Patent ID: 8473978

Claim:
A computer-implemented method comprising: identifying a first list of channels, of a plurality of channels carrying content, determined to not be presenting advertising content; identifying a second list of channels, of the plurality of channels, determined to be presenting advertising content; identifying a third list of channels, of the plurality of channels, for which a conclusive determination cannot be made with respect to whether advertising content is being presented, wherein the identifying comprises: determining a likelihood that respective ones of the identified channels are presenting the advertising content, and associating, based on the determined likelihoods, a first set of the identified third list of channels with a first likelihood threshold and a second set of the identified third list of channels with a second likelihood threshold, wherein the second likelihood threshold corresponds to a greater likelihood relative to the first likelihood threshold; receiving, from a user device or a device associated with the user device, input indicative of a channel navigation operation with respect to the plurality of channels; providing, to the user device and based on the channel navigation operation, the content corresponding to the first list of channels; and providing, to the user device and responsive to user input received for expanding the channel navigation operation to include one or more of the identified third list of channels, the content corresponding to at least one channel of the first set of the identified third list of channels.
