example 1

[0055] When the first multimedia input interface is an audio interface, the second multimedia input interface is a video interface for inputting the main video stream, and the output state of the input data stream of the video interface is to output the data stream to the remote device, if the receiving The remote device of the main video stream is connected to the video conferencing system, then it is determined that the output state of the input data stream of the audio interface is to output the data stream to the remote device; otherwise, it is determined that the output state of the input data stream of the audio interface is in Output the data stream locally.

[0056] When the output state of the input data stream of the video interface is converted to not outputting the data stream (that is, the data stream is closed), the output state of the audio interface input data stream is also converted to not outputting the data stream.

example 2

[0058] When the first multimedia input interface is an audio interface, the second multimedia input interface is a video interface for inputting a secondary video stream, and the output state of the input data stream of the video interface is to output the data stream to a remote device, if the receiving The remote device of the secondary video stream is connected to the video conferencing system and the local terminal is in the dual-stream sending state, then it is determined that the output state of the audio interface input data stream is to output the data stream to the remote device; if the secondary video stream is received If the remote device is connected to the video conferencing system and the local terminal is not in the dual-stream sending state, then it is determined that the output state of the input data stream of the audio interface is not to output the data stream; if the remote device receiving the auxiliary video stream is not connected to the TV In the confe...

Abstract

The embodiment of the invention discloses a multimedia data output method and device, which belong to the field of multimedia processing and are used to improve the diversity of ways for a terminal to output multimedia data. In the present invention, when the first multimedia input interface is in the open state, the terminal determines that the first multimedia input interface corresponds to the second multimedia input interface according to the preset correspondence between the multimedia input interfaces; According to the output state of the input data stream of the second multimedia input interface, determine the output state of the input data stream of the first multimedia input interface, and perform output processing on the data stream input by the first multimedia input interface to achieve the output state. By adopting the present invention, the diversity of output modes of multimedia data can be effectively improved.

Description

technical field [0001] The invention relates to the field of multimedia processing, in particular to a method and device for outputting multimedia data. Background technique [0002] With the rapid development of the communication industry, conference TV, as a communication method that has emerged in recent years, has greatly improved the quality of communication between people. At the same time, they can see each other's images. Conference TV has changed the previous conference mode, which not only saves manpower and financial resources, but also improves work efficiency. [0003] With the development of conference TV, there are more and more types of audio input interfaces. The audio input interfaces on conference TV terminals include: wired microphone input interface, line audio signal interface, wireless microphone input interface, Bluetooth audio input interface, high-definition multimedia Interface (HDMI), etc. [0004] In the current conference TV system, the audio...
