Abstract (en)
[origin: WO0145396A1] A method and apparatus for providing peer-to-peer communications between televisions wherein content identifying information is sent from any of the televisions (a sending TV) to any other of the televisions (a receiving TV). The content identifying information is information that identifies content currently watched on the sending television including samples of the currently watched content. In operation, each television is first identified to each other television. The identifying information includes determining whether a given receiving TV may convey content identifying information from each sending TV. In some instances, the receiving TV may only be programmed to convey certain types of content identifying information from the sending TV. The identifying of the television is performed by either the televisions or a mediator that is separate from each of the televisions. The televisions receive a receiving compliance status identifying what content identifying information is conveyed from a given sending TV. The televisions may receive the receiving compliance status from users of the televisions. The televisions first determine whether a given user may program or reprogram the content identifying information that may be conveyed from a given sending TV by requesting identifying information from the user such as a password. When a user does not have a proper password, the television will not allow programming and/or reprogramming the content identifying information a given sending TV may send.
