摘要： A picture decoding section starts to decode a bit-stream for one picture when a decoding start command is supplied from a decoding start command generating section, and outputs a decoding completion command when the decoding is completed. Decoded picture data is stored in a decoding frame buffer. The decoding frame buffer outputs a bufferfull notification when a certain quantity of picture data is stored. The decoding start command generating section outputs the decoding start command to the picture decoding section when a decoding completion command is outputted from the picture decoding section and the bufferfull notification is not outputted from the decoding frame buffer.

摘要： In storing decoded image data of a picture into a memory 23, PTS1 and a valid/invalid flag F1 corresponding to the picture are stored at the top boundary address ADR1 of a storage area within the memory 23, ADR1 is temporarily held in a register circuit 211. whether a read address ADR coincides with any one of addresses ADR1 to ADR3 within the register circuit 211 is detected while sequentially reading data from the memory 23 to display a picture. When coincidence is detected, the data read from the memory 23 are retrieved as PTS and F, and control corresponding to a time difference between STC and retrieved PTS is executed if F indicates validity. When coincidence is not detected, the data read from the memory 23 are used as display decoded image data DAT4.

摘要： A detecting circuit detects a boundary in a bit stream which is coded in compliance with a predetermined rule. The boundary is a point at which discontinuity of reproduction time occurs. An inverting circuit inverts a specific bit in a header of a succeeding bit stream immediately subsequent to the boundary, in response to the detection of the boundary by the detecting circuit. The boundary can thus be detected easily by simply monitoring the specific bit, for example, in outputting the decoded bit streams. This consequently facilitates synchronous management and the like of the bit streams. The specific bit is included in the bit stream. Thus, detecting the specific bit allows simple and accurate detection of the boundary at which discontinuity of the reproduction time occurs.

摘要： This invention relates to an internal combustion engine including an oil seal ring between a cylinder block and a crank shaft, a crank shaft cap and a conduit. The cylinder block includes a plurality of cylinders, a crank shaft support portion and an oil seal retainer. The crank shaft support portion is located under the plurality of cylinders and the oil seal retainer projects outwardly from the cylinder block. A crank case is defined within the cylinder block. The crank shaft cap is secured to the crank shaft support portion and an opening is defined therebetween. The crank shaft includes a main journal and a flange portion. The main journal is inserted into the opening defined between the crank shaft support portion and the crank shaft cap. The crank shaft is rotatably mounted on both the cylinder block and the crank shaft cap. The flange portion extends outwardly from the main journal and is spaced from the crank shaft support portion and the oil seal retainer of the cylinder block, so that a cavity is defined between the flange portion of the crank shaft, the oil seal retainer, the crank shaft support portion of the cylinder block and the crank shaft cap. The oil seal ring is located between the oil seal retainer of the cylinder block and the outer peripheral surface of the flange portion. The conduit is defined within the crank shaft support portion or the crank shaft cap. The conduit communicates the cavity with the crank case.

摘要： A method and device for decoding received coded image data for image compression in moving picture telecommunication, wherein data are subjected to discrete cosine transformed coded compression to enhance decoding processing performance. To reproduce high precision moving pictures, positional information within an image block is scanned by a run/level dividing device from run values of the received data composed of the combination of run values and level values. Each pair of run and level values are subjected to a reverse quantifying process to form pairs of position and level values wherein the positional information and the level values correspond to each other. The level values are transformed into positional information using the zigzag scan and are also reverse quantified. A reverse discrete cosine transforming device carries out processing of the reverse quantified data to decode the image data.

摘要： A video decoding device which enables smooth reverse playback of 3:2 pulldown video streams. A video data storage unit stores pictures constituting a video stream that is being played back, where each picture consists of a first field and a second field. An attribute data storage unit stores attribute data which describes how each picture should be displayed. The attribute data includes a repeat-first-field flag for each picture. When playing back the video stream in a reverse direction, a reverse playback unit determines whether the repeat-first-field flag is set or cleared, and reads out the first and second fields of each picture in the same order as that in forward playback mode if the repeat-first-field flag is set. If the repeat-first-field flag is cleared, it reads out the first and second fields in the opposite order to that in the forward playback mode.

摘要： A decoded picture and parameters of a sequence layer, a GOP layer and a picture layer respectively for displaying the decoded picture are stored as a set in each of picture banks and parameter banks of a frame memory. Parameters of each layer stored as a set with a picture decoded immediately before are read out. Parameters attached to a picture to be decoded are decoded overwritten. Thus, the parameters of each layer stored as a set with the picture to be decoded are generated.
