Abstract:
1. A method of substituting a primary content being transmitted on a primary channel with a substituted content corresponding to a secondary content being transmitted on a secondary channel, the method comprising: buffering, via a first buffer, the primary content being transmitted on the primary channel; buffering, via a second buffer, the secondary content being transmitted on the secondary channel; detecting, via a highlight detector, an occurrence of a highlight in the secondary content being transmitted on the secondary channel at a same time as the primary content being transmitted on the primary channel; and substituting, via a substituting device, the primary content being transmitted on the primary channel with the substituted content on the primary channel in response to a detection, via the highlight detector, of the occurrence of the highlight occurring in the secondary content being transmitted on the secondary channel at the same time as the primary content being transmitted on the primary channel, wherein the substituted content comprises a summary of the secondary content that includes a selection of program segments of the secondary content already transmitted on the secondary channel, wherein the program segments of the summary of the secondary content are selected from a set of program segments (i) occurring up until a corresponding highlight occurrence in the secondary content and (ii) including the corresponding highlight, wherein the summary of the secondary content further comprises only incremental program summary updates with no duplication of program segments of the secondary content included in a previous summary.
