数据缓冲区

The combination of the two can achieve rapid, accurate, and complete video storage, avoiding loss of video data due to the condition that the first frame of the data buffer zone is a reference object.

两者的结合，能够实现视频存储的快速准确完整，避免了因为数据缓冲区的第一帧不是参考对象而放弃视频数据。

Otherwise, a new "fragment" is opened and the video encoding data of the data buffer zone is stored to the new "fragment".

否则，就会开辟一个新的"片"，把数据缓冲区中的视频编码数据存入这个新的"片"当中。

If the sum does not exceed the threshold value, the video encoding data of the data buffer zone is stored to the current "fragment".

如果还未超过，则将数据缓冲区中的视频编码数据存入当前"片"；

Figure 3 is a flow diagram of video data storage processes in the prior art. As seen in the figure, during the process of video data storage, the storage equipment opens a data buffer zone used for temporarily storing the latest segment of video encoding data.

图3是现有技术中视频数据存储过程的流程图，如图所示，在视频数据的存储过程中，存储设备会开辟一个数据缓冲区，用于暂时存放最新的一段视频编码数据。

Another approach to achieving the effect is as shown in Figure 9. The data buffer zone is divided into multiple sub-zones, among which two sub-zones are configured to buffer I Frames, while other sub-zones are configured to buffer an R Frame and a P Frame with reference relation to the R Frame.

另一种实现方式如图9所示，数据缓冲区中分为多个子分区，其中两个子分区用于缓存I帧，另外子分区用于缓存一个R帧及与该R帧存在参考关系的P帧。

The sub-zones of the data buffer zone buffering the two I Frames respectively store the current I Frame and the earlier I Frame.

数据缓冲区的两个缓存I帧的子分区分别存储有当前I帧和较早I帧。

The sub-zones of the data buffer zone buffering the two I Frames respectively store the current I Frame and the earlier I Frame. When an I Frame is acquired in a data buffering process, the earlier I Frame is replaced.

数据缓冲区的两个缓存I帧的子分区分别存储有当前I帧和较早I帧，数据缓冲过程中采集到I帧，将较早I帧替换。

If I Frames exist, the I Frames are acquired to the data buffer zone.

如果I帧存在的话，将该I帧采集到数据缓冲区中。

In State 1, Rn-1 and a subsequent P Frame thereof have already been buffered, and are stored to the storage fragment at this point, and at the same time Rn and the subsequent P Frames thereof are buffered to the data buffer zone.

在状态1中，Rn-1及其后续P帧已经缓冲完成，此时将其存储到存储片中，同时Rn及其后续P帧向数据缓冲区中缓冲。

In the embodiment, multiple data buffer zones can be configured. The data in data buffer zones are to the greatest degree possible near to the largest value of the data buffer zone, and the data of the data buffer zone is stored to the storage fragment.

在本实施例中，可以设置多个数据缓冲区，在数据缓冲区中的数据尽可能接近数据缓冲区的最大值，将数据缓冲区的数据存入存储片中。

Under random state, it is possible the P Frame quantity following an R Frame could be relatively large. In order to guarantee that all subsequent P Frames can be buffered to the data buffer zone, the storage space of the data buffer zone is configured to be sufficiently large.

在随机状态下，有可能R帧后续的P帧的数目较大，为了保证所有的后续P帧能缓冲到数据缓冲区，数据缓冲区的存储空间设置得足够大。
