At school I would smuggle a transistor radio into the playground so we could keep up with the cricket scores. Years later, I bought a pocket-sized portable television for the same purpose, which ran on batteries and had a huge and unwieldy extendable antenna – but still could not deliver a half-decent picture.

Today, you can watch television while out and about thanks to an expanding variety of services on a mobile phone, using digital or analogue capabilities built in to the phone or added via a small device. Recently, however, I have been exploring another option, in the form of a neat little device called the Qualcomm Flo TVPersonal Television – or PTV.
