Preventing overflow in a buffer by halting an encoder/ compressor

摘要

Disclosed is a server system for performing communication over a wireless network. At least one client device transmits and receives data over the wireless network. A server device performs a state monitoring or controlling operation for the at least one client device. In the server device, an encoder compresses and encodes data to be transmitted that includes a double buffer storing the encoded data. A network renderer transmits the data encoded by the encoder to a corresponding client device over the wireless network. A buffer manager detects an overflow of the buffer storing the data encoded by the encoder and issues a control signal for pausing an encoding/compressing operation when the overflow is detected. Therefore, the server system can avoid data loss and system shutdown caused by transmission delay and can ensure stability of the server system performing communication with a wireless network. The buffer size may be adjusted.
