Further, when the storage module is used for delayed storage, the initial delayed storage time tc is set in the management unit, and the initial delayed storage time is adjusted according to the maximum effective transmission speed and the predicted voice transmission speed, the smaller the maximum effective transmission speed is, the slower the same data transmission process is, so the adjusted delayed storage time is longer, the larger the same predicted voice transmission speed is, the slower the same data transmission process is, so the adjusted delayed storage time is longer, and the integrity of the converted voice data is further ensured.
Further, when the predicted voice transmission speed does not exceed the maximum effective transmission speed, the management unit transmits the image data through the idle network, judges whether the idle network can transmit the image data by setting the minimum transmission speed of the image data and comparing the calculated idle transmission speed, transmits the image data at the minimum transmission speed when the idle transmission speed reaches the minimum transmission speed standard, reserves a better network environment for voice data transmission while transmitting the image data, and ensures normal transmission of the voice data.
Particularly, when the conversion unit transmits conference data to a remote conference terminal, the data information to be transmitted is known, and the real-time transmission delay state of the network is also known, so that the occupation ratio of the image data and the voice data in the conference data is judged, a first preset ratio and a second preset ratio are set, when the real-time image-voice ratio is lower than the first preset ratio, the occupation ratio of the image data in the conference data is smaller, the importance degree of the judged image data changed is lower than that of the voice data, so that the voice data is transmitted separately to ensure the conference, the image data is stored, when the real-time image-voice ratio is higher than the second preset ratio, the conference data is less, the image data is more, so that the importance degree of the image data is judged to be higher than that of the voice data, and the image data is transmitted, the voice data are stored, the data volume with the same transmission time is reduced, the priority transmission of important data is guaranteed, and the digital conference is prevented from being jammed and not influenced.
Further, when the management unit determines that the real-time image-to-voice ratio is between the first preset ratio and the second preset ratio, the management unit indicates that the management unit cannot determine the importance of the voice data and the image data through the data volume, so that the operation of preferential transmission cannot be performed, and therefore, the processing of delay conversion storage is performed on the whole of the image data and the voice data, namely the conference data, the set delay conversion duration is corrected according to the real-time network delay state, the delay conversion duration is adjusted according to the real-time delay condition, and the fact that when the real-time delay is larger, the complete conference data can be stored is guaranteed.
Further, the storage state of the storage module is detected by using the management unit, the countdown of the time length of delayed conversion is carried out by starting to store, when data are stored, the data transmission which is being transmitted is completed, the transmission process is guaranteed to be only aiming at the data information stored in the storage module, the time length of delayed conversion is set, the transmission channel is completely emptied, the integrity of the stored data transmission is guaranteed, meanwhile, the data in the whole section are stored for concentrated transmission in different times, the digital conference flow is further guaranteed to be carried out, the data loss is avoided, and the voice data and the image data are prevented from being blocked.
