Through May 31, 2009, Envivio’s Mobile Streaming Trade-up Program is offering discounts of up to 35 percent to mobile operators, content aggregators and others who replace their legacy software video encoders with its Envivio 4Caster C4 hardware encoding platform.
The 4Caster C4 provides video compression for all three screens of consumer video from a single platform. In addition, it also delivers Envivio's new mobile TV compression quality enhancements, such as:
- Extreme compression, which improves performance at the low bit rates used for mobile TV through H.264 baseline profile encoding
- Spatio-temporal adaptive rate control
- An enhanced rate distortion optimization algorithm
- New text and edge detection that automatically applies compression specific to the text and graphics to make them more legible on smaller screens.
Testing indicates that extreme compression delivers additional performance improvements of up to 25 percent at the bit rates typically used to deliver DVB-H and 3G, or 3.5G, mobile streaming services.
