## Abstract

A media switching device includes a computer including a processor programmed to actuate the media switching device to select, based on a first input received from a user, a first media content item from one or more received media content items. The processor is further programmed to transmit a first portion of the first media content item via a first wired connection to a first media display device; and transmit a second portion of the first media content item to a second media display device via a radio frequency transceiver.

## Background
BACKGROUND
Home entertainment systems commonly include multiple media sources such as a set top box, a digital versatile disc (DVD) player, and a game box all connected via a switching device to a stationary display device such as a television or monitor. The switching device typically allows a user to switch between the media sources by inputting a command, e.g., via an interface such as a remote control. The switching device may provide a switched video signal and a switched audio signal to the television. However, in some cases, a user may be using a Bluetooth display device such as Bluetooth headphones to receive a portion (e.g., audio portion) of a media content item. The Bluetooth display device is commonly connected directly to the media source device. Switching from a first media source to a second media source while using the Bluetooth display device may disadvantageously require disconnecting the Bluetooth display device from the first media source and connecting the Bluetooth display device with the second media source, creating work and inconvenience for the user.

DETAILED DESCRIPTION
Exemplary System
A switching device provides a mechanism for switching between different media sources for a Bluetooth display device based on input from a user. Advantageously, therefore, the disclosed system spares the work and inconvenience associated with disconnecting from a first media source device and connecting with a second media source device.
FIG. 1 illustrates a media system 10 including a plurality of media devices 12. The media devices 12 provide media content, and are typically known devices such as a set-top box, a laptop, desktop, tablet computer, digital versatile disc (DVD) player, compact disc (CD) player, game box, etc. The term “media content” as used herein, refers to digital audio and/or video data received in a media device 12. The media content may be received from a media source such as one or more of a cable or satellite television headend, a video streaming service such as generally includes a multimedia web server (or some other computing device), etc.
Accordingly, media content is typically delivered as compressed audio and/or video data. For example, the data may be formatted according to known standards such as MPEG or H.264. MPEG refers to a set of standards generally promulgated by the International Standards Organization/International Electrical Commission Moving Picture Experts Group (MPEG). H.264 refers to a standard promulgated by the International Telecommunications Union (ITU). Accordingly, by way of example and not limitation, media content may be provided to a media device in a format such as the MPEG-1, MPEG-2 or the H.264/MPEG-4 Advanced Video Coating standards (AVC) (H.264 and MPEG-4 at present being consistent). As is known, MPEG and H.264 data include metadata, audio, and video components. Further, media content in the system 10 could alternatively or additionally be provided according to some other standard or standards. For example, media content could be audio data formatted according to standards such as MPEG-2 Audio Layer III (MP3), Advanced Audio Coding (AAC), etc.
The media devices 12 are each connected, via a quad audio/video/Bluetooth switcher 14 (hereinafter quad AVB switcher), to a stationary display device 16, such as a television receiver. It is to be understood that, although referred to herein as a stationary display device 16, the stationary display device may be movable, mobile, etc., and may include a television receiver, a monitor, a desktop computer, a laptop computer, a tablet, a mobile telephone, etc. The stationary display device 16 may include a display 18 for viewing a video portion of the media content received from a selected media device 12.
The system 10 further includes a Bluetooth display device 20 which may receive a portion (e.g., an audio portion) of the media content received from the selected media device 12. The Bluetooth display device 20 may be, e.g., Bluetooth enabled headphones, Bluetooth enabled speakers, etc.
As further shown in FIG. 1, the media system 10 may include a remote control 22 that accepts user input in a known manner to control the quad AVB switcher 14. Based on commands from the remote control 22, the quad AVB switcher 14 may select the media content, provided by one of the media devices 12, for displaying on the stationary display device 16 and the Bluetooth display device 20.
The examples of switching devices below are each described as having four media input devices 12 by way of example, and not limitation. A switching device may be programmed to receive media data from any number of media devices. Further, the examples below are described based on the use of a Bluetooth protocol, as is known. It is expected that other wireless protocols, including future variations on the Bluetooth protocol, and/or other short range radio frequency communications protocols, may also be used, along with a compatible display device 12.
As shown in FIG. 2, a media device 12 may include a media element 24, a computer 26 and a Bluetooth transceiver 28. The media devices 12 provide media content to the stationary display device 16 and to the Bluetooth display device 20, and may be, for example, one or more set top boxes, one or more game boxes, one or more digital versatile disc (DVD) players, etc. The media devices 12 may provide the media content in the form of a video signal and an audio signal, as is known.
The media element 24 can be any one of various known hardware elements that can receive, e.g., from a source outside a customer premises, or generate, e.g., by reading a medium that stores digital data, the media content, and may be, e.g., a connection to a satellite system or cable system for receiving media content, a DVD reader which reads data from DVDs, a compact disc (CD) reader which reads data from CDs, a radio receiver which receivers radio frequency signals and extracts the data content, etc. The media element 24 receives and/or generates media data and may provide the data, e.g., to the computer 26.
The computer 26 includes a memory and a processor, the memory storing program code, i.e., computer-executable instructions, executable by the processor. The computer 26 is communicatively coupled to each of the media element 24 and the Bluetooth transceiver 28. The computer 26 may be programmed to receive media content data from the media element 24, and based on the data, to generate known outputs including Video data (V), audio data (A), Bluetooth data (BTD), and/or audio/Bluetooth data (Audio/BTD).
The video and audio outputs may include respectively a video and audio portion of the media content item, and may be output, e.g., to the quad AVB switcher 14. The Bluetooth data signal may include a portion of the media content item, for example, the audio portion, formatted for transmission by the Bluetooth transceiver 28. The audio/Bluetooth data may include both the audio portion of the media content item, and the Bluetooth data. The outputs may be mixed and/or multiplexed as is known for transmission along a common transmission path, for example a wired or wired-pair connection.
Although the examples herein discuss transmitting the audio outputs, video outputs and audio/BTD outputs from the media device 12 to the quad AVB switcher 14 via wired connections, wireless connections may also be used. For example, the media device 12 may transmit one or more of the audio data (A), video data (V) and audio/BTD data (A/BTD) to the quad AVB switcher 14 via one or more wireless connections, e.g., a WiFi connection according to the Institute of Electrical Engineers' (IEEE) 802.11 standard.
The computer 26 may output one or more of the video data, audio data, Bluetooth data, and audio/Bluetooth data to the quad AVB switcher 14. Additionally or alternatively, the computer 26 may output the Bluetooth data signal to the Bluetooth transceiver 28 included in the media device 12.
The Bluetooth transceiver 28 may include hardware elements, software elements, one or more processors and memory. The Bluetooth transceiver 28 may be programmed to generate a Bluetooth radio frequency (BTRF) output based on the Bluetooth data. The Bluetooth transceiver 28 may further be programmed to transmit the BTRF output, e.g., to the quad AVB switcher 14.
The Bluetooth transceiver 28 is programmed to connect, based on one or more instructions from the computer 26, with a Bluetooth Radio Frequency (RF) Switcher 44 (FIG. 6) which may be included in the quad AVB switcher 14. Connecting with the Bluetooth RF switcher 44 in the context of this disclosure means establishing a communications channel between the Bluetooth transceiver 28 and the Bluetooth RF switcher 44 according to Bluetooth protocol, as is known.
Referring back to FIG. 1, the quad AVB switcher 14 generally receives video, audio and Bluetooth formatted data (digital or RF) from one or more media devices 12. The quad AVB switcher 14 further receives user commands, e.g., from a remote control 22, and based on the user commands, selects media content from one of the media input devices 12 for transmission to the stationary display device 16 and Bluetooth display device 20. The quad AVB switcher 14 transmits via a wired or wireless connection a video signal to the stationary display device 16 and further transmits a Bluetooth signal including an audio signal to the Bluetooth headphones 20.

Based on the user input, the computer 56 may instruct the Bluetooth RF switcher 44 to generate the Bluetooth data output based on the BTRF3. The Bluetooth RF switcher 44 may output the Bluetooth data output to the Bluetooth transceiver 35. The Bluetooth transceiver 35 may generate based on the Bluetooth data output, a Bluetooth radio frequency output (Bluetooth Out) and transmit the Bluetooth radio frequency output to, e.g., the Bluetooth display device 20.
Example Process
FIG. 8 is a diagram of an exemplary process 800 to switch between media sources 12 for a stationary display device 16 and a Bluetooth display device 20 based on input from a user. The process 800 starts with a block 805.
In the block 805, a computer 38 associated with a quad AVB switcher 14 detects a turn-on event. The turn-on event may be, for example, an indication from a stationary display device 16 (e.g., a television) that the stationary display device 16 has been turned on by the user. As another example, the turn-on event may be an input from the user, for example, via a remote control 22, that the user is turning-on the quad AVB switcher 14, or selecting a media source 12 via the quad AVB switcher 14, etc. Upon detecting a turn-on event by the computer 38, the process 800 continues in a block 810.
In the block 810, the computer 38 of the quad AVB switcher 14 may search for the presence of an active Bluetooth display device 20 such as a set of Bluetooth enabled headphones. For example, the computer 38 may send, via a Bluetooth transceiver 35 in the quad AVB switcher 14, one or more transmissions indicating that the transceiver 35 is available for connecting with a Bluetooth display device 20. A Bluetooth transceiver in the Bluetooth display device 20 may receive the transmission from the quad AVB switcher 14 and respond. The Bluetooth transceiver 35 in the quad AVB switcher 14 may receive the response, and indicate to the computer 38 that the Bluetooth display device 20 is available. In the case that an active Bluetooth display device 20 is detected, the process 800 continues in a block 815. In the case that no active Bluetooth display 20 is detected, the process 800 continues in a block 820.
In the block 815, the Bluetooth transceiver 35 in the quad AVB switcher 14 establishes a communications channel with the Bluetooth transceiver in the Bluetooth display device 20 according to Bluetooth protocol as is known. The process continues in a block 820.
In the block 820, which may follow from the block 810 or the block 815, the computer 38 of the quad AVB switcher 14 receives user input and/or retrieves data stored in memory indicating a selection of a media source 12. For example, upon detecting a turn-on event, as described in the block 805 above, the computer 38 may retrieve data from memory indicating the most recent media source 12 used to provide media content, or indicating a default media source 12 to provide media content. As another example, the turn-on event may be an input from a user indicating a media source 12 selection. Upon receiving/retrieving the media source selection data by the computer 38, the process 800 continues in a block 825.
In the block 825, the computer 38 selects a media input item for transmission to a stationary display device 16, and when activated, a Bluetooth display device 20. As described above, the computer 38 may send an instruction to a video switcher 30. Based on the instruction, the video switcher 30 generates a video output, which includes a selected one of the video inputs V1-V4.
Similarly, also as described above, the computer 38 may send an instruction to an audio switcher 32, 33 which may generate an audio output, including a selected one of the audio inputs A1-A4.
Additionally or alternatively, in the case that an active Bluetooth display device is detected as described with respect block 810 above, the quad AVB switcher 14 may generate a Bluetooth output including a media input item. The media input item may be an audio input A1-A4, a Bluetooth data input BTD1-BTD4, or a Bluetooth radio frequency input BTRF1-BTRF4.
Referring to FIG. 3, the quad AVB switcher 14a may include a Bluetooth switcher 34 which receives the media input items BTD1-BTD4 as inputs. Based on an instruction from the computer 38, it may generate a Bluetooth data output signal including one of the media input items BTD1-BTD4 and output the Bluetooth data output signal to the Bluetooth transceiver 35.
Referring to FIG. 5, the quad AVB switcher 14c may include the audio switcher 33. The audio switcher 33 may generate, based on an instruction from the computer 38, a Bluetooth data output signal including one of the media input items A1-A4 and output the Bluetooth data output signal to the Bluetooth transceiver 35.
Referring to FIG. 6, the quad AVB switcher 14d may include the Bluetooth radio frequency (RF) switcher 44. The Bluetooth RF switcher 44 may generate, based on an instruction from the computer 38, a Bluetooth data output signal including one of the media input items BTRF1-BTRF4 and output the Bluetooth data output signal to the Bluetooth transceiver 35.
Upon generation of one or more of the video output, the audio output, and the Bluetooth data output, the process 800 continues in a block 830.
In the block 830, the computer 38 of the quad AVB switcher 14 outputs one or more of the video output, the audio output and the Bluetooth output. The video output may be output, for example, via the video switcher 30 through a wired or wireless connection to the stationary display device 16. The audio output may similarly be output via the audio switcher 32, 33 through a wired or wireless connection to the stationary display device 16.
The Bluetooth data output signal may be converted to a Bluetooth radio frequency signal (Bluetooth Out) and transmitted via the Bluetooth transceiver 35 through the communications channel formed as described in the block 815, to the Bluetooth display device 20. The process 800 continues in a block 835.
In the block 835, the computer 38 determines whether a turn-off event has occurred. For example, the computer 38 may receive an input from the stationary display device 16 that the stationary display device 16 has been turned off. As another example, the computer 38 may receive an input from a user via the interface 36 that the quad AVB switcher 14 has been turned off. In the case that the computer 38 detects a turn-off event, the process 800 ends. In the case that no turn-off event is detected, the process 800 continues in a block 840.
In the block 840, the computer 38 determines whether new user input, requesting, for example switching from a first media source to a second media source. In the case that new user input has been received, the process continues in the block 825. Otherwise, the process 800 continues in the block 835.
