摘要： Disclosed is a method for providing information about multimedia contents in a multimedia service system. If a mobile communication terminal receives a request for content information from a user while reproducing received multimedia data according to a VOD service, the mobile communication terminal provides information related to a content request time to a content information providing server. Alternatively, if the mobile communication terminal receives a request for content information from a user while reproducing the received multimedia data according to a VOD service, the mobile communication terminal may provide the content information providing server with frame information of the content information request time. Accordingly, the content information providing server searches a content information database with reference to the frame information or the content information request time. Then, the content information providing server transmits several pieces of information searched according to the corresponding content information request time to the terminal.

摘要： An MPEG-4 encoder utilizing an H.263 multimedia chip. The MPEG-4 encoder includes a DC (Direct Current) predictor for predicting a DC component of the image frame encoded by an H.263 standard upon receiving a prescribed MPEG-4 quantization value, and an MPEG-4 reconstruction image memory for converting the H.263 reconstruction image into an MPEG-4 reconstruction image, and storing the MPEG-4 reconstruction image. The MPEG-4 encoder removes spatial redundancy from source image data entered in frame units using a prescribed H.263 quantization value, predicts a DC component of an image frame having no spatial redundancy using a prescribed MPEG-4 quantization value, performs a VLC (Variable Length Coding) process on the image frame using the predicted DC component, and outputs the VLC-processed image frame in the form of an MPEG-4 bit stream. The MPEG-4 encoder reconstructs the image frame having no spatial redundancy, stores the reconstructed image frame, converts the reconstructed image frame into an MPEG-4 frame, stores the MPEG-4 frame, compares the stored image frame with a newly-entered next frame, and removes temporal redundancy according to a result of the comparison.

摘要： Disclosed is a method for ensuring the integrity of a container to be transmitted to a Digital Video Broadcasting-Handheld (DVB-H) terminal. A DVB-H server divides a container in which data required to deliver broadcasting information is included into one or more sections, extracts a Cycle Redundancy Check (CRC) value related to data of each section, and then creates profile information of the container. The created profile information of the container is used to check the integrity of the container, and is transmitted following the addition of the created profile information to a header part of the container. Hence, the terminal compares data of an actually received container with data of a container which has to be received on the basis of the profile information related to the container, and determines if the data included in the container is lost.

摘要： An H.263/MPEG video encoder using DCT in a mobile communication terminal. The H.263/MPEG video encoder controls a quantization value using granularity analysis by motion estimation and efficiently controls bit rates. The H.263/MPEG video encoder performs DCT for an input image (N−1), quantizes the input image to output the input image as a video stream, decodes the quantized signal by means of inverse quantization (IQ) and inverse discrete cosine transform (IDCT), and performs motion estimation in comparison with a next input image (N). The H.263/MPEG video encoder includes a granularity analyzing section for analyzing granularity using a result of performing the motion estimation, a granularity control section for controlling a quantization value for the quantization according to an analysis result of the granularity analyzing section, and a frame rate control section for controlling a frame speed of an output of the video stream.
