From NY Times story: Later this week, XM is set to introduce receivers capable of storing up to 30 minutes of any live broadcast to play back at a later time. With a function that works much like the pause control of a digital video recorder, the units will also be able to replay the last 30 minutes of the channel to which the unit was most recently tuned. Both companies also offer models that let users store the names of favorite artists and titles. When one of those is playing on another channel, the receiver beeps to alert the listener. In XM’s case, the unit will also automatically switch to that other station. Next month, Sirius will introduce its Sportster model, designed to complement its introduction of NFL Radio, which is a new talk channel, and several channels to transmit every NFL game. The radio can be programmed to jump automatically to the correct station when one of the user’s favorite teams is playing.
To appeal to investors, XM’s Roady2 can display continuously updated stock quotes across the screen. Sirius plans to introduce a radio with a similar feature. Beginning this fall, XM will offer NavTraffic, giving owners of the Acura RL and the Cadillac CTS the ability to combine XM’s continuously updated traffic information with the car’s navigation system, producing color-coded maps showing traffic delays, allowing drivers to obtain alternate routings.
To make it easier to receive satellite radio in the home, Sirius will introduce a $129 accessory antenna that, mounted on the roof, will transmit a signal through the walls into a secondary unit attached to the receiver. And by the beginning of next year, Sirius will offer a receiver that can download Sirius programming from the Internet for later playback in areas where signals cannot reach.
