A method for creating seamless presentation information of picture data in a recording medium, the method comprising: recording picture data on the recording medium by grouping the picture data into objects; determining whether a current object of the picture data is to be presented seamlessly or non-seamlessly with a previous object of the picture data; creating an indication information indicating whether or not the current object of the picture data is to be presented seamlessly with the previous object based on a result of the determination; and selectively recording the seamless presentation information for a corresponding object only when the current object is to be presented seamlessly, wherein the seamless presentation information only includes a first system clock reference for the corresponding object and at least a last system clock reference field of a previous object when the current object is to be presented seamlessly with the previous object and does not include the first system clock reference for the corresponding object and the at least the last system clock reference field of the previous object when the current object is not to be presented seamlessly with the previous object.
