Mobile television was one of the themes of the NAB Show in Las Vegas, where I moderated a session on the subject. The National Association of Broadcasters is backing the ATSC Mobile DTV candidate standard, which will allow broadcasters to add mobile services to their existing transmissions. Extending services to mobile phones, portable media players, laptops and in-vehicle receivers is an entirely logical progression for broadcasters. However, proponents remain convinced that provided they have enough channels, consumers will accept low resolution images. Yet the limited success of mobile television elsewhere suggests that viewers expect mobile television to look like television. That implies at least a standard definition picture. If broadcasters are unable to provide an acceptable television experience to mobile devices, consumers will tend towards other forms of video that can already provide better quality and a more personal programming proposition.
