  • Publication number: 20120308207
    Abstract: For a large capacity recording medium, a user interface having high flexibility and enriched representation is accomplished. A flag that represents whether a play item has a multiple angle structure of which the play item is reproduced with a plurality of angles is described. In addition, a flag that represents whether the beginning of each decode unit is an angle switchable point is described. In a seamless multiple angle structure, the current angle can be switched without need to increase the number of interleave units. In a nonseamless multiple angle structure, with the flag, in a predetermined region on the rear end side of each angle, the current angle is prohibited from being switched. Thus, when a play item exits from the multiple angle, discontinuity in the reproduction can be prevented. In addition, with a flag that represents whether a sub play item should be reproduced not in synchronization with a main path, the sub play item of only audio data can be used as a BGM.

  • Patent number: 8285110
    Abstract: There is provided an apparatus and a method for generating record data, guaranteeing seamless playback even in a case of occurrence of a jump. In a multilayer disc having a plurality of recording layers, it is configured that an allowable range of an intra-layer jump and an inter-layer jump carried out in a playback processing of an information recording medium is determined and a required time for the intra-layer jump and the inter-layer jump is calculated on the basis of the determined allowable jump range information so as to determine a data configuration requirement such as an allowable minimum consecutive data size of data to be stored in the information recording medium on the basis of the calculated required jump time. With the present structure, seamless playback is made possible even in a case of occurrence of not only an intra-layer jump but also an inter-layer jump.

  • Patent number: 8279941
    Abstract: A picture decoding method and apparatus for decoding a bit stream, the bit stream being compatible with MPEG 1 moving picture video standard. The method includes receiving, via an input terminal, from the bit stream that includes extension data added in a header of a picture layer of the bit stream when the header includes control data newly added in MPEG 2 standard format, a picture coding type and the extension data of an anterior header of the picture layer. The bit stream in the picture layer is decoded using the picture coding type and the extension data of an anterior header of the picture layer when an extension start code indicating the beginning of the extension data of the current header is not received from the bit stream.

  • Patent number: 8279939
    Abstract: Control data subsequent to an extension start code is stored in an encoding apparatus when transmitted after each header data of a video sequence layer, a GOP layer, a picture layer and a slice layer. And in transmission of the next header data, the content of the control data subsequent to the extension start code in the header data to be transmitted is compared with the content of the preceding header data of the same layer stored in the encoding apparatus. And if the result of such comparison signifies that the compared data are mutually the same, neither the extension start code nor the subsequent control data is transmitted. At the reception of each header data of the video sequence layer, the GOP layer, the picture layer and the slice layer, the control data decoded subsequently to the extension start code is stored in the decoding apparatus.

  • Patent number: 8281156
    Abstract: A data placement configuration which ensures seamless playback of contents having segment portions including multiple different variations of encrypted data is provided. With regard to contents having segment portions configured of multiple different variations of encrypted data to which individual segment keys have been applied, and non-segment portions serving as encrypted data to which a unit key has been applied, the placement of segment data and non-segment portion configuration data is determined such that the maximum jump distance executed at the time of playback processing is equal to or less than a maximum jump distance set beforehand. Data placement has been determined based on seek time, ECC block processing time, sequence key usage time which is key switchover time, and so forth.
