Scientific Atlanta Inc has won contracts to supply five large Japanese companies with private television networks. Nippon Telephone & Telegraph Corp is among the companies that will use the US company’s B-MAC satellite system to establish private business television networks; it includes encoders and decoders for video, audio and data signals. The Japanese firms plan to send signals to Japan’s communications satellite, JC-Sat, scheduled to be launched at the end of the month. Scientific Atlanta has also won a government contract to install a satellite network that will provide data, speech and video communications to around 4,000 sites in Indonesia, in a joint development with a local firm. The company claims the contract, to build a network using very small aperture terminal technology, is valued at $10m and, when completed, will be worth $50m. Scientific Atlanta says it beat bids from NEC, Hughes, Contel and Alcatel SA.
