    • The present invention relates to a video encoding device (10, 10', 10'') and method for encoding video data and to a corresponding video decoding device (60, 60') and method. To preserve PPG relevant information after encoding without requiring a large amount of additional data for the video encoder output stream, the proposed video encoding device comprises a selection unit (20, 20') for selecting a region of interest (101) in input video data (100) providing a strong PPG signal, a first encoding unit (30,30') for encoding said selected region of interest (101) of said input video data (100) according to a predetermined encoding scheme with a first setting of the encoding to preserve PPG-relevant information in the encoded region of interest, a second encoding unit (40, 40') for encoding remaining parts (103) of said input video data (100) according to said predetermined encoding scheme with a second setting of the encoding, and an encoder combination unit (50) for combining the encoded region of interest (102) and the encoded remaining parts (104) of said input video data into an encoder output video stream (105).

    • The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (26) derivable from electromagnetic radiation (14) emitted or reflected by an object (12) is received. The data stream (26) comprises a continuous or discrete time-based characteristic signal ( p ; 98) comprising at least two main components (92a, 92b, 92c) related to respective complementary channels (90a, 90b, 90c) of a signal space (88). The characteristic signal ( p ; 98) is mapped to a defined component representation ( b , h , s , c ; T , c ) under consideration of a substantially linear algebraic signal composition model so as to specify a linear algebraic equation. The linear algebraic equation is at least partially solved under consideration of an at least approximate estimation of specified signal portions ( b , h , s ). Consequently, an expression highly indicative of the at least one at least partially periodic vital signal (20) can be derived from the linear algebraic equation.

    • The invention describes a method of determining the distance (d12) between two loudspeakers (L1, L2), wherein the method comprises the steps of providing a test signal (N), combining the test signal (N) with a sound signal (S) to give a combined signal (SN) in which the test signal is imperceptible to a listener (4), and issuing the combined signal (SN) by means of a first loudspeaker (L1). The combined signal (SN) is detected by a detecting means (M2) associated with the second loudspeaker (L2) and processed to obtain an acoustic impulse response (IR), which is used to determine the distance (d1,2) between the first loudspeaker (L1) and the second loudspeaker (L2). The invention further describes a system (1) for determining the distance (d1,2) between two loudspeakers (L1, L2) and an acoustic sound system, comprising a number of loudspeakers (L1, L2, . . . , Lk) for reproduction of multi-channel sound, and a system (1) for determining the distances (d1,2, d2,3, . . . , dk-i,k) between the loudspeakers (L1, L2, . . . , Lk) in order to automatically configure the loudspeakers (L1, L2, . . . , Lk) for that acoustic sound system.
