Disclosed is a method of generating a reference frame of a video CODEC for implementing motion compensation through motion estimation. The present invention is to increase compression efficiency by additionally creating various reference frames applied to an intentional motion blur and a deblur filtering, and selecting reference frame having small residual frame data during execution of the motion estimation as final reference frames among original reference frames and various reference frames additionally created.

Disclosed herein is an interactive broadcasting system. The interactive broadcasting system includes a web server, a content providing server, a streaming server, a broadcast control server, and a content control server. The web server provides a web page through the Internet and controls a web connection. The content providing server provides content. The streaming server streams the content to the mobile terminal, and receives messages transmitted from the mobile terminal. The broadcast control server manages the broadcast schedule of the content and generates details of the picture construction. The content control server generates a picture depending on the details of a picture construction, and performs picture combination by overlaying the generated picture on a content picture provided by the content providing server, and transmits the combined picture to the streaming server, thus allowing the combined picture to be streamed to the mobile terminal by the streaming server.
摘要:
If a recipient's mobile communication terminal supports a multimedia messaging service (MMS), previously stored MMS data are read out. If not so, only short message service (SMS) data among the MMS data are read out. The retrieved MMS or SMS data are transmitted to the recipient's mobile communication terminal via a mobile communication repeater. When text data are input through a sender's mobile communication terminal while the transmission of a message is requested by the sender's mobile communication terminal, the text data are transmitted together with the MMS or SMS data to the recipient's mobile communication terminal.
摘要:
A compression encoding method which, when performing data conversion using the fact that when data is converted into frequency components, the human eye is sensitive to components close to low frequency components and insensitive to components close to high frequency components, configures a filter in which importance is placed on DC data and its adjacent filter coefficients, calculates the cost for a conversion block which has undergone conversion and quantization, which is required for the data removal of compression encoding using the filter, determines data targets to be removed using the calculated cost and set reference values, and removes the corresponding data, thereby reducing the amount of data to be compressed and therefore increasing compression efficiency without influencing image quality.

Disclosed is a method for generating a motion search area of a video CODEC for implementing motion compensation through motion estimation as a unit of block. Compression efficiency can be further improved by additionally creating various reference frames by an intentional motion blur and a deblur filter, filtering a motion search area using a motion blur filter and a motion deblur filter as a unit of block which is a unit of video coding, and selecting reference frame having small residual frame data during execution of the motion estimation as final reference frames among original reference frames and various reference frames (motion search areas) additionally created.
