MPEG-4 part 10/H.264
The
introduction of advanced video compression (AVC)
encoding, such as MPEG-4/H.264, has the potential to
revolutionize the video industry. With up to 50 percent
bit rate savings compared to MPEG-2, AVC technology is a
compelling choice for service providers looking to roll
out advanced interactive and high-definition television
(HDTV) programming and reduce the cost of delivering
standard- definition programming.
Advanced video compression (AVC)
encoding is one way to get better video quality using
less bits when you perform digital encoding. A 3.75 Mbps
SD stream created using MPEG-2 can be reduced to 1.5
Mbps with equivalent video quality using MPEG-4
compression techniques. The drawback is set-tops have to
be able to decode MPEG-4, so, in the cable space, this
solution is less compelling because all of the existing
set-tops are MPEG-2 only. It does provide an opportunity
to offer expanded tiers of service, thereby offering
MPEG-4 on a demand-based model. This new technology is
especially appealing to the telcos or utilities looking
to get into the video business because they get the
compression benefits and can deploy MPEG-4/Windows Media
9 from the beginning. The long-term solution will
probably be dual MPEG-2/MPEG-4 compatible set-tops.
The Scientific Atlanta Advantage:
The Scientific Atlanta MPEG-4 (Model D9054™/High-Definition)
and (Model D9034™/Standard-Definition)
encoders meet the needs of broadcasters
and cable operators who are looking for ways to deliver
high-performance, high-quality, bandwidth-efficient
video to a marketplace where the need is expanding at an
accelerated pace.
