Problems solved by technology

[0013] Although 802.11e can be combined with other mechanisms to prevent collisions between data packets, its problem is that the standard gives the power of prioritization to the client
Similarly, this solution cannot coordinate the data sent on the entire WiFi network, so it cannot achieve the optimal scheduling effect

Embodiment Construction

[0040] The media data reorganization method of the present invention can be applied in such as figure 2 Shown under the multimedia delivery system. exist figure 2 Among them, the multimedia transmission system includes multiple user equipments, multiple proxy client modules, multiple access points, a package server, and at least one positioning server, wherein the multiple access points are connected to the package server.

[0041] The difference from the existing real-time voice / video transmission scheme is that the real-time multimedia transmission system of the present invention adds a package server and a proxy client module. Wherein, the package server is used to reassemble the media data package; the proxy client module is used to execute connection, registration and call requests between the source user equipment and the destination user equipment. The proxy client module is in one-to-one correspondence with the user equipment, and can be located inside or outside t...

Abstract

The invention discloses a reorganization method of media data and a group packaging server, the group packaging server comprised a data buffer unit and a data packaging unit is used to recombine the data packages. The data buffer unit is used to queue the received data packages and then send the queued data packages group to the data packaging unit, the data packaging unit is used to recombine the queued data packages group. The reorganization method of media data includes the following steps: Step A, queuing the received data packages; Step B, recombining the data packages that will be sent the same access point. The invention can effectively improve the utilization of bandwidth and downlink efficiency of media data.

Description

technical field [0001] The invention relates to the field of multimedia transmission, in particular to a media data recombination method and a package server. Background technique [0002] WIFI (Wireless Fidelity) is a wireless local area network technology based on 802.11 series. In the WIFI network environment, it supports two channel access methods: distributed access method (DCF) based on CSMA / CA (carrier sense / collision avoidance) and here Centralized control method (PCF) above. [0003] When a wireless device works in an access point-based mode, multiple wireless devices generally use a CSMA / CA channel access method to share a wireless channel. Under this mechanism, the wireless device first obtains the right to use the wireless link through competition, and then uploads the data packet to the access point. The access point caches the data packet sent by the wireless device and obtains the control right of the wireless network. Afterwards, the packet is delivered to ...
