Real-time video-oriented pseudo double-stream video coding and transmission method and system

A real-time video-oriented pseudo double-stream video coding and transmission method comprises the following steps: analyzing a real-time video, acquiring a real-time video target code rate when a key frame is generated in the real-time video, and allocating the real-time video target code rate based on a code rate-quantization model to obtain a first code rate path stream and a second code rate path stream; encoding the first code rate path flow and the second code rate path flow according to a preset rule to generate two paths of data messages; and temporarily storing the two paths of data messages in a Pacer sending queue, and sending the data messages to a network according to a preset priority. The method has extremely high compatibility and wide adaptive capacity, does not need to modify the encoder, and has the advantages of high speed and high reliability of a general encoder. According to the method, the long-tail delay and the average delay can be minimized, the low-delay requirements of various real-time and real-time video communication applications are met, and meanwhile, other index performances are guaranteed through more reliable, low-delay and low-packet-loss transmission.

High-precision positioning Bluetooth watch based on double-frequency GPS 8

The utility model provides a high-precision positioning Bluetooth watch based on a dual-frequency GPS 8, and the watch comprises a housing, the interior of the housing is fixedly provided with a holder, the interior of the holder is movably connected with a lithium battery in a clamping manner, one side of the lithium battery is provided with a control mainboard, the control mainboard is connected with the holder in a clamping manner, and the bottom of the control mainboard is provided with a wireless charging module. An electric control button is arranged in the middle of the upper surface of the control mainboard, and a GPS module is welded to one side of the control mainboard. Through the arrangement of the Bluetooth transceiver, the control chip and the GPS module, when the watch carries out positioning operation, information transmission with multiple satellites can be formed at the same time, and the L1 + L5 wave band of each satellite is received; therefore, the multi-signal information overlapping positioning operation is completed, and the problems that in the prior art, GPS single-frequency positioning is adopted mostly, so that positioning updating is very easy to occur slowly on a crowded road section or a tunnel mountain road with poor signals, judgment of a user on the position of the user is affected, and then the user misses an intersection are solved.
