Fox News Channel has been working with Mayfield Heights, OH-based Comet Video to develop PDA-sized video cameras capable of providing broadcast-quality news coverage, Broadcasting & Cable reported on its website Monday. According to the trade publication, Fox became intrigued with the devices after they were demonstrated at the Consumer Electronics Show in Las Vegas last January using the Palm Treo Smartphone. Since then, FNC's director of field operations, Ben Ramos, has been working with Comet to refine the specifications of the unit's transmitters and receivers to raise them to broadcast acceptability.
