Moving picture encoding device, moving picture recording device, and moving picture reproducing device

摘要

A moving picture encoding device which can embed information of a CM boundary in encoded data of a television broadcast signal, a moving picture recording device which records the encoded data, and a moving picture reproducing device which can perform moving picture reproduction in accordance with the embedded CM boundary information are provided. The moving picture encoding device 101 includes an encoder 3 for encoding a broadcast signal of a television broadcast containing a television program period and a CM period to output encoded data, an encoding controller 4 for controlling the encoder 3 to intra-code periodic pictures at constant time intervals and to inter-code other pictures between the periodic intra-coded pictures at constant time intervals, and a CM boundary detector 1 for detecting a program-CM boundary, which includes a boundary when a television program period changes to a CM period and a boundary when a CM period changes to a television program period to output the information of the program-CM boundary, wherein a boundary position picture positioned on the program-CM boundary is intra-coded.
