Anniversary of Betamax Decision

January 17, 1984 the US Supreme Court decided the case of Sony Corporation of America et al. v. Universal City Studios, Inc., et al., reaffirming that home use recording is considered fair use, and manufacturers were not liable for contributory infringement.

USB Tuner Support for Vista

VCRadio version 1.9 has been stuck in beta for several months. Here’s why:

We have acquired several USB TV/FM tuners to support this product, and none of them have drivers running under Vista yet! We really don’t want to purchase another USB NTSC/FM tuner if we don’t have to, but it might be necessary to test with Vista. We do have several non-TV tuners working with Vista, but for completeness we wanted to look at TV tuners as well.

Does any other VCRadio user have a USB TV/FM tuner with drivers updated for Vista?

High Def Radio Startup

NPR Morning Edition has a story about a couple starting a business to produce high definition radios and the difficulties encountered bringing it to market.

(Our company looked briefly at venturing into the hardware world by designing our own HD Radio device, but were scared away by threats of a broadcast flag.)

Example FM Tuner Design II

In a previous post we pointed to a design project report for a USB FM tuner . Here is another tuner project, a reference design by a semiconductor company wishing to promote its FM tuner ICs. The application note includes software, firmware, board layout, and parts list.

The reference design kit is available for purchase through Digi-Key. We are not able to link directly to the product page for this item, but search for part number “336-1293-ND”.

We will be able to include support for this tuner in VCRadio if anyone requests.
