Traditionally, playback of digital media content (e.g., movies, music, pictures, games, etc.) has been constrained to the computing device (e.g., desktop computer, smartphone, tablet, wearable, gaming system, television, etc.) on which the digital media content was stored. However, with the advent of cloud computing related technologies and increased capabilities of computing devices, services such as digital media content transmission services (i.e., streaming, casting, mirroring, etc.) have spurred along the generation, sharing, and consumption of digital media content as consumer devices capable of interacting with such content have become ubiquitous. The desire to share digital media content between consumer interfacing computing devices, such as in home, office, and classroom environments, is increasing in tandem with the increased exposure of consumers to the digital media content and providers of such digital media content.
The introduction of stream-enabled computing devices has enabled digital media content to be streamed, casted, or mirrored from one computing device (e.g., a smartphone, a laptop, etc.) to one or more other compatible computing devices (e.g., laptops, tablets, wearables, smart televisions, speakers, etc.) directly, or indirectly, such as via a compatible hub, dongle, etc., connected to the other computing device. In other words, digital media content stored on a source computing device can be transmitted to one or more destination computing devices and received/rendered at the respective destination computing device(s). One such present solution is multicasting, in which the source computing device broadcasts a single digital media transmission stream to a group of destination computing devices. However, since the digital media is being transmitted through a single stream and all of the destination computing devices may not have the same or similar capabilities, the source computing device is restricted to transmitting the digital media stream using the lowest common minimum parameters (e.g., Wi-Fi capabilities, digital media types, graphic processing capabilities, etc.) as determined between all of the destination computing devices.

In block 508, the wireless retransmission hub 106 updates a list of connected destination computing devices to include the destination computing device connected to in block 504.
Referring now to
In block 608, the wireless retransmission hub 106 determines whether any destination computing devices are available for selection. To do so, the wireless retransmission hub 106 may determine which destination computing devices are presently connected and, of those presently connected, which are not presently assigned (i.e., selected by) to another active source computing device. As described previously, in some embodiments, more than one input digital media stream may be assigned to one or more destination computing devices. In such embodiments, the wireless retransmission hub 106 may be configured to allow the source computing device to select a destination computing device that is presently assigned (i.e., selected by) to another active source computing device. However, in some embodiments, the wireless retransmission hub 106 may enforce a maximum number of active source computing devices that may be assigned to a single destination computing device.
If so, the method 600 advances to block 610, in which the wireless retransmission hub 106 prompts the source computing device to select which destination computing devices are to receive digital media. In other words, the wireless retransmission hub 106 prompts the source computing device to select which destination computing devices are to receive the digital media corresponding to the input digital media stream to be transmitted by the source computing device. In block 612, the wireless retransmission hub 106 determines whether any destination devices have been selected by the source computing device.
If so, the method 600 advances to block 614, in which the wireless retransmission hub 106 updates a list of selected destination computing devices based on the destination computing devices selected by the source computing node in block 612. In block 616, the wireless retransmission hub 106 transmits a notification to the source computing device indicating that the selected destination devices have been updated, and that the source computing device may not transmit a digital media stream (i.e., an input digital media stream) to the wireless retransmission hub 106. From block 612, the method 600 returns to block 602 to determine whether a source computing device that is not presently connected has been detected.

To do so, in block 706, the wireless retransmission hub 106 transcodes each of the content streams based on the digital media display capabilities of the corresponding destination computing device. It should be appreciated that, based on the digital media display capabilities of the corresponding destination computing device, the input digital media stream may be transmitted as-is (i.e., without transcoding). As described previously, in some embodiments, more than one input digital media stream may be received that is to be transmitted to one or more destination computing devices. In such embodiments, the transcoding of the data in block 704 may include composing a single stream that includes each input digital media stream, resulting in a single output digital media stream.
In block 708, the wireless retransmission hub 106 transmits the digital media streams (i.e., the output digital media streams), either transcoded or as-is, to the corresponding (i.e., selected) destination computing devices. In block 710, the wireless retransmission hub 106 determines whether to end transmission of the output digital media streams. It should be appreciated that the wireless retransmission hub 106 may make the determination to end transmission of the output digital media streams based on various conditions, such as having received an indication from the source computing device that the transmission of the digital media stream has ended, determining the source computing device is no longer connected to the wireless retransmission hub 106, determining the destination computing device is no longer connected to the wireless retransmission hub 106, etc.
If the wireless retransmission hub 106 determines to end transmission of the output digital media streams, the method 700 advances to block 712, in which the wireless retransmission hub 106 transmits a notification to the corresponding destination devices indicating the retransmission has ended; otherwise, the method 700 returns to block 702 to determine whether digital media was received for retransmission.
It should be appreciated that at least a portion of the methods 500, 600, and 700 may be embodied as various instructions stored on a computer-readable media, which may be executed by the processor 302, the communication circuitry 310, and/or other components of the wireless retransmission hub 106 to cause the wireless retransmission hub 106 to perform the methods 500, 600, and 700. The computer-readable media may be embodied as any type of media capable of being read by the wireless retransmission hub 106 including, but not limited to, the memory 306, the data storage device 308, a local memory of a NIC (not shown) of the communication circuitry 310, other memory or data storage devices of the wireless retransmission hub 106, portable media readable by a peripheral device of the wireless retransmission hub 106, and/or other media.
