Problems solved by technology

[0002] Currently known wireless transmission devices for digital information, especially for wireless transmission devices for digital image information, usually use a personal computer to further process and compress image data in a wired or wireless manner, such as Chinese Patent Publication No. 1206847 , the announcement date is February 3, 1999, the camera equipment introduced; this kind of camera equipment can not be used independently without personal computer, and it is not conducive to mobile use, thus causing limitations in use
[0003] Another Chinese Patent Publication No. CN1398112, the announcement date is the technical solution described in the document on February 19, 2003. Its advantages are: it adopts a wireless transmission solution, it can be carried around, and it is easy to operate; but the disadvantage is that it uses traditional WLAN fixed coding and modulation scheme, the maximum data rate is 10Mbps, for the high-speed, real-time image stream, there is still a large space for the improvement of the rate and the optimization of the transmission structure

Embodiment Construction

[0029] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0030] see figure 1 , figure 1 It is a block schematic diagram of the present invention, and the present invention is composed of a first interface unit 11, a second interface unit 13 and a dynamic encoding unit 12 that sequentially connects the first interface unit 11 and the second interface unit 13 . Wherein the first interface unit 11 introduces the code stream sequence of the video image that has been compressed and encoded outside the world by the connection interface 11a, which can be an asynchronous serial high-speed interface (such as USB, IEEE1394 serial interface); wherein the dynamic encoding unit 12 The functions include: analyzing, detecting and identifying the code stream sequence output by the first interface unit 11 through the connection line 122a, so as to determine which encoding type of the currently input video image belon...

Abstract

This invention relates to an inserted wireless encoding device of a dynamic access encode strategy containing a first interface unit introducing outside compressed and encoded video image code stream sequences and a second interface unit transmitting the code stream sequences in the carrier way of electromagnetic wave, a dynamic encoding unit connecting the two interface units in wire and providing a compatibility on the inserted wireless transmission platform to different forms of digital image code streams to finish the dynamic encoding of multiple code stream velocities within the limited wireless resource environment.

Description

technical field [0001] The invention relates to an embedded digital code stream wireless transmission platform, in particular to an embedded coding device for wirelessly transmitting various compressed and encoded digital code stream information by adopting a dynamic coding strategy. Background technique [0002] Currently known wireless transmission devices for digital information, especially for wireless transmission devices for digital image information, usually use a personal computer to further process and compress image data in a wired or wireless manner, such as Chinese Patent Publication No. 1206847 , the announcement date is February 3, 1999, the camera equipment introduced; this type of camera equipment can not be separated from the personal computer and used independently, and is also not conducive to mobile use, thus causing limitations in use. [0003] Another Chinese Patent Publication No. CN1398112, the announcement date is the technical solution described in ...
