Embodiment 1
[0086] An embodiment of the present invention provides a method for acquiring a video code stream, such as figure 1 As shown, the method includes:
[0087] 101. The terminal acquires the minimum code rate corresponding to its own parameters.
[0088] For this embodiment of the present invention, the parameter of the terminal may be the physical size of the terminal. In the embodiment of the present invention, the terminal can obtain the parameters of the terminal through the protocol, and can also obtain the parameters of the terminal by calling a function, which is not limited in the embodiment of the present invention.
[0089] For example, if the terminal is a computer, the terminal can obtain and save the information stored in the DDC (Display Data Channel, display data channel) chip through the graphics card inside the computer according to the DDC / CI (Display Data Channel Command Interface, display data channel command interface) protocol. parameters of the terminal. ...
Embodiment 2
[0113] An embodiment of the present invention provides a method for acquiring a video code stream, such as Figure 4 As shown, the method includes:
[0114] 401. The terminal obtains the physical size of the terminal.
[0115] For the embodiment of the present invention, the terminal can obtain the physical size of the terminal through a protocol, and can also obtain the physical size of the terminal by calling a function, which is not limited in the embodiment of the present invention.
[0116] For example, if the terminal is a computer, the terminal can obtain and save the information stored in the DDC (Display Data Channel, display data channel) chip through the graphics card inside the computer according to the DDC / CI (Display Data Channel Command Interface, display data channel command interface) protocol. physical dimensions of the terminal. If the terminal is a mobile phone, the terminal can call the DisplayMetric class function in the system program package through a...
Embodiment 3
[0181] 701. The server receives a video code stream acquisition request sent by a terminal.
[0182] Wherein, the video code stream acquisition request carries an identifier corresponding to the video data that the terminal needs to acquire.
[0183] 702. The server sends the media index description MPD to the terminal.
[0184] Wherein, the MPD includes the corresponding relationship between the minimum code rate corresponding to each physical size and each video code stream corresponding to the video data. In the embodiment of the present invention, each video code stream is obtained by encoding the original video data according to each code rate by the server, and each physical size in the MPD has a corresponding minimum code rate and video code stream.
[0185] For the embodiment of the present invention, the server sends the media index description MPD to the terminal, so that the terminal obtains the video code stream according to the MPD and the minimum bit rate.
