Communication for coordination, is the network architecture that dynamically can constantly extend, to any two equipment using wireless Mesh netword
It can keep wireless interconnected.Since Mesh network can communicate with other network cooperatings, selected in multiple playback equipments
Select one of them to be connected with WIFI or cable network, you can realize that multiple playback equipments play multimedia function at the same time, increase
Strong broadcasting is multimedia intelligent and convenience.
In the present embodiment, when download apparatus receives the playing request of destination multimedia, examined with prefixed time interval
Survey the network transmission quality of download apparatus and one or more playback equipments；Download apparatus is according to the network transmission quality, really
The play quality attribute for the destination multimedia that fixed one or more playback equipment can play；Download apparatus is loaded with server
The multimedia code stream of the foot play quality attribute, and multimedia code stream is sent to one or more of playback equipments and is carried out
Play.Pass through broadcasting for the destination multimedia that determines to play according to the network transmission quality of download apparatus and each playback equipment
Put qualitative attribute so that each playback equipment can play identical destination multimedia at the same time, improve result of broadcast, and then improve
The intelligent and convenience that multimedia is downloaded.
One of ordinary skill in the art will appreciate that realize all or part of flow in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in a computer read/write memory medium
In, the program is upon execution, it may include such as the flow of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
Dish, CD, read-only memory (Read-Only Memory, ROM) or random access memory (Random Access
Memory, RAM) etc..
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
Enclose, therefore equivalent variations made according to the claims of the present invention, it is still within the scope of the present invention.
