Abstract:
1. A method for encoding a sequence of video pictures, said method comprising: encoding a first order value for a first video picture, a second order value for a second video picture, and a third order value for a third video picture, wherein each order value is representative of a position of a video picture in a sequence of video pictures; computing a particular value based on a first order difference value and a second order difference value, wherein (i) the first order difference value is representative of a difference between the third order value and the first order value and (ii) the second order difference value is representative of a difference between the second order value and the first order value; computing a motion vector for the second video picture based on the particular value and a motion vector for the third video picture; encoding the first, second, and third video pictures, wherein the second video picture is encoded by using the computed motion vector; and storing the encoded first video picture, the encoded second video picture, the encoded third video picture, the encoded first order value, the encoded second order value and the encoded third order value in a bitstream.
