Description

Technical Field

[0001] The present invention relates to the technical field of game systems, and particularly to an ultra-low-latency game system.

Background Art

[0002] With the development of science and technology and the popularization of smart terminals such as computers, smartphones, and game control devices, the functions of smart terminals have become increasingly rich, the development of the game industry has become rapid, the types of games have become increasingly numerous, and particularly, operation-based games are popular among users, and more and more game systems have begun to appear. Players' requirements for the performance of game control devices, smart terminals, and auxiliary electronic devices are also becoming increasingly high.

[0003] Conventional game control devices generally use USB, Bluetooth, etc. for signal transmission. However, the latency of Bluetooth communication usually exceeds 100 ms, and Bluetooth signal transmission causes mutual interference, data loss, etc., resulting in a large latency in transmission. The latency of USB communication is all 8 ms or more, generally 8 - 16 ms, and the communication interval for one round trip between the game host and the game control device may reach 16 ms. Furthermore, the game host processes information every 16 ms, and there is a problem of long latency. Therefore, for conventional wired or wireless communication game control devices, there are problems such as long communication time with the game host and latency in data transmission, which further affect the game experience of users. Thus, there is an urgent need for a game system capable of ultra-low latency.

[0019] Hereinafter, in order to explain the technical solution according to the present invention, specific examples will be used for explanation below, and only the parts related to the embodiments of the present invention will be shown.

[0020] Example 1 As shown in FIGS. 1 to 4, the present invention provides an embodiment of an ultra-low-latency game system. This ultra-low-latency game system includes a game host 1 and at least one game control device 2 communicably connected to the game host 1. Each game control device 2 is communicably connected to the game host 1 (either by a wired communication connection or a wireless communication connection). Specifically, the game host 1 includes a first ultra-low-latency communication module 11, the game control device 2 includes a second ultra-low-latency communication module 21, and the game host 1 is communicably connected to each game control device 2 with ultra-low latency by the first ultra-low-latency communication module 11 and the second ultra-low-latency communication module 21. The delay period of the ultra-low latency is set by the HID descriptors of the first ultra-low-latency communication module 11 and the second ultra-low-latency communication module 21. The delay period of the ultra-low latency is 0.2 ms to n + 0.2 ms or less, and n is an integer in the range of 1 to 8.

[0021] As an optional embodiment, the first ultra-low-latency communication module 11 may be built-in (i.e., directly provided inside the game host 1), or may be an external type. That is, the game host may further include a USB dongle receiver 12, and the first ultra-low-latency communication module 11 is provided on the USB dongle receiver 12. Thereby, the general compatibility of the present invention becomes higher and can be adapted to any game host 1. Therefore, the game experience of existing game hosts can be significantly improved.

[0022] In an optional embodiment, the first ultra-low latency communication module 11 includes a first UWB module 111 and / or a first USB module 112 (i.e., it may be just a UWB module, just a USB module, or include both a UWB module and a USB module), in which case the second ultra-low latency communication module 21 may include a second UWB module 211 and / or a second USB module 212, i.e., the game host 1 may perform an ultra-low latency wireless communication connection using UWB technology and the game control device 2, or the game host 1 may perform an ultra-low latency wired communication connection using USB technology and the game control device 2.

[0023] In an optional embodiment, the first ultra-low latency communication module 11 includes a first UWB module 111, in which case the second ultra-low latency communication module 21 includes a second UWB module 211, and the ultra-low latency delay period of the wireless communication between the first UWB module 111 and the second UWB module 211 is 0.2ms to n+0.2ms or less, where n is an integer in the range of 1 to 8. That is, the game host 1 and the game control device 2 achieve an ultra-low latency wireless communication connection of 0.2ms to n+0.2ms using UWB technology, significantly improving the gaming experience.

[0024] In an optional embodiment, the first ultra-low latency communication module 11 includes a first USB module 112, in which case the second ultra-low latency communication module 21 includes a second USB module 212, and the wired communication between the first USB module 112 and the second USB module 212 is an interrupt transmission mode (i.e., polling transmission mode) with an ultra-low latency period of 0.2ms to n+0.2ms or less, where n is an integer in the range of 1 to 8. In other words, the game host 1 and the game control device 2 achieve an ultra-low latency wired communication connection of 0.2ms to n+0.2ms using USB technology, significantly improving the gaming experience.

[0025] Furthermore, both the first UWB module 111 and the second UWB module 211 are wireless carrier communication technologies using a frequency bandwidth of 1 GHz or higher, and transmit data using nanosecond-level non-sinusoidal narrow pulses. They have advantages such as not being sensitive to channel fading, having a low power spectral density of the transmitted signal, a low cutoff rate, low system complexity, and centimeter-level positioning accuracy, and can increase the transmission speed of signals between devices and significantly reduce latency.

[0026] In an optional embodiment, the game control device 2 further includes a signal acquisition module 22 and a buffer 23. The signal acquisition module 22 periodically scans and collects the key state signals of each game key 27 of the game control device 2 at each scan cycle, stores them in the buffer 23 in real time, and transmits them to the game host 1 by the second ultra-low latency communication module 21 within the transmission cycle. Specifically, the transmission cycle is the duration for which the key state signals are transmitted, which is generally 200 μs (i.e., 0.2 ms, and 200 μs is required for transmission due to hardware processing limitations), and the delay cycle is the sum of the transmission cycle and the cache cycle. Specifically, the delay cycle, transmission cycle, cache cycle, and scan cycle are all set by the HID descriptors of the first ultra-low latency communication module 11 and the second ultra-low latency communication module 21.

[0027] In any embodiment, since the duration of a user's normal key action is longer than 0.2 ms, if the duration of a key action is less than 0.2 ms, it may be determined to be jitter and ignored. After the user presses a key, the signal acquisition module 22 can acquire the key state signal in a timely manner, acquire the level signal (i.e., the key state signal) that is still continuing in the cache cycle, and store it in the cache 23 in real time. If a key is pressed during the transmission cycle, the key state signal may be acquired after the transmission cycle and stored in the buffer 23 in real time. That is, the key state signal may only be stored in the buffer 23 during the transmission cycle if it is not possible to store the key state signal in the buffer 23, and the key state signal in the buffer 23 is transmitted to the game host 1.

[0028] As shown in Figure 2, using this figure as an example, when n is 1, the delay period is 1 ms, the scan period is 100 μs, the buffer period is 800 μs, and the transmission period is 200 μs. Furthermore, the delay time for the ultra-low delay does not exceed 0.2 ms to 1.2 ms, that is, the maximum delay time for the ultra-low delay is 1.2 ms, and the minimum delay time for the ultra-low delay is 0.2 ms. For a more accurate explanation, we define the concepts of a cache start time, which is 0 μs from the start of the cache period; a cache end time, which is 800 μs from the start of the cache period and equivalent to the transmission start time; a transmission start time, which is 0 μs from the start of the transmission period; and a transmission end time, which is 200 μs from the start of the transmission period. When n is 8, the delay period is 8 ms, the scan period is 100 μs, the cache period is 7800 μs (i.e., 7.8 ms), and the transmission period is 200 μs. Furthermore, the ultra-low latency delay time is between 0.2ms and 8.2ms or less, meaning that the maximum ultra-low latency delay time is 8.2ms and the minimum ultra-low latency delay time is 0.2ms.

[0029] As shown in Figure 2, the HID descriptors of the first ultra-low latency communication module 11 and the second ultra-low latency communication module 21 set an ultra-low latency delay period, with the ultra-low latency delay period being 1 ms. The signal acquisition module 22 of the game control device 2 periodically scans and collects the key state signals of each game key 27 of the game control device 2 (one scan period every 100 μs), stores them in the buffer 23 in real time, and transmits them to the game host 1 by the first ultra-low latency communication module 11 within the transmission cycle. During the transmission cycle (i.e., the period from the start of transmission to the end of transmission), the key state signals cannot be stored in the buffer 23, and the key state signals within the transmission cycle can only be stored in the buffer 23 if the key state signals in the buffer 23 have been transmitted to the game host 1.

[0030] More specifically, if the game control device 2 caches the key state signal collected at the start of the transmission cycle in buffer 23 in a timely manner, it transmits it to the game host 1 within the transmission cycle, with a minimum delay of 0.2 ms. If the game control device 2 caches the key state signal collected at the start of the cache cycle in buffer 23 in a timely manner, it transmits it to the game host 1 within the transmission cycle, with a delay of 1.0 ms. If the game control device 2 does not cache the key state signal collected during the transmission cycle of the previous delay cycle in buffer 23 in a timely manner, it transmits it to the game host 1 within the transmission cycle of the current delay cycle, with a maximum delay of 1.2 ms.

[0031] This invention realizes ultra-low latency communication between a game host and a game control device, drastically reducing the communication delay time from the game control device to the game host to within 0.2ms to 1.2ms. This represents a significant reduction in latency compared to the conventional 16ms delay, greatly improving transmission efficiency and enhancing the game operation experience.

[0032] Example 2 As shown in Figures 1 to 4, based on Embodiment 1, the game control device 2 further includes a key control positioning module 24 and a switching module 25. The second UWB module 211 is used to position the relative position of the game control device 2, and the key control positioning module 24 is used to position the absolute position of the game control device 2. Specifically, the key control positioning module 24 may be the up, down, left, right keys, rockers, etc., of the game control device 2, and is used to control the direction and position of game operation of the game host 1. The switching module 25 switches the positioning mode for the second UWB module 211 or the key control positioning module 24 according to the game type of the game host 1, and further determines whether it is a UWB positioning mode or a conventional positioning mode. In other words, the switching module 25 allows mutual switching between the second UWB module 211 and the key control positioning module 24.

[0033] Specifically, when the positioning mode of the game control device 2 is switched to UWB positioning mode, the game host 1 is wirelessly connected to the second UWB module 211 of the game control device 2 by the first UWB module 111, and each of the second UWB modules 211 determines the distance between each game control device 2 and each of the game hosts 1, that multiple game control devices 2 are wirelessly connected to each other by the second UWB modules 21, and the distance between the game control devices 2.

[0034] In an optional embodiment, if each game control device determines that its positioning mode is a UWB positioning mode, it transmits a positioning data signal to the second UWB module of the other game control device via the second UWB module at each delay period, records the transmission time, waits for the other game control device to transmit a feedback signal of the received positioning data signal, records the reception time, calculates real-time relative position information with each of the other game control devices based on the time difference between the reception time and the transmission time, and the transmission speed of the data transmission, and each game control device collects the corresponding key state signal and real-time relative position information and transmits them to the game host in a timely manner.

[0035] In an optional embodiment, if the game control device determines that each positioning mode is a conventional positioning mode, it controls the positioning module with a key at each delay cycle to obtain real-time absolute position information, and each game control device collects the corresponding game operation key state signal and real-time absolute position information and transmits them to the game host in a timely manner.

[0036] In an optional embodiment, when the game host 1 and each game control device 2 communicate, the game positioning of the game control device 2 can be performed by the second UWB module 211 or the key control positioning module 24. The real-time position information (real-time relative position information and / or real-time absolute position information) collected by the game control device 2 is mapped to the game character screen of the game host. Specifically, in this invention, it is possible to switch between the positioning modes of the second UWB module 211 and the key control positioning module 24. The second UWB module 211 calculates the real real-time distance of the game control device 2 itself from the relative position of each game control device 2 by calculating the difference between the communication time between each game control device 2 and the communication time between the game control device 2 and the game host 1, transmits that distance to the game host 1 for processing, and can display the processing result on the game display device. For highly realistic games, the realism of the game can be enhanced and the player's game experience can be improved. In games where real-world distance is not required, the key control positioning module 24 can acquire the real-time position between each game control device 2, transmit this real-time position to the game host 1 for processing, and display the processing results on the game display device. This allows the real-time position to be relatively close to the actual position, significantly improving the player's gaming experience and saving memory consumption associated with calculating real-time distance.

[0037] In an optional embodiment, the game control device further includes a device control module 26 and a game key 27, the device control module 26 being connected to the second ultra-low latency communication module 21, a signal acquisition module 22, a buffer 23, a key control positioning module 24, a switching module 25, and the game key 27. Each of the game control devices performs ultra-low latency game operations through the device control module 26. The game host 1 receives real-time relative position information of each of the game control devices 2 and matches the respective related spatial positions of the game characters corresponding to each of the game control devices 2 in real time based on the real-time relative position information. The game host 1 also receives key state signals from each of the game control devices 2 and matches the respective related game operations of the game characters corresponding to each of the game control devices 2 in real time according to the key state signals.

[0038] In an optional embodiment, each device control module acquires the current game type of the game host, each device control module acquires a switching signal for the corresponding game control device, and switches the positioning mode of the game control device corresponding to each device control module according to the acquired switching signal. The game host receives real-time relative position information or real-time absolute position information for each game control device, matches the respective associated spatial positions of the game characters corresponding to each game control device in real time based on the real-time relative position information or real-time absolute position information, and the game host receives key state signals from each game control device, and matches the respective associated game actions of the game characters corresponding to each game control device in real time according to the key state signals.

[0039] Example 3 As shown in Figures 1 to 5, the present invention provides an embodiment of an ultra-low latency game system including a game host 1 and a plurality of game control devices 2 that are communicably connected to the game host 1.

[0040] Specifically, as shown in Figure 6, the ultra-low latency steps between each game control device 2 and the game host 1 include the following steps: S100: Acquires switching information and switches each positioning mode to either UWB positioning mode or conventional positioning mode based on the switching information. S200: Each key status signal and position information in the current positioning mode are scanned and collected at each scan cycle. S300: Within the transmission cycle, the collected key status signals and location information are transmitted to the game host 1.

[0041] In an optional embodiment, the game host receives key state signals and position information transmitted from the game control device at intervals of the delay period. The present invention achieves ultra-low latency for game data transmission using a device control module, significantly reducing the delay time between the game control device and the game host to 0.2ms to 1.2ms, which is a significant reduction compared to the 16ms of the conventional technology. Furthermore, to further avoid concentrated transmission by the game control device and transmission delays caused by signal interference during transmission, the present invention starts data transmission within the transmission period (i.e., 200μs), thereby ensuring sufficient time and transmission balance for the transmission process and effectively avoiding time delays that occur during the transmission process.

[0042] In an optional embodiment, step S200 includes the following steps: When each game control device determines that its positioning mode is UWB positioning mode, it transmits a positioning data signal to the second UWB module of another game control device via its second UWB module at each delay period, records the transmission time, waits for the other game control device to transmit a feedback signal of the received positioning data signal, records the reception time, calculates the real-time relative position with respect to each of the other game control devices based on the time difference between the reception time and the transmission time, and the transmission speed of the data transmission, and each game control device collects the corresponding game operation key state signal and real-time relative position information by scanning and transmits it to the game host in a timely manner.

[0043] When each game control device determines that its positioning mode is a conventional positioning mode, it controls the positioning module with its key at each delay cycle to obtain its real-time position. Each game control device then collects the corresponding game operation key state signal and real-time absolute position information by scanning and transmits it to the game host in a timely manner.

[0044] In an optional embodiment, the first UWB module 111 is wirelessly connected to the second UWB modules 211 of multiple game control devices 2, thereby enabling accurate acquisition of the precise distance between the multiple game control devices 2 and the game host 1. This allows for a more detailed multidimensional spatial positional distance of the game control devices 2 to be realistically reproduced, making the real-time position of the game character corresponding to the game control devices 2 more realistic and further improving the gaming experience.

[0045] In an optional embodiment, the game control device 2 further includes a power supply module 28 connected to the device control module 26, specifically, the power supply module 28 acquires a 5V voltage which is then reduced to 3.3V by the power supply module 28. Furthermore, the second USB module 212 and the device control module communicate using the DP / DM protocol, and the device control module and the second UWB module 211 communicate using the UART serial port protocol.

[0046] In an optional embodiment, the game host 1 further includes a host control module 13 to which either the first ultra-low latency communication module 11 or the USB dongle receiver 12 is connected.

[0047] In an optional embodiment, step S100 includes the following steps: The device control module 26 of each game control device 2 acquires the current game type from the game host 1 and automatically switches the positioning mode of the game control device 2 corresponding to the device control module 26 according to the current game type. The game type may be set to 1 for real-world games, including VR / 3D games and virtual-world games such as arcade games, and to 0 for virtual-world games.

[0048] In another optional embodiment, step S100 includes the following steps: Each device control module 26 acquires a switching signal from the corresponding game control device 2, and switches the positioning mode of the game control device 2 corresponding to the device control module 26 according to the acquired switching signal.

[0049] In this embodiment, the game host 1 receives real-time relative position information or real-time absolute position information from each game control device 2, and matches the respective associated spatial positions of the game characters corresponding to each game control device 2 in real time based on the real-time relative position information or real-time absolute position information. The game host 1 receives key state signals from each game control device 2, and matches the respective associated game actions of the game characters corresponding to each game control device 2 in real time according to the key state signals, and the spatial positions and game actions set for each character are all displayed by the display device.

[0050] As described above, the present invention employs an automatic or key-controlled method to enable switching between multiple positioning modes in a game system, thereby improving the realism of the game scene. On the other hand, by efficiently controlling the transmission of positioning data and key state signals with ultra-low latency using a device control module, the latency from the game control device to the game host is reduced to 0.2ms to 1.2ms, significantly improving transmission efficiency compared to the conventional technology's 16ms, and enhancing the player's game operation experience.
