Abstract: An interactive multi-player game for two or more users on their mobile devices responding to a live stream video on a separate video streaming device. An interactive video streaming apparatus includes a game server configured to synchronously transmit live stream video data signals and game play data signals via different first and second communication channels, respectively. A video streaming interface transmits the live stream video data signals to a plurality of streaming devices for broadcasting a live stream video. A mobile device interface is configured to transmit the game play data signals to the plurality of mobile devices, separate from the plurality of streaming devices. Accordingly, the mobile device interface is also configured to receive return signals from the mobile devices in response to questions broadcast on the live stream video.

Abstract: A data entry apparatus for e.g. a smart TV comprises a wireless remote control device which is used to navigate a series of cells (19) displayed on screen and containing possible alphanumeric characters at the nth position of a title of e.g. a movie or TV channel. Instead of displaying (say) all 26 letters of the alphabet in these cells, only the possible characters at the nth position of a stored list or dictionary of possible titles are displayed. They are displayed in descending frequency order (most common at the left). The process is repeated (steps S1 to S4) to build up a string of characters in a window (18) until a particular title is selected (YES branch from step S4) by selecting its associated image (20). The navigational effort required of the user is reduced.

Abstract: A user input device comprising a sensor arrangement arranged to detect user interaction with the user input device, and an optical or audio transducer responsive to said sensor arrangement and arranged in use to transmit an optical or audio output signal to an optical or audio sensor of a separate mobile computing device, said output signal encoding instructions for launching or controlling an app.

Abstract: Home purchase of goods or services, including media services delivered via the home user's interactive digital tv or DAB radio (for example the availability of a pay film or participation in a game or competition) may involve use of the purchaser's credit card or the use of a telephone modem installed in the users tv or tv set top box and connected via land line to the public service telephone network, the modem then initiating a call to a premium rate telephone number in order to pay for items purchased. Some people do not have credit cards or may dislike using them for home purchase because of certain security related factors. Meanwhile, not all tv's and set top boxes have telephone modems installed or, if they are installed, they may not be connected. At present, it is rare for modems to be installed in DAB radios.

Abstract: A receiving arrangement for receiving a broadcast programme in interactive fashion comprises a television receiver and a wireless network device such as a WAP-enabled mobile telephone controlled by the recipient of the programee (i.e., the user). The user uses the wireless network device to generate and transmit digital data to the programme broadcaster in interactive fashion. For example, the broadcast programme may be a quiz show and the user may send answers to the quiz questions from the wireless network device. A WAP-enabled Internet site is hosted on a server and is synchronised with the broadcast programme.
