    Abstract: This application provides a data reading method for a retrieval task and a retrieval apparatus. The method includes receiving a first retrieval task request, where the first retrieval task request corresponds to a first retrieval start address and a first retrieval end address in a target data area, and reading data for a first retrieval task starting from the first retrieval start address. The method includes receiving a second retrieval task request in a process of reading data for the first retrieval task. The method further includes obtaining an address of data to be read for the first retrieval task after receiving the second retrieval task request, and determining a second retrieval start address of a second retrieval task in the target data area based on the address of the data to be read. The method further includes reading data for the second retrieval task starting from the second retrieval start address.

    Abstract: This application discloses a method and an apparatus for sending a virtual reality image, to improve accuracy of an image compression ratio determined when a virtual reality image is sent. The method includes: receiving, by a virtual reality host, first motion information sent by a virtual reality device, where the first motion information is used to indicate a current motion status of the virtual reality device; determining, by the virtual reality host, a first image compression ratio based on the motion information; compressing, by the virtual reality host, a to-be-sent virtual reality image based on the first image compression ratio; and sending, by the virtual reality host, the compressed virtual reality image to the virtual reality device.
