摘要： Example video data processing methods and apparatus are disclosed. One example method includes obtaining viewport information by a server. The server obtains spatial object information based on the viewport information, where the spatial object information is used to describe a specified spatial object in panoramic space. The server obtains a first bitstream that is obtained by encoding image data in the specified spatial object. The server obtains a second bitstream that is obtained by encoding image data in the panoramic space. The server transmits the first bitstream and the second bitstream to a client.

摘要： A channel switching processing method includes receiving, by a switching server, a channel switching request from a receiving end. When the switching server determines that current switching resource information does not meet a switching condition according to the channel switching request, the switching server performs an exception handling procedure and sends channel switching instruction information to the receiving end. The channel switching instruction information is configured to instruct the receiving end to perform a channel switching operation corresponding to the channel switching instruction information.
