Systems and methods for using seektables to stream media items
A client device receives a request to stream a media item from a first position. Content corresponding to the media item includes samples identified in a container file for the media item. The client device obtains, independently of the container file, a seektable that is not included with the container file and that identifies a plurality of segments into which content corresponding to the media item is divided. Each segment of the plurality of segments includes multiple samples. The client device consults the seektable to determine a segment of the media item to retrieve in response to the request. The segment includes content at the first position. After consulting the seektable, the client device retrieves the segment of the media item and plays the content corresponding to the first position using the retrieved segment.
Feedback optimized video coding parameters
A system for managing delivery of video content. The system includes a controller and one or more players. The controller may be configured to control generation of a plurality of streams containing the video content based upon feedback regarding decoding at least one of the plurality of streams. The one or more players may be configured to select a stream from the plurality of streams, generate decoding statistics for the selected stream, and send the decoding statistics to the controller as the feedback.
Optimizing synchronization of audio and network tasks in voice over packet switched networks
A user equipment device (UE) comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network, an audio subsystem configured to generate frames of audio data, and processing circuitry. The processing circuitry is configured to calculate a time delay from generation of an audio data frame by the audio subsystem of the UE device to transmission of an audio data packet by the physical layer circuitry during a voice call, and decrease the time delay to a delay value that preserves a specified minimum time for delivery of the generated audio data frame to the physical layer circuitry to meet a scheduled transmission time of the audio data packet.
Social network account assisted service registration
An example implementation may involve a control device displaying, on a graphical interface, a prompt for login credentials. The example implementation may also involve the control device detecting input data at the prompt indicating a login credential for a given account of a social networking service. The example implementation may further involve the control device querying the social networking service for streaming media services that are associated with the given account of the social networking service. In response to the query, the control device may receive data indicating a first streaming media service that is associated with the given account of the social networking service. The example implementation may involve registering the first streaming media service with a media playback system and populating a queue of the media playback system with one or more particular media items from the first streaming media service.
System and Method for Determining Trust for SIP Messages
A method for performing initial registration is provided. The method includes receiving a server timeout message, the server timeout message including at least a field set to a value equal to a value received during a first registration. The method further includes initiating restoration procedures by performing an initial registration.
Establishment of a Secure Connection for a Communication Session
A system, method, node, user equipment and computer program for establishment of a secure connection between a user equipment (100) and a media gateway (130) at setup of a communication session with another party (150) is described. The media gateway (130) is controlled by a control server (120). The control server (120) receives a communication session setup request from the user equipment (100) and determines an indication of a security certificate of the media gateway (130). The control server (120) then sends the indication of the security certificate of the media gateway (130) to the user equipment (100), wherein the indication is sent before or in parallel to sending the communication session setup request towards said other party (150). The user equipment (100) then initiates a negotiation of security related parameters, based on the received indication of the security certificate of the media gateway (130). Then the secure connection between the user equipment (100) and the media gateway (130) is established, utilizing the negotiated security related parameters.
Modification of local logs by enterprise hub
An enterprise hub receives a first local log from a first transaction delivery system of a first media outlet, and a second local log from a second transaction delivery system of a second media outlet The local logs represents media items scheduled for delivery by the media outlets. The enterprise hub also receives a first avail claim, to be inserted into both the first local log and the second local log, from a first content provider. The enterprise hub inserts the first avail claim into the first local log to generate a first revised log, and into the second local log to generate a second revised log. The first and second revised logs are transmitted from the enterprise hub to the corresponding first or second media outlet.
Virtual playback speed modification
A multispeed playback system is described herein that allows for playback of smooth streaming media presentations at speeds other than the normal speed or direction, while still using an underlying platform that does not natively support multispeed. The system provides frames to the underlying platform so that the platform is still playing 1× content while the system manipulates video and/or audio samples being fed to the platform to make rendered data look appropriately for a selected speed and direction. The system may feed the underlying platform frames at a faster rate or skip every other frame for faster playback, or may feed each frame to the underlying platform multiple times for slower playback. Thus, the multispeed playback system allows a client application developer to provide users with expected multispeed playback at the client without encoding multiple different streams at the server.
System and method for selecting a content delivery network
A system and method for selecting a data delivery network. A determination is made of user information associated with a communication from a user. A determination is made of performance information for multiple data delivery networks. The data delivery network is selected for the communication from the multiple data delivery networks.
Emergency alert data delivery apparatus and methods
Apparatus and methods for efficiently and flexibly providing emergency alert data (e.g., EAS messages) to subscribers of a content-based network, such as for example Internet protocol television (IPTV) subscribers. In one exemplary embodiment, the apparatus includes a server performing real-time receipt and encapsulation of the EAS data (which may comprise audio, video, and/or text), transport of the EAS data to client devices over the network, and use of one or more applications running on the client devices to decode and display/present the EAS data in a manner which effectively guarantees that it will be perceived by the viewer. In one variant, instant messaging (IM) infrastructure is used to authenticate clients and receive and display at least portion of the EAS data via a separate transport process. Server and client-side apparatus adapted for EAS data receipt, decoding and display are also disclosed.
