Ahead of the arrival of DTT in Brazil in December 2007, the Brazilian TV transmission equipment manufacturer Linear has announced investments of $3 million (€2.24 million) in research and development. The company is offering broadcasters its ISCHIO line, made up of digital transmitters and multiplexers. Responding to demand, Linear is expanding its factory at Santa Rita do Sapucaí, where it produces analogue and digital TV (for the ASTC system) solutions. The products are exported to 40 countries, including the US and several in Latin America.
