Audio content may be played on multiple audio-enabled devices via a voice command issued by a user. The voice command is received at a first audio-enabled device and processed, via speech recognition, to identify the audio content to be played and the target devices on which the audio content is to be played. In addition, the voice command can also indicate the time periods associated with the audio playback to provide synchronized playback. Device set information can be used to determine if the first audio-enabled device shares audio functionality with the target devices. If shared functionality is confirmed, one or more commands are sent to the respective target devices to instruct the corresponding playback of the audio content.

Playback of audio content on multiple devices

Described herein are systems and methods for a media controller configured to associate data from a media device received using a media device interface with actions on the media devices. The associated data and actions may be used to build a media device interface command map. The media device interface command map may be used by the media controller to control the media device. A user interface provided by the media controller may thus be used to control disparate devices, allowing for a coordinated and consistent user experience across multiple media devices, even when they are from different manufacturers.

Determining commands on a media device interface

Techniques are described for shared audio functionality between multiple computing devices, based on identifying computing devices in a device set. The devices may provide audio output, audio input, or both audio output and input. The devices may be organized into one or more device sets based on location, supported functions, or other criteria. The shared audio functionality may enable a voice command received at one device to be employed for controlling audio output or other operations of other device(s) in the device set. Shared audio functionality between devices may also enable synchronized audio output through using multiple devices.

Shared audio functionality based on device grouping

Techniques are described for shared audio functionality between multiple computing devices, based on grouping the multiple computing devices into a device set. The devices may provide audio output, audio input, or both audio output and input. The devices may discover each other via transmitted radio signals, and the devices may be organized into one or more device sets based on location, supported functions, or other criteria. The shared audio functionality may enable a voice command received at one device in the device set to be employed for controlling audio output or other operations of other device(s) in the device set. Shared audio functionality between devices in a device set may also enable synchronized audio output through using multiple devices in the device set.

Device grouping for audio based interactivity

A computing device is used to acquire data and information regarding various electronic devices within a home, commercial space, or another area of interest. Locations for the electronic devices may also be determined by way of a location resource of the computing device, by user input, or through another suitable technique. Various maps may be generated that include graphical representations of the electronic devices, as well as walls, doorways, furniture, or other features within the area or space of interest. A user may amend or add various details within such a map by way of respective user interfaces presented by the computing device. The respective functions and cooperative operations of the electronic devices may be visualized and improved through such mapping.

Mapping electronic devices within an area

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and encoded auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, and methods for sending encoded data over a serial link. In accordance with the invention, the data to be transmitted are encoded using a subset (sometimes referred to as a selected set of code words) of a full set of code words. The selected set of code words is selected such that each stream of encoded data (comprising only such code words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference ('ISI') during transmission than is the bit pattern determined by a conventionally encoded version of the same data (comprising not only the selected set of code words but also other members of the full set). In general, the best choice for the selected set of code words selected from a full set of binary code words depends on the particular coding implemented by the full set. Typically, the selected set of code words includes words whose serial patterns (during transmission) have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do those code words in the full set that are not selected. In preferred embodiments in which the bits of the selected set of code words are transmitted over a serial link as sequences of rising and falling voltage transitions, the bit pattern of each transmitted stream of the selected set of code words implements DC balancing to limit the voltage drift over time.

Encoding method and system for reducing inter-symbol interference effects in transmission over a serial link

A system in which encoded data (e.g., encoded video and auxiliary data) are transmitted over a serial link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. Source data to be transmitted are encoded using a subset of a full set of code words. The subset consists of preferred code words. Disjoint clusters of code words in the full set are predetermined. Each cluster includes one or more of the preferred words, and optionally also at least one additional code word that is similar to a preferred word of the cluster in the sense that it is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. Each preferred word of a cluster is indicative of a single source data value. Each received code word in a cluster is mapped to the source data value determined by each preferred word of the cluster.

Method and system for reducing inter-symbol interference effects in transmission over a serial link with mapping of each word in a cluster of received words to a single transmitted word

A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data, a pixel clock is transmitted over the link, and the receiver regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.

A data bus arbitration system is disclosed including a bus status monitor which is coupled to a data bus and generates a bus status signal for use by an arbiter. The arbiter is coupled to a number of requesters, each of which belongs to a distinct class of requesters. The arbiter arbitrates between multiple requests using heuristics dependent upon the classes of the requesters. The nature of one class of requestors is that the requestors have real time requirements which must be met in order to maintain data integrity within the system. The nature of a second class of requestors is such that the requestors have semi-real time requirements which must be met in order to maintain data integrity within the system. The nature of the system is such that the available bandwidth must be utilized very efficiently in order to maintain data integrity within the system. The arbiter system disclosed grants access to the requesters using the heuristics disclosed while maintaining an efficiency of at least 80% of the total bandwidth for all requestors.

Methods and apparatus for data bus arbitration

Disclosed is a SDRAM system including a SDRAM having multiple banks of memory, a plurality of bank state machines associated the multiple banks of memory of the SDRAM, and a data control state machine. The data state machine is responsive to a memory request for a variable length data transfer with the SDRAM and as well as the bank state machines. The data control state machine determines the current state of a first bank of memory of the SDRAM. The current state may be either a read in progress, a write in progress, or idle. The data control state machine then handles the memory request with a different bank of memory RAM depending upon the current state of the first bank of memory.
