the buffer zone data
Tradução de "the buffer zone data" em chinês
所述缓冲区数据
的缓冲区数据
将缓冲区数据
A data storage unit 320 is configured to store the buffer zone data to the storage area storage fragment.
数据存入单元320用于将所述缓冲区数据存入存储区域的存储片。
Therein, the buffer zone data R Frame interval can be random or cyclical, for example, each cycle's corresponding video length is 1-3 seconds.
其中，所述缓冲区数据R帧的间隔可随机或周期，例如每个周期对应的视频的时长为1-3秒。
The first frame of the data of the buffer zone data to be stored to the storage fragment is an R Frame.
所述缓冲区数据中要存入当前存储片的数据的第一帧为R帧。
The video corresponding to the buffer zone data lasts for 1-3 seconds. Taking 2 seconds as an example, if the video data acquired in each second is 25 frames, then a unit of buffer zone data is 50 frames, wherein, the first frame is an I Frame or an R Frame, and only an extremely small minority are I Frames.
所述缓冲区数据对应的视频的时长为1-3秒，以2秒为例，如果每秒采集的视频数据为25帧，那么一个单位的缓冲区数据也就是50帧，其中第一帧为I帧或R帧，并且其中只有极少数的是I帧。
and then store the data that is to be stored to the new storage fragment to the new current storage fragment from the buffer zone data; buffer the buffered I Frame when the I Frame appears, and replace the buffered I Frame with a new I Frame when the new I Frame appears
并在所述新开辟的存储片的最前方插入所述缓存的I帧，再将所述缓冲区数据中要存入当前存储片的数据存入新的存储片；所述缓存的I帧在I帧出现时缓存，当新的I帧出现时替换缓存的I帧；
Wherein, the R Frame in the buffer zone data is a picture frame only referring to the I Frame.
其中，所述缓冲区数据中的R帧为仅参考I帧的图像帧。
Step S206: Determining whether or not the first frame of the buffer zone data to be stored to the current storage fragment is an I Frame; if so, executing Step S208; otherwise, executing Step S207.
步骤S206：判断所述缓冲区数据中要存入当前存储片的数据的第一帧是否为I帧；若是，执行步骤S208；否则执行步骤S207。
The buffer zone data is stored to the storage area fragment.
将所述缓冲区数据存入存储区域的片。
If the fragment is a newly opened fragment and if the first frame of the data to be stored to the buffer zone data is an R Frame, then an I Frame with reference relation to the first frame is inserted into the newly opened storage fragment, wherein, the R Frame in the buffer zone data is a picture frame only referring to the I Frame.
若所述片为新开辟的片且所述缓冲区数据中要存入存储片的数据的第一帧为R帧，则在所述新开辟的存储片插入与第一帧存在参考关系的I帧；其中，所述缓冲区数据中的R帧为仅参考I帧的图像帧。
The video storage device also comprises an encoder unit 330, configured to encode current pictures according to the encoding method of I Frames when a video storage command is received before the buffer zone data is generated from acquired video.
还包括，编码单元330，用于所述采集视频生成缓冲区数据之前，接收到视频存储命令时，将当前的图像按照I帧的编码方式编码。
So long as the size relation between the storage fragment and buffer zone data is properly adjusted, it is simply a matter of ensuring that I Frame, R Frame, and non-key frame which have reference relation in the buffer zone data stored to the current storage fragment can be stored to the same storage fragment.
只要调整好存储片与缓冲区数据的大小关系，保证要存入当前存储片的缓冲区数据中具有参考关系的I帧、R帧和非关键帧能存入同一个存储片即可。
Because the buffer zone data here does not necessarily begin with an I Frame.
因为这里的缓冲区数据不一定是从一个I帧开始。
Once that buffer zone data must be stored to a new "fragment" and the buffer zone is not provided with an I frame or does not begin with an I frame, then opting to lose the buffer zone data and forcing encoding of an I Frame will destroy the GOP encoding bit stream structure.
如果一旦发现缓冲区中数据需要存入新的"片"，而此时缓冲区中又没有I帧或不以I帧开头，就选择将缓冲区数据丢弃，并且强制编码一个I帧的话，就会打破长GOP编码的码流结构。
