Method and apparatus for compositing compressed video data |
摘要 |
Inverse motion compensating devices are used to transform motion compensated transform domain video signals to corresponding transform domain video signals. A compositing mechanism receives the transform domain video signals from the inverse motion compensating devices and performs transform domain video compositing operations directly on the transform domain video signals. The compositing operations result in a single composited signal incorporating each of the transform domain video signals. The single composited signal may be encoded for motion compensation to generate a single motion compensated transform domain video signal suitable for transmission. After transmission, inverse transform domain operations and inverse motion compensation operations may be performed to reconstruct the composited signal. The composited signal may then be projected on a video display device. |
