In the examples, a location in the media repository may be assigned to the media file. A media file address in a blockchain platform may be assigned to the media file. Metadata including the assigned location in the media repository and the assigned media file address in the blockchain platform may be added to the media file. A media file hash value may be generated by applying a hash function to the media file including the metadata. The media file hash value may be included in a message and uploaded to the assigned media file address in the blockchain platform as a transaction in the blockchain. An indication that the media file is uploaded to the media repository may be delivered to a subscriber device from which the media file was received. | 2021-02-04 |
| 20210037271 | CROWD RATING MEDIA CONTENT BASED ON MICRO-EXPRESSIONS OF VIEWERS - In some examples, a computing device initiates playback of media content on a display device. The computing device receives one or more images from a camera having a field of view that includes one or more viewers of the display device. The computing device may analyze at least one of the images and determine, based on the analysis, a micro-expression being expressed by at least one of the viewers. The computing device may determine a sentiment based on the micro-expression. A timestamp derived from the one or more images may be associated with the sentiment and sent to a server to create a sentiment map of the media content. If the sentiment matches a pre-specified sentiment then the computing device may skip playback of a remainder of a current portion of the media content that is being displayed and initiate playback of a next portion of the media content. | 2021-02-04 |
| 20210037272 | CONTENT DISTRIBUTION AND MOBILE WIRELESS MESH NETWORKS - According to one configuration, a wireless base station has access to a cache (repository) that stores a stream of content including multiple segments of content. The cache stores (caches) a first segment of content from the received stream of content. The first segment of content is cached in the repository for a window of time during which the first segment of content is temporarily available from the wireless base station. In response to receiving a respective request from each mobile communication device in a group of multiple mobile communication devices requesting the first segment of content during the window of time, a wireless base station communicates the first segment of content from the cache to each mobile communication device in the group. | 2021-02-04 |
| 20210037273 | COLLABORATIVE VIDEO STITCHING - Methods and systems of creating a collaborative video for a recipient are disclosed. A video stitching server may receive a collaborative video request from a collaborative video application running on an initiator's mobile device. The video stitching server may store the collaborative video request in a folder that has an identifier. The identifier may be provided to potential contributors. The video stitching server may receive contributor video information—including contributor videos and the identifier—from contributors' collaborative video applications and may store the contributor videos in the folder based on the identifier. The video stitching server may then stitch together at least two videos stored in the folder to create a collaborative video and may deliver the collaborative video to the collaborative video application miming on a recipient's mobile device. | 2021-02-04 |
| 20210037274 | SYSTEMS AND METHODS FOR CORRECTING ERRORS IN CAPTION TEXT - Systems and methods are described to address shortcomings in conventional systems by correcting an erroneous term in on-screen caption text for a media asset. In some aspects, the systems and methods identify the erroneous term in a text segment of the on-screen caption text, and identify one or more video frames of the media asset corresponding to the text segment. The systems and methods further identify a contextual term related to the erroneous term from the one or more video frames. By accessing a knowledge graph, the systems and methods identify a candidate correction based on the contextual term and a portion of the text segment. Lastly, the systems and methods replaces the erroneous term with the candidate correction. | 2021-02-04 |
| 20210037275 | SYSTEM AND METHOD FOR TRANSFERRING LARGE VIDEO FILES WITH REDUCED TURNAROUND TIME - Embodiments of the present disclosure provide methods, systems and computer program products for transfer of video signals at a destination with reduced turnaround time. According to one embodiment, a method includes performing transfer of a series of video chunks of a video signal, each video chunk of the series of video chunks comprising a sequence of video frames, wherein for each video chunk, one or more processors perform a processing cycle comprising: receiving the sequence of video frames from a source; processing the received sequence of video frames to generate a processed sequence of video frames, wherein receiving of a consecutive video chunk of the series of video chunks comprising a consecutive sequence of video frames is initiated simultaneously while initiating said processing of the received sequence of video frames; and transmitting the processed sequence of video frames for consumption at a destination. | 2021-02-04 |
| 20210037276 | METHODS AND SYSTEMS FOR LOW LATENCY STREAMING - Methods and systems are described for low latency streaming. A computing device may receive a chunk of content. The computing device may determine whether a transmission duration of the chunk of the content satisfies a threshold. The computing device may determine a bitrate based on the transmission duration satisfying a threshold. | 2021-02-04 |
| 20210037277 | METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING BROADCAST SERVICE IN HYBRID BROADCAST SYSTEM ON BASIS OF CONNECTION OF TERRESTRIAL BROADCAST NETWORK AND INTERNET PROTOCOL NETWORK - The present invention relates to a device for receiving a hybrid broadcast service and a method for transmitting the same. The device for receiving a hybrid broadcast service, according to one embodiment of the present invention, comprises: a first reception unit for receiving a first broadcast signal transmitted through a first network; a second reception unit for receiving a second broadcast signal transmitted through a second network, wherein the broadcast signal includes a service information table; a signaling information processing unit for extracting the service information table from the broadcast signal, wherein the service information table includes a component identifier descriptor for signaling information for identifying each of a plurality of components constituting one broadcast service, the component identifier descriptor including identification information; and an audio/video processing unit for acquiring the broadcast service including the plurality of components by using the component identification information, and decoding and reproducing the acquired broadcast service. | 2021-02-04 |
