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 1−97 for details of all references in this section.)

H 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])

H EN 301 192 Specification for data broadcasting [DVB] (Reference [4])

H ARIB STD - B24 Data Coding and Transmission Specification for Digital

Broadcasting (Reference [11])

H Multimedia Home Platform [DVB] (Reference [12])

A bibliography of DTV standards documentation is given in the Reference
section.

The Carousel Analyzer has been 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
displaying the bit rate, repetition rates, structure, syntax, and semantics of data
items.

Carousel Analyzer - Getting Started

The program view shows the various services in the transport stream and their
associated PIDs and data streams. Object or data (one or two layer) carousels and
U-U or U-N messages such as DSM-CC Download can also be displayed with
options to view associated, sections, carrier modules, or transport packets for
each version as required.

An object carousel in the stream can be viewed by contents as a directory
structure containing the underlying objects such as Java classes, picture, or text
files. If an object is associated with an installed application then a double-click
will launch that program, providing, for example, an easy and quick way to view
the contents of a picture file or read a text file.

The structure of the U-N download messages can be viewed showing the
relationship between DII, modules and blocks. The associated DSI and DII
messages contained in the U-N-Download tables can also be viewed in inter­preted or hex fashion; these indicate where to find and view the BIOPs that
contain a required object in the stream.

The timing relationships between the various components can also be easily
shown because the bit rates or the repetition rates of blocks, modules, objects,
U-N messages or SI tables can be shown together in a single graphical display.

Data Broadcasting Overview

Data Broadcasting allows data to be transmitted in asimilar 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.
ARIB Data Carousels and Object Carousels contain identifiable data objects, 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.

BIOP messages contain 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 Download Data Blocks which are
in turn transmitted in corresponding DSM-CC Sections.

Sections are transmitted in packets in the Transport Stream.

The Carousel Analyzer enables each layer of the protocol stack to be analyzed
and inspected. The following sections provide an overview of how the Carousel
Analyzer can be used to locate messages and packets of interest.

Script Selection And

Manipulation

Scripts are available to the Carousel Analyzer to enable structures to be analyzed
successfully.

If any script is not selected or enabled, the stream will not fail to be analyzed,
but any data normally interpreted by that script would be ignored.

Scripts can only be selected and enabled when no files are open. The option is
not available when a file is open.

Handling Script Files. To open the Analysis Settings dialog box, select Settings
from the Analysis menu.

In the Analysis Settings dialog, the left window shows a tree structure of the test
protocols available. The right window shows the scripts currently allocated to the
test protocol; in the example, the listed scripts are associated with the DVB ­Section protocol. The right window also contains the controls needed to
manipulate the scripts.

Note that across the standards, the scripts are not hierarchical; that is, each DTV
standard must be self-contained in terms of the scripts that it uses.

The currently available script files are listed in the Reference section
(page 1−97).

The following paragraphs describe the available script manipulation activities.
The activities are applied to the currently selected test protocol.

Syntax Checking Options

A number of options are available from the Analysis Settings dialog that allow
strict syntax checking to be enabled and disabled.

If any option is not enabled, the relevant syntax will not fail to be checked, but
will be interpreted more loosely.

Syntax Checking Options can only be selected and enabled when no files are
open. The option is not available when a file is open.

Currently, three syntax checking options are available:

Strict private data length/Message length checking. Object: U-U Object Carousel
Disabling this option allows the privateDataLength field where it exists in the
DSI to be set to zero. The application will calculate it when required, using the
total message length and the position of the private data in the message.
(See reference [2], sections 2 and 7.3.6.)

Strict association tag checking. Object: U-U Object Carousel
The association tag field in the stream_identifier_descriptor is an 8-bit value,
while the same field in an object carousel is a 16-bit value. When comparing
these two values, the MSB of the 16-bit value should be zero. Disabling this
option allows it to take other values.
(See reference [4], 9.3 paragraph 3 and [6], paragraph 4.7.7.3.)

Strict CRC/Checksum checking. Object: DSM-CC Section
section_syntax_indicator and private_indicator fields should be the complement
of each other to determine whether a CRC or checksum is in use. Disabling this
option allows them to be the same and allows the application to work out which
method should be applied.
(See reference [2], section 9.2.2 paragraphs 3 and 4.)

Enabling a Syntax Checking Option. To open the Analysis Settings dialog box
select Settings... from the Analysis menu.

Select the Options tab. The dialog shown below is displayed:

In the Analysis Settings dialog box, the left window shows a tree structure of the
test protocols available. The right window shows the options currently allocated
to the test protocol; note that currently, options are only applicable to DSM-CC
Sections and U-U Object Carousels. Available options are applicable to all
standards, for example, an option set in the DVB DSM-CC Section will be
applied in the MPEG and ARIB protocols.

Opening a Stream File

Any Transport Stream file can be opened for browsing by the Carousel Analyzer.
However, only those streams containing Data and/or Carousel Objects will
provide meaningful results. Tektronix Transport Stream Compliance Analyzer
should be used for normal stream analysis. Only one file can be opened at a time.

To open a file, select File > Open. If the required file is in the list of recently
analyzed files, then it can be opened from the list to save using the open file
dialog box.

Alternatively, use the Ctrl+O keyboard shortcut.

There is a shortcut button available on the Toolbar for opening a file, which uses
the standard file open symbol:

As the file opens, a progress bar is displayed; analysis may require more than
one pass through the transport stream file. The current pass number is shown in
the title line. After the first pass, a second progress bar (new resolved links)
shows the number of unresolved links at each pass.

Analysis can be halted at any time by selecting the Stop button in the dialog
box; the stream is still opened, but only the elements that have been analyzed so
far will be displayed.

By default, the Services window and the Log window open as soon as a stream
file opens. Further windows can be opened by using the View Menu or the
Toolbar. Note that although the options on the View menu remain the same, they
are enabled or disabled according to which protocol element is highlighted at the
time.
