  • Patent number: 9860572
    Abstract: Methods and systems are described for processing spatially segmented content originating from a content delivery network. One method comprises a client in a media processing device receiving a spatial manifest information comprising one or more spatial representations of a source stream, each spatial representation identifying one or more spatial segment streams, location information for locating one or more delivery nodes in said content delivery network and, optionally, position information for stitching spatial segment frames in said segment streams into a video frame for display; selecting one or more spatial segment streams and on the basis of said spatial manifest information requesting at least one delivery node in said content delivery network to transmit said one or more selected spatial segment streams to said client; and, receiving said one or more selected spatial segment streams from said at least one delivery node.

  • Publication number: 20170353747
    Abstract: The play-out of a media stream by a play-out device may be synchronized by a synchronization subsystem with a reference play-out, thereby obtaining a degree of synchronicity with the reference play-out. To address a structural deficiency in the obtaining of the synchronicity with the reference play-out, the play-out device may report a quality of sync metric to a metric subsystem, which may then be analysed to identify the structural deficiency. A corrective action may then be scheduled to address the structural deficiency. Examples of corrective actions include re-clustering of play-out devices, adjusting priority and/or bandwidth in the streaming, etc. As such, the quality of experience of one or more users experiencing the play-out may be improved.

  • Publication number: 20170353522
    Abstract: Methods and systems are described for enabling network-initiated control of streaming of segmented content from a content delivery node to at least one client, the client being configured to access at least part of the segmented content on the basis of a manifest file. A first manifest file is received identifying one or more segments and location information for locating one or more content delivery nodes configured to transmit one or more segments to at least one client. In response to reception of the first manifest file, channel set-up information is provided. At least one streaming control channel is established between at least one client and a control channel server function associated with the content delivery node on the basis of the control channel set-up information. The at least one client is configured for receiving at least one manifest file update message via the streaming control channel.

  • Publication number: 20170310731
    Abstract: A system and method are provided for managing a concurrent streaming of a first media stream (031) and a second media stream (032). The media streams (031, 032) represent different recordings of an event. The concurrent streaming of the media streams (031, 032) is enabled by a resource having a resource limitation (080). To address this resource limitation, when it is determined that the resource limitation is exceeded by the concurrent streaming of the first media stream (031) streaming to a first streaming client (041) and the second media stream (032) streaming to a second streaming client (042), the first media stream (031) is selected for substituting the second media stream (032) in the streaming to the second streaming client (042). As a result of the substitution, the first and the second streaming client (041, 042) stream the same media stream rather than different media streams.

  • Publication number: 20170213567
    Abstract: A play-out device is provided for playing out an audio signal via a speaker to provide a sound signal, and a recording device for recording the sound signal to obtain a recorded signal comprising a recording of at least the sound signal. The play-out device is configured for generating noise suppression data comprising the audio signal, or a reference thereto, and timing information for enabling the audio signal to be correlated in time with the recorded signal. A noise suppression subsystem is provided with the recorded signal and the noise suppression data. The noise suppression subsystem comprises a timing manager for synchronizing the audio signal with the recorded signal based on the timing information, and a noise suppressor for processing the recorded signal based on said synchronized audio signal to obtain a processed signal in which the recording of the sound signal is suppressed.

  • Publication number: 20170188170
    Abstract: In an embodiment, an audio system may include a first set of speakers arranged in a first area, a second set of speakers arranged in a second area, an audio source for supplying sound signals to the speakers, and at least one detector for detecting the location of a user and for supplying a location signal to the audio source. The first area and the second area may be substantially non-overlapping. The audio source may be configured for controlling the sound signals to the speakers so as to produce a sound field having a position. The audio source may further be configured for adjusting, in response to the at least one location signal, the position of the sound field when a user moves from the first area to the second area. As a result, the position of the sound field may substantially coincide with the location of the user.

  • Publication number: 20170186463
    Abstract: A system and method are provided for enhancing an audio recording which comprises a recording of a sound signal obtained from the play-out of an audio signal via a speaker. The audio signal, and thereby the sound signal, may represent certain audio content, e.g., a radio station or TV audio. To perform the enhancing, the recording of the sound signal is suppressed using the audio signal, thereby obtaining an intermediate audio recording. An original version of the audio content is then added to the intermediate audio recording to obtain an enhanced audio recording. This original version is generally of higher quality as it generally does not represent a background audio component but rather was purposefully recorded or generated.

  • Patent number: 9538212
    Abstract: A method of generating a stream comprising synchronized interactive content is described. The method comprises the steps of: transmitting a first stream from a studio to a terminal or a terminal system of a first user and to a buffer; transmitting in response to the first stream a second stream to a mixer connected to the buffer, the second stream comprising content generated in reaction to the content of the first stream; providing the mixer with a temporal relation between the packets in the first and second stream; generating a first output stream comprising a substantially synchronized content by mixing packets in second stream with packets of the buffered first stream on the basis of the temporal relation.

  • Publication number: 20160353148
    Abstract: The invention provides a streaming client with a streaming presentation of an event, with said presentation being obtained by dynamically switching between a plurality of media streams which represent different recordings of the event. For that purpose, source data is obtained from a plurality of stream sources. The source data is constituted by content data and/or metadata of concurrent portions of the plurality of media streams. By applying a quality assessment function to the source data, a quality score is assigned to each one of the concurrent portions. This allows selection data to be generated which enables the streaming client to access a selected one of the concurrent portions of a respective media stream. For example, a segment may be selected which provides a highest quality score. By doing so, it is therefore not required anymore for a consumer to manually switch between different media streams.
