Abstract: Embodiments described herein reduce latency and improve packet delivery when transmitting audio packets from a source device to one or more sink devices. For example, one or more operating modes that introduce latency when transmitting packets may be disabled at the source device and/or sink device(s). Additionally, certain operational behavior of the source device and/or sink device(s) may be changed based on the quality of the channel used to transmit audio packets to further improve the latency. Such operational behavior includes changing the jitter buffer size of the sink device(s), the number of retry attempts performed by the source device when re-transmitting packets that have been lost, and changing the channel used to transmit the audio packets. Embodiments described herein further enable the synchronization of playback between the sink devices to ensure that sink devices playback audio packets in a synchronized fashion.

Abstract: Methods, systems, and apparatuses are described for testing communication with a device. A multimedia receiver may be communicatively coupled to a media device, such as a source media device. The multimedia receiver may transmit a test command to control the source media device using a communication protocol. A video frame output by the source media device may be obtained. Based at least on the video frame, it may be determined whether the source media device received the test command. In response to a determination that the source media device received the test command, an indication may be stored that the source media device may be controlled using the communication protocol.

Abstract: Methods, systems, and apparatuses are described for source device detection. Source device detection may be performed for a variety of types of connectors such as cables or board/substrate connectors across which a DC voltage or stable presence signal is normally supplied during connections when the power signal of the connector is not present. An alternating power source is coupled to a capacitor of known capacitance via a switch. The capacitor is in series with an effective capacitance of a sink device, a connector, and a source device. When the switch is open, the voltage between the capacitor and the effective capacitor is read to determine if a source device is present and On, and when closed, if the source device is present and Off or in Stand-By, or not present. The methods, systems, and apparatuses described include tunability for the capacitor based on temperature and effective capacitance variations.

Abstract: Methods, systems, and computer program products are provided for obtaining enhanced metadata for media content searches. In one embodiment, computer program logic embodies a metadata receiver and a media content metadata matcher and combiner. The metadata receiver receives program metadata for a plurality of programs from a plurality of metadata sources. The media content metadata matcher and combiner is configured to perform a matching process whereby metadata associated with each of the plurality of programs is compared to metadata of each of the other plurality of programs to determine if the compared programs are the same program and if so, to combine the metadata from each program into a single program including enhanced metadata and store such in a database. A subsequent search for a program corresponding to the stored program returns at least some of the metadata associated with the program, and that enables accessing the program.

Abstract: Methods, systems, and apparatuses are described herein for enhancing metadata of a recorded items of media content stored on a digital video recorder (DVR) associated with an end user. First metadata associated with the recorded item is determined from the DVR. An aired instance of the first media content is determined in program data from an electronic program guide that corresponds to the recorded item. Second metadata associated with the first media content is retrieved from at least one data source based at least on the identifying information. The first metadata and the second metadata are stored in an end user database in association with the end user.

Abstract: Embodiments are described herein for enabling fast and efficient media content searches across a wide variety of content providers using a graph database. For instance, metadata may be collected from different metadata sources. A graph database is generated that stores and organizes the metadata based on attributes of the metadata and the relationships therebetween. For example, each attribute is assigned to a node of the graph database. The nodes may be connected via an edge that represents a relationship between the nodes. Attributes of metadata retrieved from a first metadata source are associated with attributes of metadata retrieved from a second metadata source. When receiving a query, the graph database is traversed for media content items to recommend to a user. The media content items recommended to the user include items from different content providers that are determined based on the traversal of the nodes of the graph database.

Abstract: Methods, systems, and apparatuses are described for determining a power state of a device. Identification data may be received, e.g., in a media device hub, from one or more devices coupled to the device hub. In some example implementations, the devices coupled to the device hub may comprise an intermediate device coupled to the hub via a first multimedia cable and a sink media device coupled to the intermediate device via a second multimedia cable. Attributes may be identified in the received identification data, such as attributes relating to one or more of the coupled devices. The attributes may be associated with one or more of the devices that are coupled to the device hub. Based on an association of attributes, a power state of one or more of the devices coupled to the hub may be determined.

Abstract: Methods, systems, and apparatuses are described for identifying devices coupled a media device hub. A device map in the media device hub may create a map entry that associates a first device, a port to which the first device was at least previously coupled, and a first key of the first device. A second key is obtained from a media device that is coupled to a current port of the media device hub. A determination is made whether the second key is the same as the first key stored in the device map. If the first and second keys are the same, a determination is made whether the current port to which the second device is coupled is different than the port indicated in the device map. If the current port is different than the indicated port, the device map is updated to indicate the first device as coupled to the current port.

Abstract: Methods, systems, and apparatuses are described for an adaptive multi-protocol control of a device. A plurality of communication protocols suitable for communication with a particular device may be determined. A request may be received to control the device, such as a via a remote control, voice control, etc. A first communication protocol from among the plurality of communication protocols may be selected to transmit a first control signal. The first control signal may be transmitted to the device using the first communication protocol. In some implementations, a second communication protocol may be selected for transmitting a second control signal to the device, such as where the request may be associated with a plurality of control commands or where the device did not react to the first control signal. As a result, a device may be controlled using one or more communication protocols in an adaptive fashion.

Abstract: Methods, systems, and apparatuses are described herein for determining distances and angles between speakers and other home theater components for performance of calibration operations and functions. Distances are determined through timing playback of sweep signals from a reference speaker to the speakers, and also by timing playback the sweep signals between the speakers and a capture device at a desired listening position. Angles between the speakers and other theater components are determined based on the distances, and locations or mappings of the speakers and other theater components are determined from the angles and distances. The locations/mappings are utilized to perform different calibration operations. The calibration operations improve the user audio experience for speakers that are located in non-optimal positions for speaker configurations.

Abstract: A loudspeaker system is described that includes a loudspeaker and an extender. The loudspeaker can be positioned on the ground and the extender can be optionally connected thereto. When the extender is connected to the loudspeaker, the loudspeaker is capable of selectively sending high-frequency components of an input audio signal to the extender and the extender is capable of playing back such high-frequency components to produce high-frequency audio. Due to the fact that an audio-producing apparatus of the extender can be positioned at a higher elevation than the loudspeaker, the high-frequency audio (which is more directional than lower-frequency audio) can be produced at a height that is likely to match that of the ear height of a user as opposed to producing the audio at floor height.

Abstract: Methods, systems, and apparatuses are described for automatically navigating a graphical user interface (GUI) of a media device. In embodiments, objects (e.g. selectable items) in device GUI menu screens may be located, identified, and selected by another device (e.g., a switch) using several types of image processing, image recognition, and automated screen navigation techniques. For instance, a device may receive an operation request, for example from a user, receive a video signal from the connected media device, extract a video frame, process the video frame using one or more algorithms, and automatically navigate the GUI of the device by transmitting one more navigation commands for application to the GUI. In this manner, multi-step, time-consuming manual GUI navigation to achieve a desired result may be reduced to an automated technique, allowing users to save time and frustration in navigating a GUI using a remote control to find a particular resource.

Abstract: A remote control is described herein that is configured to sense a variety of user input types on a specific button and that can also sense a variety of user input types on a click pad or region/location of the click pad. By utilizing these capabilities, the remote control can provide a very powerful and versatile user interface. Furthermore, the foregoing can be achieved with only a relatively small number of buttons, thus also providing a user interface that is simple, clean and elegant.

Abstract: Embodiments described herein enable a media device to be controlled from any location via a network-based device. For example, a user, using a control device, initiates a command that identifies media content to be streamed by the media device. The command is transmitted to a proxy device coupled to the media device and a network-based device. The proxy device transmits the command to the network-based device, which translates the command into a format compatible with the media device. The translated command is transmitted to the proxy device, which transmits the translated command to the media device. The media device streams the media content based on the received translated command. Alternatively, the control device and the proxy device are integrated as a single device, which generates and transmits the command to the network-based device, receives the translated command from the network-based device, and transmits the translated command to the media device.
