VIDEO PLAYING METHOD, DEVICE AND SYSTEM
FIG6B is a schematic structural diagram of a device according to an embodiment of this application 
When the processing unit 602 is a processor, the communications unit 603 is a communications interface, and the storage unit 601 is a memory, the device in this embodiment of this application may be a device shown in FIG6B. Referring to FIG6B, the device 610 includes a processor 612, a communications interface 613, and a memory 611. Optionally, the device 610 may further include a bus 614. The communications interface 613, the processor 612, and the memory 611 may be connected to each other by using the bus 614. The bus 614 may be a Peripheral Component Interconnect (Peripheral Component Interconnect, PCI for short) bus, an extended industry standard architecture (Extended Industry Standard Architecture, EISA for short) bus, or the like. The bus 614 may be classified into an address bus, a data bus, a control bus, and the like. For ease of representation, only one thick line is used to represent the bus in FIG6B, but this does not mean that there is only one bus or only one type of bus.

['10. A virtual reality VR device, wherein the VR device comprises a communications unit and a processing unit; the communications unit is configured to receive a first-resolution VR video stream of a first viewing angle and a second-resolution VR video stream of a full viewing angle that are sent by a server, wherein the first resolution is greater than the second resolution; the processing unit is configured to play an image of the first viewing angle by using the first-resolution VR video stream of the first viewing angle; the processing unit is further configured to: when the VR device determines that the viewing angle changes, play an image of a current viewing angle by using the first or both of the second-resolution VR video stream of the full viewing angle and the first-resolution VR video stream of the first viewing angle; the communications unit is further configured to send viewing angle information to the server, wherein the viewing angle information carries a parameter for indicating a changed-to second viewing angle; the communications unit is further configured to receive a first-resolution VR video stream of the second viewing angle sent by the server; and the processing unit is further configured to play an image of the second viewing angle by using the first-resolution VR video stream of the second viewing angle.', '15. The VR device according to any one of claims 10 to 14, wherein the VR device further comprises a storage unit; and the storage unit is configured to: store the first-resolution VR video stream of the first viewing angle to a first video buffer, and store the second-resolution VR video stream of the full viewing angle to a second video buffer.']
