Abstract: An improved technique transmits data acquired with a smartphone to a remote storage server while the smartphone acquires additional data. For example, a user wishing to record a live scene with a smartphone camera establishes a connection with a remote storage server with which the user has an account. Once the connection is established and the user begins recording the live scene, the smartphone generates video data from images of the recorded live scene and places some predetermined amount of acquired video data into a data packet. The smartphone then sends the data packet to the remote storage server over the connection. As the data packet is being sent, the smartphone places another predetermined amount of acquired data. Because the predetermined amount of data is very small, the net amount of data stored is limited by the available space on the remote storage server rather than the local hard drive of the smartphone.
