  • Patent number: 8019366
    Abstract: A method for processing a short message and a communication terminal are disclosed. The method includes: receiving a short message; extracting schedule information from the short message after determining that the short message is a schedule short message; and importing the schedule information into a schedule table. The inventive solution enables the communication terminal to automatically identify the schedule short message upon receipt of the short message and imports such schedule short message into the schedule table without manually operating by the user, thereby improving the user experience and increasing the inner value of the communication device.

  • Patent number: 7742651
    Abstract: The detail in an image can be enhanced by selective filtering to separate at least one part of the frequency spectrum of the image from a remaining part of the image. The amplitude of the separated part of the frequency spectrum of image is changed and the amplitude-changed portion is combined with the remaining part of the image. The filtering and/or the change in amplitude is controlled at least in part in response to the content of the image to enhance the detail level of the image where appropriate, while preventing enhancement in areas of the picture where it is likely that artifacts would be generated.

  • Publication number: 20090175435
    Abstract: The disclosure relates to a method and apparatus for determining an internal user for a call center system. The information servicing function provided in the existing communication networks may be utilized in the invention. After a call initiated from an internal user for a call center system to an external user fails, the call center system sends the call information to the external user in a timely manner so that the external user can obtain identification information of the internal user for the call center system in a timely and accurate manner. With the invention, the possibility of reaching the internal user for the call center system is enhanced and thus the interests of the external user and the enterprise entity can be secured.

  • Patent number: 7110457
    Abstract: A system and method for time division multiplexing multiple lower bandwidth signals into a high bandwidth signals such as a high-definition television signal. The invention provides an integrated transmission, distribution and routing signal format in which low-bandwidth signals are embedded in the active video and vertical blanking areas of a high-bandwidth signal. Data from the source data streams, including timing data, is formatted in packets, each packet comprising a plurality of channels. The packets are inserted into the high-bandwidth signal along with a header word providing a ‘data valid bit’ or ‘status bit’ for each of the channels, which identifies valid data words within the packet. The source data streams are accurately reconstituted by de-multiplexing according to header data specifying routing destination, stream ID, stream type, channel usage and stream clock reference for clock recovery at the receiving end.

  • Patent number: 5610942
    Abstract: A method and device for transcoding a digital signal first oversamples the input signal, converts the sampling rate to an oversampled output signal, filters the signal to reduce unwanted bands and decimates the oversampled output signal to produce a transcoded signal having the target sampling rate. This allows the conversion to be implemented in the composite domain, requiring a single sampling rate converter, and significantly reduces the complexity of the filter required to filter the output signal.
