Patent number: 8411811Abstract: In a method for recovery of a clock from a received digital data stream and an apparatus for recovering a clock from a received digital data stream, phase-shifted clock signals are generated from a receiver's clock. After selecting one of the phase-shifted clock signals, two other phase-shifted clock signals are determined. Depending on sample values taken at rising/falling edges of the three selected phase-shifted clock signals, counter values are increased and compared. The selection of phase-shifted clock signals and the steps of sampling the input digital data stream, comparing the values and increasing counter values, if required, are repeatedly performed until the comparison result of the counter values indicates that one of the latter determined phase-shifted clock signals strobes the received digital data stream in the center of a bit period.Type: GrantFiled: July 21, 2010Date of Patent: April 2, 2013Assignee: STMicroelectronics Pvt.

Patent number: 8395991Abstract: Systems and methods are for implementing a NSV2SV converter that converts a non-scalable video signal to a scalable video signal. In an implementation, a non-scalable video signal encoded in H.264/AVC standard is decoded and segmented into spatial data and motion data. The spatial data is resized into a desired resolution by down-sampling the spatial data. The motion data is also resized in every layer, except in the top layer, of a scalable video coding (SVC) encoder by using an appropriate measure. Further, the motion data is refined based on the resized spatial data in every layer of the SVC encoder. The refined motion data and the down-sampled spatial data are then transformed and entropy encoded in the SVC standard in every layer. The SVC encoded output from every layer is multiplexed to produce a scalable video signal.Type: GrantFiled: September 14, 2009Date of Patent: March 12, 2013Assignees: STMicroelectronics PVT.
