Abstract: A method for delivering media to a playback device including outputting first test media to be viewed by a first user. The method further includes receiving a first user input related to a first perception of the first test media by the first user and indicating a first personalized quality of experience of the first user with respect to the first test media. The method further includes generating a first personalized sensitivity profile including one or more viewing characteristics of the first user based on the first user input, and determining, based at least in part on the first personalized sensitivity profile, a first media parameter. The first media parameter is determined in order to increase an efficiency of media delivery to the first playback device over a network while preserving the first personalized quality of experience of the first user.

Abstract: A quantization parameter signalling mechanism for both SDR and HDR content in video coding is described using two approaches. The first approach is to send the user-defined QpC table directly in high level syntax. This leads to more flexible and efficient QP control for future codec development and video content coding. The second approach is to signal luma and chroma QPs independently. This approach eliminates the need for QpC tables and removes the dependency of chroma quantization parameter on luma QP.

Abstract: Methods and systems for frame rate scalability are described. Support is provided for input and output video sequences with variable frame rate and variable shutter angle across scenes, or for input video sequences with fixed input frame rate and input shutter angle, but allowing a decoder to generate a video output at a different output frame rate and shutter angle than the corresponding input values. Techniques allowing a decoder to decode more computationally-efficiently a specific backward compatible target frame rate and shutter angle among those allowed are also presented.

Abstract: Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.

Abstract: A system and method for the prediction of a thermal load for a proposed imaging procedure in view of the current thermal state for an imaging system employs a suitable software program/algorithm which determines a predicted or likely set of individual steps for a proposed imaging procedure to be performed. The system receives parameters for the particular imaging procedure to be performed and compares these parameters with information stored concerning prior performed imaging procedures to locate prior performed imaging procedures that have similar parameters to that for the proposed imaging procedure. The system utilizes the similar prior performed procedures as models of a likely set of imaging steps for the proposed procedure and estimates the heat generation produced by the models. The software program/algorithm can then determine if the entire proposed imaging procedure represented by the models can be successfully performed under the current thermal state for the imaging system.

Abstract: Methods, systems, and bitstream syntax are described for canvas size, single layer or multi-layer, scalable decoding, with support for regions of interest (ROI), using a decoder supporting reference picture resampling. Offset parameters for a region of interest in a current picture and offset parameters for an ROI in a reference picture are taken into consideration when computing scaling factors to apply reference picture resampling. Syntax elements for supporting ROI regions under reference picture resampling are also presented.

Abstract: There is described a system for providing an interface with activity recommendations by monitoring user activity in which user data relating to a user is received at a user device. The user data comprises at least image data, text input, biometric data, and audio data, and may have been captured using one or more sensors on the user device. The user data is processed using at least: facial analysis; body analysis; eye tracking; voice analysis; behavioural analysis; social network analysis; location analysis; user's activities analysis; and text analysis. Based on the user data, one or more states of one or more cognitive-affective competencies of the user may be determined. An emotional signature of the user is determined, based on the one or more states of the one or more cognitive-affective competencies of the user. Based on the emotional signature, one or more recommendations for improving the emotional signature may be recommended.
