`“Given the desire to watch various
`World Wide Web media on a family’s
`primary television set, and to control
`this operation from the comfort of
`one's couch, there is a need to operate
`a television set or other display
`remotely from a personal computing
`device, such as a mobile phone.”

`
`“In various implementations, the system
`can
`facilitate
`allowing
`a
`personal
`computing device to be used to select
`different content to be played on a remote
`display even if different media players are
`required to present the different content.
`The system also can allow the user to
`control how the content is displayed on the
`display device using
`the personal
`computing device. For example, user-
`initiated play commands can be passed
`from the user's personal computing device,
`through the server system, to the display
`device.”
