  • Patent number: 11115617
    Abstract: An apparatus, method and system for connecting High-Definition Multimedia Interface (HDMI) devices. A loopback device connects between a first source device and a sink device on a first connection; a second source device connects to the sink device on a second connection. The loopback device manages the first connection, passes transition-minimized differential signaling (TMDS) or fixed-rate link (FRL) signals through to the sink device, and outputs audio received from the sink device on the audio return channel (ARC) or enhanced audio return channel (eARC). In this manner, audio that originates from any source device may be output without requiring a direct connection to the loopback device.

  • Patent number: 10491851
    Abstract: A system and method of interfacing between a source media device, a destination media device and wireless speakers. A media stick provides the output video signal to the destination media device via a wired signal path, and provides the output audio signal to the wireless speakers via a wireless signal path. In this manner, a user may use a single device—the media stick—as both a connector between the devices and to provide the audio signal to the wireless speakers.

  • Patent number: 9875751
    Abstract: Embodiments are directed processing adaptive audio content by determining an audio type as one of channel-based audio and object-based audio for each audio segment of an adaptive audio bitstream, tagging the each audio segment with a metadata definition indicating the audio type of the corresponding audio segment, processing audio segments tagged as channel-based audio in a channel audio renderer component, and processing audio segments tagged as object-based audio in an object audio renderer component that is distinct from the channel audio renderer component. Object-based audio is rendered through an object audio renderer interface that dynamically adjusts processing block sizes of the object audio segments based on timing and alignment of metadata updates and maximum/minimum block size parameters.

  • Patent number: 9288509
    Abstract: A second screen communication device that is paired with an automatic content recognition (ACR) enabled display communication device is operable to detect presentation of a linear advertisement campaign on the ACR-enabled display communication device and control presentation of content, which is associated with the linear advertisement campaign, on the second screen communication device. The content that is associated with the linear advertisement campaign comprises a plurality of messages. The second screen communication device is operable to select one or more of the plurality of messages for presentation on the second screen communication whenever the linear advertisement campaign is detected during the presentation on the ACR-enabled display communication device. The screen communication device may be operable to sequence through presentation of the plurality of messages on the ACR-enabled display communication device based on the selection.
