Problems solved by technology

[0012] Since the transmission load in wireless network communication increases, the increased transmission load not only causes transmission delay in the transmission phase, but also causes playback delay in the reception phase
[0013] In this case, there is a problem that the reliability of the entire network system may decrease since image distortion / truncation occurs, and image quality also decreases when the client device 20a reproduces data.

Embodiment Construction

[0032] Now referring to the drawings, a home network system and an operation method thereof according to a preferred embodiment of the present invention will be described in detail. The present invention can be implemented through different embodiments. Since the basic components of the server system for communicating via the wireless network are the same as the conventional components, the same components will not be described in detail.

[0033] figure 2 The server device and the client device in the server system for communicating via a wireless network according to the present invention are briefly shown.

[0034] The server device 100 and a client device 200 implementing the present invention can use a wireless local area network (LAN) or a Bluetooth communication network to wirelessly transmit and receive data based on a radio frequency (RF) signal protocol or a Bluetooth protocol. The invention is not limited to LAN or Bluetooth communication networks.

Abstract

Disclosed are a server system for performing moving picture data communication with a client device over a wireless network, and an operating method thereof. A server device compresses the moving picture data received from an external medium at a variably controlled compression rate according to transmission bandwidth of the current wireless network and an image quality level set by a user in response to a request of the client device. Moreover, the server device transmits the compressed moving picture data to the client device in a wireless fashion. Therefore, transmission delay and playback delay can be avoided and data loss is avoided during a data transmission operation, such that stable data communication can be performed.

Description

Technical field [0001] The present invention relates to a server system for communicating via a wireless network and an operating method thereof, and more particularly to such a server system for communicating via a wireless network and an operating method thereof: by avoiding data reception at a client device Delay and playback delay. At the same time, the server device that transmits the moving image data predicts the current network transmission status and variably controls the compression rate, which can ensure the transmission bandwidth of the data stream and ensure the quality of service (QoS) of the data playback. Background technique [0002] Reference figure 1 Describe a traditional server system that communicates via a wireless network. [0003] A server system communicating via a wireless network includes a server device 10 and one or more client devices, such as client devices 20a and 20b. When the server device 10 and the client devices 20a and 20b transmit and rece...
