Embodiment Construction

[0026] The method for implementing conference call control by utilizing the DSP conference processing chip of the present invention will be specifically described below with reference to the accompanying drawings, taking the DSP chip TMS320VC5402 of TI Company as an example. It can be understood that the present invention is not limited to this chip, and any processor or programmable device can be selected when applying the method provided by the present invention.

[0027] refer to figure 1 , the DSP conference processing chip (TMS320VC5402) used in the present invention includes a host interface, namely figure 1 in the HPI interface, and two serial ports, namely figure 1 Serial 0 and Serial 1 in the .

[0028] HPI is an 8-bit parallel port. The HPI port is connected to the CPU of the board where the DSP conference processing chip is located. The CPU directly accesses the storage space DARAM inside the DSP through this interface, and supports high-speed data transmission ...

Abstract

The disclosed dialogue control method based on a DSP conference processing chip comprises: initiating the conference way data and broadcast way data; stacking all data of user on conference / broadcastway as the conference / broadcast way data for output; linking conference-way data to the broadcast-way user and user output; stacking all of conference-way user input and broadcast-way user input as the broadcast-way data to output and connect with the k conference-way user outputs. This invention calls API interface on the DSP chip for precise control with low cost and wide applicability, and saves time on secondary development.

Description

technical field [0001] The invention relates to a method for realizing conference call mode control by utilizing a DSP conference chip, and belongs to the technical field of computers. Background technique [0002] The implementation of traditional teleconferencing mainly uses the multi-party call function of the internal exchange (PBX) of the enterprise, but it has great limitations, mainly in the limited number of people participating in the conference, the general exchange cannot exceed 8 parties, and the operation is cumbersome. There are many inconveniences. For a long period of time, when it comes to handling conferences, special conference chips represented by Mitel's MT8924 and ST's M34116 have been given priority. However, with the development of electronic technology, these chips can no longer meet the demands of increasingly complex conference calls. [0003] Based on the limitations of traditional teleconferencing systems, TI's TMS320C54X chip is now used to im...
