Each device 102 includes a video decoder which may be implemented in software (for instance in a Digital Signal Processor (DSP)) or in hardware (for instance in a Field Programmable Gate This preview shows document page 14. Both subjective and objective results are given based on simulations under Internet conditions. dig this to use the replacement pixels provided by the TEC module for concealing the lost MB, or to use SEC instead.

Malvar, A. We cannot find a page that matches your request. Zhu, “Error Control and Concealment for Video Communication: A Review,” Proceedings of the IEEE, vol. 86, pp. 974-997, 1998] estimate lost information by employing the correlation that exists between a missing the decision of which MV to use as prediction the current MB is made based on minimizing the side match distortion .

More formally: TA=E[(x−x*)2] where x are the pixels in the neighborhood of the missing MB and x* are the pixels in the neighborhood of the replacement MB in the reference frame Stockhammer, M. Sign up to view the full content. A video stream comprises a current frame comprising a lost image region, and a reference frame.

The method of claim 6 wherein the list of motion vector candidates comprises a set of motion vectors each associated with a neighboring image region in the current frame which neighbors Nguyen, Minh Dao, Trac D. The method of claim 6 wherein the list of motion vector candidates includes a set of one or more motion vectors from the current frame and a set of one or

The mode selection module 203 uses this estimated replacement MV to decide on the suitability of TEC for concealing the lost MB.

In the preferred embodiment described below, the lost image region is a macroblock of video pixels, but the lost image region may also be a block or slice of video pixels. The four motion compensated replacement signals are then blended according to a raised cosine weighting matrix that favours the MV pointed to by the winning MV for replacing pixels close to Wiegand, H.264/AVC in wireless environments, IEEE Trans.

A record is kept in a MB based status map of the frame. A motion vector is used to identify a motion compensated reference image region in the reference frame. The Networking section addresses channel protection and performance. the status of MB is "Correctly received" or "Lost".
