ABSTRACT:
A replacement pathway in an STB is utilized to determine loss of packets and delivery error during reception of media broadcasts, and to retrieve replacement data from one or more replacement media servers. The retrieval of the replacement data is performed during playback of the received media broadcasts. The communication of media broadcast incorporates delays to accommodate the retrieval of replacement data. Alternatively, received broadcast media streams are buffered to enable retrieval of replacement data and to provide seamless presentation of media content in the media broadcasts. The replacement media server performs access authentication operations during replacement data retrieval. The replacement media server is accessed via markup language, for example, HTML and/or XML, based interfaces and/or dedicated APIs. The replacement media server may deny replacement data based on plurality of service criteria such as acceptance and denial criteria, which may comprise allowable bandwidth and/or error rates.
