  • Stream conditioning for seamless switching of addressable content across transport multiplex, using local stored content as pre-roll and post-roll buffers; in digital television receivers
    Patent number: 8782728
    Abstract: A system, method and apparatus to enable addressable advertising content delivery in which multiple addressable content streams are sent in a transport multiplex, Addressable Content Channel Multiplex, different from the Primary Channel Multiplex on which the Primary Channel is delivered. The Primary Channel is network stream onto which the addressable content is to be inserted. Seamless switch between the Primary Channel and the addressable content streams on the Addressable Content Channel Multiplex is accomplished by using Receiver stored content as interim buffers to which the switching happens prior to switching to a different transport multiplex. These buffers feed the audio and video decoders with content, during the time it takes for the tuner to switch to a different transport multiplex.
