摘要： A particular method may include detecting at a first network device of a video distribution network a fault in transmission of a stream of media data with a media channel. The method also includes, in response to detecting the fault, transmitting a notification that includes fault information corresponding to the detected fault and the stream of media data corresponding to the media channel from the first network device to a second network device of the video distribution network.

摘要： The disclosed subject matter relates to an architecture that can scale content resolution in order to mitigate errors in a provisioned service of a communication network, such as a wireless service or a femtocell service that integrates with DSL or other broadband carriers. The architecture can identify fault conditions relating to e.g., bandwidth oversubscription or symbolization integrity. Based upon such identification, the architecture can alter encoding format codecs of certain types of content in order to reduce their resolution/quality, thereby mitigating bandwidth oversubscription fault conditions or freeing up space (without necessarily increasing bandwidth) to insert additional FEC code.

摘要： A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to monitor spectral characteristics of a target channel, a first channel and a second channel, where the target channel is of a digital terrestrial television system, where the first channel is an upper adjacent channel to the target channel, and where the second channel is a lower adjacent channel to the target channel. The controller is adapted to generate an emission mask based on the monitored spectral characteristics and detect interference between the target channel and at least one of the first and second channels based at least in part on the emission mask. Other embodiments are disclosed.
