Operation Tips

• All assets that are installed into the server should have backup copies available in the

event of disk corruption. This will allow for an easy restoration of the system.

• StreamPlayerPlus allows the recording of live streams to MPEG-1, MPEG-2 and MPEG-

4 files. Once saved the files can then be installed on the EtherneTV-NXG1 server for

playback. Make sure the “hinting” option is checked when recording MPEG-4 files.

• When recording MPEG-4 and MPEG-2 files using StreamPlayer Plus software, it is

advisable to keep the length of the record to under 50 minutes to facilitate creating

playlists and keep viewing time manageable.

• The controls for MPEG-4 Fast Forward and Rewind are not currently supported;

however, slide bars are supported and provide the same functonality.

• As the disks become full the performance of head seek times diminishes and file

ingestion may fail.

• Do not use spaces in filenames. Use underscores; ie: my_history_class.mp4.

• Apple QuickTime 6.5, containing native MPEG-4 support, is the recommended MAC

desktop player for accessing MPEG-4 files from the EtherneTV VOD NXG. QuickTime

supports the Seek feature (accessed through a slider-bar) for MPEG-4 streams. Make

sure Edit >> Preferences >> QuickTime Preferences >> Streaming Transport option is

set to Automatically determine the best protocol and port ID or “use: UDP, RTSP Port ID

554”.

• Samba is a widely used software package that allows Linux systems to connect to

Microsoft Windows networks and seamlessly share files with Windows host computers

and servers. This is the recommended method of ingesting files into the server’s

database. If you are connected to the Internet click

software package.
