Abstract

The invention discloses a media data acquisition method, a media terminal and an online music teaching system, wherein the media terminal comprises a video acquisition unit, a transmission unit and a control unit; the video acquisition unit is suitable for acquiring an image and generating a video frame; the transmission unit is suitable for transmitting the video frame to a media server; and the control unit is suitable for judging whether the transmission unit is jammed or not and generating a first acquisition adjustment parameter according to the code rate of the video frame transmitted by the transmission unit when the transmission unit is jammed.

Description

technical field [0001] The invention relates to the communication field, in particular to a media data collection method, a media terminal and an online music teaching system. Background technique [0002] Currently, in real-time communication solutions such as video conferencing or webcasting, acquisition terminals usually use a constant bit rate (Constant bit rate, CBR) or a dynamic bit rate (Variable Bit Rate, VBR) to acquire and encode multimedia data. For example, the collection terminal uses a fixed bit rate to collect and encode video data. For another example, the collection terminal codes the collected video data in a dynamic bit rate manner. [0003] However, when a specific application implements a communication scheme, the network environment it faces is usually unstable. That is, various situations such as network jitter and network interruption may exist in the network. Most of the existing acquisition terminals face the problem of poor real-time performance...
