The method further includes the steps of identifying a selected TV program by the user; determining a correlation level between the interpreted video and audio content of the selected TV program and the interpreted video and audio content of each of the other TV programs; determining TV programs other than the selected TV program; and building and presenting a mosaic display on a TV display including the selected TV program.

Streaming latency in an internet protocol television (IPTV) system is decreased by providing a separate source of the selected A / V content to the user that is immediately available to the user when the user requests the A / V content, and that can be used until the requested A / V content is received from the service provider. The separate source can be a channel change stream (CCS) channel broadcast or multicast from the service provider to the user or a local user storage containing stored initial segments of the A / V content.

When the user initiates the retrieval of the primary content information item by means of entering a user input into the data processing system, e.g. zapping a digital TV that switches channels upon receipt of the user input, he / she has to wait a noticeable time before the rendering and play-out of the primary content information item actually starts. The length of the delay is predicted, on the basis of which one or more secondary content items are rendered and played out to the user during this delay. The invention can also be used for bridging the waiting time in an online ordering system, when loading a program on a personal computer, and in an IMS-based IPTV network.
