It looks like the stumbling transition over to digital television here in the US is about to get a little help from LG, which is planning on showing a new mobile digital TV system called MPH at CES. MPH, or Mobile Pedestrian Handheld, is based on an existing system called vestigial side band, or VSB, and can be retrofitted to existing digital systems, enabling a wide range of services -- even to vehicles traveling at highway speeds. LG says it spent two years and $7.4M developing the tech -- we'd say our TV habit is totally worth it.[Via MocoNews]
