    • The present invention relates to a technology for satisfactorily realizing trick play in a video-on-demand system that transmits video contents to video receivers. For example, even when the interval between key frames which is coded in intra-frame coding is unequal and the data size of a key frame is not uniform, trick play can be achieved using the key frames within a permissible transmission bit rate. Herein, the transmission start time instant and transmission completion time instant of each key frame that should be transmitted are calculated. If the transmission completion time instant of a preceding key frame and the transmission start time instant of a succeeding key frame are incompatible with each other, the transmission of the succeeding key frame is canceled. If the above time instants are compatible, the succeeding key frame is transmitted at the transmission start time instant.
    • 本发明涉及一种在视频点播系统中令人满意地实现向视频接收机发送视频内容的技术。 例如,即使在帧内编码中编码的关键帧之间的间隔不相等且关键帧的数据大小不均匀的情况下,也可以利用允许的传输比特率内的关键帧来实现特技播放。 这里,计算应该发送的每个关键帧的发送开始时刻和发送完成时刻。 如果先前关键帧的发送完成时刻和后续关键帧的发送开始时刻彼此不兼容,则取消后续关键帧的发送。 如果上述时刻兼容,则在发送开始时刻发送后续的关键帧。
