20180213297 | SELECTIVELY DELAYING CONTROL WORD DELIVERY FOR PIRACY IDENTIFICATION - Systems, devices and automated processes detect piracy of broadcast television signals through selective delay of decrypted code words that are used to render satellite or other received television signals. Smart cards or similar access control hardware are programmed to selectively delay delivery of cryptographic code words based upon the identity of the receiver device. The delayed delivery of the code words produces intentional glitches in the content rendered by the receiver, thereby allowing viewers of the rendered content to ascertain the identity of the device. | 2018-07-26 |
20180213298 | RECEIVING APPARATUS, TRANSMITTING APPARATUS, AND DATA PROCESSING METHOD - This technology relates to a receiving apparatus, a transmitting apparatus, and a data processing method for displaying emergency information communicated in an emergency at appropriate positions. | 2018-07-26 |
20180213299 | APPARATUS AND METHOD FOR TRACKING TEMPORAL VARIATION OF VIDEO CONTENT CONTEXT USING DYNAMICALLY GENERATED METADATA - There are provided an apparatus and method for tracking temporal variation of a video content context using dynamically generated metadata, wherein the method includes generating static metadata on the basis of internal data held during an initial publication of video content and tagging the generated static metadata to the video content, collecting external data related to the video content generated after the video content is published, generating dynamic metadata related to the video content on the basis of the collected external data and tagging the generated dynamic metadata to the video content, repeating regeneration and tagging of the dynamic metadata with an elapse of time, tracking a change in content of the dynamic metadata, and generating and providing a trend analysis report corresponding to a result of tracking the change in the content. | 2018-07-26 |
20180213300 | METHOD AND APPARATUS OF BITSTREAM RANDOM ACCESS AND SYNCHRONIZATION FOR MULTIMEDIA APPLICATIONS - A method and device for switching Representations are disclosed. On the server side, leading-picture information associated with leading pictures in an open GOP (group of picture) is signalled in a media presentation description. Each leading picture corresponds to one picture preceding a RAP (Random Access Picture) picture in a segment in an output order and being coded depending on the RAP picture. At the client side, an original Representation and a target representation are received and the leading-picture information for the target Representation is determined from the media presentation description received. A switched presentation is presented, where the switched presentation switches from the original Representation to the target Representation by switching presentation from pictures in the original Representation to pictures in the target Representation at a stream access point (SAP) corresponding to the RAP picture in one segment of the target representation determined according to the leading picture information. | 2018-07-26 |
20180213301 | MEDIA PLAYBACK APPARATUS AND METHOD FOR SYNCHRONOUSLY REPRODUCING VIDEO AND AUDIO ON A WEB BROWSER - A media playback apparatus and a method for synchronously reproducing video and audio on a web browser are provided. In the media playback apparatus, audio is buffered to be outputted at a time point at which video is outputted, thereby synchronizing the outputs of video and audio. The media playback apparatus may output the video in synchronization with the audio even when video and audio are decoded by different decoders. Therefore, it is possible to implement a decoder separately from a decoder embedded in a web browser in a non-plug-in environment, thereby reducing the dependency on the codec format of the media. | 2018-07-26 |
20180213302 | RFID Status Monitor For High Voltage and Remote Electric Power Systems - A remote blade closing detector switch is positioned on or near the jaws of an electric power disconnect switch, where proper seating of the blade in the jaws activates a detector switch. An extended conductor lead electrically connects the detector switch an RFID placed in a convenient reading location. The detector switch via the extended conductor is configured to regulate (i.e., switch on and off) a data signal, power to the antenna of the RFID tag, or the power supply to the RFID tag as mechanisms for enabling and disabling the tag to report a status indicator. | 2018-07-26 |
20180213303 | Low Delay Low Complexity Lossless Compression System - A method for compressing data is disclosed. The method may include receiving data from one or more data sources. The method may also include selectively classifying the data into one or more data streams, the one or more data streams including at least PCM-encoded data and image data. The method may further include separately compressing the PCM-encoded data and the image data into first and second compressed bit-streams. The method may also include shuffling the first and second compressed bit-streams. | 2018-07-26 |
