Problems solved by technology

However, the processing and transmission of the culled object image has the potential to pollute the black areas of the image with erroneous video signals, producing artifacts such as speckles, low brightness, and colored artifacts that impair realistic telepresence experience

Embodiment Construction

[0062] figure 1 Shown is a telepresence system according to an embodiment of the invention comprising a first location 1 and a second location 2 remote from the first location 1, wherein an object displayed in the form of a Pepper's Ghost is photographed at the first location , producing a Pepper's ghost of the object at the second position 2. Data is communicated between the first location 1 and the second location 2 via the two-way communication link system 20 . The two-way communication link system is for example the Internet or Multi-Protocol Label Switching (MPLS), both of which may use a virtual private network or the like.

[0063] refer to figure 1 , 3 , 7 and 8, a first location 1, which may be a movie studio, includes a camera 12 for capturing an object 104, such as an actor or a meeting participant, to project it at location 2 in the form of a Pepper's ghost. In an interactive system where the object 104 interacts with a person at position 2, the first position ...

Abstract

A codec comprising a video input (33) for receiving a continuous video stream, an encoder (42) for encoding the video stream to result in an encoded video stream, a video output (37) for transmitting the video stream and switching means (39). The switching means is for switching the encoded video stream during encoding between a first mode, in which the video stream is encoded in accordance with a first encoding format, to a second mode, in which the video stream is encoded in accordance with a second encoding format. The invention also relates to a corresponding codec for decoding the video stream. In another aspect the invention concerns a processor for identifying an outline of a subject within a video image.

Description

technical field [0001] The present invention relates to video processing, and in particular, but not exclusively, to video codecs and video processors for use in telepresence systems to produce "real-time" Pepper's Ghosts and / or to cull from the background behind a subject (keyout ) from the image of the object (hereinafter referred to as "culled object image"). Background technique [0002] In a conventional telepresence system, a video image of an object captured at one location, complete within its background, is transmitted to a remote location via, for example, the Internet or a Multiprotocol Label Switching (MPLS) network, the objects and background An image is projected or otherwise displayed at the remote location in the form of a Pepper's Ghost. The transmission can be performed such that a "real-time" image, or at least a pseudo-real-time image, can be produced at the remote location to "telepresence" the subject at the remote location. The transmission of the vi...
