A method and apparatus for generating a multimedia document that includes video image samples and associated audio is accomplished by decoding video signals into decoded video representations, sampling the decoded video representations at a rate below the motion video frame rate, and storing the video samples as a video document. For example, a JPEG (Joint picture expert group) document. In addition to creating video documents, the present method and apparatus also digitizes received audio signals and stores the digitized audio as an audio document. For example, as an AIFF (audio interchange file format audio format which is used with MAC OS(TM)) audio document, a WAV (which is used with Windows(TM)) audio document, or a RealAudio(TM) (which is the Internet standard for delivering continuous audio) audio document. Once the video document(s) and audio document(s) are created, they are mapped together and stored as a multimedia document, which may be a hypertext document, such as an HTML (hypertext markup language) document.
