Secured communications with display device
Techniques are provided herein for secure display device communications. In one example, a video communications device provides, to a display device over a first connection, communication information that enables the display device to contact a server over a second connection. The video communications device further provides, to the display device over the first connection, a command configured to initiate an interaction with the server. The server obtains, from the display device over the second connection, a message initiating the interaction in response to the command based on the communication information.
Conference device, method of controlling conference device, and computer storage medium
The present disclosure provides a conference device, a method of controlling the conference device, and a computer storage medium. The conference device includes a display, an image sensor, a holographic projector, and a controller configured to identify, by using an image data from the image sensor, a modification action performed at a target location for a holographic image projected by the holographic projector, modify holographic projection data based on the modification action, and convert modified holographic projection data into modified two-dimensional imaging data.
Video frame pulldown based on frame analysis
The described technology is directed towards generating a new video image sequence (e.g., for playback at 30 frames per second) based on an existing video image sequence (e.g., originated for playback at 24 frames per second). The technology is based on processing frames, e.g., adjacent pairs of frames in a four-frame sequence, to obtain candidate frames for selecting a similar candidate frame to insert into the original sequence to create the new sequence (e.g., a five-frame sequence). Aspects include selecting a repeated frame to insert or creating a new frame from existing frames to insert, to generate the new sequence based on a difference/scoring comparison.
Method of MEMC and related video processor
A motion estimation method for a video processor includes steps of: calculating frame difference between a current input frame and a previous input frame; comparing the frame difference and a threshold to generate a comparison result; if the comparison result indicates the frame difference less than the threshold, determining whether a first block of the current input frame is a mixed block according to a block difference that indicates a difference between the first block and a block of the previous input frame at the same position; generating at least one temporal motion vector candidate for the first block; modifying the temporal motion vector candidate according to a current position difference value of video part in the current input frame when the first block is determined as the mixed block; and determining a motion vector for the first block from multiple motion vector candidates including the temporal motion vector candidate.

ELECTRONIC APPARATUS AND CONTROLLING METHOD THEREOF
An electronic device is provided. The electronic apparatus includes a preprocessor configured to determine a repeated image frame in an image frame and perform an inverse conversion image processing only on one image frame in each image frame set consisting of the repeated image frame, and a frame rate converter configured to perform a frame rate conversion by using the image frame output from the preprocessor.
VIDEO FRAME PULLDOWN BASED ON FRAME ANALYSIS
The described technology is directed towards generating a new video image sequence (e.g., for playback at 30 frames per second) based on an existing video image sequence (e.g., originated for playback at 24 frames per second). The technology is based on processing frames, e.g., adjacent pairs of frames in a four-frame sequence, to obtain candidate frames for selecting a similar candidate frame to insert into the original sequence to create the new sequence (e.g., a five-frame sequence). Aspects include selecting a repeated frame to insert or creating a new frame from existing frames to insert, to generate the new sequence based on a difference/scoring comparison.

Frame interpolation method and related video processor
A frame interpolation method for a video processor includes the steps of: determining whether a first input frame is received following a long-term cadence; generating interpolated frames by applying phase coefficients in a regular phase table corresponding to the long-term cadence when the first input frame is received following the long-term cadence; and generating interpolated frames by applying phase coefficients in a bad edit phase table corresponding to a bad edit cadence when the first input frame is received without following the long-term cadence.
