CTOnews.com October 30 news, the State Administration of Radio and Television issued a notice today, in accordance with the radio and television and network audio-visual industry standard formulation procedure requirements and planning arrangements, the State Administration of Radio and Television organized relevant units to prepare "immersive terminal general technical requirements", "cloud game general technical requirements", "free visual angle video system technical requirements" industry standard The draft that has been examined and approved by the National Technical Committee for Radio, Film and Television Standardization is now publicized.

CTOnews.com found from the approval draft of the industry standard "General Technical requirements for Cloud Games" that the document defines the overall technical architecture of cloud games, as well as the technical requirements for cloud game platforms, networks, cloud game terminals and cloud game security, and puts forward requirements for cloud game platforms and cloud game terminals for minor users.

The drafters of the standard include:

Radio and Television Research Institute of the State Administration of Radio and Television, Tencent Science and Technology (Shanghai) Co., Ltd., China Radio and Television Network Group Co., Ltd., Migu Interactive Entertainment Co., Ltd., Yuanjing Sheng Sheng (Beijing) Technology Co., Ltd., Zhejiang Huasu Radio and Television Network Co., Ltd., Jiangsu Radio and Television Cable Information Network Co., Ltd., China Radio and Television Hunan Network Co., Ltd., Guoguang Oriental Network (Beijing) Co., Ltd., Qingdao Xifa Radio and Television Technology Co., Ltd., Mutual Shadow Technology (Beijing) Co., Ltd., Beijing decision Digital Technology Co., Ltd., Beijing and Chuangmore Technology Co., Ltd.

The overall technical architecture of cloud games includes four parts: cloud game platform, network, cloud game terminal and cloud game security.

The cloud game platform receives user operation instructions, completes the operations of game picture rendering, audio and video codec and game push, and transmits the game content in the form of audio and video stream to the terminal on the user side for presentation.

Users use the terminal to send operation instructions to the cloud game platform to render the game screen, push the game and so on.

Cloud game security runs through all aspects of cloud games, realizing the protection of user information, account information, game behavior information and so on.

The file shows that the cloud game platform should have the image rendering capability based on independent GPU, should meet the video format requirements in GY / T 353-2021, should have the picture rendering capability of 1080p / 50fps or 1080p / 60fps, and should support 2K / 60fps, 4K / 50fps, 4K / 60fps and so on.

In terms of network, according to the quality of the game screen, the requirements for the network are also different, for example, 1080p 50/60fps requires downlink bandwidth of 20Mbps.

In terms of cloud game terminals, the file requires the device to meet the following hardware configuration requirements:

CPU: no less than 4 processing cores, and the highest frequency is not less than 1.5GHz

Memory: at least 1GB, 2GB or above is recommended

Storage: 4GB or above, high speed eMMC or UFS.

The decoding delay of cloud game terminals should be within 20ms when the frame rate is 30fps, and within 10ms when the frame rate is 50/60fps. Each frame rendered by the terminal device and the sound played should be strictly synchronized, and the synchronization time of sound and picture should not exceed + 90ms and-185ms, where a positive value indicates that the sound is ahead of the image, and a negative value means that the sound lags behind the image. The extra operation delay should not be greater than 150ms, and should not be greater than 100ms.

For minor users under the age of 18, the cloud game platform shall provide the following protection features:

Have the ability to manage user accounts with real names

Have the ability to control the duration and duration of games used by minors

Have the ability to manage the game consumption of minor users

Have the ability to notify the guardian in at least one way.
