摘要： A method, apparatus, and system for detecting DeepFake videos, includes an input device for inputting a potential DeepFake video, the input device inputs a sequence of video frames of the video, and processing circuitry. The processing circuitry detects faces frame by frame in the video to obtain consecutive face images, creates UV texture maps from the face images, inputs both face images and corresponding UV texture maps, extracts image feature maps, by a convolution neural network (CNN) backbone, from the input face images and corresponding UV texture maps and forms an input data structure, receives the input data structure, by a video transformer model that includes multiple encoders, and computes, by the video transformer model, a classification of the video as being Real or Fake. A display device plays back the potential DeepFake video and an indication that the video is Real or Fake.

摘要： Methods and systems are provided for integrated channel and/or band stacking solutions. A plurality of signals may be received, such as via a signal receiver, with each of the received signals being different from remaining ones of the plurality signals. At least two received signals may be processed, such as via one or more processing circuits, and an output signal may be generated based on the processing of the at least two received signals. The output signal may include only one or more portions from each of the at least two signals, with the one or more portions being stacked within the output signal. The stacking of the one or more portions from the at least two signals may include applying channel equalization, with the channel equalization including equalizing power of a plurality of sub-components of a frequency band corresponding to the one or more portions.

摘要： Embodiments of the present disclosure disclose a channel change method and a related apparatus. The channel change method includes: receiving a live stream of a first channel, where the live stream of the first channel includes N media file sets; separately encoding the live stream of the first channel in different coding manners, to generate both a main stream and a sub stream; and generating a playlist of the first channel according to channel information of the first channel, coding information of the main stream, and coding information of the sub stream. The playlist instructs the client to perform channel change according to the main stream and the sub stream in response to that a client sends a channel change instruction.

摘要： A method for selecting a tile amongst a set of tiles associated with a multimedia content divided into a plurality of tile segments requested by a terminal is described. The multimedia content that is divided into a plurality of tile segments, includes obtaining a next position of a viewport of the terminal at the expiration of a current tile segment based on an estimation of a trajectory of the viewport; identifying one or several tiles amongst the set of tiles comprising at least the viewport at the next position; determining at least one processing parameter depending on at least the center of the identified tile and the next position of the viewport; and selecting an identified tile for which the determined processing parameter meets a selection criterion.

摘要： Systems and methods are disclosed for delivering video content over a network, such as the Internet. Videos are identified and pre-processed by a web service and then separated into a plurality of segments. Based on user interests, video segments may be pre-fetched and stored by a client associated with a user. Upon receiving a selection from a user to play a video, the first video segment may begin playing instantaneously from a local cache. While the first video segment plays, subsequent video segments are transmitted from the web service to the client, so that the subsequent video segments will be ready for viewing at the client when playback of the first video segment has finished.
