I had an interesting discussion with the John Fountain, VP of Technology
for Cox Business Services in Las Vegas.
-Cox, LV is currently providing IPTV services (MPEG-2 and MPEG-4 over an
Ethernet/Network connection). The service can be received through
RF/Broadband and direct network connections (although the latter is for
businesses, mainly hospitality.)
-Cox,LV can provide a set-top box or DVR to the customer that uses IPTV to
record the media. The IPTV DVR records the MPEG-2 and MPEG-4 streams
directly to a hard drive.
-Cox,LV (Hospitality Group) provides services to hotels where a weeks worth
of media is stored at a local server and STBs in each room access the
media. The media cannot be archived and is automatically deleted. The
media is full VOD. One hotel has 3200 rooms.
-IPTV costs about $2000 per drop while Broadband costs about $300 per drop
for infrastructure and equipment.
-Delivery of IPTV via a fiber node costs roughly $5000 per node (we are
looking to get a fiber node to our campus and deliver via our network.)
-Cox receives programming via Satellite and through dedicated networks, in
both analog and digital, but mainly digital.
-Cox is sending all media to the entire city via a Sonnet Ring to six main
distribution points. The media on the Sonnet Ring is in MPEG-2 with
Standard Definition media at 4.5Mb/s and High Definition media at 19.8
Mb/s. For analog service, the digital media is brought to baseband analog
and modulated. For digital service, the signal is QAM to digital RF
carriers. No transcoding is happening and the customer gets the full bits
provided off the Sonnet Ring.
-In the near future, Cox will be converting to MPEG-4 at a target of around
7 Mb/s for High Def. media.
This all may be well known information but I found it interesting.
