Abstract (en)

[origin: WO0008848A1] The invention relates to the generation of a video display which is generated from a broadcast stream of digital data which is received from a remote transmitter. In the transmission system, data representing the first and second video diplays is scaled, combined and encoded at the transmitting location and then is transmitted in the encoded format. Data is received by a receiver which decodes the received data and generates first and second video displays in response to the first and second video display data received. In one embodiment the user of the receiver can then select whether the first and second displays are to be shown in conjunction or not. One display may be selected to show additional information to the viewer which relates to the other display and in one embodiment, one display may include visual signing information for the deaf and which visual signing information relates to the information being displayed on the other display.
