Media Audit, Ipsos Plan December Houston Encoder Install

The Media Audit and Ipsos plan to begin installing encoders in Houston stations next month to test their electronic measurement system.
They say the test is critical in introduction of their system, which is competing with the Arbitron Portable People Meter as the radio industry eyes future measurement.
The companies pointed out that their news comes five weeks after Arbitron filed a lawsuit naming the firms for alleged patent infringement.
