BS EN 62297-2 is an international standard that discusses the transport methods of triggering messages for broadcast applications.
BS EN 62297-2 specifies how the trigger messages defined in IEC 62297-1 are transmitted. A trigger is defined as information sent from a service provider as part of a data broadcasting transmission that initiates an application in a receiver. Additional information in the trigger message allows filtering or prioritization techniques to be applied to the receiver.
BS EN 62297-2 specifies how trigger messages are broadcast using Teletext technology. Both Page Format-Clear and Independent Data Line methods are defined in BS EN 62297-2, using protocols defined in ETSI EN 300 708.
BS EN 62297-2 on transport methods for broadcast applications is relevant to:
A trigger message defines the trigger event that includes a URL and optional attributes to specify, for example, a countdown timer and an expiration time. Emerging data broadcasting specifications allow a service provider to trigger an application in a TV receiver.
BS EN 62297-2 focuses on the transport methods for the broadcast applications of the trigger messages defined in IEC 62297-1. It includes examples of possible use that include the forcing of the display of information in order to warn of severe weather conditions and advising of extreme content in the TV program. In an interactive system, a message or icon is displayed inviting online access to vote, register an interest in an advertised product, or browse program-related content.
The transport page in accordance with BS EN 62297-2 consists of a packet X/0 (mandatory), some or all packets X/1-X/25, and X/28/0 (mandatory). It addresses the Page Format-Clear protocol, fully defined in ETSI EN 300 708, which is used to transmit one or more trigger messages.
Overall, BS EN 62297-2 is useful as it aids the transport methods for broadcast applications of triggering messages which can be beneficial for your business.
