Abstract: In an embodiment, a PATS counter synchronized with an SCR superposed on an MPEG-TS is used. When recording the MPEG-TS, a pair of the value of time stamp information (PTS/DTS) of a previously detected picture and the value of the PATS counter are stored (ST500-ST510). When detecting the next time stamp information, an increase in the time stamp information is compared with an increase in the PATS counter (ST512-ST526). If the significant difference is exhibited (YES in ST600), it is determined that an error is found in the time stamp information value, and a recording process is performed (ST530).

Abstract: According to one embodiment, a metadata processing apparatus which communicates with a server that holds metadata, the metadata processing apparatus includes a metadata update module configured to update metadata pertaining to content, a transmission module configured to transmit, to the server, content identification data for identifying the content to which the metadata updated by the metadata update module pertains, a reception module configured to receive data transmitted from the server, a determination module configured to determine, on the basis of the data received from the server by the reception module, whether it is necessary to upload the metadata updated by the metadata update module, and a notification module configured to invoke notification that presses upload of the metadata updated by the metadata update module to the server when the determination module has determined that upload is necessary.

Abstract: The copy-related information of an input video signal is detected and the copy control information of RDI located at the head of each video object unit and the scrambling control information described in the packet header of the video packets in the video object unit to which the RDI belongs are rewritten so as to coordinate the contents of the copy-related information, those of the copy control information and those of the scrambling control information.

Abstract: The aspect ratio information of an input video signal is detected and rewritten in such a way that the contents of the aspect ratio information of RDI located at the head of each video object unit and the contents of the aspect ratio information in the sequence header of the compressed video data in the VOBU to which the RDI belongs are coordinated.

Abstract: An image reproducing apparatus reproducing image information, having a reproduction processor reproducing the image information stored in the recording medium, a key input section having a skip key, a first skip processor, when the skip key is pressed one time, skipping the reproduction of the image information by the reproduction processor for a first predetermined period and resuming the reproduction of the image information by the reproduction processor after the first predetermined period is passed, and a second skip processor, when the skip key is pressed twice in a certain period, skipping the reproduction for a second predetermined period having the first predetermined period and a third predetermined period which is longer than the first predetermined period and resuming the reproduction of the image information by the reproduction processor after the second predetermined period is passed.

Abstract: A video recording and reproducing apparatus according to the present invention is characterized by a hard disk device and a DVD-RAM drive which records a video signal and management information for the video signal in a recording medium and an MPU which senses that a vertical blanking interval of an inputted video signal contains a WSS signal that may be outputted to an effective video area and in that if the MPU detects the containment of the WSS signal, the MPU records intrinsic information indicative of the containment of the WSS signal in a management information recording area of the recording medium.

Abstract: A video on demand system includes one or more hybrid fiber coax access networks connecting set top units to corresponding head end units. The head end unit for an access network is connected to an asynchronous transfer mode wide area network (ATM WAN). A hierarchical system of video servers, including at least one center server and at least one local server, or cache node, are also connected to the ATM WAN. When a user wishes to select a video, a service control unit coupled to the ATM WAN generates a selection list of proposed videos for which server and network resources are available to immediately serve the user-selected video. The service control unit determines whether server and network resources are available by sending separate queries to server and network resources management control units. Alternatively, the service control unit may generate the selection list based on whether the probability of a particular video being immediately served is greater than a threshold.

Abstract: An information transmit system includes a first communication element having a guaranteed quality required to transmit real-time information, and a second communication element different from the first communication element. The system also includes a transmission element for transmitting stored real-time information using the first communication element and for transmitting real-time data using the second communication element, where the real-time data using the second communication element has corresponding time stamps later in time than the real-time data transmitted by the first communication element. For example, a time stamp of the real-time data may be used to transmit the data in either a normal direction (using the first communication element), or in a retrospective direction (using the second communication element).

Abstract: A video coding apparatus ensuring a high coding efficiency even at a low bit rate includes a moving object analyzer which extracts a moving part from an input picture signal, analyzes its motion, and outputs a residual signal relative to a reconstruction image and motion parameters. The apparatus further includes a residual coding device for coding the residual signal, a reconstruction device for reconstructing a picture using the motion parameters, and a device that performs a variable length coding of the motion parameters and residual coded information.
