Aspects of the subject disclosure may include, for example, receiving, for a selected channel, a first video; processing the first video for rendering on a display being viewed by a user; selecting from among a plurality of channels a subset of channels for which to pre-fetch data, the selecting being according to predictions that each channel of the subset of channels is more likely to be requested by the user than each channel of the plurality of channels that is not part of the subset; prioritizing the subset of channels such that a first channel of the subset of channels has a priority over a second channel of the subset of channels, the first channel being given the priority based upon a prediction that the first channel is more likely to be requested by the user than the second channel; pre-fetching, for the first channel, first data of a first type and second data of a second type; and pre-fetching, for the second channel, third data of the first type without pre-fetching any data of the second type. Other embodiments are disclosed.

Pre-fetching of information to facilitate channel switching

Methods and products for reducing the time required to set-up a call are provided. In particular, new functionality to H.324 is added by allowing the transmission of media to commence after a reduced number of H.245 messages have been exchanged by two calling devices. If two terminals involved in a call are capable of automatic connect renegotiation, one or more predetermined logical channels in the two terminals for transmitting media is selected, a message is sent from one terminal to the other terminal to open the predetermined logical channel, and media transmission between the two terminals is commenced.
