Cisco TelePresence IP VCR Series

Slow download speed when backing up recordings

Why is the download speed so slow when I back up my recordings on the IP VCR?

Recordings are stored on the IP VCR in the .codian format. If you want to back up your recordings, we recommend that you back them up in the .codian format for two reasons:

  • If you back up your recordings by selecting to download them in the MPEG format it will be a slow process. The reason is that the recordings are transcoded from the .codian format to the MPEG format during the downloading process.
  • The .codian format gives you the complete recorded data and you will therefore get a better quality playback when you re-upload them to your IP VCR

If you are running out of space on your IP VCR and need extra storage, from release 2.0 you might want to consider using an external Network File System (NFS) to increase the amount of storage for recordings. Any IP VCR folder can be configured to link to an NFS location, and recordings stored in this way are visible to the IP VCR (or to multiple IP VCRs) and can be played back and/or streamed. For more information about external storage, refer to the IP VCR's online help.

If you require MPEG files of your recordings, Cisco TelePresence recommends that you download the recordings in the .codian format and then use the Cisco TelePresence VCR Converter available from the web site. Cisco TelePresence VCR Converter gives you greater control over the look of the final MPEG and can include the content channel.
