Envivio (NASDAQ:ENVI) will spend much of June on the road, taking its message to ANGA Cable in Germany, NexTV in Argentina and BroadcastAsia in Singapore. Envivio's demonstrations at the shows will include Muse software available on the 4Caster appliance or HP blade servers, which is designed to perform encoding, transcoding, packaging, encryption and publishing. Also on display will be the Halo network media processor, which is designed to protect content, adapt it for final delivery at the edge of the network, and enable features such as multiscreen ad insertion.
