Embodiment Construction

[0026] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0027] The embodiments of the present application are applied in the scene of playing online video. The embodiment of this application provides a communication network architecture in the scene of playing online video, specifically as figure 1As mentioned above, in the communication network, the client is connected to the server as the source station of the video resource through the Internet. During specific implementation, the client receives the video data sent by the server, performs operations such as decoding and buffering on the video data, and then plays the buffered video data through software such as a player in the client. The clients mentioned in this application can be various electronic products that can play videos online, such as computers, mobile phones, and tablet computers.

[0028] The embodiment of the present application also provides a vid...

Abstract

The invention discloses a video bitrate adjusting method and a device, which relate to the technical field of communication. The method and the device provided by the embodiment of the invention can continuously acquire video data of bitrate of a higher level under the condition of guaranteeing smoothness of playing of a video. The method comprises the following steps: if a client side determinesthat buffer time of the video data of a first bitrate in a video buffer zone exceeds buffer lower-limit time of the bitrate, the client side sends a second scheduling request to a server; the server sends video increment data to the client side according to the second scheduling request; the client side updates the video data of the first bitrate in the video buffer zone according to the video increment data, generates the video data of second bitrate and consequently buffers the video data of the second bitrate in the video buffer zone, wherein the video buffer zone of the client side internally comprises the video data of at least two types of bitrate, and the second bitrate is the bitrate one level above the first bitrate. The method and the device are applied to online video playing.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a video code rate adjustment method and device. Background technique [0002] At present, in order to improve the user experience when watching online videos, mainstream online streaming media in the industry have corresponding bit rate adaptive technologies, including Adobe Dynamic Streaming from Adobe, Adaptive Live Streaming from Apple Streaming media technology (Apple Live Streaming), Microsoft's adaptive smooth streaming media technology (Microsoft Smooth Streaming), MPEG's dynamic adaptive streaming media (MPEG-DASH), etc. These bit rate adaptive technologies adjust the bit rate level of the video data to be played by the user according to the detected network performance (packet loss rate, delay, jitter, etc.), so as to provide different users with network performance suitable for their network The video service enables users to watch better video i...
