摘要： PROBLEM TO BE SOLVED: To discriminate which frame images are reproduced after returned from an error even if the error occurs during the reproduction of coded moving picture data which do not include time stamp information, and to perform the display of correct time information. SOLUTION: When the device detects the error during reproduction of the coded moving picture data, a coded picture in a screen succeeding to a frame including data which have become errors based on management information showing a recording position of the coded picture in the screen included in the coded moving picture data is searched, the position to return from the error is determined, and, displayed elapsed time information is updated based on a searched frame number of the coded picture in the screen when returned from the error.

摘要： Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.

摘要： PROBLEM TO BE SOLVED: To provide a transmission apparatus capable of improving subjective picture quality by reducing flickering of a displayed image on a reception side which accompanies the change in image transfer rate. SOLUTION: A communication capacity is possible to become insufficient if a high image transfer rate is kept when a radio transfer rate is lowered to follow degradation in radio communication quality, resulting in image error. In that case, a transmission control part 163 of a radio transmission part 16 lowers the image transfer rate without delay. When the radio communication quality improves, it raises the image transfer rate when a period in which the radio transfer rate is higher than the image transfer rate continues for a certain period.
