Additional Requirements
Depending upon your particular video network needs, you may have
additional system requirements, such as:
• Streaming media client software, such as Oracle Video Client,
2netFX’s StreamRider, or a web browser equipped with a plug-in
• A video server, such as Oracle Video Server, or 2netFX’s
ThunderCastIP, for playing video on demand or a live feed broadcast
• An MPEG encoder for creating MPEG video
• PCI-based 10BaseT or 100BaseT network adapter
Technology Overview
MPEG-1 and MPEG-2
MPEG, an acronym for Moving Picture Experts Group, refers to a
method of data compression optimized for video and audio data. MPEG
encoders significantly reduce video data file sizes by analyzing the
changes between video frames. This remarkably efficient compression
method allows full-screen/full-motion video, and CD-quality audio to be
stored in a relatively compact file. Once the data has been compressed,
however, it must be decompressed before it can be used.
NetStream 2000TV incorporates specialized hardware to decompress
MPEG data at a very high speed, allowing MPEG streams to play back
at a data transfer rates from 500 Kilobits (Kb) to 15 Megabits (Mb) per
second. MPEG-2 video has a resolution of 720 x 480 in 24-bit (16.8
million) colors at 30 frames per second (fps). MPEG-1 video has a
resolution of 352 x 240 in 24-bit (16.8 million) colors at 30 fps. The
MPEG standard is a fully open digital video standard embraced by the
computer and entertainment communities for both television and
personal computers.
DVD
DVD, an acronym for Digital Versatile (or Video) Disc, is a
revolutionary medium capable of storing up to 18 gigabytes (GB) of data
on a standard CD-size disc – more than enough for a feature-length
MPEG-2 movie on one side of the disc.
