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

The Carousel Analyzer was developed to meet the speciﬁc need to analyze and display the content and structure of data broadcasts.

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. ARIB Data Ca 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.

Currently, three syntax checking options are available:

Strict private data length / Message length checking. Object: U-U Object Carousel Disabling this 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 page 89, References.)

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 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

Each window within the workspace can be designated as Docked, Floating, or as an MDI Child.

Docked. When docked, a window will be automatically placed against one of the four sides of the workspace.

For example, selecting Docked > To p will dock the selected window at the top of the workspace.

Floating. Designating a window as ﬂoating allows it to be moved around on the monitor desktop independently of the Carousel Analyzer interface.

For example, selecting Floating will allow the window to be moved anywhere on the desktop:

The Carousel Analyzer provides three types of views as a means of inspectingand analyzing information carried in a transport stream.

Static views:

Static views display information derived from the transport stream when itis opened.

Structure views:

Menu bar Toolbar

View > Bitrate

This structure view charts the bit rate of a set of transport entities (for example, BIOP message, PID, module). The bit rate calculation is a rolling average. For any transport entity the sum of the transport packets that contribute to that entity in each 100 ms time-slice are summed. The average is calculated every 100 ms using the last 10 time-slices (that is, the bit rate is the average over the last second).

In some cases a choice is offered between displaying the bit rate of the selected element or a composite bit rate of the selected element and its subsidiary (nested) elements.

NOTE. In calculating bit rates, Carousel Analyzer returns to the stream ﬁle. For

large ﬁles, the calculation may take an appreciable amount of time.

The y-axis is automatically scaled to accommodate the maximum bit rate. The name of the element from which the bit rate is derived and the related graph are linked by color; a line (of the same color) is displayed to the right of the element name.

If an asset is speciﬁed as a wildcard, the timing will wait for that asset and all child assets that are found in the transport stream. This means that a directory can be speciﬁed as a wildcard asset and any content found underneath it in the transport stre as the boot class, and \images\ as a wildcard directory asset.
