Disclosed are a transmitting method, a receiving method, a transmitting device and a receiving device for high-definition video data. The transmitting method comprises the follows. High-definition video data with different color space formats is obtained by a transmitting device via an input interface. processing, by the transmitting device, the high-definition video data into a data packet; transmitting, by the transmitting device, the data packet to a first communication module with the transmission rate not less than a first threshold. The first communication module is configured to transmit the data packet. By the adoption of the disclosure, the transmitting device can transmit the high-definition video data to a receiving device through the first communication module and based on a network cable or an optical fiber, so that lossless high-definition video transmission with ultra-low latency can be realized.

Embodiments described herein provide systems and methods for sharing encoder output of video streams. In a particular embodiment, a method provides determining video profiles for each of a plurality of devices. The method further provides determining if two or more of the video profiles are similar by determining if parameters associated with each video profile differ by less than a threshold value. The method further provides transmitting a video stream encoded in a single format to the devices if they have similar profiles and transmitting video streams encoded in different formats to the devices if they do not have similar profiles.

Several techniques for video encoding and video decoding are described. One example method includes performing a conversion between a subpicture in a video picture of a video and a bitstream of the video according to a rule. The rule specifies that multiple syntax elements are used to specify usage of a reference picture resampling tool.

A method and a system for virtual reality, augmented reality, mixed reality, or 360-degree Video environment is disclosed. The system receives Video Streams associated to audio and video scenes to be reproduced and Audio Streams associated to audio and video scenes to be reproduced. There are provided a Video decoder which decodes signal from the Video Stream for the representation of the audio and video scene; an Audio decoder which decodes signal from the Audio Stream for the representation of the audio and video scene to the user; and a region of interest processor deciding, based e.g. on the user's viewport, head orientation, movement data, or metadata, whether an Audio information message is to be reproduced. At the decision, the reproduction of the Audio information message is caused.

A system for transcoding a digital video stream using a transcoder includes receiving a digital video stream that includes an input video stream and extracting a first set of presentation time stamps from the input video stream which are stored in a table. The system transcodes the input video stream including the first set of presentation time stamps from an initial set of characteristics to a modified set of characteristics including a second set of presentation time stamps that are different from the first set of presentation time stamps. The system processes the second set of presentation time stamps of the transcoded video stream to determine if the second presentation time stamps include jitter, and based upon determining the second set of presentation time stamps include jitter modifying the second set of presentation time stamps based upon the first set of presentation time stamps in the table.

A method for providing media content within a media distribution network. The method comprises transforming source media content into an interim format, thereby providing transformed content. Furthermore, the method comprises storing the transformed content on at least one core storage unit. In addition, the method comprises receiving a request for the source media content from a client. The method further comprises encoding the transformed content or intermediate coded content derived therefrom into encoded content suitable for transmission over a core network and/or an edge network, as well as sending the encoded content via the core network and/or the edge network to the client.

An acquisition unit capable of providing more flexible services includes an acquisition unit that acquires a first stream; a transformer that transforms a first picture included in the first stream into a second picture, the first picture being irreversibly encoded, the second picture being reversibly encoded; and an output unit that outputs a second stream including the second picture.

Various arrangements of a local cloud system for providing television services are presented. A facility cloud host system may have a content service provider interface that is used to receive live television channel streams from a television content service provider. The local cloud system may have a transcoder that transcodes the live television channels into a format to be transmitted locally to client devices. The local cloud system may provide access to recorded content from a remote master cloud host.

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.

This application relates to a picture sharing method, a computer device, and a storage medium. The method includes: receiving a picture compressed in a first compression manner; obtaining characteristic information of the picture; compressing the picture in a second compression manner in a case that the characteristic information meets a compression trigger condition, to obtain a compressed picture; receiving a picture download request for the picture, wherein the second compression manner has a higher compression ratio than the first compression manner; and returning the compressed picture in response to the picture download request. The solutions of this application reduce a network bandwidth occupied in a picture feedback process.
