NTT Communications Corporation (NTT Com), the ICT solutions and
international communications business within the NTT (NYSE:NTT) Group,
announced today the details of the IP connection service it provided to
Tokyo Broadcasting System Television, Inc. (TBS), one of Japan’s
nationwide terrestrial broadcasters, for high-quality, low-latency
news—both live and prerecorded—of Japan’s national football team during
the World Cup in Brazil this summer.
Compared to conventional satellite relay systems, the connection service
provided through NTT Com’s Global IP Network realized a
high-performance, cost effective TV broadcasting solution. TBS gave high
marks for the system’s performance, which enabled the company to quickly
convert IP-transmitted data from Brazil into high-quality TV
broadcasting content in Japan.
The Global IP Network’s low-latency connection enabled near-real-time
live conversations with voice delays of less than one second between
people in the TBS TV studio in Japan and the Japanese national team’s
training camp in Brazil, approximately 20,000 km away from Tokyo. In the
case of a conventional Satellite News Gathering (SNG) system, delays are
typically three to four seconds because signals from an on-site location
are sent to a communication satellite and must travel multiple hops in
the signal path, resulting in broadcasts that have something less than a
“real-time” feel.
NTT Com’s IP system also facilitated exceptionally fast transmission of
footage that had been converted into file-based data. The massive files
were used for broadcasts of prerecorded content, such as interviews of
team personnel. TBS was able to transmit the files in 30 to 40 percent
less time than the actual length of the footage, enabling prompt
broadcasting in Japan with minimal delay.
NTT Com, working with its Brazilian subsidiary NTT Comunicacoes do
Brasil Participacoes Ltda. and other partners, established the
high-speed, low-latency relay broadcasting network by combining the
Global IP Network with digital wireless transmission and LAN equipment
of a local carrier.
“NTT Com’s stable Global IP Network connecting the Japanese national
team’s training camp in Brazil and our TBS studio in Tokyo enabled
stress-free broadcasting and data transfer,” said Takayuki Shinaji of
TBS’s Technology Department. “NTT Com comprehensive, one-stop solution,
combining the main connection, return video, communication lines,
internal telephone and all other necessary communications, provided a
highly efficient broadcasting package. Satellite transmissions using SNG
and fly-away technology will remain the standard for now, but our
broadcast of this year’s football event with the capable assistance of
NTT Com has demonstrated the vast potential of global IP transmissions
going forward.”
