| 20080320536 | System and Method for Providing Personalized Datat Broadcasting Service, User Terminal and Method for Using Personalized Data Broadcasting Service, and Data Broadcasting Application Structure Therefor - Provided is a system and method for providing a personalized data broadcasting service, a user terminal and method for using a personalized data broadcasting service, and a data broadcasting application structure therefor, to provide a desired broadcasting service to a viewer anytime and anywhere by using diverse terminals. The user terminal includes: a data broadcasting middleware for receiving unidirectional data broadcasting contents transmitted through a broadcasting network; a personalized broadcasting middleware for receiving bidirectional data broadcasting contents transmitted through a communication network; and a contents storing means for storing the unidirectional data broadcasting contents and the bidirectional data broadcasting contents, wherein the data broadcasting middleware executes the unidirectional data broadcasting contents and bidirectional data broadcasting contents. The present invention provides a fast and stable data broadcasting service through a communication-broadcasting integration personalized data broadcasting service. Also, it provides diverse data broadcasting services to each user through a targeting personalized data broadcasting service. | 12-25-2008 |
| 20100171882 | METHOD FOR TUNING CODING RATE AND APPLYING UNEQUAL ERROR PROTECTION FOR ADAPTIVE VIDEO TRANSMISSION, AND VIDEO TRANSMISSION/RECEPTION APPARATUS USING THE METHOD - Provided are a method of tuning a coding rate and applying an unequal error protection for an adaptive video transmission, and a video transmission/reception apparatus using the method. The video transmission apparatus may include: a coding rate tuner to predict, as a channel capacity of a subsequent channel interval, an estimated channel capacity value fed back from the video reception apparatus, and to tune video and channel coding rates within the predicted channel capacity; a video encoder to perform video encoding of video frames at the tuned video coding rate, and to generate a video packet; and a forward error correction (FEC) encoder to apply the unequal error protection based on a length of the video packet and a type of the video frames included in the video packet, and to perform channel encoding of the video packet at the tuned channel coding rate to generate a bitstream. | 07-08-2010 |
| 20110145697 | DEVICE FOR SCENE PRESENTATION OF STRUCTURED INFORMATION - A method for performing presentation with reference to structured information existing in an internal or external is defined.
