摘要： A method (800, 820 ), device (900 ) and program product for compression video information is presented. The method comprises the following steps: projecting (803 ) points of a next image to a three-dimensional space using camera parameters and depth map and projecting (805 ) projected points from the three-dimensional space to reference image surface, thereby obtaining motion vectors for estimating changes between the next image and the reference image.

摘要： A method and a device for transferring service data stream such as compressed video signal including both non-predictive and predictive data frames of a common data type. Larger non-predictive frames are transmitted on demand only (1014) upon occurrence of a triggering event (1004, 1006). Otherwise, solely predictive frames of smaller size are transferred (1008) to cut down the transmission delay.

摘要： According to an example embodiment, an apparatus (101) for communication with another apparatus (102-k) over a packet-switched network (103) is provided, the apparatus (101) comprising a transport protocol portion is arranged to cause the apparatus (101) to carry out at least the following: transmit, to the other apparatus (102-k, 102-m, 102-n), user data in a sequence of data blocks having respective sequence numbers assigned thereto, receive, from the other apparatus (102-k, 102-m, 102-n), acknowledgements blocks acknowledging reception of at least some of said data blocks, retransmit, to the other apparatus (102-k, 102-m, 102-n), those ones of said data blocks that are not acknowledged by the other apparatus (102-k, 102-m, 102-n), enter a congestion avoidance state in response to a predefined amount of said data blocks not being acknowledged by the other apparatus (102-k, 102-m, 102-n), wherein the apparatus (101) comprises a complementary transport protocol portion arranged to: provide the transport protocol portion with information that indicates acknowledgement of all data blocks up to one having a first reference sequence number assigned thereto, and selectively cause the apparatus (101) to transmit, to the other apparatus (102-k, 102-m, 102-n), a control block instructing the other apparatus (102-k, 102-m, 102-n) to ignore any unreceived data blocks having assigned thereto a sequence number that is smaller than a second reference sequence number.

摘要： A method and a device for supplying a decoder with data stream such as compressed video signal including both non-predictive and predictive data frames of a common data type. A device comprising a decoder for service data is provided with (1012, 1020) a specific frame that is a predictive frame indicating substantially no changes in the service data in relation to a possible previous service data frame supplied. A service data buffer is monitored (1014) and in case it's at least near an underflow condition according to a number of predetermined criteria (1016), the decoder is fed with the specific frame in order to prevent the decoder from being disturbed due to a lack of timely provided proper input data (1018).
