Carousel Analyzer - Getting started

The Digital Storage Media Command and Control (DSM-CC) protocol was
originally developed to provide a VCR-like control mechanism for program
material del
evolved to encompass a wide variety of applications including data broadcasting
and interactive television. DSM-CC forms a core part of a variety of both closed
and open standards such as the DVB MHP (Multimedia Home Platform) standard
for European Interactive Television.

The following DTV standards are supported: (See page 89, References.)

ISO/IEC 13818-6 Information technology - Generic coding of moving
pictures and associated audio information - Part 6: Extension for Digital
Storage Media Command and Control [MPEG] Reference 2

Broadcasting. Reference 11

The Carousel Analyzer was developed to meet the specific need to analyze and
display the content and structure of data broadcasts. The tool provides a variety of
ways of looking at a transport stream and its contents including displayingthebit
rate, repetition rates, structure, syntax, and semantics of data items.

Data Broadcasting overview

Data Broadcasting allows data to be transmitted in a similar way to the way in
which video and audio services are delivered to end users. Object and Data
Carousels are intended for the periodic transmission of information in a transport
stream. DVB Data Carousels contain modules of data of unspecified content.

for example, JPEG files, text files, and application software. Multimedia Home
Platform (MHP) is also supported because the Application Information Table
(AIT) and Object Carousels (as specified in the MHP standard) can be viewed.

The diagram below shows how information carried by data and object carousels is
subdivided and ultimately carried by the transport stream.
