Abstract

Content is created at a first location using a video camera or other device. At least a subset of the created content is stored in non-volatile storage at the first location. At least a portion of the content stored in the non-volatile storage is transmitted to a remote entity via a network in response to a trigger. For example, a video camera may send video data to a server or other client. If the network becomes unavailable, the camera will store the video in a local flash memory and when the network becomes available, the camera can transmit the video from the flash memory to the server or other client. Alternatively, the camera may transmit low resolution video to the server while storing a high resolution version of the video in the local flash memory. If a trigger event occurs, the camera will then send the appropriate high resolution video the local flash memory to the server. In another alternative, video (or other content) transferred to a mobile device is stored and paused during a telephone call (or other function).
