Content manager 212 may be further configured to provide services to manage TV sessions associated with one or more secondary television receivers, such as secondary television receiver 112, and to provide connection ID management.
Input manager 216 may configure primary television receiver 110 to receive and process user inputs from one or more devices. For example, input manager 216 may receive and process inputs from remote control device 118. In some embodiments, input manager 216 receives predefined commands from remote control device 118. For example, remote control device 118 may include a plurality of buttons, which when pressed by an operator of remote control device 118, cause remote control device 118 to transmit a command with a unique identifier. When input manager 216 receives the unique identifier associated with the command, input manager 216 may cause primary television receiver 110 to execute a predefined function, such as stopping, starting, rewinding, and/or fast-forwarding a currently displayed digital content.
In some embodiments, input manager 216 may receive inputs from multiple remote control devices. For example, remote control device 118 associated with secondary television receiver 112, and another remote control device associated with another secondary television receiver, may both transmit commands to input manager 216. In this example, input manager 216 may determine, based on an identifier associated with each remote control device, for which secondary television receiver, and/or which streaming content, the command is intended.
In some embodiments, input manager 216 receives inputs that do not initially correspond to a predefined command. For example, input manager 216 may receive audio data recorded by remote control device 118. In this example, additional processing may be utilized to determine whether the recorded audio data corresponds to a voice command corresponding to a predefined function of the primary television receiver or some other voice communication requesting information from a remote service, such as a voice assistant or an internet search engine.
In some embodiments, input manager 216 receives a predefined command before receiving recorded audio data from remote control device 118. For example, a user may interact with a button or other input of remote control device 118 prior to issuing a voice command. The user interaction may correspond to a voice command initiation request. Remote control device 118 may capture, record, and/or transmit audio data to input manager 216 in response to receiving the voice command initiation request. In some embodiments, the voice command initiation request is generated by primary television receiver 110 and/or secondary television receiver 112. For example, a user may interact with a user interface (UI) presented by primary television receiver 110 and/or secondary television receiver 112 at a display. Upon interaction with a predefined UI item, such as an icon, a voice command initiation request may be transmitted to remote control device 118 to begin recording and/or transmitting audio data to input manager 216. In some embodiments, the voice command initiation request is transmitted to input manager 216 indicating that audio data is, or soon will be, transmitted to input manager 216. The voice command initiation request may cause remote control device 118 and/or input manager 216 to record and/or process audio data until an indication that the voice command request has been completed.
For example, an additional user interaction with remote control device 118, such as releasing a button, may indicate that the voice command request is complete. As another example, remote control device 118 and/or input manager 216 may detect when the recorded audio data no longer includes audio associated with human voice. In some embodiments, remote control device 118 and/or input manager 216 may determine that the voice command request is complete after detecting the absence of a human voice in the audio data for a predetermined amount of time. For example, remote control device 118 and/or input manager 216 may stop recording and/or processing audio data after one second, two seconds, five seconds, or any other suitable amount of time after detecting that the audio data no longer includes a human voice. In some embodiments, remote control device 118 stops capturing, recording, and/or transmitting audio data in response to a message received from primary television receiver 110 and/or secondary television receiver 112. For example, primary television receiver 110 and/or secondary television receiver 112 may determine that a user has stopped talking. Based on this determination, primary television receiver 110 and/or secondary television receiver 112 may transmit a message to remote control device 118 to stop capturing, recording, and/or transmitting audio data. In some embodiments, voice command server system 103 determines that the user has stopped talking and transmits an indication to primary television receiver 110 and/or secondary television receiver 112 to cause remote control device 118 to stop capturing, recording, and/or transmitting audio data.
In some embodiments, input manager 216 may process the audio data received from remote control device 118 before transmitting it to another process and/or service. For example, input manager 216 may include an audio conversion process configured to convert the audio data into a format suitable for other processes and/or services, such as pulse code modulation (PCM) audio data or adaptive differential pulse-code modulation (ADPCM) audio data.
In some embodiments, input manager 216 provides the audio data to one or more other processes operating on primary television receiver 110. For example, input manager 216 may write the audio data received from remote control device 118 to a storage medium, such as a local memory of primary television receiver 110. In some embodiments, the audio data is written to a circular buffer accessible by the one or more processes operating on primary television receiver 110. Once the audio data is written to the circular buffer, one or more processes may receive an indication that new audio data has been written to the circular buffer and begin to read the audio data from the circular buffer.
Remote data sender 220 may be configured transmit the audio data to secondary television receiver 112.

In some embodiments, remote control device 118 may transmit the voice command initiation request, or an indication of the voice command initiation request, to primary television receiver 110 prior to transmitting the audio data. For example, the voice command initiation request may cause primary television receiver 110 to begin processing the audio data received from remote control device 118. Remote control device 118 may begin transmitting the audio data to primary television receiver as it is received from the operator. In some embodiments, remote control device 118 may also transmit the audio data after all of the audio data has been captured. For example, remote control device 118 may transmit the audio data after receiving an indication that the operator is done speaking. The indication may include receiving an interaction with a button or other input of remote control device 118. Additionally, or alternatively, the indication may correspond with a predefined amount of time in which remote control device 118 no longer detects human speech.
In some embodiments, an input manager, such as input manager 216 as described above, processes the audio data received from remote control device 118 by storing it at a location in memory accessible by other processes operating on primary television receiver 110. For example, the input manager may store the audio data in a buffer, such as a circular or ring buffer. One or more other processes operating on primary television receiver 110 may monitor the status of the buffer and detect that new audio data has been written to the buffer. Upon detecting that new audio data has been written, the one or more other processes may then read the audio data from the buffer for additional processing.
At step 312, primary television receiver 110 forwards the audio data to secondary television receiver 112. Primary television receiver 110 may forward the audio data to secondary television receiver 112 for processing by one or more services that are only compatible with secondary television receiver 112.

Alternatively, or additionally, primary television receiver may transmit the audio data using a wireless connection, such as Wi-Fi.
At step 316, secondary television receiver 112 converts the audio data into voice command data. In some embodiments, the audio data received by secondary television receiver 112 is provided to an audio system, such as audio system 256 as described above, for processing and conversion into voice command data. The audio data may be provided to the audio system via an audio hardware abstraction layer (HAL) interface. The audio HAL interface may enable one or more processes to pass the audio data to a voice assistant as input and receive one or more commands actionable by the one or more processes in response, as further described below.
In some embodiments, the audio system and/or a voice assistant converts the audio data into voice command data. The voice command data may include the same and/or a converted version of the audio data, as well as additional data configured to help voice command server system 103 to process the voice command data and generate an accurate command corresponding to the spoken commands provided by an operator of remote control device 118. The additional data may include identifying information related to secondary television receiver 112, such as a unique identifier, and/or information related to the available functionalities and capabilities provided by secondary television receiver 112.
At step 320, secondary television receiver 112 transmits the voice command data to primary television receiver 110. The audio system and/or the voice assistant may use the same means of communication used to receive the audio data in order to transmit the voice command data to primary television receiver 110. For example, the voice command data may be transmitted using TCP/IP over a wired or wireless connection between secondary television receiver 112 and primary television receiver 110.
At step 324, primary television receiver 110 transmits the voice command data to voice command server system 103. Primary television receiver 110 may transmit the voice command data via a wide area network, such as the Internet. After receiving the voice command data, voice command server system 103 may translate the audio data into textual data corresponding to the language spoken by the operator of remote control device 118. Voice command server system 103 may then interpret the textual data to determine the one or more commands intended by the operator of remote control device 118. For example, the textual data may be interpreted as a request for primary television receiver 110 and/or secondary television receiver 112 to perform one or more actions such as changing a channel or opening a particular software application. As another example, the textual data may be interpreted as a request for real world information accessible by voice command server system 103 such as a weather forecast. In some embodiments, after translating and/or interpreting the voice command data, voice command server system 103 generates a command corresponding to the speech provided by the operator of remote control device 118. For example, the command may include instructions to change to a specific channel or execute a particular software application.
At step 328, primary television receiver 110 receives a command from voice command server system 103. Primary television receiver 110 may determine that the command is in response to voice command data transmitted by primary television receiver 110 to voice command server system 103 on behalf of secondary television receiver 112. In some embodiments, the command includes an indication to which of multiple secondary television receivers the command is intended. Based on the indication, primary television receiver 110 may determine to which of multiple possible secondary television receivers the command will be forwarded.
At step 332, primary television receiver 110 forwards the command to secondary television receiver 112. In some embodiments, primary television receiver 110 receives the command and determines that the command was generated in response to voice command data transmitted by secondary television receiver 112. For example, the command may be received with additional identifying information specifying a unique identifier for the requesting process and/or device. Primary television receiver 110 may then determine that the unique identifier corresponds to secondary television receiver 112 and transmit the command to secondary television receiver 112. The command may be transmitted using any of the communication means discussed above such as via a wireless or wired connection between primary television receiver 110 and secondary television receiver 112.
At step 336, secondary television receiver 112 processes the command. In some embodiments, a voice assistant, such as voice assistant 272 as described above, processes the command. For example, after receiving the command, a communication interface of secondary television receiver 112 may determine that the incoming command was received from voice command server system 103 and should be processed by the voice assistant process. In some embodiments, processing the command comprises controlling an operation of secondary television receiver 112 based on the command. For example, the voice assistant process may interpret the command and transmit instructions to one or more processes executing on secondary television receiver 112 for additional action by a hardware and/or software component of secondary television receiver 112. For example, the command may cause another process executing on secondary television receiver 112 to execute a new software application for display by a television screen communicatively coupled with secondary television receiver 112.
In some embodiments, instructions corresponding to the command are transmitted to a control application, such as control application 240 as described above, executing on secondary television receiver 112. The control application may interpret the instructions as a request to present specific digital content at a television screen communicatively coupled with secondary television receiver 112. For example, the command and/or instructions may correspond to a request to change from one content channel provided by primary television receiver 110 to another content channel provided by primary television receiver 110. As another example, the command may correspond to a request to stream digital content stored in a memory of primary television receiver 110 to secondary television receiver 112.
In some embodiments, the command causes one or more processes operating on secondary television receiver 112 to generate instructions for execution by primary television receiver 110. For example, the command may correspond to a request for primary television receiver 110 to provide one or more services, such as media streaming services, to secondary television receiver 112. Additionally, or alternatively, the command may correspond with a request for primary television receiver 110 to provide one or more services to a display communicatively coupled with primary television receiver 110. In some embodiments, the control application generates a content request based on the command. Continuing with the example command described above including a request to change from one content channel to another content channel, the control application may cause a television manager process, such as television manager 236 as described above, to generate a tuning request. The tuning request may include a request for primary television receiver 110 to tune a television frequency tuner to a specific television channel.
At step 340, secondary television receiver 112 transmits instructions to primary television receiver 110 to provide one or more services to secondary television receiver. After receiving the instructions, primary television receiver 110 may identify one or more processes executing on primary television receiver 110 to execute the instructions. For example, primary television receiver 110 may identify a television frequency tuner configured to tune to one of a plurality of frequencies corresponding to a plurality of television channels to execute instructions associated with a tuning request. As another example, primary television receiver 110 may identify a digital content library configured to stream digital content stored in primary television receiver 110 to execute instructions associated with a content streaming request. While the above examples refer to providing digital content, other instructions may configure primary television receiver to provide other services to secondary television receiver 112, such as providing additional software applications and/or updates for installation by secondary television receiver 112.
At step 344, after determining that the instructions correspond with a request to provide digital content to secondary television receiver 112, primary television receiver 110 retrieves the requested content. In some embodiments, retrieving the content includes tuning a television frequency tuner. For example, in response to a tuning request, primary television receiver 110 may cause a television frequency tuner to tune to a frequency associated with the requested television channel. In some embodiments, retrieving the content includes accessing digital content stored in a memory of primary television receiver 110. For example, in response to a content streaming request, primary television receiver 110 may query a database stored on a hard drive coupled with primary television receiver 110 for the requested digital content.
At step 348, after retrieving the digital content, primary television receiver 110 streams the content to secondary television receiver 112. In some embodiments, the digital content may include a live stream of digital data. For example, the digital content may include a video stream received by a television frequency tuner coupled with a satellite antenna at the frequency associated with a specific television channel. Upon receiving the digital content, secondary television receiver 112 may process the digital data for display at a television screen communicatively coupled with secondary television receiver. In some embodiments, primary television receiver 112 streams the content directly to a display, such as a television coupled with primary television 110.

The audio system may include a combination of hardware and/or software components configured to receive analog and/or digital audio, process the audio, and output digital and/or analog data. The audio system may also use the voice command component to generate instructions that control one or more functions of the secondary television receiver based on the audio data, as described below.
At block 416, the voice command data is transmitted to the primary television receiver. As described above, the primary television receiver may be communicatively coupled to the Internet. The primary television receiver and the secondary television receiver may be connected within a local area network separate from the Internet. In other words, the secondary television receiver may be connected to the Internet via only the primary television receiver. Further, the voice command component may utilize one or more services provided by a server system external to the local area network and/or accessible over the Internet to translate and interpret the voice command data. Accordingly, the voice command component, and/or the secondary television receiver, may utilize the primary television receiver as a router to transmit data to, and receive data from, the Internet.
At block 420, the voice command data is transmitted to a voice processing server. In response to receiving the voice command data, the primary television receiver may determine that the voice command data is addressed to a service and/or system external to the local area network. The primary television receiver may then transmit the voice command data to the external service and/or system via the Internet. The voice processing server may be a commercial service designed to receive voice command data from multiple voice command components and return commands and/or information to the respective voice command components.
At block 424, a command generated based on the voice command data is received at the primary television receiver from the voice processing server. In some embodiments, after receiving the voice command data, the voice processing server may translate the audio data into textual data corresponding to the language spoken by the operator of the voice enabled remote. The voice processing server may then interpret the textual data to identify one or more commands intended by the operator of the voice enabled remote. For example, the textual data may be interpreted as a request for the primary television receiver and/or the secondary television receiver to perform one or more actions such as changing a channel or opening a particular software application. As another example, the textual data may be interpreted as a request for real world information accessible by the voice processing server via the internet. In some embodiments, after translating and/or interpreting the voice command data, the voice processing server generates a command corresponding to the speech provided by the operator of the voice enabled remote. In other words, the command is generated based on the voice command data received by the voice processing server. For example, the command may include instructions to change to a specific channel or execute a particular software application.
At block 428, the command is transmitted to the secondary television receiver. In some embodiments, the voice command component utilizes specific libraries and/or functions to interpret the command generated by the voice processing server. Further, the specific libraries, functions, and/or the voice command component itself, may only be executed on predefined operating systems. For example, the voice command component may be executable by the second operating system of the secondary television receiver while the first operating system of the primary television receiver may not be configured to execute the voice command component. Accordingly, after receiving the command from the voice processing server, the primary television receiver may transmit the command to the secondary television receiver for additional processing by the voice command component.
At block 432, an operation of the secondary television receiver is controlled based on the command. In some embodiments, after receiving the command, the voice command component will interpret the command and generate instructions to control one or more operations of the secondary television receiver. For example, the voice command component may interpret the command and generate instructions specific to the second operating system and/or the available hardware coupled with the secondary television receiver. Alternatively, or additionally, the voice command component may interpret the command and call one or more methods defined by the audio HAL interface. The methods defined by the audio HAL interface may be implemented to control various specific software applications executing on the second operating system of the secondary television receiver. Further, various implementations of the audio HAL interface may interact with a control application, such as control application 240 as described above. For example, the voice command component may interpret a command as a request for the secondary television receiver to launch a specific software application. The voice command component may call a method defined by the audio HAL interface designed to launch software applications. The control application may be configured to implement the method and, when the method is called, the control application will launch the requested software application. As another example, the voice command component may interpret a command as a request to change the display of a digital content presented by a television screen communicatively coupled with the secondary television receiver.
In some embodiments, the commands received by the voice command component cause the secondary television receiver to control one or more operations of the primary television receiver. For example, the voice command component may interpret a command as a request to change from one digital content channel to another digital content channel. The voice command component may then transfer the request to the control application of the secondary television receiver to change the digital content. After receiving the request, the control application may determine that a new request for the digital content channel must be generated and transmitted to the primary television receiver in order for the primary television receiver to begin streaming the new digital content channel to the secondary television receiver.
In some embodiments, the primary television receiver includes a television frequency tuner configured to tune to one of a plurality of frequencies corresponding to a plurality of television channels. For example, the primary television receiver may be communicatively coupled with a satellite antenna configured to receive the plurality of frequencies from a service provider, such as service provider 102 as described above. In this example, a request to change a digital content channel may be interpreted by the control application of the secondary television receiver as a request to tune a television frequency tuner to a television channel. The control application may then cause a television manager component, such as television manager 236 as described above, to generate a tuning request including a request for the television frequency tuner of the primary television receiver to tune to the requested television channel. After generating the request, the control application and/or the television manager component may then transmit the tuning request from the secondary television receiver to the primary television receiver. In response to receiving the request, a television frequency tuner of the primary television receiver may then be tuned to a frequency associated with the television channel. Once the television frequency tuner is done tuning, the primary television receiver may transmit a video stream received by the television frequency tuner at the frequency associated with the television channel to the secondary television receiver for display by a television screen communicatively coupled with the secondary television receiver. The video stream may be received by the primary television receiver from the satellite antenna via a satellite link with the service provider
In some embodiments, the secondary television receiver may not be configured to receive audio data directly from the voice enabled remote control. For example, as illustrated and described in relation to
In some embodiments, the audio data may first be captured by the voice enabled remote control. For example, an operator of the voice enabled remote control may speak into a microphone coupled with the voice enabled remote control. In some embodiments, the voice enabled remote control receives a voice command initiation request and the audio data is captured in response. For example, the voice enabled remote control may include a voice command initiation request button which activates an audio data recording process in response to operator interaction with the button. As another example, the voice enabled remote control may be configured to interpret audio corresponding to a predefined voice command initiation request phrase and begin capturing audio data upon detecting that an operator has spoken the predefined phrase into the voice enabled remote control.
At block 508, a voice command component of the second operating system converts the audio data into voice command data. In some embodiments, the first operating system comprises a voice command component that is executed locally by the secondary television receiver. The voice command component may be the same, or function in a similar manner as, voice assistant 272 as described above. For example, the voice command component may be configured to receive audio data and generate instructions to control one or more functions of the secondary television receiver.
In some embodiments, an audio data listener is initiated by the voice command component. For example, after receiving a voice command initiation request, the voice command component and/or another component executing on the secondary television receiver, may begin reading audio data from a shared memory configured to receive the audio data from the voice enabled remote. As the audio data is read from the shared memory, one or more processes may provide the audio data to the voice command component using an audio hardware abstraction layer (HAL) interface. The audio HAL interface may enable one or more processes executing on the secondary television receiver to provide the audio data as an input and receive instructions as an output.
In some embodiments, the secondary television receiver converts the audio data format before the audio data is converted into voice command data. For example, after receiving the audio data in a first format, the secondary television receiver may convert the audio data in the first format to a second format. After converting the audio data into the second format, the secondary television receiver may then transmit the audio data in the second format to the voice command component. The voice command data may include the same and/or a converted version of the audio data as well as additional data configured to help a voice command server system process the voice command data and generate an accurate command corresponding to the spoken commands provided by an operator of the voice enabled remote. The additional data may include identifying information related to the secondary television receiver, such as a unique identifier and/or information related to the available functionalities and capabilities provided by the secondary television receiver.
The voice command component may be a sub-component of an overall audio system provided by the first operating system. For example, the first operating system may include an audio system, such as audio system 256 as described above. The audio system may include a combination of hardware and/or software components configured to receive analog and/or digital audio, process the audio, and output digital and/or analog data. The audio system may also use the voice command component to generate instructions that control one or more functions of the secondary television receiver based on the audio data, as described below.
At block 512, the voice command data is transmitted to the primary television receiver. The primary television receiver may be the same, or function in a similar manner as, primary television receiver 110 as described above. The second operating system may be the same, or function in a similar manner as, first operating system 204 described above. The primary television receiver may be communicatively coupled to the Internet. The primary television receiver and the secondary television receiver may be connected within a local area network separate from the Internet. In other words, the secondary television receiver may be connected to the Internet via only the primary television receiver. Further, the voice command component may utilize one or more services provided by a server system external to the local area network and/or accessible over the Internet to translate and interpret the voice command data. Accordingly, the voice command component, and/or the secondary television receiver, may utilize the primary television receiver as a router to transmit data to, and receive data from, the Internet.
At block 516, the voice command data is transmitted to a voice processing server. In response to receiving the voice command data, the primary television receiver may determine that the voice command data is addressed to a service and/or system external to the local area network. The primary television receiver may then transmit the voice command data to the external service and/or system via the Internet. The voice processing server may be a commercial service designed to receive voice command data from multiple voice command components across the network and return commands and/or information to the respective voice command components.
At block 520, a command generated based on the voice command data is received at the primary television receiver from the voice processing server. In some embodiments, after receiving the voice command data, the voice processing server may translate the audio data into textual data corresponding to the language spoken by the operator of the voice enabled remote. The voice processing server may then interpret the textual data to identify one or more commands intended by the operator of the voice enabled remote. For example, the textual data may be interpreted as a request for the primary television receiver and/or the secondary television receiver to perform one or more actions such as changing a channel or opening a particular software application. As another example, the textual data may be interpreted as a request for real world information accessible by the voice processing server via the internet. In some embodiments, after translating and/or interpreting the voice command data, the voice processing server generates a command corresponding to the speech provided by the operator of voice enabled remote. In other words, the command is generated based on the voice command data received by the voice processing server. For example, the command may include instructions to change to a specific channel or execute a particular software application.
At block 524, the command is transmitted to the secondary television receiver. In some embodiments, the voice command component utilizes specific libraries and functions to interpret the command generated by the voice processing server. Further, the specific libraries and functions, and/or the voice command component itself, may only be executed on predefined operating systems. For example, the voice command component may be executable by the first operating system of the secondary television receiver while the second operating system of the primary television receiver may not be configured to execute the voice command component. Accordingly, after receiving the command from the voice processing server, the primary television receiver may transmit the command to the secondary television receiver for additional processing by the voice command component.
At block 528, an operation of the secondary television receiver is controlled based on the command. In some embodiments, after receiving the command, the voice command component will interpret the command and generate instructions to control one or more operations of the secondary television receiver. For example, the voice command component may interpret the command and generate instructions specific to the second operating system and/or the available hardware coupled with the secondary television receiver. Alternatively, or additionally, the voice command component may interpret the command and call one or more methods defined by the audio HAL interface. The methods defined by the audio HAL interface may be implemented to control various specific software applications executing on the first operating system of the secondary television receiver. Further, various implementations of the audio HAL interface may interact with a control application, such as control application 240 as described above. For example, the voice command component may interpret a command as a request for the secondary television receiver to launch a specific software application. The voice command component may call a method defined by the audio HAL interface designed to launch software applications. The control application may be configured to implement the method and, when the method is called, the control application will launch the requested software application. As another example, the voice command component may interpret a command as a request to change the display of a digital content presented by a television screen communicatively coupled with the secondary television receiver.
