20130326082 | Fingerprint-Based Inter-Destination Media Synchronization - Methods and systems for inter-destination synchronization in first and second receivers for content parts associated with a play-out timeline are disclosed. First timing information comprising first content part identifiers and associated first clock times may be determined, where the first receiver may receive a first content part identifier comprising first fingerprints for identifying a first content part in a first media stream. Second timing information comprising second content part identifiers and associated second clock times may be determined, where the second receiver may receive a second content part identifier identifying a second content part in a second media stream based on the first and second timing information. A timing difference in processing a content part in the first and second media streams may be calculated. Based on the timing difference, synchronization information for inter destination synchronization between said first and second streams may be generated. | 12-05-2013 |
20140089465 | Locating and Retrieving Segmented Content - Methods and systems are described for retrieving segmented content originating from two or more content delivery networks. The method may comprise the steps of: retrieving a manifest file template associated with said segmented content comprising one or more pointers to database entries of said first content location database; using said one or more database entries for determining a location of a delivery node in said first or second content delivery network, said delivery node being configured for delivering a segment associated with said database entry; and, generating a manifest file for locating said segmented content by replacing pointers with said determined locations. | 03-27-2014 |
20140089990 | Spatially-Segmented Content Delivery - 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. | 03-27-2014 |
20140115724 | Token-Based Validation Method for Segmented Content Delivery - A token-based validation method for delivery of at least part of a segmented content item and a content delivery system configured for executing such method are described. Said segmented content item may be associated with at least one manifest file comprising one or more segment identifiers. The method may comprises the steps of: a content processing device sending a first segment request message comprising a first segment identifier associated with a first segment to said at least one delivery node; generating first validation information for use with a further second segment request message, said first validation information comprising at least a first token and associated first timing information; and, sending a first response message and said first validation information to said content processing device, said first response message comprising at least part of said segment or location information associated with at least one delivery node for delivering said segment. | 04-24-2014 |
20140359081 | CONTROLLED STREAMING OF SEGMENTED CONTENT - Methods and systems for enabling client-controlled streaming of segmented content are described. In one example, the client-controlled streaming is on the basis of a manifest file, the manifest file including one or more segment identifiers and one or more associated segment locators, In one example, a method involves: requesting the delivery of at least one segment on the basis of a first segment identifier selected from the manifest file; on the basis of the first requested segment, selecting a second at least one segment identifier from the manifest file, the second segment identifier being associated with an expected future segment request; and pre-resolving a first segment locator associated with the selected second segment identifier for obtaining network information associated with the first segment locator. | 12-04-2014 |
20140379871 | Network-Initiated Content Streaming Control - 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, said client being configured to access at least part of said segmented content on the basis of a manifest file, wherein a method may comprise: receiving a first manifest file identifying one or more segments and location information for locating one or more content delivery nodes configured to transmit said one or more segments to said at least one client; in response to said reception of said first manifest file, providing channel set-up information; and, establishing at least one streaming control channel between said at least one client and a control channel server function associated with said content delivery node on the basis of said control channel set-up information, said at least one client being configured for receiving at least one manifest file update message via said streaming control channel. | 12-25-2014 |
20150052571 | Marker-Based Inter-Destination Media Synchronization - A method and a system enabling inter-destination synchronization of processing of content of at least a first and second media stream, wherein said first and second media stream are associated with one or more markers for marking one or more content parts of said first and second media streams respectively. The method comprises the steps of: detecting a first marked content part in said first media stream and a second marked content part in said second media stream, said first and second market content part being associated with a first and second marker respectively; associating first timing information, preferably comprising a first clock time, with said detected first marked content part and associating second timing information, preferably comprising a second clock time, with said detected second marked content part; determining a timing difference on the basis of said first and second timing information; and, generating on the basis of said timing difference synchronization information for enabling a first and/or second synchronization client to adjust the processing of said first and/or second media stream respectively. | 02-19-2015 |
20150334153 | Low-Latency Streaming - Method and systems for enabling low-latency streaming of segments over at least one network to a client are described wherein said client is configured to request and receive segments from at least one server on the basis of a manifest file. Said method comprises: collecting quality of service information experienced by said client in at least a part of said network and storing said quality of service information in a quality database in said network; sending at least part of said quality of service information to said content processing device; determining on the basis of said at least part of said quality of service information one or more configuration parameters for a buffer, preferably a play-out buffer; and/or, for a segment request function in said content processing device; and, configuring said buffer and/or, said segment request function in accordance with said configuration parameters. | 11-19-2015 |
