Audio and video streams across the Internet deliver various forms of media content for a variety of purposes, such as entertainment, business, research and development. As with more conventional forms of media content delivery, it may be desirable to insert secondary content, such as personalized advertising, into a primary media content stream. Conventional personalized content delivery systems include media stream switching, in which a primary content stream is switched to a secondary stream to deliver alternative content. Media stream switching is technology dependent and requires starting, stopping and buffering the streams, which may result in undesirable silences or delay during switching. Conventional personalized content delivery systems include altering of a playback or playlist. This, however, requires primary content providers to include the secondary content in the playlist and to have the secondary content available at a content setup stage. |
