摘要： 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.

摘要： 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.

摘要： 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 segments 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.

摘要： A method is described for transmitting a multimedia stream from a first terminal and receiving an associated second multimedia stream at a second terminal. The first and second terminal are connected to at least one gateway for enabling the transmission of the stream and the receiving of the associated stream. The method comprises: —initiating the exchange of first multimedia session information between the first terminal and the gateway, using a first protocol; —providing a trigger to the second terminal to initiate the exchange of second multimedia session information between the second terminal and the gateway, using a second protocol; —in response to providing the trigger, the second terminal initiating the exchange of second multimedia session information between the second terminal and the gateway, using a third protocol; —transmitting a first multimedia stream from the first terminal and receiving a second associated multimedia stream at the second terminal.
