A transmitting device for generating a plurality of encoded portions of a video to be transmitted to a receiving device over a network configured to: receive an error message over a feedback channel from the receiving device indicating at least one of said plurality of encoded portions that has been lost at the receiving device; encode a recovery portion responsive to said receiving said error message; and transmit said recovery portion to the receiving device over said network; wherein said error message includes information pertaining to a decoded portion successfully decoded at the receiving device and said recovery portion is encoded relative to said decoded portion.

Video coding

A receiving apparatus comprises a receiver for receiving a video signal, an output for outputting the video signal to a screen, storage device or further terminal; and a concealment module for applying a concealment algorithm to a lost area of the video signal. The concealment module is configured to determine an estimate of concealment quality selectively directed toward a region of interest within the area in question, and based on this estimate to determine whether or not to apply the concealment algorithm.

Conditional concealment of lost video data

According to one embodiment, the x-ray apparatus includes an x-ray source adapted to emit an x-ray beam and a detector adapted to receive the x-ray beam of the x-ray source. The x-ray source is adapted to be moved in relation to a first portion of the x-ray apparatus and the detector is adapted to be moved in relation to a first portion of the x-ray apparatus. A control unit controls the movement of the x-ray source and detector. The x-ray source and the detector are adapted to rotate in relation to a first portion of the x-ray apparatus. Further, the x-ray beam is directed essentially towards the detector during the movement of the x-ray source and the detector.

Field limiting device synchronized with scan motion

An encoder comprising an encoding module and an adaptation module. The encoding module is configured to encode video in at least one region-of-interest and outside the region-of-interest. The encoding comprises quantization, and the encoding module is operable to apply a difference in quantization granularity between the encoding inside and outside the region-of-interest. The adaptation module is configured to determine at least one metric representative of a difference in benefit of the quantization inside and outside the region-of-interest, and to adapt the difference in quantization granularity in dependence on this metric.

Region-of-interest aware video coding

According to one embodiment, the x-ray apparatus comprises an x-ray source adapted to emit an x-ray beam, a detector adapted to receive the x-ray beam of the x-ray source, wherein the x-ray source is adapted to be moved in relation to a first portion of the x-ray apparatus, wherein the detector is adapted to be moved in relation to a first portion of the x-ray apparatus, the x-ray apparatus further comprising a control unit for controlling the movement of the x-ray source and detector, wherein the x-ray source and the detector are adapted to rotate in relation to a first portion of the x-ray apparatus, wherein further the x-ray beam is directed essentially towards the detector during the movement of the x-ray source and the detector.

Adapting a scan motion in an x-ray imaging apparatus

A user terminal for participating in video calls comprises: an encoder having a frame size, being the size in pixels at which it encodes frames of video; and a pre-processing stage which supplies a sequence of frames to the encoder at that frame size, each frame comprising at least an image region representing a source video image at a respective moment in time. The pre-processing stage is configured to supply at least some of the frames to the encoder in a modified form, by resizing the source video image to produce the image region of each modified frame with a size smaller than the frame size of the encoder, and combining with a border region such that the modified frame matches the frame size of the encoder. The encoder encodes the frames at the frame size and transmits them to a receiving terminal as part of a live video call.
