摘要： PROBLEM TO BE SOLVED: To provide a motion picture decoding and playback method for preventing a distorted image from being played back when an error is mixed into a first frame of a motion picture, and to provide a motion picture decoding and playback apparatus.
SOLUTION: When reception of a frame is started (steps 21a, 21b) and an inter-frame coded frame is received ("unknown frame interval in step 21c") or when a frame including an error is received ("present" in step 21s), the received frame is not decoded/played back. When an intra-frame coded frame including no error is received ("absent" in step 21d), frames received subsequently are decoded and stored in a buffer (steps 21e, 21h), and frames stored in the buffer are played back, thereby preventing a distorted image from being played back.

摘要： PROBLEM TO BE SOLVED: To detect a moving object based on data digitally coded and picked up by a camera. SOLUTION: An image signal from a monitor television camera 11 is converted into digital image compression coded data by a coding section 12. The coding section 12 encodes picture element information being a difference of an image between a preceding pattern and this pattern or between a succeeding pattern and this pattern and information of a motion vector representing the magnitude and the direction of the motion between the two patterns in the unit of plural blocks. The coded data are decoded by a decoding section 14 of a monitor center or the like. A motion vector as to a moving object in the case of decoding is extracted by a mobile object detection discrimination section 16. The discrimination section 16 extracts the motion vector and extracts an object block based on a motion index to obtain a static quantity and to discriminate the object moving object through the comparison with a reference value.

摘要： PROBLEM TO BE SOLVED: To enable trick reproduction of motion image content including video data coded by the H.264 coding method.
SOLUTION: When performing frame skipping reproduction, IDR access units are extracted from coded video data including a plurality of access units, and it is determined whether there is an access unit delimiter NAL, which is boundary information indicating a boundary between the IDR access units, at the head of the extracted IDR access units. When there is no access unit delimiter NAL, information relating to the access unit delimiter NAL is inserted at the head of the IDR access units. The boundary between the access units is identified by detecting the access unit delimiter NAL, and coded video data consisting of the IDR access units is decoded.

摘要： PROBLEM TO BE SOLVED: To improve reproducibility of an edge pattern even when detection precision of the edge pattern from an adjacent area is low. SOLUTION: A concealment unit 300 detects the direction of a dominant passing a missing pixel position P(i, j) based upon a gradient vector and selects a pair of boundary pixels Pa1 and Pa2 disposed on the straight line of the edge. Further, pairs of boundary pixels Pb1 and Pb2, and Pc1 and Pc2 present within a range of an angle or pixel positions specified with a threshold are selected from a plurality of pairs of boundary pixels disposed in a circumference of the pair of boundary pixels Pa1 and Pa2. Difference values among the selected pairs of boundary pixels Pa1 and Pa2, Pb1 and Pb2, and Pc1 and Pc2 are calculated respectively to select a pair of boundary pixels having a minimum difference value, and a pixel value for interpolating the missing pixel P(i, j) is calculated based upon the pixel values of the selected pair of boundary pixels and distances d1 and d2 to the missing pixel P(i, j).

摘要： PROBLEM TO BE SOLVED: To allow a receiver side to quickly reproduce correct video image information after on the occurrence of an error or missing in video information resulting from revision of a radio channel. SOLUTION: A PHS base station 9 gives a previous notice to a device that encodes video information transmitted through a radio channel when the radio channel formed between a PHS multimedia communication terminal 5 and a PHS terminal 7 requires a revision and gives an end notice to the device that encodes video information transmitted through the radio channel when the revision of the radio channel is completed. The device receiving the notice can reproduce the video regardless of the video information affected of the channel revision by transmitting in-frame coded video information after the end of the channel revision.

摘要： PROBLEM TO BE SOLVED: To provide a moving picture encoder capable of enhancing view quality of a moving picture so as to smoothly reproduce a stable moving picture. SOLUTION: An encoding mode setting section 6 estimates a generated code amount when one picture is intra-coded and also estimates a buffer occupied amount of a virtual buffer when the generated code amount is removed. The encoding mode setting section 6 estimates a frame rate on the basis of the estimated buffer occupancy amount. A device control section 7 designates a desired frame rate. The moving picture encoder decides whether or not a difference between the estimated frame rate and the designated frame rate is a prescribed or more and executes the intra-coding when the decided difference of the frame rate is less than the prescribed value or executes the inter-coding when the decided difference of the frame rate is the prescribed value or more, as its control.
