For example, 120 Hz display can be favorably performed on a reception side even in the case of encoding and transmitting moving image data of 24 Hz at the frame rate of 60 Hz.

A video stream of a second frame rate larger than a first frame rate is obtained by encoding each picture constituting moving image data of the first frame rate at the second frame rate. Identification information indicating a synchronization relationship between the first frame rate and display start timing is inserted into encoded image data of each picture constituting the video stream of the second frame rate.

The video stream of the second frame rate in which the identification information is inserted is transmitted.

System for efficient recovery of node-B buffered data following MAC layer reset

A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.

Method and system for creating wide-screen picture-dominance effect in a conventional motion-picture theater
20180288379 · 2018-10-04 ·

A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, virtual reality picture-dominance effect not previously obtainable in such theaters. The invention uses a zero-gain or nominal-gain curved screen to accommodate a wide-screen presentation, and a digital projector capable of delivering fourteen foot-lamberts or more of light to the screen. It can support any theatrical aspect ratio for presentation, including 2.76:1. To eliminate image distortion, the invention uses mapping software to correct the image for the geometry of the auditorium and the shape of the screen. This correction is established for every aspect ratio displayed in the auditorium in which the invention is installed, and aspect ratios can be changed to display content with different aspect ratios during a program. The images delivered to viewers through the invention deliver the full benefit of the native aspect ratio in which they are displayed.

Recall device

A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

Apparatus and method for converting a frame rate

An apparatus and method for converting a frame rate, the method including: receiving a first video signal; extracting target frames corresponding to the first video signal, wherein the target frames include same content as original signal frames corresponding to the first video signal; generating a second video signal from the target frame; and performing a Motion Estimation and Motion Compensation (MEMC) process on the second video signal.

Video pictures pattern detection
09661261 · 2017-05-23 · ·

Some embodiments of the invention provide a media-editing application that performs frame rate conversion detection on a video. For a video that has been converted from one frame rate and format to another frame rate and format, the application detects the conversion method that has been used in the conversion of the video. Some embodiments perform this frame rate conversion detection by detecting patterns of repeating fields and/or frames in a video sequence created by the different conversion processes. Some embodiments compute (i) a frame difference value for each consecutive frames, (ii) a correlation score for the first and second fields of each frame, and (iii) a correlation score for the second field of each frame and the first field of a succeeding frame. Frame difference values are compared with each other to detect repeated frames and correlation scores are compared with each other to detect repeated fields.

One pass video processing and composition for high-definition video

A video composition model that provides a set of application programming interfaces (APIs) to set device contexts, and determine capabilities of graphics hardware from a device driver. After the model determines a configuration, the model determines input video stream states applicable to frame rates, color-spaces and alpha indexing of input video streams, interactive graphics, and background images. The model prepares the input video frames and reference frames, as well as a frame format and input/output frame index information. The input video streams, interactive graphics and background images are processed individually and mixed to generate an output video stream.

SYSTEMS AND METHODS TO CONTROL JUDDER VISIBILITY

Methods and systems for controlling judder are disclosed. Judder can be introduced locally within a picture, to restore a judder feeling which is normally expected in films. Capture time and display time of frames can be manipulated to obtain a desired amount of judder. Frames can be interpolated to obtain a film with a higher frame rate and localized control of judder.

Display apparatus and driving method thereof

A display apparatus and a driving method thereof capable of assuring reliability in frame inversion driving and improving cinema video image quality are provided. To accomplish this, a display apparatus of the embodiment replaces at least one of a plurality of frame images obtained by doubling the frame rate, with a different image before display. Specifically, the display apparatus replaces at least one of the double-speed converted plural frame images with a high-frequency emphasized image and at least one with a low-frequency component image, and displays the frame images. Furthermore, the display apparatus replaces an image at the border between cinema images with a different image before displaying.
