摘要： PROBLEM TO BE SOLVED: To simply and accurately grasp a storage data quantity of a buffer memory without incurring a large-sized circuit scale and a high cost of an image pickup device even when a clock for processing image coding is asynchronous with a clock used by equipment in a post-stage. SOLUTION: A timer 23 counts a read clock RCK outputted from a transmission section 4 to clock a read time length corresponding to a write period, a correction means 223 obtains a difference Δt between the read time length and a time length of the write period, corrects a data quantity of a coded image signal read from a buffer memory 3 depending on this difference Δt, and a stored data quantity calculation means 222 calculates the stored data quantity by using the corrected read data quantity. Then a produced quantity of coded image signals by a coding processing section 21 is controlled so that the stored data quantity of the buffer memory 3 is always kept within a prescribed range based on the calculation result of the stored data quantity.

摘要： PROBLEM TO BE SOLVED: To correct a motion of an entire input image by predicting a global motion vector denoting a motion of the entire input image and using the predicted value. SOLUTION: A statistic calculation/prediction section 124 of the moving image coder applies storage processing to global motion vectors of each scene detected by a global motion vector detection section 122 and checks statistic properties as to a change in a motion of the entire image to discriminate the property of the change such as linearity and periodicity based on the statistic property. Then the statistic calculation/prediction section 124 predicts a global motion vector as to received images which follow present image, based on the statistic property and correction and performs the correction processing by using the predicted value. The calculation with respect to all blocks to obtain a motion of the entire image is omitted by predicting the entire motion of the succeeding input image based on the statistic property in this way, and the motion of the entire image is corrected by a small arithmetic operation.

摘要： PROBLEM TO BE SOLVED: To provide a reproduction device capable of performing stable reproduction by modifying errors from both sides, even when an A/V decoder is to be operated, based on a system clock different from a TS separator. SOLUTION: A PTS monitoring section 308 stores a PTS, corresponding to ES data read by the A/V decoder 400 from an audio buffer 306 or a video buffer 307. An STC determination section 309 estimates the system time clock D-STC, used by the A/V decoder 400 from the PTS stored in the monitoring section 308. A clock control section 311 controls a clock generating section 600 based on an estimation value E D-STC , which has estimated the D-STC. Accordingly, the system time clock STC, used by the TS separator 300, or the like, is controlled. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a receiver and a receiving method for never resulting in degradation of reproducing quality in the process of reducing overhead of data to be transferred to a buffer used under the time-shift reproducing mode and of switching the time-shift reproducing mode to the regular reproducing mode. SOLUTION: An accumulation buffer 123 is provided in the preceding stage to accumulate TS packets to an external memory 124 connected via an external IF unit 204 at the time of time-shift reproducing mode. Moreover, a reproducing buffer 125 is also provided in the successive stage. If the data are no longer accumulated in the external memory 124 while the time-shift reproduction progresses, a time-shift data management unit 126 executes temporary time-shift with the accumulation buffer 123 for actualization of reading and writing at the speed higher than the external memory 124 and the reproducing buffer 125 via no external memory 124. Thereafter, the time-shift reproducing mode is shifted to the regular reproducing mode with a separation mode control unit 105. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To maintain the value of a system time clock to be used for decoding processing at a value close to a clock value on the transmission side even when random processing delay is generated between packets.
SOLUTION: When storing TS data received and demodulated by a digital broadcasting reception unit 5 in a TS buffer 212 by a TSIF 211, the time value of an STC counter 215 is imparted to each TS packet as the reception time value of the TS packet. Then, in a TS separation part 213, when reading the TS packet from the TS buffer 212 and performing TS separation processing, in the case that a PCR is detected from the TS packet, the PCR is replaced on the basis of the imparted reception time value, the replaced PCR' is supplied to an STC control part 214, and the system time value of the STC counter 215 is adjusted.
