In addition, the user interface may also display video controls in other scenes, and exemplary, a secondary page of the homepage application may also display video controls, a primary page of the homepage application displays column classifications including movies, television series columns, and the like, and when the movie classification controls are selected by the user, the user jumps to the secondary page corresponding to the movie classification controls, and the secondary page includes a plurality of video controls corresponding to a movie. As shown in fig. 7 (1), a drama classification control, a movie classification control and an animation classification control are displayed on the primary page, a user can move the focus to the movie classification control and press a confirmation key on the control device, the user interface jumps to a state that a plurality of movie controls are displayed on the secondary page as shown in fig. 7 (2), and the user can move the focus to the movie a control and play a movie corresponding to the movie control a.
In the embodiment of the application, the device identifier corresponds to the display device, and the display device has only one device identifier. The specific form of the device identifier is not limited in this application, and the device identifier may include one or more of a number, letter, and symbol, for example.
The server receives a first request instruction carrying an equipment identifier sent by the display equipment, and searches the playing capability corresponding to the display equipment according to the equipment identifier. The playing capability refers to an encoding protocol supported by the display device, and the encoding protocol can be H.264 or H.265.
In some embodiments, the server itself stores a stored list of device identifiers and playing capabilities, although the device identifiers and playing capabilities may not be stored in a list, and are not limited herein. When the first request instruction is received, the server screens playing capability corresponding to the equipment identifier which is the same as the equipment identifier in the first request instruction from the storage list, wherein the storage list is shown in table 1, the equipment identifier carried by the first request instruction is 001, and the playing capability searched by the server at the moment is H.264.
TABLE 1
Device identification | Play capability |
001 | H.264 |
002 | H.265 |
003 | H.265 |
In other embodiments, the storage list is not stored in the server, but is stored in a storage device connected to the server, where the storage device stores a storage list of device identifiers and playing capabilities, and when the server receives the first request instruction, the server searches the storage device for the playing capability corresponding to the device identifier in the first request instruction.
After finding the playing capability of the display device, the server transmits the playing capability to the display device. And the display equipment acquires the index file through the server according to the playing capability and the video identification corresponding to the video control.
In this embodiment of the present application, the number of index files of each video is determined according to the number of types of playing capabilities, and for example, the playing capabilities of all display devices at present may support h.265 or support h.264, where the number of types of playing capabilities is two, and at this time, each video has two index files, where one index file corresponds to the playing capability supporting h.265 and the other index file corresponds to the playing capability supporting h.264. There are video data addresses at different resolutions in each index file, and illustratively, index file a includes video data address a at 720P resolution under the h.265 encoding protocol and video data address B at 1080P resolution under the h.265 encoding protocol, and index file B includes video data address C at 720P resolution under the h.264 encoding protocol and video data address D at 1080P resolution under the h.264 encoding protocol. In some embodiments, the index file is stored in a server. In other embodiments, the index file is stored in a storage device, and the server searches the corresponding index file from the storage device and issues the index file to the display device.
In some embodiments, the step of obtaining, by the server, the index file according to the playing capability and the video identifier corresponding to the video control includes: searching all index files corresponding to the video according to the video identification, and determining a unique index file through the playing capability.
In some embodiments, the index file corresponds to an index file address, and the index file address corresponds to the video identifier and the playing capability one to one. The server utilizes the video identification and playing capability to search the corresponding index file address instead of directly searching the index file.
In other embodiments, the step of obtaining, by the server, the index file according to the playing capability and the video identifier corresponding to the video control, as shown in fig. 8, includes: a sixth request instruction carrying playing capability and video identification corresponding to the video control is sent to the server, so that the server can send an index file address searched according to the playing capability and the video identification; and sending a seventh request instruction carrying the index file address to the server so that the server can issue the index file corresponding to the index file address.
In some embodiments, the method further comprises: and determining the waiting resolution of the video data to be played. In some embodiments, when an instruction for selecting a video control is received, the resolution to be played of the video data to be played is a preset resolution, and the preset resolution is one of resolutions in the index file.
