Abstract:
A method for creating a coded target Continuous Presence (CP) image according to a video coding standard from a number of coded video signals including defined orders of macroblocks, each including coded video signals corresponding to a respective endpoint video image, received from endpoints participating in a multipoint video conference, the method including: decoding the coded video signals with plural decoders to generate decoded video signals; spatially mixing the decoded video signals, resulting in a number of CP images including regions respectively associated with each of the endpoint video images with a mixing unit; encoding the CP images with plural encoders; and rearranging macroblocks of the encoded CP images to create the target coded CP image with one or more re-packer units.
