Abstract: To control advertisement or other media content placement in content, content owners or other interested parties may include ad or media content placement metadata in the content item. Media content placement metadata may provide specifications such as a maximum media content (e.g., ad) duration, media content rating, media content size, payment information, placement location on a screen (i.e., for videos or images) and the like. The media content metadata may be extracted and used to retrieve matching media content such as advertisements for inclusion during play of a corresponding content item.

Abstract: A method and apparatus is configured to generate a first message including a portion of a media stream or a portion of a data file. The method and apparatus also generates a second message including the first message, for sending to one or more addressees. The second message also includes information identifying one or more additional entities other than the one or more addressees from which one or more portions of the media stream or the data file can be obtained.

Abstract: The invention relates to a method where a first address (121) from a first network (185) is obtained to a mobile node (180). Network address translation information is received from a network node (140) to the mobile node (180), the network node (140) being connected to a second network (150). An address mapping is indicated between the first address (121) and a second address (101) to the network node (140), the second address (101) being associated with the second network (150). A session establishment request is obtained. The request comprises instances of the first addresses (121) and third addresses (120). The first addresses (121) are replaced with the second addresses (101) in the request. An address mapping is indicated between the third address (120) and a fourth address (100) to the first network node (140). The session establishment request is sent to a remote network node (190) from the mobile node (180).
