Problems solved by technology

When the data of the frame image buffered in the client decreases, the occurrence of frame loss can be prevented by reducing the data transfer rate, but this causes deterioration of the image quality

Abstract

The present invention relates to a server device and an information processing method. Specifically, there is provided a server device including a stream processing unit configured to generate frame images in real time, encode the frame images to generate encoded data, and convert the encoded data via a network, a client device, and a controller. data is sent to a client device, the client is configured to decode the encoded data and output the frame image, the controller is configured to receive output from the client device with the frame image in the client device time-related information and controls the processing time of the frame image in the stream processing unit so that a predetermined relationship is maintained between the output time and the processing time.

Description

technical field [0001] The present disclosure relates to a server device and an information processing method. Background technique [0002] In a streaming system in which video or audio is distributed from a server to a client via a network, for example, there is a change in data transmission rate (jitter) due to a change in the communication state of the network. Frame loss may occur when the communication state in which the data transfer rate is lower than the designed value continues. That is, frame loss means that a frame image that should have been displayed under normal circumstances is not displayed on the client computer due to a delay in data transmission. [0003] In order to prevent the occurrence of frame loss, for example, a technique as disclosed in Japanese Unexamined Patent Application Publication No. 2011-119971 has been proposed. In these techniques, the data transfer rate of the server is changed according to the buffer state of the data of the frame im...
