Benefits of technology

[0008] It is therefore an object of the present invention to provide an improved and simplified process of applying transition effects when displaying pictures by using the motion compensator in the DVD players.
[0009] The pictures stored in the DVD audio disk are encoded as MPEG Intra-Pictures (I-picture). Therefore, during the decoding of these still pictures, the motion compensator in the DVD player is idle. It is an object of the present invention to apply transition effects for displaying pictures by the idle motion compensator with the virtual picture function without the need of any excessive CPU loading or any additional dedicated hardware. Hence, the cost of the hardware can be substantially reduced and the hardware utilization of motion compensator is increased as well.

Problems solved by technology

Therefore, during the decoding of these still pictures, the motion compensator in the DVD player is idle.

Embodiment Construction

[0022] The bit-stream of the MPEG (Moving Picture Coding Experts Group) video includes a series of I pictures (Intra-coded pictures),. P pictures (forward Predictive pictures), and B pictures (Bi-directionally predictive-coded pictures). I pictures are encoded as stand-alone still image. P pictures are encoded referring to the nearest I or P pictures by forward prediction processing. B pictures are encoded referring to the nearest past and future I and P pictures by bi-directional prediction. After the referenced I or P pictures are decoded, the B-picture can be decoded. The B-picture has the highest compression rate. A picture is composed of multiple blocks, and a block is the basic unit for encoding and decoding a picture.

[0023]FIG. 1 shows the block diagram of a conventional DVD player 100. The DVD player 100 is used to decode the incoming bit-stream S into audio A and video V outputs. The Bit-stream Parsing System 110 receives the MPEG bit-stream S and parses the MPEG bit-strea...

Abstract

A method and an apparatus of picture display. The invention displays the first picture and the second picture and displaying at least one virtual picture in between the first and the second picture. The motion compensator is included in a DVD player. The method includes: decoding the first and the second pictures from the received bit-stream; creating the virtual picture parameter according to the transition effect; and generating the virtual picture according to the virtual picture parameter by the motion compensator.
