Problems solved by technology

[0006] In the prior art, the lecturer terminal and each student terminal are connected through a matrix switcher. In order to realize bidirectional transmission between the lecturer terminal and each student terminal, both the lecturer terminal and each student terminal need to be connected to the matrix switcher through two transmission lines. , one transmission line connects the output end of the lecturer end or each student end to the input end of the matrix switcher, and the other transmission line connects the input end end of the lecturer end or each student end to the output end of the matrix switcher. Maintenance, and the switching of media signals is complicated, and the experience of human-computer interaction is not good

Embodiment 2

[0075] A control method is applied to the controller of the group discussion training system described in the first embodiment.

[0076] like figure 2 As shown, the control method includes the following steps:

[0077] Step 1: display an interactive interface on the screen, the interactive interface includes a control mode list, a synchronization mode list, a local side list, a student side list and a layouter list.

[0078] In this step 1, the control mode list, the synchronization mode list, the local terminal list, the student terminal list and the layout device list are all located on the edge of the screen. In this embodiment, the control mode list and the synchronization mode list on the lower edge of the screen, the student list is on the left edge of the screen, the local list is on the right edge of the screen, the layouter list is on the on the upper edge.

[0079] The control mode list includes various control modes that can be selected by the lecturer, the sync...

Embodiment 3

[0101] An IP device with a bidirectional codec function is used as a master IP device or a slave IP device in the group discussion training system described in Embodiment 1.

[0102] like image 3 As shown, the IP devices include:

[0103] A local receiving module, configured to receive the first media signal from a local source device (first source device or second source device);

[0104] An IP receiving module, configured to receive a second IP media stream from an IP network (Ethernet switch);

[0105] A video decoding module, configured to decode the second IP media stream received by the IP receiving module into a second media signal;

[0106] A local sending module, configured to send the first media signal received by the local receiving module and / or the second media signal decoded by the video decoding module to a local display device (the first display device or the second display device) to display;

[0107] A video encoding module, configured to encode the fir...

Abstract

The invention discloses an IP device with bidirectional encoding and decoding functions. The device comprises a local receiving module, an IP receiving module, a video decoding module, a local sendingmodule, a video encoding module, an IP sending module and a main control module, and the main control module is used for controlling the local receiving module, the IP receiving module, the video decoding module, the local sending module, the video encoding module and the IP sending module. The IP device realizes bidirectional encoding and decoding functions based on an IP network, and can reducethe number of wiring and the number of device ports.

Description

technical field [0001] The invention relates to IP audio and video transmission technology, which can be used in the education and training industry, especially the teaching scene requiring group discussion. Background technique [0002] The functional requirements of the group discussion training system are mainly as follows: [0003] 1. Each student terminal is equipped with a demo switcher, which supports the input of multiple media signals, and supports the local output of one media signal. For the convenience of comparison and discussion, each demo switcher can support multi-screen function, each The student terminal can transmit its local media signal to the lecturer terminal for display; [0004] 2. The lecturer end is equipped with a presentation switcher, which supports multiple media signal inputs and local output of at least 2 media signals, one can be connected to a large-screen projection, and the other can be connected to a local monitor output, which is conve...
