摘要： Each of a first data stream in a first format and a second data stream in a second format is an arrangement of a plurality of data units, each including compressed and encoded video data. In the first and second formats, first and second time ranges are respectively set to define a permissible variation in the video playback duration of the respective data units. The method includes the steps of: receiving a content representing the video; generating the compressed and encoded video data of the content; making the data units out of the video data such that the playback duration of each said data unit falls within both of the first and second time ranges; and recording the first data stream, including the data units, on the storage medium.

摘要： A data processing apparatus can write a video stream related to video on a recording medium. The data processing apparatus includes: a signal acquisition section for acquiring a video signal related to the video; a type identification section for identifying a type of the video based on the video signal, the type of the video being determined in accordance with picture counts of the video displayed per unit time; a stream generator for generating a video stream based on the video signal; a controller for determining, based on the type of the video, whether to disable the writing of the video stream or to enable the writing of the video stream with lowered video quality; and a writing section for controlling, based on the decision of the controller, the writing of the video stream to the recording medium.
