`system;
`
`Toshiba Devices
`Toshiba provides Blu-ray Players and televisions including, for example, playlist applications
`such as Pandora and/or other similar applications, along with internet radio broadcasts through a
`web browser and/or internet radio applications such as vTuner or other similar applications and
`also provides, for example, the Cloud TV user interface and/or an apps store, which enable the
`devices to receive internet radio broadcasts and playlists (“Toshiba Devices”)1,2. The Toshiba
`Devices are electronic devices comprising a network interface enabling the electronic device to
`receive an Internet radio broadcast and being further adapted to communicatively couple the
`electronic device to a central system.
`
`For example, the Toshiba 39L4300U television provides an interface enabling receipt of an
`internet radio broadcast through a pre-installed web browser, which can stream internet radio
`from, for example, www.shoutcast.com. In addition, the Toshiba Devices include the Cloud TV
`user interface and/or an apps store, which may enable the use of additional applications for
`receiving the Internet radio broadcasts.
`
`For example, the picture below shows the Toshiba Cloud TV user interface and its web browser.
`
`1 The Toshiba 39L4300U television charted herein is representative of the Toshiba Devices. Additional Toshiba Devices are listed, without limitation, at the end
`of this chart.
`2 As demonstrated herein, the accused devices literally infringe the asserted claims. However, to the extent any limitation is not literally met, it is met under the

`“b) a system enabling playback of audio content from a playlist assigned to the electronic device via the central system”
`
`The source code for the Pandora Internet radio client running on the Toshiba Devices is
`not publicly available. However, there is an open source Pandora client called Piano Bar.
`A review of the source code for Piano Bar confirms that the Pandora client enables the
`following sequence of steps:
`
`• User selects a station from a list presented (or creates a new one).
`
`• Client sends station ID to Pandora server.
`
`• Client receives a playlist of songs from the server.
`
`• Client iterates through the playlist, fetching the music data for each
`song using the audio URL, and playing it.
`
`• When playlist is empty, client requests further songs from the server.

`
`Pandora delivers a 128-Kbps stream of music, and it only works with a
`broadband connection. It derives its music license from the DMCA (Digital
`Millennium Copyright Act of 1998) guidelines for streaming Internet radio,
`and the digital rights management (DRM) scheme it employs is notable in
`a few ways. First, Pandora will never play a specific song on demand; if
`you add a song to a station, it will show up eventually, but Pandora can
`only work it in at random. Also, you can only skip 10 songs in an hour –
`this is so you can't just skip to the song you're looking for. The license also
`limits the number of times Pandora can play a particular song or artist in a
`particular time period, and to this effect Pandora stores a list of the songs
`played on your station in your computer's Flash local storage so it knows
`what it has played already.
