• Reception of IP streams containing FLUTE/ALC carousels
• support of IP multicast
• extraction and storage of all FDT instances
• extraction and storage of all transmitted files
• display of announced and received data and files
• measurement of carousel cycle time
• calculation of the file transfer bitrate for each carousel
• several simultaneous FLUTE carousel receivers
• useable also for FLUTE file reception in IP based networks
• decoding of XML ESG and announcement files
• archiving of all received files

SAMflute receives IP streams on an UDP socket containing FLUTE/ALC file transfer fragments. The fragments are extracted, the files are rebuilt and saved in the announced directory structure.

Several carousel receivers can be activated simultaneously.

SAMflute is part of the dvbSAM solution. But it can also be used for other purposes, e.g. for FLUTE based file transfer in IP based networks. Therefore the FLUTE receiver can also run on different clients in a distributed environment where the DVB-H frontend sends the services to remote clients.

A seamless interworking between IP Streamer of the SAMcorder and SAMflute is provided. So you can start SAMflute automatically if you activate a DVB-H service transmitting FLUTE carousel files.

For each carousel a detailed monitoring of the file transfer status, the announced and completed files, the amount of data and the time needed to complete a carousel cycle can be displayed.

XML based DVB-H ESG files can be decoded and checked. Therefore syntax errors in ESG files can be found as well.

When a new announcement instance is transmitted the new or updated files are recognized and stored. Furthermore there is the possibility to archive all received files in a separate directory.

SAMflute provides an analysis function on FLUTE packet level. For that it is possible to create a snapshot from up to thousand FLUTE packets which were received.

The FLUTE packet analyzer allows to analyze the received data packages on FLUTE protocol level in detail.
