Abstract:

Representative embodiments are disclosed of a system and method for linearly exposing client-server interaction comprising interpreting a function command representing a first group of sequential action requests to an integrated multimedia communication server (iMCS), sequentially transmitting the first group of sequential action requests from an interactive multimedia runtime (iMR) client to the iMCS, wherein a next sequential action request of the first group is transmitted to the iMCS prior to receiving a response message from the iMCS associated with a previous sequential action request of the first group, queuing response messages received from the iMCS, and handling the queued response messages.

US Classification:

719316, 709224, 709248, 707203, 715511

Abstract:

A system and method are disclosed for an interactive multimedia file (iMF), running on an interactive multimedia runtime (iMR), to store an object onto a computer, the method comprising creating a local instance of the object, storing the local instance into a memory location on the computer, monitoring changes to one or more data slots of the local instance, assigning a version identifier to the local instance, synchronizing the local instance with a main instance of the object, and interfacing the one or more data slots of the local instance with said iMF during execution.

Abstract:

A system and method is disclosed for establishing an interactive multimedia application environment in which server-side streaming media may be controlled by a client using a programming model provided at both a communication server and an interactive multimedia runtime on the client. The application program interface (API) preferably provides methods for the client user to establish a stream of data from the client to the communication server in addition to allowing a stream from the communication server to the client. The API also preferably allows the user at a client to exert control over the broadcasting of the media streams. Streams may be built, edited, paused, stopped, augmented, and the like by the client user. Each function that the client user may operate on the broadcast media stream is preferably viewable by all of the other subscribing clients.

International Classification:

G06F 15/16
G06F 15/173

US Classification:

709224, 709203, 709217, 709223

Abstract:

A computer-implemented method including receiving, at a server, a first request for content; determining whether the content is available locally at the server; when the content is available locally at the server, retrieving the content locally at the server; and transmitting the content to at least one downstream server; and when the content is not available locally at the server, transmitting, to the at least one downstream server, a notification that the content is not available locally and that a second request for the content is being transmitted; and transmitting the second request for the content to at least one upstream server.

Abstract:

Methods, systems, and apparatus, including computer program products, for using data keyframes. In one aspect, a method includes storing a data keyframe transmitted as part of a live streaming broadcast; receiving a request from a client to join the live streaming broadcast in-progress; determining that the stored data keyframe was transmitted before the request from the client was received; transmitting the stored data keyframe to the client; and distributing streaming content associated with the live streaming broadcast to the client. Further, the data keyframe can be generated by a publisher of the live streaming broadcast. Distributing streaming content further can include storing a plurality of data keyframes transmitted as part of the live streaming broadcast and transmitting the plurality of stored data keyframes to the client before distributing streaming content associated with the live streaming broadcast to the client.
