A method of reducing streaming media associated bandwidth via local channel content

There is an increasing amount of traffic on networks being taken up by streaming media. Recent surveys put peak time network usage at ~50% for Netflix and YouTube alone. ( ). This increase in traffic usage for video is putting a tremendous strain on internet providers. A common scenario when watching streaming content online is to watch content of recent shows via services that can include media that is currently being broadcast or has recently been broadcast. Some services offer live recording capabilities, but these require the user to have already decided to record the content ahead of time and only applies to identical content as the stream.

    A proposed method to alleviate this problem would work by using connected devices such as a television provider box to analyse the content available for regular broadcast and compare it with content streamed and identify content that can be used from the local device rather than streamed. Switching to content being broadcast locally will reduce demand on network usage.

    Under the covers, the method would require that content is tagged with metadata. This metadata describes the content being displayed and matches it to an ID. This can be done at the program level; alternatively a show can be broken down even further into sub components such as adverts being displayed, the title sequence, the credits and other scenes.

    When the user starts to stream content, the device playing the stream (the playback device) will broadcast the IDs of content that is coming up in the stream. Other devices on the network, such as the cable box will read this broadcast and scan its upcoming content via an electronic programme guide (EPG) or similar table of content and identify any streams that it has coming up that match those Ids and

will inform the original device that it has content available and will include the time it

is available....
