DVB Object Carousel Generator

The Tektronix Object Carousel Generator provides developers and broadcasters with a powerful, easy to use DVB Digital Storage Media Command and Control (DSM-CC) generator tool for Multimedia Home Platform (MHP) and interactive TV test applications.

The tool provides in-depth real-time and off-line generation of MPEG-2, DVB Transport Streams containing Data Broadcast Protocols including DSM-CC, DVB, MHP and Digital Terrestrial Television (DTT) object Carousels. Carousel Generator lets you fully verify products, system design and performance.

Data Broadcasting Overview

DVB Transport Streams were initially developed as means of delivering compressed audio and video services to an end user from a central service provider via a variety of different third-party delivery networks. Broadcasters realized that the same streams and networks could also be used to provide data services, with a number of different ways being defined in the MPEG-2 specification (ISO13818-6) to carry data, the method depending on the type of application.

Typical examples for data broadcast applications include:

  • Set Top Box (STB) firmware updates to the STB operating system
  • STB Application software downloads, such as games
  • Picture or text data; for example, extended advertising information
  • Extended service information and program guides
  • Proprietary data, such as price lists

Similar to the way in which video and audio services are delivered to end users, data broadcasting allows data to be transmitted to consumers set top boxes using Object and Data Carousels, which contain periodic transmissions of information in a transport stream.

The Tektronix Carousel Generator supports Multimedia Home Platform (MHP) with the inclusion of the Application Information Table (AIT) and Object Carousels (as specified in the MHP standard) viewing.

Shown below is how information carried by object carousels is sub-divided and carried by the transport stream:

  • BIOP messages comprise a message header, a message sub-header and the message body which contains data. The message body may contain complete data objects
  • BIOP messages are broadcast in Modules. A Module is formed from one or more concatenated, complete BIOP messages
  • Each Module is fragmented into one or more DDBs that are in turn transmitted in corresponding DSM-CC Sections
  • Sections are transmitted in packets in the transport stream

Carousel Types

The carousel types supported by the carousel generator are as follows:

  • Object Carousels: DSM-CC, DVB, DTT, MHP
