Title:
【発明の名称】画像シーケンスのビデオデータの符号化および復号化方法
Document Type and Number:
Japanese Patent JPH05503828
Kind Code:
A
Abstract:
The video data of a frame sequence are coded and decoded by batches, whereas each nth main frame data field (F1, F4) (= key frame) is transmitted as completely as possible. From two adjacent main frame data fields (F1, F4), n-1 phantom image data fields (P1, P2) are calculated at the emitter and receiver sides by means of n-1 motion fields (M1, M2). In addition, n-1 differential frame data fields (D1, D2) are determined on the emitter side, then transmitted with the main frame data fields (F1, F4). On the receiver side, the original sequence of the data fields (F1, F2, F3, F4,...) is again reconstructed from the transmitted data fields (F1, D1, D2, F4, ...) is again reconstructed from the transmitted data fields (F1, D1, D2, F4, ...) by a renewed calculation of the motion fields (M1, M2).
