`ABSTRACT
`A system for presenting content includes a display device
`storing a virtual client . A display host is operable to execute
`multiple instances of a browser each of which operates as a
`swappable media player that is operable to retrieve and load
`any of a plurality of different media players needed to play
`specified content . The display host is operable to perform
`operations including receiving from a switchboard server
`system a message indicating that a specified media player is
`to be used to play particular content using a first instance of
`a swappable media player , retrieving and loading the speci
`fied media player from a content provider using the first
`instance of the swappable media player , playing the particu
`lar content in a first session using the specified media player ,
`and causing a presentation of the content to be mirrored onto
`the virtual client residing on the display device .

`
`session is received from the switchboard server system . The
`method includes displaying the unique identifier in the first
`session , and causing the display of the unique identifier to be
`mirrored onto a virtual client residing on the display device .
`The foregoing method can be used , for example , to
`RELATED APPLICATION ( S )
`establish a link between a particular instance of the swap
`pable media player and a particular display device . The
`The present application is a continuation - in - part of U . S .
`unique identifier displayed on the virtual client residing on
`application Ser . No . 13 / 157 , 821 , filed on Jun . 10 , 2011 ,
`which in turn claims the benefit of priority of U . S . Provi
`the display device then can be entered into a computing
`sional Patent Application No . 617477 , 998 , filed on Apr . 21 , 10 device ( e . g . , a mobile phone ) that is to be used to select and
`2011 . The contents of the earlier applications are incorpo
`control the playing of content on the display device .
`rated herein by reference .
`According to another aspect , the method includes receiv
`ing in the display host a message indicating that particular
`BACKGROUND
`15 content is to be played in a first session using a specified
`media player . The specified media player can be retrieved
`Techniques are known to facilitate operating a display
`and loaded , and the particular content can be played in the
`device remotely from a personal computing device , such as
`first session using the specified media player . The method
`a mobile phone , in order to view a video file or other content
`can include causing a presentation of the content to be
`on the display device . For example , U . S . patent application
`Ser . No . 13 / 157 , 821 describes a system in which a server 20 mirrored onto the virtual client residing on the display
`system acts as a single interface that can be used to control
`device . In some implementations , the method includes
`any one of multiple media players ( i . e . , computer software
`receiving in the display host a second message indicating
`applications for playing video or other content ) that may be
`that particular second content is to be played in the first
`needed to play different video or other files on a display
`session using a specified second media player . The specified
`device such as a television screen . As an example , the 25 second media player can be retrieved and loaded , and the
`display device may receive from the server system a mes -
