摘要： A playback device executes playback of video data in sync with an application program associated with the video data. The playback device includes an activating unit for activating the application program, a receiving unit for receiving from a user an input specifying a playback section associated with a piece of video data and an application program, and an activation control unit. If a first input is received from the user by the receiving unit and a second input is received within the predetermined time period from reception of the first input, the activation control unit discards the first input. If a third input is not received within the predetermined time period from reception of the second input, the activation control unit activates an application program according to the second input.

摘要： A playback device that creates a virtual package by combining a structural element recorded on a BD-ROM with an additional content recorded on a removable medium. The middleware in the playback device is provided with a file I/O module 34 that controls data input/output of the removable medium, in accordance with a request from an application program. When a BD-J application requests writing the structural element of the virtual package and the additional content to be written is an AV stream, the file I/O module 34 writes the structural element into one or more allocation units composed of a plurality of continuous empty logical blocks in the removable medium. When the additional content to be written is not an AV stream, it writes the additional content into a normal data area that is composed of a plurality of separately scattered empty blocks in the removable medium.

摘要： A BD-ROM stores PlayList information. The PlayList information defines a playback section of each of a plurality of AV clips and includes MainPath information and SubPath information. The MainPath information designates one of the AV clips as a Main Clip and defines a portion of the Main Clip as a primary playback section. The SubPath information designates another one of the AV clips as a SubClip and defines a portion of the SubClip as a secondary playback section that is to be played back in synchronism with the primary playback section. The BD-ROM stores, the one of the AV clips designated as the SubClip along with an EP_map. The EP_map shows a plurality of entry points on the SubClip in a one-to-one correspondence with entry times on the SubClip timeline.

摘要： In a playback device for playing back a moving image recorded on a recording medium while executing an application recorded on the recording medium, to improve the use efficiency of a memory bus when combining the moving image with an image relating to the application. Whether or not to combine a background image, which is used as a background of GUI graphics such as a menu or a moving picture used by the application, is determined depending on whether the moving image covers the entire background image. If the moving image covers the background image, there is no need to combine the background image with the moving image. In this case, a memory bus allocated to the reading of the background image can be used for, for example, writing the moving image read from the recording medium onto a memory. Hence the memory bus bandwidth can be effectively used.
摘要翻译：在用于在执行记录在记录介质上的应用程序的同时再现记录在记录介质上的运动图像的回放装置中，当将运动图像与与应用有关的图像组合时，提高存储器总线的使用效率。根据运动图像是否覆盖整个背景图像来确定是否组合用作GUI图形的背景的背景图像，诸如由应用使用的菜单或运动图像。如果运动图像覆盖背景图像，则不需要将背景图像与运动图像组合。在这种情况下，分配给背景图像的读取的存储器总线可以用于例如将从记录介质读取的运动图像写入存储器。因此，可以有效地使用存储器总线带宽。

摘要： A playback apparatus has a platform 1410 that is a program execution environment of an application 1400. When the platform 1410 initiates the application 1400, a graphics information transmission unit 1403, which corresponds to an API function, obtains graphics information and stores the graphics information in a graphics information storage unit 1413. A graphics information control unit 1414 selects graphics information to be rendered, based on a stream event obtained by a stream event reception unit 1416 and the graphics information stored in the graphics information storage unit 1413. The graphics information control unit 1414 has a graphics rendition unit 1415 render the selected graphics with a video playback timing relating to the stream event.

摘要： The present invention relate to a digital broadcast system, and it is an object of the invention to record contents quickly in a broadcast system which implements interactivity by transmitting a set of data repeatedly, wherein a digital broadcast receiver separates a table corresponding to video images from streams in an arbitrary order and repeats the processing of memorizing the video image data to be identified in the order of obtaining the same by means of the table corresponding to the video images until all of the set of video images have been memorized. This allows for performing, in a short time, storage process of video image data broadcast for the purpose of efficient reproduction by a receiver having no storage function. Additionally, the data is available to viewers at any time after the completion of storage thereof.

摘要： A BD-ROM on which an AVClip and a Java™ application are recorded. The AVClip includes a video stream and an audio stream multiplexed therein. On the BD-ROM recorded further are management information and the Mixing_On flag corresponding to the management information. The management information indicates a playback control of the AVClip that is to be played back when the Java™ application is executed. The Mixing_On flag indicates whether or not when a user performs an operation on the Java™ application being executed while the AVClip is under the playback control, mixing of the click sound with an audio output of the AVClip is available.
