SAMesg analyses the Electronic Service Guide (ESG) of DVB-H multiplexes in all details.

It supports all relevant standards:

• IPDC / CBMS - incl. raw, gzip and BiM encoding
• OMA BCAST - incl. raw and gzip encoding (BiM encoding is not permitted in BCAST)

SAMesg is interworking with following dvbSAM components:

• SAMager Agent - for automated monitoring purposes
• SAMcorder
• SAMbera

SAMesg processes ESG data either coming directly from an ESG server (e.g. via UDP multicast) or coming de-multiplexed directly out of a DVB-H multiplex. In dvbSAM, SAMcorder performs de-multiplexing and feeding SAMesg with the relevant data extracted from the particular multiplex.

SAMesg provides comprehensive features for in-depth analysis of the Electronic Service Guide (ESG) within DVB-H multiplexes. Furthermore it extracts the content of the ESGs (XMLs, SDPs, images, schedules...) for further processing in other applications.

Key Attributes:

• acts as independent ESG client, thus can be used also standalone
• supports IPDC/CBMS and OMA BCAST standards, incl. all encodings types (raw, gzip, BiM)
• supports UDP unicast and multicast
• automatic creation of all IP listeners according to the ESG content
• supports both bootstrap and bootstrap-less ESG's
• in-depth analysis of all ESG bootstrap files
• automatic recognition of all contained ESG's
• in-depth analysis of all container files of all ESG's simultaneously
• supports single and multiple transport mechanism
• decoding of ESG containers up to the last bit
• stores all ESG content (XML's, SDP's, images, ...) of all ESG's into separate directories
• renders the complete ESG program list
• handles ESG updates automatically
• includes versatile features for performing a permanent real-time monitoring of all ESG's within a multiplex
• performs comprehensive consistency checks, cycle timing monitorings and much more...
• provides comfortable graphical user interface
• capable of unattended operation at 24/7

SAMcorder's Navigation feature can be used to detect the ESG bootstrap in the current multiplex. By double clicking the ESG bootstrap entry in the navigation window, an IP streamer gets created automatically and SAMesg gets started, listening on the identified bootstrap port.

ESG Bootstrap Detection

Now SAMesg receives and analyzes all ESG data belonging to the ESG bootstrap:

SAMesg Bootstrap Analyzer

reception and analysis of all bootstrap files FDT instance access descriptor provider discovery each bootstrap file can be analyzed in all details multiple access descriptors and provider discoveries are supported the access descriptor files can be decoded up to the last bit all announced ESG's get listed in a treeview the type of ESG, IPDC/CBMS or OMA BCAST, gets detected automatically bootstrap updates will be recognized automatically and processed the time of last update gets displayed updates are counted the time and average time of bootstrap completion gets analyzed and displayed the state of the bootstrap as well as all measured times can be monitored via SNMP (using SAMager Agent)

After selecting one (or several) ESG's in the Bootstrap Analyzer window, the selected ESG containers get received and analyzed:

reception and analysis of all container files single and multiple transport mechanism is supported each container file can be analyzed in all details the container files can be decoded up to the last bit extraction of all XML fragments, SDP's and Images all content, XML fragments, SDP's and Images get listed in a treeview container updates will be recognized automatically and processed

the time of last update gets displayed updates are counted the time and average time of ESG completion gets calculated and displayed the state of each ESG as well as all measured parameters can be monitored via SNMP (using SAMager Agent)

Upon successful completion of the ESG processing the ESG program information gets rendered:

Rendered ESG and Program Detail Window

additional content information gets displayed via double click on a program entry ESG information like program names get transmitted to SAMcorder to update the program lists SDP files extracted from the ESG get transmitted to SAMcorder/SAMitor for further processing
