Pakistan Television
Corporation evolved through black and white to color TV, from microwave to
fibre optic and now on to digital satellite broadcasting services. Due to
rapid development of technologies and changes in the broadcast sphere, the
analogue system is not able to address the challenges of the changing
environment and therefore it was needed to upgrade and modernize it. This
up-gradation/modernization procedure will decrease operational cost and
also explore additional revenue opportunities.
PTV launched a full-scale
satellite broadcasting service in 1991-92. Digital TV satellite
broadcasting was launched in 1999. Digital satellite broadcasting enabled
PTV to offer versatile services that take full advantage of beautiful
sharp pictures, clear sound, and advanced functions. Presently, satellite
broadcasting by Pakistan Television is being carried out via Asia Sat
3S(105.5 E) and Thaicom 3 (78.5 E). In 2002 PTV took a historic step by
placing a digital carrier to provide uplink services to a private news
channel, in the vicinity of the already existing analogue carrier. The
analogue uplink format to Asia Sat 3S was digitalized in June 2003. It is
pertinent to mention here that Thaicom-3 uplink facility is in the digital
format since its installation in 1999.
In 2002 PTV Management
decided to efficiently utilize their 36 MHz satellite capacity on Asia Sat
3S by launching a Multiple Channel Per Carrier (MCPC) Digital Video
Broadcast (DVB) Platform with automated server based playout system called
Program Scheduling System (PSS). Al-Hamdo-Lillah, today is a historic day
for Pakistan Television. For the first time in Pakistan a broadcaster has
installed the most modern technology to offer a versatile service that
takes full advantage of top quality programming. This will not only give
the viewer a better picture and sound quality but also boost the viewer’s
confidence in PTV.
The launch of PTV digital
MCPC & PSS Platforms will enhance PTV’s capability and capacity to launch
new channels. PTV would also be able to use the infrastructure for
strategic and commercial advantages in a competitive market place where
the customer demand is increasing at a rapid pace. This Digital Satellite
TV Platform for broadcasting multiple channels will provide uplink
services for the upcoming private sector TV Channels, licensed by the
Government of Pakistan (PEMRA). Last but not least, all these arrangements
will not affect the Satellite & Terrestrial viewers of Pakistan
Television; no new apparatus will be required to watch PTV. However, this
technology will additionally provide them a bouquet of four PTV Channels
on a single satellite frequency with a single satellite reception
apparatus.
