Methods and systems for automatically and efficiently categorizing, securely transmitting, and managing multimedia contents generated from a network connection enabled digital data generating device by way of multimedia transcoding, compression, and/or classification. Content similarity between multimedia data units with one unit corresponding to one image, one video frame, or one audio frame is first detected and identified, and then used to help encode conditionally one unit given another. Based on the identified content similarity and/or the resulting compression efficiency, these multimedia units are automatically categorized in terms of their contents along with their locations, occasions, events, and/or features. Whenever network connections selected by a user are available, these encoded and categorized multimedia data units along with their metadata containing side information including their locations, occasions, events, features, and other information specified by the user are then automatically and securely transmitted to networks, cloud servers, and/or other network connected devices. |
