Information processing device, information processing method and program, and recording medium

An information processing method, comprising:

• an attribute information formulating step of formulating picture attribute information of a still picture of a set of one or more still pictures;
• a replay control information formulating step of formulating replay control information that specifies a replay progression of at least one picture of said set of still pictures based on said picture attribute information, the replay control information including a replay start time of the still picture;
• and
• a recording step of recording said set of still pictures, said picture attribute information associated with said set of still pictures, and said replay control information associated with said set of still pictures, wherein
• said replay control information formulating step further includes formulating audio replay specifying information that specifies an audio replay progression of an audio stream reproduced simultaneously with the still picture based on attribute information of said audio stream,
• said recording step further includes recording said audio stream and the audio replay specifying information corresponding thereto on said recording medium,
• said audio replay specifying information includes at least one of first subsidiary information indicating whether said audio stream is synchronized or non-synchronized to the replay of the still picture, and second subsidiary information indicating whether or not said audio replay progression is to be reproduced repeatedly,
• when said audio stream is synchronized to the replay of the still picture, the replay start time of each still picture is predetermined such that each still picture is reproduced at a preset time, and
• when said audio stream is non-synchronized to the replay of the still picture, the replay start time of each still picture is not predetermined, and each still picture is reproduced according to a predetermined replay sequence and based on a user command.

A non-transitory computer readable storage medium encoded with a computer readable program configured to cause an information processing apparatus to execute a method, the method comprising:

• an attribute information formulating step of formulating picture attribute information of a still picture of a set of one or more still pictures;
• a replay control information formulating step of formulating replay control information that specifies a replay progression of at least one picture of said set of still pictures based on said picture attribute information, the replay control information including a replay start time of the still picture;
• and
• a recording step of recording said set of still pictures, said picture attribute information associated with said set of still pictures, and said replay control information associated with said set of still pictures, wherein
• said replay control information formulating step further includes formulating audio replay specifying information that specifies an audio replay progression of an audio stream reproduced simultaneously with the still picture based on attribute information of said audio stream,
• said recording step further includes recording said audio stream and the audio replay specifying information corresponding thereto on said recording medium,
• said audio replay specifying information includes at least one of first subsidiary information indicating whether said audio stream is synchronized or non-synchronized to the replay of the still picture, and second subsidiary information indicating whether or not said audio replay progression is to be reproduced repeatedly,
• when said audio stream is synchronized to the replay of the still picture, the replay start time of each still picture is predetermined such that each still picture is reproduced at a preset time, and
• when said audio stream is non-synchronized to the replay of the still picture, the replay start time of each still picture is not predetermined, and each still picture is reproduced according to a predetermined replay sequence and based on a user command.
