Data transfer capacity and video conference quality

Data transfer capacity and video conference quality


For any video conference, sound and video conference sign are compacted to go through phone lines or systems continuously. The nature of sound and video rendering is dictated by the nature of the codec utilized (COdage DECoding programming) through the pressure calculation utilized, just as by the size (or data transfer capacity) of the line utilized in videoconferencing. video conference.

Today there is a great deal of videoconferencing/videoconferencing equipment using 64k ISDN lines that move information at a speed of 128kbits second. At this exchange rate we can plan to decompress a video of 15 outlines/second, yet this picture quality will be extremely normal, since it leaves individuals seem hazy on the screen.

A transmission capacity of 384kbits is commonly viewed as a base for a videoconferencing/videoconference application , for which the subsequent video will have a revive pace of 30 outlines/second, which is extremely right. It is increasingly more typical to see video conferencing/gear working at 768kbits or 1.5Mbits every second, along these lines permitting high goals pictures.

Toward the start of videoconferencing/videoconferencing , the sign pressure/decompression calculations utilized by each videoconferencing/videoconferencing hardware brand were all the time of the “restrictive” type, ie the videoconferencing/videoconferencing gear gave did not work. not with those of another brand. Video conferencing measures are

presently accessible as far as coding, so you should ensure that the videoconferencing/videoconferencing framework you are settling on is in any event good with the H.320, H.261, H.263 norms. also, H.263.

Raid Data Recovery

Raid Data Recovery:Our Raid Engineers are highly qualified in the art of extracting data from a failed Raid Array. Emergency service is available 24/7 by calling 800-432-8291 (Toll Free) or direct for international callers +1 201-261-2312

Procedures: (the full service)

  1. Duplicate as many hard drives as possible.
  2. Determine the Raid failure and formulate a Data Recovery Strategy.
  3. If hard drive failures are detected, recover a mirror image of each failed hard drive.
  4. Determine the hard drive order and the stripe size of the Raid Array.
  5. Attempt to restore the raid adapter with the recovered hard drives.
  6. If the raid adapter cannot be restored, reconstruct the Raid image from the raw hard drives
  7. Return the Repaired Raid to the customer or provide the data on an appropriate destination media.

Other Procedures: (the cut rate service…NOT our method)

  1. Try to force the failed elements back online.
  2. No hard drive duplication.
  3. Attempt a raid rebuild without backup.This procedure can create permanent damage to the Raid Array if the Rebuild fails.
  4. Rely on luck that might work occasionally, but not always.

Raid Data Recovery Services: Raid FailureRaid Servers can fail for a number of reasons:

  • On Raid 5 or Raid 10 server, at least two hard drive elements must fail to take the Raid Array OFFLINE.Most commonly, a first hard drive failure occurs at some point and is unnoticed, ignored or a replacement hard drive has been ordered but is not yet installed.
    A second hard drive (member Raid Element) develops a problem. Even a minor problem such as a few bad sectors can cause the Raid Array to crash
    Thus the reliability of a well maintained Raid 5 system is fairly good.
  • On a Raid 1 Array, just one hard drive malfunction can cause a crash.This is the worst of all Raid configuration. It has 2^N drives probability of failure, so that a 4 250GB hard drive Raid 0 has a 16X greater failure rate than a single 1TB hard drive. Most people don’t even know they have a Raid 0 storage because it’s in a sealed box, when they find out, it’s too late.
  • Raid Controllers can fail.Raid controllers can also fail or lose their configuration settings. Power surges or power failures can cause problems especially if you don’t have a UPS (uninterruptible power supply) or even if you have a UPS, if the battery runs out and you have no automatic shutdown procedure setup.
  • Other Hardware failure.Many other electronic parts in a server can fail but usually can be replaced without affecting the Raid Array. The worst minor defect that I have seen was a 25 cent molex drive power connector, 2 had failed intermittently eventually causing the Raid to crash.
