If they build it will you want it? That's the DTV question of the month for Zenith Electronics and Triveni Digital, who are partnering with the Public Broadcasting Service (PBS) to provide technical support for a new interactive television series, Life 360, which had its debut last week.

Last week, Zenith Electronics and NxtWave Communications announced they have finalized their agreement to jointly develop compatible enhancements to the Advanced Television Systems Committee (ATSC) DTV standard. The companies had previously responded separately to the ATSC's "VSB Enhancements" Request for Proposals (RFP).

Last week Broadcom, Genesis Microchip, and Texas Instruments announced the introduction of what they describe as a cross-platform digital interconnect standard for the consumer electronics industry and an extension of the Digital Visual Interface (DVI) version 1.0. The companies say that this new standard encompasses the necessary requirements for a "superior digital interconnect technology" used in a variety of consumer electronics such as DVD players, high definition television, and digital set-top boxes.

In a low-key rollout last week, HDNet, which bills itself as "the world's only all-high definition national television network", went live on DirecTV channel 199 with a broadcast of the Minnesota Twins at Texas Rangers. HDNet, with offices in Dallas and Denver, says that this is the first of 15 Major League Baseball games it intends to air throughout the month.
