摘要： 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.

摘要： 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.

摘要： The invention relates to a system for receiving an interest message. The system comprises at least one communication interface, at least one memory and at least one processor. The at least one processor is configured to receive an interest message on a first one of the at least one communication interface. The interest message comprises a name of a requested data object. At least one name component of the name of the requested data object comprises a range. The at least one processor is further configured to determine whether the at least one memory comprises a named data object having a name matching the name of the requested data object and to provide the named data object on the first one of the at least one communication interface if the memory comprises the named data object. The at least one processor is also configured to, if the memory does not comprise the named data object, forward the interest message on one or more further ones of the at least one communication interface, associate the name of the requested data object with an identifier of the first one of the at least one communication interface in the at least one memory, receive the named data object on the one or more further ones of the at least one communication interface and forward the named data object on the first one of the at least one communication interface based on the association.
