Abstract
A data transmitting method in a thin client network system including a thin client, and a server connected to the thin client through a network. An application program is executed on the server in response to a request of the thin client and results of the execution are transmitted to the thin client as graphic data. If a determination is made that the application program activated by the thin client includes moving picture data, the moving picture data is compressed with a lossy compression algorithm and data other than the moving picture data is compressed with a lossless compression algorithm before the compressed data is transmitted from the server to the thin client. Thus, a size of data transmitted from the server to the thin client is efficiently decreased.
Claims12
A method of transmitting data in a thin client network system comprising a thin client, and a server connected to the thin client through a network, the server being provided with at least one application program, the server activating and executing an application program in response to a request of the thin client, the method comprising:
- determining whether the activated application program includes moving picture data;
- compressing the moving picture data with a lossy compression algorithm and nonmoving picture data with a lossless compression algorithm if a determination is made that the active application program includes the moving picture data;
- and
- transmitting the compressed data from the server to the thin client.
A thin client network system comprising:
- a network;
- a thin client;
- a server connected to the thin client through the network, the server provided with at least one application program, the server activating and executing an application program in response to a request of the thin client, and transmitting results from the execution of the application program to the thin client;
- and
- a control part provided in the server, and which:
- determines whether the application program activated by the thin client includes moving picture data, and
- controls the moving picture data to be compressed by a lossy compression algorithm and non-moving picture data to be compressed by a lossless compression algorithm in response to the determination that the activated application program includes the moving picture data.
A server for executing a client request in a thin client network, the server comprising:
- an application program;
- a central processing unit which runs the application program in response to a client request;
- and
- a control part which:
- determines whether a result of running the application program requested by the thin client includes moving picture data, and
- controls compression of the moving picture data by a lossy compression algorithm and compression of non-moving picture data by a lossless compression algorithm, if the determination is made that the requested application program includes the moving picture data,
A method of operating a server in a thin client network, the method comprising:
- receiving a request to activate an application program from a thin client;
- running the application program;
- determining whether a result of running the application program requested by the thin client includes moving picture data,
- controlling compression of the moving picture data by a lossy compression algorithm and compression of non-moving picture data by a lossless compression algorithm, if the determination is made that the result of running the application program includes moving picture data;
- and
- transmitting the compressed data to the client.
