Abstract

Távközlési rendszerben video képkockák kódolására vonatkozó eljárássorán egymást követő álló képkockákból álló video képkocka füzértalakítanak ki. Egy változat szerint legalább egy képkocka képkocka-helyreállítási adatait referencia képkockaként, valamint korábbankódolt szomszédos blokkok mozgásadatait eltárolják, egy vagy többkorábban kódolt, az eltárolt referencia képkocka alapján kialakítottszomszédos blokk mozgásadatai alapján a kódolandó blokk mozgásadataités a kódolandó képkocka képkocka-helyreállítási adatait meghatározzák.Egy másik változat szerint legalább egy, referencia képkockánaktekintett képkocka képkocka-helyreállítási adatait, és korábban kódoltszomszédos blokkok mozgási adatait eltárolják, és az éppen kódoltképkocka képkockablokkjának mozgási adatait az éppen kódolt képkockaképkockahely-reállítási adatainak kódolása során használt referenciaképkockával azonos referencia képkockával rendelkező szomszédosblokkok kizárólagos felhasználásával meghatározzák. Ezt követőenmindkét változat esetében a kódolandó blokkot képviselő, előremeghatározott képminőség mellett előre meghatározott kódolásihatékonyságot eredményező képkocka helyreállítási adatokat és mozgásiadatokat felhasználásra kiválasztják. A találmány tárgya még azeljárást megvalósító előfizetői terminál, videó kóder és számítógéppelolvasható programtermék. ÓIn a telecommunications system, a sequence of video frames consisting of consecutive still frames is formed according to the procedure for coding video frames. According to one version, the frame recovery data of at least one frame is stored as a reference frame, as well as the motion data of previously coded adjacent blocks, based on the motion data of one or more previously coded adjacent blocks formed on the basis of the stored reference frame, the motion data of the block to be encoded determines the frame recovery data of the frame to be encoded. Another version the frame recovery data of at least one frame considered as a reference frame and the motion data of previously encoded neighboring blocks are stored, and the motion data of the frame block of the currently encoded frame is determined by the exclusive use of adjacent blocks with the same reference frame as the reference frame used during the encoding of the frame location restoration data of the currently encoded frame. After that, in the case of both versions, frame recovery data and motion data representing the block to be coded and resulting in a predetermined coding efficiency in addition to a predetermined image quality are selected for use. The subject of the invention is also a subscriber terminal implementing the method, a video encoder and a computer-readable program product. HE
