摘要： A reproducing apparatus includes a playback data acquisition unit for acquiring playback data containing encoded stream data, a decoding unit for decoding the stream data, a mixing unit for mixing data to be mixed, different from the stream data, with the stream data decoded by the decoding unit, and a selecting unit for selecting between supplying the stream data to the decoding unit and outputting the stream data, and a control unit for controlling the selecting unit. The control unit acquires, from the playback data acquired by the playback data acquisition unit, determination information indicating whether the playback data contains the data to be mixed with the stream data, and controls the selecting unit to output the stream data if the determination information determines that the playback data contains no data to be mixed and if data processed by the playback data processing unit is output as encoded data.

摘要： A block key to encrypt block data is generated using an ATS (arrival time stamp) appended to each of TS (transport stream) packets included in a transport stream correspondingly to the arrival time of the TS packet. The ATS is a random data depending upon an arrival time, and so a block-unique key can be generated, which enhances the protection against data cryptanalysis. A block key is generated from a combination of an ATS with a key unique to a device, recording medium or the like such as a master key, disc-unique key, title-unique key or the like. Since an ATS is used to generate a block key, any area for storage of an encryption key for each block may not be provided in a recording medium.
摘要翻译：使用与TS分组的到达时间相对应的附加到包括在传输流中的每个TS（传输流）分组的ATS（到达时间戳）来生成加密块数据的块密钥。 ATS是根据到达时间的随机数据，因此可以生成块唯一密钥，这增强了对数据密码分析的保护。块密钥是从ATS与设备唯一的密钥，诸如主密钥，盘唯一密钥，标题 - 唯一密钥等的记录介质等的组合生成的。由于使用ATS来生成块密钥，因此可能不会在记录介质中提供用于存储每个块的加密密钥的任何区域。

摘要： In a video TS packet separator, a video TS packet VTSP is extracted from a TS (transport stream). In a PES packet analyzer through a TS packet generator, the video TS packet is decoded, re-encodes at a predetermined bit rate, TS-packetized and supplied to a switch input terminal. The switch input terminal is also supplied with non-video TS packets UVTSP from a TS packet buffer. A controller is provided to control the TS packet generator and switch based on timing information and PCR from a TS packet timing manager. Thus, codes in the TS can be converted.

摘要： With a reproduction-only disc having a large recording capacity, an interactive function having a higher degree of freedom than the related art can be easily accomplished. A virtual player model corresponding to a function of a player is created and described in Java. BDBasicPlayer 210 detects a user input and the status change of the player and generates an event. An object 211 that implements a listener interface registers an event listener corresponding to an event that the object 211 is caused to receive to BDBasicPlayer 210 before the event takes place. When the event becomes unnecessary, it is unregistered. BDBasicPlayer 210 transmits the event to the object 211 in which the event listener has been registered. The object 211 executes a method corresponding to the received event. The relationships between events and methods can be flexibly set. Thus, a complicated interactive function can be easily accomplished.
