  • Publication number: 20100179816
    Abstract: A digital lifetime record and display system is provided. The digital lifetime record and display system includes a data input module, a database and a lifetime display module. Time and corresponding image related data are inputted through the data input module and respectively saved as the time related data and image paths in the database. Additionally, the lifetime display module has a timeline unit which displays time points corresponding to the time related data and a time display unit and an image display unit which both correspond to the time points. Thus, the lifetime display module can display time related data and a representative image which is one of the corresponding image related data. The digital lifetime record and display system can build up a personal image timeline for memorizing or sharing.

  • Publication number: 20090320056
    Abstract: A system of using a set-top box to obtain ad information includes a remote control, a set-top box, a program system server, and an advertising server. A first ad request corresponding to a target ad is transmitted to the set-top box via the remote control so as to obtain ad information of the target ad. A second ad request corresponding to the first ad request received is produced and transmitted to the program system server by the set-top box. A third ad request corresponding to the second ad request received is produced and transmitted to the advertising server by the program system server. The advertising server obtains a user's contact information and the ad information of the target ad according to the third ad request and transmits the ad information to the user. Hence, the user obtains the ad information of the target ad conveniently by the set-top box.
