In a targeted advertising system focused advertisements or alternate content is pre-stored on a handheld device, inserted into a multimedia stream at predefined times and points in the content stream for a predefined interval, otherwise referred to as a spot. A micro-splicer, instantiated on a handheld device, enables alternate content insertion into a content buffer, instead of the multicast original content stream, at available advertisement spots during content viewing. The alternate content for the target audience can be downloaded and stored on a handheld device prior to the arrival of the content stream. The micro-splicer uses metadata, transmitted within the content stream or notified by other means, to identify the correct alternate content and insert it into the correct spot for reproduction on the handheld device. |
