The present disclosure provides video processing methods, apparatuses and systems. The method includes: obtaining a to-be-processed video, where the to-be-processed video is obtained by performing feature removal processing for one or more objects in an original video; obtaining a feature restoration processing request for one or more to-be-processed objects; according to the feature restoration processing request for the one or more to-be-processed objects, obtaining feature image information corresponding to the one or more to-be-processed objects, where the feature image information for one of the one or more to-be-processed objects includes pixel position information of all or part of features for the one of the one or more to-be-processed objects in the original video; according to the feature image information for the one or more to-be-processed objects, performing feature restoration processing for the one or more to-be-processed objects in the to-be-processed video.

An imaging system including an imaging device 501 and a recording server 502 communicatively connected to the imaging device 501, wherein the imaging device 501 includes an imaging unit 503 that generates a video with a plurality of resolution, a dividing unit 504 that performs a division process of dividing the video generated by the imaging unit 503 into one or a plurality of tile areas and generates a tile image, and a transmission unit 506 that transmits the video to the recording server 502, wherein the recording server 502 includes a division control unit 507 that outputs an instruction to change a division method for the division process to the imaging device according to a designation frequency of an area designated on the video transmitted from the imaging device 501.

The present invention relates to a method for dynamic image content replacement in a video stream comprising generating a set of key image data (K) comprising a sequence of at least two different key images (K1, K2), periodically displaying said set of key image data (K) on a physical display, generating at least a first original video stream (O1) of a scene which includes said physical display by recording said scene with a camera, wherein said at least one video stream (O1) comprises key video frames (FK1, FK2), captures synchronously with displaying each of said at least two different key images (K1, K2) of said set of key image data (K) on said physical display, generating a mask area (MA) corresponding to an active area of said physical display visible in said key video frames from differential images (AFK) obtained from consecutive key video frames (FK1, FK2), generating at least one alternative video stream (V) by inserting of alternative image content (I) into the mask area (MA) of an original video stream, and broadcasting at least said at least one alternative video stream.

A method is provided for displaying an immersive video content according to eye movement of a viewer includes the steps of detecting, using an eye tracking device, a field of view of at least one eye of the viewer, transmitting eye tracking coordinates from the detected field of view to an eye tracking processor, identifying a region on a video display corresponding to the transmitted eye tracking processor, adapting the immersive video content from a video storage device at a first resolution for a first portion of the immersive video content and a second resolution for a second portion of the immersive video content, the first resolution being higher than the second resolution, displaying the first portion of the immersive video content on the video display within a zone, and displaying the second portion of the immersive video content on the video display outside of the zone.

Systems and methods are provided for obtaining a set of images representing a view of a geographic region to be compressed, the set of images including a first image and a second image. A first image file can be generated based on the set of images, wherein the first image is encoded in a first color channel associated with the image file, and wherein the second image is encoded in a second color channel associated with the image file. A video file can be generated based at least in part on the image file. The video file can be provided to a client device over one or more computer networks.

Embodiments provide for improved stream generation. A target average bitrate (TAB) segment is generated by encoding a first segment, of a plurality of segments in a video, using a first maximum average bitrate (MAB) of a plurality of MABs specified in an encoding ladder. An intermediate average bitrate (IAB) segment is generated by encoding the first segment using a first intermediate bitrate, wherein the first intermediate bitrate is lower than the first MAB. Upon receiving a request for the first segment at the first MAB, the IAB segment is output based at least in part on determining that a first quality score of the IAB segment is within a predefined tolerance of a second quality score of the TAB segment.

Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.

The present disclosure relates to an image processing device and an image processing method for generating a celestial sphere image such that the pixels near the poles of the sphere are kept from increasing in density when the image is mapped to the sphere surface.

An encoder encodes, with respect to an omnidirectional image generated by equidistant cylindrical projection to include a top image, a middle image, and a bottom image in a vertical direction, the middle image into an encoded stream at a high resolution, and the top image and the bottom image into encoded streams at a resolution lower than the high resolution. This disclosure is applicable to image display systems, among others.

Portion- or tile-based video streaming concepts are described.

One variation of a method includes: rendering a home screen of an ad stream viewed on a display of a streaming device accessed by a user, the home screen including an image player located in a first subregion of the home screen and a set of icons selectable by the user, each icon corresponding to a video advertisement loaded within the image player; in response to detecting a first user input proximal a first icon, reconfiguring the image player to a second subregion of the home screen and triggering playback of a first video advertisement within the image player; and, during playback of the first video advertisement, in response to receiving a second user input proximal the first icon, reconfiguring the image player to a third subregion of the home screen, activating an audio stream corresponding to the first video advertisement, and continuing playback of the first video advertisement.
