摘要： In DVD Stream Recording Stream Object Units are real-time recorded, wherein such fixed-length Stream Object Units serve as a container for Application Packets that have a variable length and carry payload data and an Application Time Stamp, this timestamp enabling proper real-time playback. In case the temporal distance between two succeeding application packets is too big, stuffing data must be inserted into the corresponding Stream Object Units. The real-time stuffing control is performed such that overflow of the input buffer is avoided in case of a specific kind of input signals.

摘要： MPEG2 data streams contain data packets for a set of programs and time stamps for data synchronization purposes. An MPEG2 transport stream is assembled of fixed-length transport packets. The received transport packets of at least one specific program of this set of programs can be stored using for example a DVD Streamer recorder or DVD-RAM recorder. For the real-time playback of recorded specific program data packets each packet needs a separate time stamp. For that reason a timestamp is to be captured for each data packet at recording time. However, capturing of timestamps from a transport stream is a very time consuming action in software implementation processing. Therefore transport stream timestamps are captured for every Nth packet only and the missing timestamps are calculated. Thereby software-processing time is saved for generating the timestamps required for real-time bitstream recording.

摘要： A set top box can be connected to a DVD Streamer via an IEEE1394 interface which contains means to timestamp data and to strip off these timestamps again, using them for timing regeneration. The DVD stream also must regenerate the timing of data packets as it was upon recording, when these packets are played back. The streamer could also use its own timestamps and strip them off again when replaying. So, in total, there is an in-series connection between two time stamping and time regeneration mechanism which introduces jitter accumulation.

摘要： A DVD transport stream including a video and a sub-picture stream shall be transcoded to a broadcasting transport stream. For this a decoding-encoding-chain merging video and sub-picture into a single video bitstream to conserve the information of the sub-pictures although not in the broadcasting format reserved is provided. By performing a sub-picture macroblock analysis the transcoding can be controlled such that the motion estimation unit of a standard MPEG-2 encoder and/or the entire decoding loop within the encoder can be saved.

摘要： The invention relates to a method and an apparatus for determining a disparity value for an object located in or to be placed into a stereoscopic image pair having an associated disparity map. First an area to be analyzed in one of the stereoscopic images is determined Then a histogram is built from disparity estimates of the associated disparity map that fall within the determined area. Subsequently a contiguous range of bins is searched in the histogram that also contains a sufficient number of pixels. Finally, a disparity estimate for the determined area is selected from the contiguous range of histogram bins.

摘要： Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are “unselected”, “selected” or “activated”. According to the invention, the representation of a menu button may vary, depending on its state. An image or an image sequence, e.g. cartoon, may be associated to a buttons state, providing user animation. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. A data structure is disclosed which allows storage of such menu data e.g. on a Blu-ray disc.

摘要： The IEEE1394 bus communication protocol has three layers: physical layer, link layer, and transaction layer. A link layer IC implements the interface to an external application and prepares data for sending on the bus, or interprets incoming data packets from the IEEE1394 bus. A physical layer IC implements the direct electrical connection to the bus and controls many functions including arbitration for sending data on the bus. A problem exists due to the fact that the header data of the IEEE1394 asynchronous data packets consists of 32 bit words which have to be interpreted as 32 bit words in the connected application data processing unit (30). The IEEE1394 bus interface unit (20) is defined to be of big endian type. In a little endian type application data processor (30) the data word order can only be correctly interpreted after a byte order change. According to the invention the byte order change is performed in the data link layer unit (21) automatically with hardware circuitry for asynchronous data packets.

摘要： A method for regenerating the original data of a digitally coded video film is described, in which a specific picture type of a number of picture types (I, B, P) has been allocated to each of the individual pictures during coding and the coding order (DEO) does not correspond, at least in part, to the display order (DIO). This method provides for an independent time base to be used in order to recover the display order, which time base is obtained from internal information items in the decoder, the information items having been stored during the preceding decoding of a number of pictures. This method has the advantage that even with the omission of a header of a Group of Pictures (GOPH), the correct display order can still be achieved, even if the otherwise customary temporal reference codes in the bit stream signal an incorrect display order.

摘要： There are provided methods and apparatus for synchronized stream packing of packets that differ contextually between A/V streams in a parallel presentation. A method includes the step of identifying sub-picture/subtitle packets and/or audio packets having arrival timestamps and/or presentation timestamps that match an arrival timestamp and/or a presentation timestamp, respectively, of video packets. The method also includes the step of packing a Video Object Unit (VOBU) and/or a Transport Stream (TS) with the identified sub-picture/subtitle and audio packets and the video packets having the matching timestamps.
