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.
摘要:
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.
