In one embodiment, a method of signaling individual layers in a transport stream includes: determining a plurality of layers in a transport stream, wherein each layer includes a respective transport stream parameter setting; determining an additional layer for the plurality of layers in the transport stream, wherein the additional layer enhances one or more of the plurality of layers including a base layer and the respective layer parameter settings for the plurality of layers do not take into account the additional layer; and determining an additional transport stream parameter setting for the additional layer, the additional transport stream parameter setting specifying a relationship between the additional layer and at least a portion of the plurality of layers, wherein the additional transport stream parameter setting is used to decode the additional layer and the at least a portion of the plurality of layers.

The present disclosure relates to a network control method and a data processing system for reducing traffic in a network and reducing a processing load of an application that performs data processing.

A network connection device determines, on the basis of a manifest, an optimal location for execution of an application that processes sensor data generated by a sensor device, from among the sensor device and a device on a path in a network connected to the sensor device. The present technology can be applied to, for example, a network control method of cloud computing.

Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different content distribution network (CDN) servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

Illustrative embodiments include a method, an electronic device, and a computer program product for video processing. In the method, a first group of image frames in a first video having a first resolution is converted into a second group of image frames having a second resolution, the first resolution being higher than the second resolution; a second video having the second resolution is generated based on the second group of image frames; conversion parameters for the second video are determined based on the first group of image frames and the second group of image frames, the conversion parameters being used to convert an image frame in the second group of image frames into an image frame having a third resolution, and the third resolution being higher than the second resolution; and the conversion parameters and the second video are sent to a requester of the first video.

Systems, methods, and computer-readable media for porting locally processed media data with low latency to a remote client device via various wireless links are provided. In one example embodiment, a transceiver module may include a local network interface and a controller that may receive a client control signal from a client device over a wireless local area network via the local network interface, transmit a media control signal based on the client control signal to a media device, receive media data based on the media control signal from the media device, and transmit to the client device over the wireless local area network via the local network interface client data based on the media data and a low-latency compression technique. The receipt of the media data and transmission of the client data may be accomplished with substantially no detectable latency. Additional embodiments are also provided.

A scheduling method includes: a server receiving a first request of a first peer (P2P) node; the first request containing service content; using position information on different network hierarchies of the first P2P node and the service content to determine at least one candidate P2P node for the first P2P node; the at least one candidate P2P node can provide a service for the first P2P node; the position information being position information generated on the basis of a network topology structure; using the at least one candidate P2P node to generate a candidate P2P node information list; P2P node information in the information list representing a transmission distance between the at least one candidate P2P node and the first P2P node; and returning the information list to the first P2P node. Further disclosed at the same time are a server, a first P2P node and a computer-readable storage medium.
