Abstract

Systems and methods for multimedia swarm processes in accordance with embodiments of the invention are illustrated. One embodiment includes a method for creating a multimedia project at a swarm interface device. The method includes steps for providing a first set of multimedia content to a swarm includes several swarm members, where the several swarm members includes several swarm sources. The method further includes steps for receiving a second set of multimedia content from the several swarm sources and editing multimedia content to create a multimedia project includes at least one piece of multimedia content from the first set of multimedia content and at least one piece of multimedia content from the second set of multimedia content.

Abstract

Systems and methods for partial frame encryption in accordance with embodiments of the invention are disclosed. In one embodiment, the method receives a video bitstream that includes several frames, each frame including several independently encoded compression units within the frame, encrypts a portion of each of several compression units in several frames, and generates an output bitstream that includes the several independently encoded compression units including the encrypted portions of the compression units.

Abstract

Systems and methods for adaptive bitrate streaming of media stored in Matroska container files utilizing Hypertext Transfer Protocol (HTTP) are disclosed. In one embodiment, a processor requests portions of files from a remote server and retrieves top level index data that identifies EBML container files and describes a maximum bitrate of the alternative streams contained within the EBML container files. The top level index data is parsed to obtain information identifying the EBML container files, requests a portion of at least one of the EBML container files that contains the at least one element that specifies the encoding parameters of the stream contained within the EBML container file, and requests portions of a first EBML container file that includes elements that contain portions of encoded video, where the selection is based upon the measured streaming conditions and the description of the bitrate of the alternative stream contained within the top level data.
