Embodiment Construction
[0039] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] like figure 1 , figure 2 Shown, the present invention is based on the streaming media wireless adaptive transmission method of TCP / UDP mixed protocol, comprises the steps:
[0041] (1) The sender uses the reliable TCP protocol to establish a two-way level 0 channel with the receiver, and uses the unreliable UDP protocol to establish a one-way level 1 channel with the receiver, such as image 3 shown.
[0042] In this embodiment, the level 0 channel transmits key frame data from the sending end to the receiving end, and the control information packet is transmitted from the receiving end to the sending end, which is reliable transmission; the level 1 channel transmits non-key frame data, which is Unreliable transmission.
[0043] The control info...
