Few of the essential difference between MATV, CATV and
IPTV are explained here below:
- MATV (Master Antenna TV). Master Antenna
Television or MATV, describes an analog cabling network which is used to
distribute various television signals throughout a facility. With the
installation of multiple satellite dishes, for centrally subscribing and
distribution of any channel, from any part of the world (both Pay and Free
TV services) can be delivered locally using the technology popularly
termed as SMATV or Satellite Master
- CATV (Cable TV). CATV is nothing but the home-to-home Cable TV
delivery using traditional coaxial cable connection to each of the
residential premises to distribute TV from a central point or head end.
CATV services are more or less irrelevant for large Hospitality
properties, since majority of their clients may not require local
channels.
- Antenna TV system. Thru installing MATV/SMATV capture and
distribution infrastructure (popularly named as ‘headend”), the property
owner provides each room with a Set Top Box (STB) provided by the
broadcaster, which is normally housed centrally at the headend room to
avoid accidental mistuning of channels by the guests. Each channel is
modulated and distributed through the cabling network. Only a TV with
remote is required in each room, and the entire channel array, shall be
displayed locally. The traditional analog headend system used to have
several noise-generating components that affect the signal levels
resulting in distortions in end-user TV signals like ghost images, snow,
etc. Another issue of analog headend used to its limited channel capacity.
While, the maximum theoretical limit is 106 channels, practically, it
never used to exceed 80 channels per system.
- Digital Video Broadcast SMATV. The above indicated
drawbacks have been corrected in MATV systems based on Digital Headend.
Poor signal quality and 80-channel limitations have easily been resolved
by converting the TV signal transmission from analog to digital (DVB).
Using DVB set-top boxes, each channel is converted to digital RF into AV
or HDMI, which is fed directly to the AV or HDMI port of the TV. However,
improper selection and sizing of these headend or its encoders can result
in pixelisation and garbled TV picture. However, There is a significant
cost in converting feed from analog to digital for encoders, QAM’s, etc.
Local CATV services usually beams only local TV channels. Major benefit of
SMATV over CATV is that, you can stream any TV services from any part of
the world to your foreign guests/visitors.
- IPTV (Internet Protocol TV). IPTV is when the
media-to-broadcast content is Ethernet. Using large internet bandwidth,
various broadcasting contents like TV, telephone, signage, video on
demand, high speed internet etc can be delivered to end-user using a
single UTP cable. Also, IPTV is a two-way communication. This means a
hotel guest can communicate to the main hotel server to retrieve
information like on-spot bill, room service ordering, laundering, car
rental bookings, and messaging. The possibilities of IPTV are almost
endless. For eg: Menu cards can be translated into various international
languages, to help the guests know about any dish that they wish to order.
It can be in terms of calorific value, feel and look of a dish,
preparation time and method. Further, centralized Remote management of
set-top box of every room TV is possible. Each set-top box is individually
addressable for any specific guest message or function.
- Importance of IPTV Sizing. Content delivery of
IPTV requires right infrastructure planning. Such infra requires factoring
of various operational requirements such as dissemination of number
channels, services that are to be delivered, level of interactivity etc.
Also, need to consider the convergence requirements of the project; say,
the Data network, high speed internet, telephone services, signage,
conferencing services etc shall share the same media, which will have
tremendous Return of Investment (RoI). Towards this, only enterprise grade
network hardware, having support to advanced streaming protocols are to be
used on the network and are critical to handle the requisite
"speed", "compression", “buffering”, “data processing
thruput”, etc for a quality IPTV/Convergence infrastructure. Setting up of
two parallel networks for IPTV and other IP services is not a good
planning and is not going to be cost-effective.
