Abstract: A UMID extracting/embedding unit 10 extracts UMID data embedded in material data. A CPU 11 updates a generation indicated by generation data in the extracted UMID data to generate new generation data when processing accompanied by a deterioration of quality is applied to the material data such as recording to a database 8. The UMID extracting/embedding unit 10 embeds the new generation data in the material data.

Abstract: A clip without UMID is transmitted to a disc drive from an editing device. The disc drive generates the UMID and NRT with respect to the transmitted clip, and stores the UMID in association with the NRT. The editing device edits the NRT, and transmits the NRT that is edition results to the disc drive. The disc drive overwrites the NRT that has been transmitted from the editing device on the generated NRT, and stores the NRT in association with the clip with the UMID. The present invention can be applied to a disc recording and reproducing device.

Abstract: The present invention relates to a playback apparatus, a playback method, and a program for the same that increase the level of convenience of a recording medium and thereby, for example, enable a user to perform playback control processing and the like more easily. An information acquisition unit 353 in a playback control unit 334 allows a holding unit 354 to hold an acquired an Linear Time Code (LTC) change point table 361. An input acceptance processing unit 352 supplies an accepted cue-up instruction to a cue-up processing unit 355. The cue-up processing unit 355 identifies the File Time Code (FTC) of a frame to be cued up, referring to the LTC change point table 361 held in the holding unit 354, and supplies this information to a control unit 351. Based on the information, the control unit 351 creates cue-up command information and supplies it through a command processing unit 356 to a disk recording/playback apparatus which displays a frame image of a frame to be cued up onto a monitor.

Abstract: The present invention relates to an information processing apparatus and method, a program, and a recording medium that facilitate, for example, identification of information recorded on an recording medium. In a disc formatting process 211, a disc-metadata-file creating unit 181 creates a disc-metadata file including various types of label information, using a PROAV-ID copying unit 192 and a representative-image setting unit 194. Furthermore, in a disc-metadata updating process 212, a disc-metadata-file managing unit 182 updates the disc-metadata file, for example, using the representative-image setting unit 194. A disc-metadata-file recording controller 183 executes a process of comparing PROAV IDs using a PROAV-ID comparing unit 193, and records the disc-metadata file on a disc 132 when the PROAV IDs match. The present invention can be applied to an editing apparatus.
