference between service and content protection.
