The present invention discloses an encrypting communication method and device. The method includes the steps of: (1) generating certain of communication keys at the transmitting terminal and the receiving terminal; (2) the transmitting terminal consults with the receiving terminal of the communication key to confirm a key adopted for communication; (3) the transmitting terminal and the receiving terminal communicate according to the consulted key and go into step (2) to perform key replace when the predetermined condition of replacing communication key is satisfied and then communicate according to the replace communication key. The present invention solves the technology problem of communication safety because of the fixing and unique of the communication key, and the safety and reliability of the communication are improved by the replacing of the key in the communication process by the consulting between the transmitting terminal and the receiving terminal.

The invention discloses a dynamic adaptive code rate selection method based on a MPEG-DASH (MPEG-Dynamic Adaptive Streaming over HTTP) protocol. The dynamic adaptive code rate selection method comprises the steps of: firstly, establishing a HTTP connection between a server and a client; by the client, sending a HTTP Get request to the server, requesting to download a MPD file and storing the MPD file; after the server receives the request of the client, by the server, responding to the client and sending the MPD file, and by the client, downloading the MPD file and parsing the downloaded MPD file; according to an URL address obtained by parsing the MPD file, firstly downloading one part of a slice at the minimum code rate, placing the slice into a cache region, carrying out calculation, statistics and recording on a network bandwidth when the video slice is downloaded, and predicting a network bandwidth when a next video slice is downloaded; and by combining a current residue condition of video slices of the cache region, selecting a code rate for downloading the next video slice until the end. An effect of improving video quality to the greatest extent in the premise of smoothly carrying out playing is achieved, and viewing experience of a user is greatly enhanced.

The invention relates to a light pulse shaper based on a double-array fiber grating, comprises an optical frequency comb source, an optoisolator and an amplitude controller, wherein the output end of the optical frequency comb source is connected with the input end of the optoisolator, the output end of the optoisolator is connected with the input end of the amplitude controller, and the output end of the amplitude controller outputs even function waveform light pulses. A working method of the light pulse shaper based on the double-array fiber grating comprises the following steps of: (1) inputting; (2) controlling amplitudes: splitting light, adjusting phases, and interfering; and (3) outputting. In the invention, the size of light spectrum amplitudes can be continuously accurately changed by only using a fiber stretcher, thereby realizing the dynamic adjustment of the light spectrum amplitudes; simple structure, little loss and easy coupling with other optical devices are achieved; random waveform light pulses of even function waveforms can be output; and shaping bandwidth can be increased by increasing the wavelength interval of adjacent gratings or increasing the number of gratings, thereby enabling the bandwidth of the device to be easy to upgrade.
