Cloud streaming service system, data compressing method for preventing memory bottlenecking, and device for same
The present invention relates to a cloud streaming service system, a data compressing method for preventing memory bottlenecking, and a device for same and, particularly, to a technology that: can prevent memory bottlenecking by compressing data when the transmitted amount of original buffer data exceeds a reference value, based on a system memory bandwidth; can provide a cloud streaming service by applying an order of priority by service type according to whether the processing limit, for the number of simultaneous connecting entities that can be processed by one server, is reached during a cloud streaming service; and can test whether a sever that provides a cloud streaming service is operating normally and whether a connection error occurs.
1. A cloud streaming server comprising:
a capture unit configured to capture a cloud streaming service screen;
an encoding unit configured to load the captured cloud streaming service screen from a buffer for temporarily storing the captured cloud streaming service screen, and to encode the loaded cloud streaming service screen;
a communication unit configured to transmit the encoded cloud streaming service screen to a terminal device; and
a compression unit configured to determine whether a bottleneck occurs in the buffer, and to compress the cloud streaming service screen depending on a determination result.
2. The cloud streaming server of claim 1 , wherein the compression unit determines, based on a data storage rate of the buffer, whether the bottleneck occurs.
3. The cloud streaming server of claim 2 , wherein if the data storage rate of the buffer exceeds a predetermined reference storage rate, the compression unit determines that the bottleneck occurs in the buffer.
4. The cloud streaming server of claim 3 , wherein the compression unit selects one or more identical frames, which are identical with previous frames, from among frames corresponding to the cloud streaming service screen, and converts the one or more identical frames into a flag for indicating that the one or more identical frames are identical with the previous frames.
5. The cloud streaming server of claim 4 , wherein the compression unit encodes a format of image data corresponding to the cloud streaming service screen into a format to reduce capacity.
6. The cloud streaming server of claim 1 , wherein the compression unit determines, based on a data increase rate of the buffer, whether the bottleneck occurs.
