  • Patent number: 9743147
    Abstract: Providing content to content receiving devices, such as digital video recorders, connected to a computer network through a content provider is described. According to one aspect, a server maintains a database correlating contact information to content receiving devices in its network. A user navigates to a web site of the content provider and selects a piece of content, which prompts the content provider to query the server for the contact information, and then transmit a request to download the piece of content to the content receiving device. The request can be a set of content identification information that automatically populates a content guide at the receiving device with an entry corresponding to the requested piece of content. This entry allows the user to confirm, interrupt, resume and cancel a download of the content as desired.

    Abstract: A method of adjusting an audio signal equalizer setting. A first and a second equalizer setting are selected from a population of equalizer settings for undergoing a binary comparing decision. The two equalizer settings are presented to a user by consecutively replaying an audio signal filtered by an equalizing unit according to the first or to the second equalizer setting respectively. The user's binary comparing decision between the first and the second equalizer setting according to his preferences is acquired. Further binary comparing decisions are performed until all members of the settings population have been part of a binary comparing decision. A score for the each presented equalizer settings is adapted based on the user's binary comparing decisions results. A weighted averaging is performed, based on the scores, in the frequency domain between the equalizer settings that received a high score, to obtain the result of the equalizer adjustment method.

  • Patent number: 9626372
    Abstract: A method and system concatenate multiple media files into a single, continuous media file. The method includes receiving a group of media files and metadata about the group over a network connection. The method also includes in response to receiving the group of media files, determining an order of the media files in the group based at least partially on the metadata. The method includes concatenating the group of media files into a concatenated file based on the determined order. The concatenated file may be transferred to a client device over a network connection. The concatenated file may be transcoded into a file format determined based on the user device before transferring the concatenated file to the user device. The order of the media files in the group may be determined based on a timecode for each of the media files, which is included within the metadata.

  • Patent number: 9620131
    Abstract: Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

  • Patent number: 9619431
    Abstract: A music and audio playback system is implemented on a computer with a playback engine that enables the operator to apply a variety of effects. The system may store one or more snapshots, or a combination of settings for a plurality of controls that are applied by the playback engine. These snapshots allow for changes to settings for effects, mixing and playback to be made quickly, some of which would normally be difficult to perform. A sampler module permits a user to specify one or more samples that may be triggered for playback. The most frequently used samples may be designated as scratching files that may be quickly activated through the push of a button (or other control). Additionally, a waveform display represents a window of audio samples around a current playback time.

  • Patent number: 9619198
    Abstract: Disclosed are methods and systems for dynamically playing audible punctuation in connection with playout of content defined by a playlist. A client receives a playlist defining a sequence of media content items to be played out by the client, the playlist indicating attribute data for each media content item of the sequence. For each of at least one of the media content items of the playlist, the client determines based on the attribute data and perhaps based on user preference data an audible punctuation to play out in connection with playout of that media content item, and the client retrieves and plays out the audible punctuation in connection with playout of that media content item.

  • Patent number: 9606766
    Abstract: An approach is described for creating an audio file sample based upon user preferences. An associated method may include detecting selection of an audio file by a user, wherein the selection of the audio file occurs via a communications network and indexing the audio file to create a plurality of indexed segments based upon audio analysis. The method further may include selecting at least one segment among the plurality of indexed segments based upon a profile of the user and incorporating the at least one selected segment into an audio sample having a designated length. Indexing the audio file to create a plurality of indexed segments based upon audio analysis may include, for each audio characteristic among a plurality of designated audio characteristics, creating from the audio file at least one indexed segment corresponding to the audio characteristic.

  • Patent number: 9589027
    Abstract: Techniques for identifying video and/or audio content are presented. An identification management component (IMC) groups users determined to be at least potentially be watching the same content based on first content fingerprints associated with respective content viewed by the users on communication devices, and a defined matching criterion. IMC facilitates identifying the content associated with the group of users based on first content fingerprints associated with the group of users and first reference content fingerprints. IMC receives a second content fingerprint associated with a communication device of a user in the group, sends the second content fingerprint to a third-party identification component for comparison with second reference content fingerprints, and receives content identification information in response.

  • Patent number: 9589052
    Abstract: A remote node for bi-directional digital audio data and control communications includes remote components including: a remote transceiver; a remote low-voltage power supply that provides power to the other remote node components; and a sub-system that derives a master clock signal from received digital audio data. The sub-system includes a phase-locked loop (PLL) that is locked to a PLL input signal and outputs a remote node clock signal, and a switch that selects the PLL input signal from the derived clock signal and the remote node clock signal. The remote node is enabled to receive over a two-wire communication network digital audio data and digital control signals, and to transmit over the network digital control signals. The remote power supply has an input that is configured to be coupled to the network to derive the power for the remote node from power coupled to the network by a host end.
