Despite added advantage over transmissions, the
high cost of higher digital radio receiver sets seems to be a hurdle in
rolling out digital radio transmissions from different radio stations of
the public broadcaster – All India Radio (AIR), in the state.
Earlier,
the AIR had planned to adopt the international DRM (Digital Radio
Mondiale) standard for digital terrestrial radio transmissions in the
Medium Wave (MW) and Short Wave (SW) bands. While three AIR stations in
Chennai, Delhi and Rajkot have started offering digital transmissions,
33 other AIR stations have been offering digital transmissions through
`simulcast mode’ wherein digital and conventional transmissions are both
done simultaneously.
In Odisha, the idea of digital transmission
was experimented with at AIR Sambalpur by installing a DRM transmitter,
but it is yet to start operations allegedly due to the absence of
digital receiver sets among the listerers, an official from AIR
Sambalpur told Orissa POST. While standard radio sets are available for Rs 250, each digital radio set costs around Rs 15,000.
“We
have already installed DRM transmitters, but are yet to start
operations as receiving sets are an issue. They are costlier compared to
normal radio sets. These sets are best suited for SW and MW
transmissions,” the official said.
According to sources in the
AIR, some other radio stations in the state, such as Jeypore and
Bhawanipatna, are also in line of adding digital transmissions, but in
the ‘simulcast mode’. These systems are based on the digital
transmissions where signals are transmitted digitally and there is
hardly any transmission loss midway. Due to this, transmission to the
listeners’ sets is excellent and the listeners enjoy superb sound
quality in Short Wave as well in Medium Wave transmissions. However,
these norms still continue to elude FM transmissions through DRM
technology.
However, DRM experts say the market for DRM seems
optimistic. “Earlier, very few players were manufacturing DRM receiver
sets in India. The scenario has changed and now more players are coming
into the field. As a result, prices are slated to come down to as low as
Rs 6,000 to Rs 7,000 for each new digital radio set. Now the government
also plans to allow DRM technology for FM transmissions. So they have a
good future,” said Alokesh Gupta, an expert on DRM transmissions from
New Delhi.
Bhubaneswar-based radio expert Subrat Pati said, “Such
transmissions are quite popular in European countries, but we are far
behind in adapting such path-breaking technologies. Pricing is
definitely an issue. If the government subsidises the prices of receiver
sets it can surely proliferate and improve transmission quality to
radio lovers.”
