The data processing apparatus can include a data processor that is associated with a data capturing device on a stationary object and/or a movable object. The data processor can receive data in a data flow from one or more data sources, wherein the data flow is configured based on a time sequence. Then, the data processor can receive a control signal, which is associated with a first timestamp, wherein the first timestamp indicates a first time. Furthermore, the data processor can determine a first data segment by applying the first timestamp on the data flow, wherein the first data segment is associated with a time period in the time sequence that includes the first time. ## Claims ### Claim 1 A data processing method, comprising: receiving data associated with a time sequence from one or more data sources from one or more capturing devices; storing the received data in a memory; removing a portion of the data stored in the memory after receiving a synchronization signal; and forwarding the removed data to a storage, in response to a control signal for a time period in the time sequence, wherein the time period includes a past portion that equals a maximum image frame number associated with the memory divided by an image speed and a current portion that is a difference between the time period and the past portion. ### Claim 2 (depends on 1) The data processing method of claim 1, wherein the one or more data sources are associated with one or more data capturing devices on at least one of a stationary object or a movable object. ### Claim 3 (depends on 1) The data processing method of claim 1, wherein the received data further comprises at least one of: video data captured using an image sensor, audio data captured using a microphone, or textual data captured using a keyboard. ### Claim 4 (depends on 3) The data processing method of claim 3, further comprising: using one or more encoders to encode the received data; and using a multiplexer for combining the audio data and video data into an audio/video (A/V) data stream. ### Claim 5 (depends on 4) The data processing method of claim 4, further comprising performing one or more image processing operations on the received data before encoding the received data. ### Claim 6 (depends on 1) The data processing method of claim 1, further comprising using one or more communication protocols for receiving the data from the one or more data sources. ### Claim 7 (depends on 1) The data processing method of claim 1, wherein the control signal is based on at least one of pushing a button, a gesture of a being, a movement of an object, a change of a state, a user terminal, a system detector, a state monitor, or a data analyzer. ### Claim 8 (depends on 1) The data processing method of claim 1 wherein the received data contains one or more image frames, and the time sequence is associated with an image frame count. ### Claim 9 (depends on 1) The data processing method of claim 1, further comprising: creating a data segment including a past portion and a current portion. ### Claim 10 (depends on 1) The data processing method of claim 1, further comprising: directing the received data to a user terminal for live view. ### Claim 11 (depends on 1) The data processing method of claim 1, wherein the received data from one or more data sources is at a high definition, and the removed data forwarded to the storage is at a low definition. ### Claim 12 (depends on 1) The data processing method of claim 1, wherein the control signal is received after a switch is turned on. ### Claim 13 A data processing apparatus, comprising: one or more microprocessors; at least one memory storing instructions for execution by the one or more microprocessors in the data processing apparatus; and a data processor, running on the one or more microprocessors, configured to execute the instructions to perform operations comprising: receiving data associated with a time sequence from one or more data sources associated with one or more data capturing devices; storing in a memory the received data; removing a portion of the data stored in the memory after receiving a synchronization signal; and forwarding the removed data to a storage, in response to a control signal, for a time period in the time sequence, wherein the time period includes a past portion which equals a maximum image frame number divided by an image speed and a current portion comprising a difference between the time period and the past portion. ### Claim 14 (depends on 13) The data processing apparatus of claim 13, wherein the one or more data sources are associated with one or more data capturing devices on at least one of a stationary object or a movable object. ### Claim 15 (depends on 13) The data processing apparatus of claim 13, wherein the received data further comprises at least one of: video data captured using an image sensor, audio data captured using a microphone, or textual data captured using a keyboard. ### Claim 16 (depends on 15) The data processing apparatus of claim 15, further comprising: using one or more encoders to encode the received data; and using a multiplexer to combine the audio data and video data into an audio/video (A/V) data stream. ### Claim 17 (depends on 13) The data processing apparatus of claim 13, further comprising using one or more communication protocols for receiving the data from the one or more data sources. ### Claim 18 (depends on 13) The data processing apparatus of claim 13, wherein the storage further comprises at least one of: a storage medium that connects to the memory, or a remote server that connects via a network. ### Claim 19 (depends on 13) The data processing apparatus of claim 13, wherein the data processor is further configured to execute the instructions to perform operations comprising: receiving the control signal based on at least one of pushing a button, a gesture of a being, a movement of an object, a change of a state, a user terminal, a system detector, a state monitor, or a data analyzer. ### Claim 20 (depends on 13) The data processing apparatus of claim 13, wherein the data processor is further configured to execute the instructions to perform operations comprising: receiving the control signal based on a switch being turned on.
