影像记录再现装置
摘要：
本发明提供一种影像记录再现装置，即使记录与再现不同步，也能够在不设置同步变换电路(帧同步器等)的条件下执行记录再现动作。由输入处理部(141)将包括影像素材的SDI信号编码，编码的影像数据由输入缓冲器(142)暂时保持。保持的编码的影像数据从输入缓冲器(142)读出，输出并蓄积至蓄积处理部(15)。另外，读出蓄积处理部(15)中保存的其他的编码的影像数据，暂时保持在输出缓冲器(161)中。此时，对应于与输入同步信号不同步、而由同步信号生成部(12)输出的与外部黑场信号同步的或内部产生的同步信号的周期，来进行编码的影像数据从输入缓冲器(142)的读出，另外，读出的编码的影像数据被转发至蓄积处理部(15)。
摘要（英）：

A video recording and playback apparatus can perform the recording operation and the playback operation without a synchronous conversion circuit (frame synchronizer and the like) is provided, even ifrecording and playback are asynchronous. An SDI signal containing video content is coded by input processing unit 141, and the coded video data is temporarily held by input buffer 142. The coded videodata is read from input buffer 142, is outputted and is stored in storage processing unit 15. Other coded video data stored in storage processing unit 15 is read and is held temporarily in output buffer 161. Reading-out of the coded video data from input buffer 142 does not synchronize with an input synchronizing signal and is performed according to the cycle of the synchronizing signal generatedby external synchronizing signal detector unit 12, and the coded video data read out is transmitted to storage processing unit 15.
