`(image of a Roku Ultra and remote control, via https://www.roku.com/products/roku-ultra).
`
`The Roku Streaming Products contain a receiver. These products use wireless communications to
`communicate with a Roku remote control, which requires either an IR or a wireless receiver. See,
`e.g., https://support.roku.com/article/115013256808-what-type-of-remote-control-does-my-roku-
`streaming-device-use-, UEI_001317.
`
`The Roku Streaming Products contain a transmitter. These products contain circuitry associated with
`a High-Definition Multimedia Interface (“HDMI”) connection to send data via the connection.
`
`See, e.g., UEI_001331 (listing the Roku Express, Roku Express+, Roku Streaming Stick, Roku
`StreamingStick+, Roku Ultra, and Roku TV products as “Connect to TV via” “HDMI”).

`first device via use of the receiver,
`the keystroke indicator having data
`that indicates an input element of the
`third device that has been activated;
`
`format the key code for transmission
`to the second device; and
`
`The Roku Streaming Products generate a key code using a keystroke indicator received from a third
`device (remote control) in communication with the Roku Streaming Player via use of the receiver,
`the keystroke indicator having data that indicates an input element of the third device (remote
`control) that has been activated;
`
`The Roku Streaming Products generate a key code in response to a keystroke indicator signal pressed
`on the Roku remote control.
`
`An example of a generated key code is the code that corresponds to a function of an external device,
`such as volume, power, or switching inputs.
`
`The Roku Streaming Products receive the keystroke indicator from the remote control via use of their
`receiver. The keystroke indicator signal has data indicating that an input element of the remote
`control has been activated. This can be observed by the fact that the Roku Streaming Products will
`respond (or not respond) in different ways based on which button is pressed on the remote control.
`
`The Roku Streaming Products format the key code for transmission to the second device.
`
`The Roku Streaming Products format a key code for transmission to the second device, such as a TV,
`AVR, or soundbar via HDMI CEC.
`
`transmit the formatted key code to
`the second device in a key code
`signal via use of the transmitter;
`
`The Roku Streaming Products transmit the formatted key code to the second device in a key code
`signal via use of the transmitter. They transmit a CEC-formatted key code to a second device, such
`as a TV or audiovisual receiver, via HDMI link.
`
`wherein the generated key code
`comprises a one of a plurality of key
`code data stored in a codeset,
`
`wherein the one of the plurality of
`key code data is selected from the
`codeset as a function of the keystroke
`indicator received from the third
`device,
`
`The generated key code comprises a one of a plurality of key code data stored in a codeset. Each key
`code is one of a plurality of key code data stored in the codeset of CEC data.
`
`The one of the plurality of key code data is selected from the codeset as a function of the keystroke
`indicator received from the third device (remote control).

`The Roku Streaming Products
`
`The Roku Streaming Products will respond (or not respond) based on which button is pressed on the
`remote control, which demonstrates that they are able to select functions (key code data) based on the
`data received from the remote as to which button was pressed..
`
`wherein each of the plurality of key
`code data stored in the codeset
`comprises a series of digital ones
`and/or digital zeros,
`
`The Roku Streaming Products include a plurality of key code data stored in the codeset that
`comprises a series of digital ones and/or digital zeros.
`
`The CEC data transmitted by the Roku Streaming Products is made up of a series of digital ones
`and/or digital zeros.
`
`
`and wherein the codeset further
`comprises time information that
`describes how a digital one and/or a
`digital zero within the selected one of
`the plurality of key code data is to be
`represented in the key code signal to
`be transmitted to the second device.
`
`The codeset further comprises time information that describes how a digital one and/or a digital zero
`within the selected one of the plurality of key code data is to be represented in the key code signal to
`be transmitted to the second device (TV, AVR, soundbar, or any other device the Roku Streaming
`Products can control via CEC).
`
`CEC frames include a start bit and header block prior to the data that comprises time information.
`
`
`
`
`
`2. The first device as recited in claim
`1, wherein the receiver comprises an
`RF receiver.
`
`The Roku Streaming Products include an RF receiver, e.g., a Wi-Fi, Wi-Fi Direct, or Bluetooth
`receiver.1 See, e.g., https://support.roku.com/article/360004786894-why-is-my-roku-enhanced-
`remote-not-controlling-volume-and-power-on-my-tv-, UEI_001327 (“Some Roku Enhanced
`Remotes incorporate both wireless and infrared (IR) technologies to seamlessly control both your
`Roku streaming player and your TV.”).
`
`Wireless signals fall within a radio frequency band (3 KHz and 300 GHz, see, e.g.,
`https://www.rfpage.com/what-are-radio-frequency-bands-and-its-uses/), therefore a receiver for a
`wireless signal is an RF receiver.
`
`
`
`
`
`
`1 Roku Products that only communicate with the remote via IR transmissions and are not capable of communicating via Wi-Fi, Wi-Fi Direct, or
`Bluetooth are not accused of infringing this claim.

`4. The first device as recited in claim
`1, wherein the formatted key code is
`transmitted from the first device to
`the second device via a wired
`connection between the first device
`and the second device.
`
`The Roku Streaming Products transmit a formatted key code to a TV, AVR, or soundbar via a wired

`power off, volume up, and volume
`down functional operation of the
`second device.
`
`The Roku Streaming Products comprising the Roku TV, Roku Ultra, Roku Premiere (2018), and
`Roku Premiere+ (2018) generate key codes that control at least one of a power on, power off, volume
`up, and volume down functional operation of a second device, such as a TV, AVR, or soundbar.
`
`Each of these products is capable of controlling TV and/or volume of a second device via CEC.
