  • Publication number: 20170214958
    Abstract: A mobile video system includes a first video source, a second video source, a first video monitor, a second video monitor, an audio signal receiver, and a wireless transmitter. One of the first video source and the second video source generates a first audiovisual signal. One of the first video monitor and the second video monitor receives a video portion of at least one of the first audiovisual signal and the second audiovisual signal. The wireless transmitter transmits an audio portion of one of the first audiovisual signal or the second audiovisual signal to the audio signal receiver. A video portion of the first audiovisual signal or the second audiovisual signal is displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

  • Publication number: 20170195769
    Abstract: Wireless speaker systems and methods for synchronous audio playback. Speaker systems can comprise more than one wireless speaker assembly, such as wireless earphones, in serial communication with an audio source device, such as a smartphone. Separate audio rendering by each wireless speaker assembly and synchronization of audio playback by imposing a fixed latency from an output timestamp associated with the audio source data, and rate matching the sample allow for tightly synchronized playback of stereo audio at low latency.

  • Patent number: 9340133
    Abstract: A monitor adapted for mounting in an automobile headrest is provided. A screen structure of the monitor is pivotable about an upper edge thereof, such that the monitor occupies little volume within the headrest. A viewing angle of the screen structure is independently adjustable by a viewer, such that the viewer can continuously select the optimum viewing angle with changing conditions inside the automobile. The screen structure automatically retracts into a housing when struck. Thus, the monitor poses little risk of injury to passengers. The housing of the monitor is attachable to the headrest with screws, which provides a very sturdy connection and reduces the chances of the housing becoming detached from the headrest during a vehicle collision. The hinged connection between the screen structure and the housing is preferably constructed of interconnected components made from sturdy materials, such as metals.
