20090164655 | Real-Time Network Transport Protocol Interface Method and Apparatus - An electronic device has a multimedia framework including an integration layer and a higher-level application layer. The integration layer includes predefined media processing components having an input/output interface configurable based on the type and format of media content delivered to the device during a streaming media session and that provide predefined media processing functions to the application layer for enabling playback of the media content. A streaming media management component included in the integration layer establishes and manages the streaming media session and configures one or more content pipes used during the streaming media session to access packets received by one or more sockets. The component also maps the content pipes to the sockets and processes packets retrieved from the one or more content pipes such that the media content is provided to corresponding ones of the predefined media processing components in accordance with their configured inpuvoutput interfaces. | 06-25-2009 |
20100169504 | Service Layer Assisted Change of Multimedia Stream Access Delivery - A streaming server sends a multimedia stream for delivery by a hybrid unicast-broadcast delivery network to a mobile terminal. To assist that mobile terminal change access delivery from unicast to broadcast, the streaming server sends multimedia content timing information that indicates one or more interstices in the content of the multimedia stream. The mobile terminal receives such multimedia content timing information upon receiving the multimedia stream by unicast. Although the mobile terminal determines the same multimedia stream is also available by broadcast, the mobile terminal initiates a change from unicast to broadcast during an interstice. Because the mobile terminal delays the access change until an interstice, any data loss resulting from the access change has a minimal effect on a subscriber's experience of the multimedia content. Moreover, regular occurrence of interstices ensures that such change will not be significantly delayed, and thus, neither will use of broadcast. | 07-01-2010 |
20120110120 | Methods and Devices for Media Description Delivery - Methods and devices for providing a media description of a media stream to a client are described. The client is subscribed to a media description delivery service. The media description delivery service comprises a media description delivery rule. A request for a media description delivery is sent to a media server. From the media server a media description is received. It is verified that the received media description complies with the media description delivery rule and if the verification is in the affirmative, a delivery of the media description is initiated to the client. | 05-03-2012 |
20120290644 | Methods and Arrangements for HTTP Media Stream Distribution - A method performed by a server of a communication network for making an HTTP media stream accessible to a client is provided. A Media Presentation Description (MPD) is generalized, such that the MPD is provided with at least one period element sequentially arranged according to a media play timeline. Each period element is provided with at least one representation such that at least one of the period elements is provided with at least two alternative representations. Each representation is provided with an ordered sequence of at least one media segment URI. Each media segment URI references at least one media segment of the HTTP media stream. The generated MPD enables a client to select representations and to acquire referenced media segments based on the selected representations. | 11-15-2012 |
20140140253 | TECHNIQUE FOR MANAGING STREAMING MEDIA TRAFFIC AT A NETWORK ENTITY - A method for managing streaming media traffic at a network entity capable of assuming a first and a second radio channel state, a transition from the first to second radio channel state requiring a first predetermined time period t | 05-22-2014 |
20150207838 | PROCESSING OF MULTIMEDIA DATA - Techniques for providing media content to an adaptive HTTP streaming player. Upon reception of a HTTP request from the adaptive HTTP streaming player, like a DASH player, requesting the media content, a HTTP entity performs a procedure for determining a representation preference indication of the content being available on a fixed quality interface providing data with fixed data quality, which may provide data being for example received over a broadcast interface or being available in a cache. Said representation preference indication is signaled to the adaptive HTTP streaming player, which is adapted to use the representation preference indication for further requests. The adaptive HTTP streaming player is not aware whether the content is available on a fixed or unicast interface, but is forced with the solution to use the preferred representation being available on the fixed quality interface. | 07-23-2015 |
