RADIO TEXT PLUS OVER DIGITAL VIDEO BROADCAST - HANDHELD

摘要

Provided are apparatuses and methods for transmitting radiotext plus data (e.g., RT+ data) to a mobile terminal. In one example, radiotext plus data is received and transmitted to the mobile terminal in a Digital Video Broadcast - Handheld (DVB-H) data stream. Program or service data corresponding to a program may be encoded on IP and transmitted in audio/video data in a DVB-H data stream and RT+ data corresponding to the program may b transmitted on Internet Protocol (IP). For example, the RT+ data may be converted to Real- Time Transport Protocol (RTP) on a RTP timed text protocol. In another example, a content stream may be received and divided into a program data stream and a corresponding RT+ data stream. The RT+ data stream may be converted to RTP and synchronized with the program data on audio/video data in a DVB-H data stream. The RT+ data may be delivered to a mobile terminal.
