Abstract
The method consists of the sending and the receiving parts. (1) The sending end divides the original audio sample data into several equal-size process units. The flow of the sending end includes: dividing original audio sample data into units, data compressing against each unit with the Ogg algorithm, encrypting data and network-packaging the info data. (2) The receiving end finds out the buffer point of memory from the received data info, reads out and de-encrypts the data, decompressing them with the Ogg algorithm to obtain the original audio sample data and sends them to the audio card viabuffers and interface.
Description
Technical field
The present invention relates to a kind of electronic information transmission technology, particularly a kind of audio signal is safety quick transmission and the instant method of playing in network.
Technical background
Along with popularizing of the Internet and developing rapidly of self, the online amusement of network, (as online video display or song), become a kind of entertainment way that numerous netizens like, confidentiality that network provides then becomes the decisive factor of network service quality so, also be quality, the real-time of online audio frequency, video data under this overall situation, the instantaneity of broadcast, and the outstanding and crucial problem of the branch of data.
Existing transmission method is:
1, stream media system: stream media system has the communication information agreement of a fixing server (Server) and series usually, and the not enough point of this quadrat method is the flexibility deficiency that seems of the software systems with particular requirement, and small and exquisite inadequately;
2, depend on other Internet protocol is arranged, media play as ftp (style host-host protocol), http (HTML (Hypertext Markup Language)) etc., can directly obtain file from a http-server plays immediately, though have like this with big flexibility, but not enough point is that safe and secret aspect risk is also very big, and transmission speed be because of seeing through the filtration work of a series of agreements, and transmission speed also will be subjected to certain influence.
Summary of the invention
It was both rapid to the objective of the invention is to disclose a kind of transmission information, can safety and the information of guarantee information in transmission course use a kind of flexibly audio signal safety quick transmission and instant method of playing in network again.
For reaching the technical scheme that above-mentioned purpose adopts be:
Audio frequency safety quick transmission in network is formed with reception two parts by sending part with the method for playing immediately, it is characterized in that:
The workflow of A, described transmission part is that original audio sampled data (PCM) is carried out divisional processing unit, and each section carried out data compression with the Ogg algorithm, with AES data is encrypted, and information data is suitable for the networking encapsulation, sends;
The workflow of B, described receiving unit is the receiving network data bag, takes out data decryption, carries out data decompression with the Ogg algorithm, obtains original audio data (PCM), and original sampling data is sent to sound card by buffering area and interface.
Described compression is meant carries out data compression or decompress(ion) with the Ogg algorithm to the analog signal in the transmission to original audio sampled data PCM (Pulse Code Modulation).
Described data encryption and data decryption are meant and adopt AES (Advanced Encrypt Standard high-level data encryption standard) technology that the transmission information in sending and receiving is encrypted or decryption processing.
The invention has the advantages that:
Because this method has adopted advanced Ogg audio compression law technology that transmission information is carried out data compression or decompress(ion), not only cancel the obstruction of expensive and heavy server and the transmission of a series of information communication protocol information, but also accelerated information transmission safety and speed.
Description of drawings
Fig. 1 is a schematic flow sheet of the present invention.Wherein, A is the transmitting terminal flow chart; B is the receiving terminal flow chart.
Embodiment
A kind of transmission information was both rapid, can safety and the information of guarantee information in transmission course use audio frequency safety quick transmission and instant method of playing in network flexibly again.
For reaching the technical scheme that above-mentioned purpose adopts be:
Audio frequency safety quick transmission in network is formed with reception two parts by sending part with the method for playing immediately, it is characterized in that its workflow is:
A, transmit leg:
Several processing units with sizes such as the original audio sampled data (PCM) of required processing are divided into; → carry out the compression of Ogg Audio compression for each processing unit; → to carry out AES (high-level data encryption standard) for the data of compression to encrypt, secret key is specified by system, because this algorithm is for the requirement of length, so do a data length adjustment for incongruent; → to compress with ciphered data with and relevant information carry out networking data encapsulation parcel and handle.
B, recipient:
Receive after the data earlier data are done from agreement stack to the action of giving of internal memory; → from buffering, take out data, these data are processing unit, then first it are carried out the aes algorithm decryption processing of identical secret key; → carry out Ogg Audio compression decompress(ion) for decrypted data, obtain original audio sampled data (PCM); The broadcast of → voice data is sent to sound card by upgrading one section continuous buffering area of logic and interface buffer with data.
Described data compression and decompress(ion) are meant original audio data PCM (Pulse Code Modulation) are carried out data compression or decompress(ion) with the Ogg algorithm to the analog signal in the transmission.
Described data encryption and data decryption are meant and adopt AES (Advanced Encrypt Standard high-level data encryption standard) technology that the transmission information in sending and receiving is encrypted or decryption processing.
Claims (2)
1. one kind makes audio frequency safety quick transmission and instant method of playing in network, it is characterized in that this method forms by sending and receive two parts, and its workflow is:
A, transmit leg:
Several processing units with sizes such as the original audio sampled data (PCM) of required processing are divided into; Carry out the compression of Ogg Audio compression earlier for each processing unit; Carry out AES for the data of compression and encrypt, secret key is specified by system, because this algorithm is for the requirement of length, so do a data length adjustment for incongruent; To compress with ciphered data with and relevant information carry out networking data encapsulation parcel and handle, send;
B, recipient:
Receive after the data earlier data are done from agreement stack to the action of giving of internal memory; Take out data from buffering, these data are processing unit, then earlier to its aes algorithm deciphering of carrying out identical secret key restoring data size also; Carry out Ogg Audio compression decompress(ion) for decrypted data, obtain original audio sampled data (PCM); The broadcast of voice data is sent to sound card by upgrading one section continuous buffering area of logic and interface buffer with data.
2. audio frequency safety quick transmission and the instant method play in network of making according to claim 1, it is characterized in that: described Ogg compression and decompress(ion) are meant with the Ogg algorithm analog signal in the transmission are carried out data compression or decompress(ion).
