Systems, methods, and media are disclosed for propagating video streams based on geographical proximity and required transmission latency. A first video stream is received from a first presenting client device at a first origin video server connected to at least one other origin video server forming a mesh network. The first video stream is relayed to at least a second origin video server from the first presenting client device. The first video stream is transmitted from the second origin video server to an edge video server. The first video stream is received from the second origin video server by one or more edge video servers. The first video stream is broadcast to a plurality of participant client devices. A second video stream is received from a second presenting client device. The second video stream is transmitted via the second origin video server to the plurality of participant client devices.

Techniques for neutralizing malicious malware embedded in a media item being sent to a user equipment (UE) are discussed herein. A network device may receive (e.g., intercept) a medial file in transit via a wireless communication network being sent to a UE. The media file may include some type of perceptible content (e.g., audio, video, image data, etc.) as well as malware embedded in the media file. The network device may generate a transcoded media file based on the received media file that includes the perceptible content while neutralizing the malware.

A method and system for processing media content by at least one processor is provided. The method includes: obtaining a list of function repositories, each function repository storing one or more functions for processing the media content, obtaining a descriptor identifying a location of each of the function repositories identified in the list of function repositories, selecting a function repository, from among the function repositories, according to a criterion, and processing the media content using a function included in the selected function repository.

A method of network-based media processing (NBMP) can include receiving a function description of a media processing function from a function repository at a workflow manager in an NBMP system. The function description can include a configuration descriptor providing configuration information of parameters for the media processing function. The parameters can have logical relationships represented by a parameter representation graph constructed according to a set of rules. The media processing function can be instantiated as a media processing task that is part of a workflow. The media processing task can be configured based on the configuration information of the parameters in the configuration descriptor.

Systems and methods for mirroring and transcoding media content are provided. In some embodiments, media content stored on a user equipment device is mirrored on a remote server, and the mirrored copy is transcoded and provided to other user devices in a media content format that is appropriate for the user devices. By so doing, the present invention not only provides a convenient and easy way for users to backup media content and access the media content from virtually any device, but also reduces the complexity and costs associated with maintaining reliable and consistent access to media content across various user devices.

The present technology relates to a transmission device, a reception device, a transmission system, and a transmission method capable of improving transmission efficiency of subdata added to main data.

A transmission device includes a frame sequence number setting unit that, on the basis of a frame number indicating an order of a subframe in a main frame, assigns to the subframe a frame sequence number indicating an order of the subframe in a frame sequence including a plurality of the subframes, and a multiplexing unit that arranges a data packet at a predetermined position in the subframe on the basis of the frame sequence number. The present technology can be applied to a CCU, for example.
