3.3.4. 
HTTP File Delivery over internet 
An alternate method of file delivery from Compel, that does not require a continuous 
satellite connection, is HTTP File Delivery over Internet.  Here, the i6420 is commanded by 
Compel to request a file download from the Compel server using HTTP messages over IP.  If a 
path to the server can be found, and the file is ready to send, then the i6420 may “pull” packets 
of file data by HTTP from Compel, using the WGET utility.  Again, the first packet delivered is 
a “control” packet, and any following packets are used to complete the file.  The file is then 
checksummed, and, if OK, placed in the designated path under /u/user, building new folders as 
necessary. 
The relevant user controls are
1.  COMPEL server IP address 
2.  Compel command (scheduled, over internet, or by satellite) to request HTTP file 
download 
3.  First packet timeout 
4.  File send timeout 
3.3.5. 
Other file creation & delivery mechanisms 
The remaining mechanisms used to either create or place files on the iPump6420 is File 
Recording, FTP placement, or SMB placement.  File recording is a process where an audio 
stream is designated by Program and Language Descriptor, then it is converted into an MPEG 
program stream
 and stored to the i6420 HDD as an mpg file.  The files are recorded at the 
stream rates as they appear in the incoming Transport.  The resulting recorded files are stored 
into /u/user/recorded directory.   
For SMB placement, the user must access the i6420 over a network at the LAN port as if it 
were a Windows share location, giving Windows the \\LAN-ip-address format in the Windows 
Explorer address bar, where ‘LAN-ip-address’ is the IP address of the LAN port.  Then the user 
may PUT the file to the desired location under /u/user.*  Meanwhile, for FTP placement, the 
user, again, access the i6420 at the LAN port.  When accessing from text-based FTP programs, 
the i6420 supplies the user an anonymous FTP login.  Then the user may PUT the file to the 
desired location under /u/user.*  However they are placed, about 15 minutes or less after placing 
files on the iPump6420, the file management database should have located the file, established 
playability, and made them available for selection in the web File Manager and Playlist Builder 
views. 
* Putting the files to /u/user/assets is preferred. 
The relevant indicators are
1.  RECORD LED on during file recordings 
The relevant user controls are
1.  FTP access on/off 
2.  SMB access on/off 
3.  Content access on/off.  Allows access to modify or delete files through web or SMB. 
4.  Start file recording (by Program/Audio LD) for a specified time duration to a 
specified file path and name 
5.  Abort file recording
