How to implement a conference call

Abstract

The invention discloses a method for realizing a teleconference, which is invented to solve the problems of less output information, too complicated control and realization, and high cost. The present invention comprises the following steps: when the input synchronous signal is valid, the input processing module flips and converts the input data and sends them to the memory and the conference accumulator respectively for storage; accumulates the voice data and the value of the conference accumulator; When the frame header signal is valid, store the accumulated value into the conference register, and clear the accumulator at the same time; trigger the clock signal edge to fetch the voice data from the memory, and obtain the output calculation value of the current time slot in the conference superposition process ; The system stores the output calculation value into the output processing module, and the output processing module converts and flips the output calculation value before outputting it. In this way, it not only occupies less resources, but also is convenient to control, and the output information is abundant, and the cost is relatively low.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for implementing a teleconference. Background technique [0002] The principle of teleconference is to make every participant of the conference hear the voice of other participants. The specific implementation is to process the voice data of the conference participants, and then send the processed voice to the conference participants. There are many practical applications of conference phones, but their implementation methods have some defects. [0003] The patents CN99105937 and CN03128420 discriminate the voice of conference participants, store the maximum voice value and the second largest value separately, and then output the maximum value to all conference participants, and the second largest value is sent to the participant with the largest voice value. In this way, the conference phone will essentially only have one person speaking, and the amount of out...

Problems solved by technology

Although this implementation method has avoided the shortcoming of the patent CN99105937 outputting less information, the control and implementation are too complicated and will take up a large amount of software and hardware resources

[0005] At present, there is also a 64-channel conference phone chip, which can complete 64-channel call processing. In practical applications, the number of conference participants may not be large, so using a 64-channel voice chip on a single board increases the cost.

Moreover, if participants need to choose to participate in multiple conference calls, multiple chips must be used in the chip implementation method, and peripheral control must be added, which not only takes up board space but also increases costs.
