1. An image recording method for multiplexing moving image data and sound data associated to said moving image data, said image recording method comprising the steps of:
- encoding said moving image data, said sound data and attached information related to said moving image data and said sound data, wherein encoded attached information having a unique identifying code; and
splitting and multiplexing said encoded attached information, said encoded sound data and said encoded moving image data by predetermined data sizes respectively, wherein said encoded attached information has a data size equal to or larger than playback auxiliary information which is referred to in playing back said moving image, wherein said encoded attached information is recorded in an area where said playback auxiliary information is to be recorded.

Abstract
An MPEG compression circuit records attached information (referred to as FF_PCK) at the initial address of a VOBU in which NV_PCK is to be recorded. NV_PCK is playback auxiliary information and is referred to when playing back moving images in DVD-Video format. Attached information (FF_PCK) has a data size equal to or larger than NV_PCK. FF_PCK is replaced by NV_PCK when converting MPEG2 data into DVD-Video data. As a result, it is not necessary to demultiplex and remultiplex moving image data and sound data so that data can be converted efficiently.
