Embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Video chat is exactly audio-video frequency media stream on two passages having had built up briefly from the angle of technology
Real time bidirectional transmission is carried out, it is exactly by source IP, source port, purpose IP, destination interface that this passage, which corresponds to operating system aspect,
An and socket determined by transport protocol type this five-tuple.It is full duplex, and its data feedback channel is responsible for local terminal number
According to output, down going channel be responsible for receive remote data.When TV is as the entity to communicate, its down going channel is by distally referring to
Fixed, we are very difficult to change；And for data feedback channel, we can detect and simulate its this client information, so we
Just have an opportunity by IP address spoofing technology, i.e., using raw socket programming to carry out data transmission, and then simulated television is carried out
Communication, the collection of speech data for so being responsible for carrying out by TV originally, coding, transmission can then transfer to completely other-end
It is responsible for completion.
A kind of video call switching method described in present pre-ferred embodiments, as shown in figure 1, the video calling switches
Method comprises the following steps：
Step S100, Intelligent television terminal detects that user establishes the instruction of video calling by Intelligent television terminal.
When it is implemented, intelligent television sets up video calling by Video chat application, mobile terminal also opens video
Talk application software, specifically, the intelligent television and mobile terminal are generally in same LAN.
Step S200, Intelligent television terminal receives the passage handover request order of user, obtains current Intelligent television terminal
Channel information and current medium stream information.
Specifically, the channel information refers to local communication address and the mailing address of receiving terminal of Intelligent television terminal.Tool
During body implementation, user initiates passage handover request by application interface, and television application carries out local data feedback channel information as originally
Ground mailing address, remote communication address, and current transmission medium stream information such as current channel mark（Synchronization
Source Identifier, SSRC）, current RTP（Real-time Transport Protocol, RTP）Number
According to the collection of the sequence number of bag and time stamp etc..
Step S300, the channel information and medium stream information that Intelligent television terminal is switched over needs by broadcast communication
Broadcasted.Specifically, television application passes through broadcast communication, it would be desirable to which the channel information and current media switched over spreads
Defeated information is broadcasted.
Step S400, after the mobile terminal in same LAN receives broadcast, received or refused to cut according to the instruction of user
Change request.
If step S500, mobile terminal receives handover request, the local IP in the broadcast message of Intelligent television terminal is utilized
The IP address of address and receiving terminal is forged to the IP address of mobile terminal, mobile terminal simulated television sendaisle information and
Medium stream information is to receiving terminal.
When it is implemented, after the mobile phone in same LAN receives broadcast, need to select to receive according to user or refusal is cut
Request is changed, if receiving handover request, parsing broadcast message, and IP heads, UDP head essential informations are constructed according to TV IP address,
Raw socket is established according to far-end address, while starts the collection of audio, coding, and the media information in broadcast message
Data are packaged and sent to terminal..
The step S500 specifically includes following steps：
If step S501, mobile terminal receives handover request, the broadcast message of Intelligent television terminal is parsed；
Step S502, mobile terminal constructs IP address and UDP head essential informations according to the IP address of Intelligent television terminal；
Step S503, mobile terminal establishes raw socket according to receiving terminal address, while starts audio frequency of mobile terminal
Collection and coding；
Data are formed packet by medium stream information step S504, in broadcast message, simulate Intelligent television terminal
Packet is sent to receiving terminal.
Specifically, the raw socket is by source IP address, source port, purpose IP address, destination interface and transmission association
View composition.
Present invention also offers a kind of system architecture schematic diagram of the first Application Example of video call switching method, such as
Shown in Fig. 2, user Alice and user Bob carries out Video chat in the present embodiment, and the system includes intelligent television, auxiliary intelligence
Can mobile phone, router, Sip servers, receiving terminal.Specifically operation principle is：
Intelligent television is set up by Sip servers where intelligent television and router and Bob used in Alice first
Receiving terminal between establish session connection；
When intelligent television is not communicated using auxiliary smart mobile phone, it is logical that intelligent television can use voice data to send
Road, audio-frequency information is sent to router, router and uses media flow transmission（P2P）Or transmission of multimedia streams（proxy）Form
Audio-frequency information is sent to the receiving terminal to where Bob.
When sending voice data using smart mobile phone auxiliary, the intelligent television used in Alice passes through broadcast and auxiliary intelligence
Can mobile phone establish control link, auxiliary smart mobile phone is responsible for the collection of voice data, coding, IP camouflages, data packing and sent,
By the voice data sendaisle of mobile phone, voice data is sent to router, router and uses media flow transmission（P2P）Or
Transmission of multimedia streams（proxy）Form sends audio-frequency information the receiving terminal to where Bob, completes the hair of a voice data
Send.
