Description
The present application is a divisional application of chinese patent application 201510079805.4 entitled "a method, an apparatus and a system for streaming media data transmission" filed on 13.02/2015.
Technical Field
The present invention relates to the field of streaming media transmission, and in particular, to a method, an apparatus, and a system for transmitting streaming media data.
Background
With the development of computer technology and wireless communication technology, digital multimedia enters an industrialization stage, and various multimedia application platforms gradually mature in the industrialization process. WLAN (Wireless Local Area network), Bluetooth (Bluetooth) and 3G (3 rd-generation mobile communication technology) technologies have been able to provide basic bandwidth to meet the requirements of various multimedia and real-time video transmission applications; meanwhile, the computing power of the embedded system makes the realization of real-time multimedia information processing on mobile equipment become a reality gradually. For home and abroad, the real-time streaming media transmission is mainly applied to the fields of video conferences, multi-screen sharing and the like. Compared with other multimedia services, streaming media data transmission has strict requirements on the aspects of instantaneity, network bandwidth, fault tolerance, media synchronization, playing smoothness and the like.
On one hand, the streaming media has high requirements on available bandwidth of the network, and the current Internet (Internet) does not reserve enough bandwidth for the streaming media; moreover, the existing router generally adopts a storage forwarding and queue passive discarding mode, and when the network bandwidth fluctuates, the mode easily causes a large delay or a discarding phenomenon of the streaming media data packet, thereby causing a great influence on the transmission and playing quality of the streaming media.
On the other hand, streaming media has significantly higher latency requirements than general data. If the delay of real-time voice cannot be higher than 250ms, and the delay of real-time video cannot be larger than 1s, but the Internet does not provide a delay guarantee for real-time streaming media data, the streaming media data still needs to go through the storage, queuing and forwarding processes of the router as common data, when the network is congested, the queue delay of only the streaming media data on the router often exceeds the minimum delay required by the streaming media, and the media data packet delayed to reach the receiving end causes poor playing effects such as pause, jitter and the like when being played.
Moreover, the heterogeneity of the network and the heterogeneity of the user put higher demands on the transmission of the streaming media. In the Internet, the distribution of network resources (e.g., link bandwidth, storage capacity, processing power, congestion control policies, etc.) is non-uniform. The heterogeneity of the network means that two or more wireless communication systems use different access technologies, or use the same wireless access technology but belong to different wireless operators. By utilizing various existing wireless communication systems and by means of intersystem fusion, making use of the advantages and the disadvantages of multiple systems is an effective means for meeting the requirements of future mobile communication services, and the advantages of the systems can be comprehensively exerted. Because various existing wireless access systems are overlapped in a plurality of areas, the wireless access systems of different types which are overlapped with each other can be intelligently combined together, and a plurality of different types of networks jointly provide wireless access to users anytime and anywhere by utilizing an intelligent access means of a multimode terminal, thereby forming a heterogeneous network. Based on heterogeneous network Access mode, (e.g. ethernet, ADSL (Asymmetric Digital subscriber line), Wi-Fi (wireless network), WiMax (Worldwide Interoperability for microwave Access), GPRS (General Packet Radio Service), 3G network, etc.), heterogeneous terminal device, (e.g. PC, notebook, PDA (Personal Digital assistant), or mobile phone, etc.), and heterogeneous user requirements (e.g. requiring audio priority, video priority, or speed priority, etc.), the transmission requirements and audio/video quality requirements of the terminal user for the streaming media are different, thereby aggravating delay during streaming media data transmission, causing pause of streaming media, even no playing, etc.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention can be applied to application scenes of transmitting various types of streaming media data through an Internet network, and the embodiment of the invention can be particularly suitable for application scenes of multi-channel real-time streaming media transmission based on wireless spectrum sensing. In the embodiment of the present invention, the sending end of the streaming media data may be a server or other network devices, and the receiving end of the streaming media data may be various terminals; generally, a transmitting end may be a network device capable of supporting multi-channel communication, and a receiving end may be a terminal device capable of supporting multi-channel communication, or may also be a terminal device capable of supporting only single-channel communication; the method comprises the steps that a sending end and a terminal can establish a link on a communication link through a router, the router can support multichannel communication capacity or not, and when the router does not support the multichannel communication capacity, the sending end and the receiving end can establish the link on the communication link in various end-to-end direct connection modes.
The embodiment of the invention aims at the problem that the wireless network environment in the prior art is easily interfered by the outside world, such as: because the wireless network has the problems of low bit rate, high packet loss rate, strong interference and the like, compared with wired real-time streaming media transmission, the wireless transmission channel environment is much worse, and the receiving bit error rate of the data packet is higher by several orders of magnitude than that of the wired network. The compressed video stream is very sensitive to bit errors, and even if the bit error rate of a received data packet is very low, the decoded image quality is also seriously affected. The reason is that the compression coding removes most of redundant information on the spatial domain and the time domain contained in the original image, and even if the coded video stream has only one bit of error, a large part of image data of the spatial domain and the time domain in the decoded image is affected and cannot be normally decoded and displayed. If the frame affected by the error code of the data packet is used as the reference frame of the next predicted frame, the error code of one data packet will be diffused to the next image frame, so that the deterioration condition of the decoded image quality is more serious. The embodiment of the invention provides a two-channel real-time streaming media data transmission technology based on wireless spectrum sensing, which can judge the occupation condition of the current wireless spectrum, select an optimal communication channel to transmit wireless streaming media data according to the judgment result, improve the real-time property of streaming media data transmission, reduce the packet loss quantity during streaming media data transmission, enhance the subjective viewing effect and improve the user experience.
Fig. 1 shows a schematic flowchart of a streaming media data transmission method provided in an embodiment of the present invention, and as shown in fig. 1, the method may include:
step 11: the server sends a request message for acquiring whether the terminal has the capability of supporting the multi-channel communication to the terminal, and determines whether the terminal supports the multi-channel communication according to the feedback message of the terminal.
Step 12: the server determines one or more communication channels for transmitting the streaming media data according to whether the terminal has the capacity of supporting multi-channel communication and/or the quality of a plurality of communication channels, and transmits the streaming media data with the terminal on the determined communication channels.
Optionally, in step 12, if the terminal does not have the capability of supporting multi-channel communication, the server performs streaming media data transmission with the terminal using any one of a plurality of communication channels that the terminal can support; if the terminal has the capability of supporting multi-channel communication, the server transmits streaming media data to the terminal by using a plurality of communication channels or any one of the plurality of communication channels which can be supported by the terminal.
Optionally, in the above step, the quality of the plurality of communication channels includes: the quality of the current communication channel and the quality of a plurality of unoccupied communication channels; the server judges whether the quality of the current communication channel is higher than a first preset threshold value or not, and if so, the current communication channel is used for transmitting streaming media data with the terminal; if not, judging whether a communication channel with the quality of the communication channel larger than that of the current communication channel exists in the plurality of unoccupied channels, if so, taking the communication channel as a communication channel to be switched, sending a change instruction for switching to the communication channel to be switched to the terminal, and after the terminal returns a change confirmation message, carrying out streaming media data transmission with the terminal by using the communication channel to be switched; and if the current communication channel does not exist, the current communication channel is used for transmitting the streaming media data with the terminal.
Optionally, in the above step, the quality of the plurality of communication channels includes: the quality of the current communication channel and the quality of a plurality of unoccupied communication channels; the server takes the currently used communication channel as a main communication channel, takes one or more communication channels in the unoccupied communication channels as auxiliary communication channels, and distributes the streaming media data to the main communication channel and the auxiliary communication channels according to the proportion for transmission; wherein the ratio is related to the network throughput of the primary communication channel and the network throughput of the secondary communication channel.
Optionally, in the above step, when the terminal has the capability of supporting dual-channel communication, the server uses a currently used communication channel as a primary communication channel, uses another communication channel supported by the terminal as a secondary communication channel, and respectively obtains a network throughput T1 of the primary communication channel and a network throughput T2 of the secondary communication channel; the server transmits the streaming media data to the terminal through the primary communication channel in a ratio of T1/(T1+ T2), and transmits the streaming media data to the terminal through the secondary communication channel in a ratio of T2/(T1+ T2).
The following describes embodiments of the present invention in detail.
The embodiment of the invention is mainly divided into two parts: one part is spectrum sensing, and the other part is allocation and transmission of real-time streaming media data. Based on the above concept, fig. 2 shows a schematic structural diagram of a system architecture provided in an embodiment of the present invention, as shown in fig. 2, the system architecture at least includes a transmitting end 21 and a receiving end 22, where the transmitting end 21 may at least include: the system comprises a wireless spectrum sensing module and a real-time streaming media data distribution and transmission module, wherein the wireless spectrum sensing module is used for sensing and analyzing the current wireless spectrum, and the real-time streaming media data distribution and transmission module is used for receiving the real-time streaming media data, distributing the streaming media data according to the sensing and analysis result of the wireless spectrum sensing module, and transmitting the streaming media data to a receiving end through one or more communication channels.
Fig. 3 is a schematic flow chart illustrating a transmission of streaming media data from a transmitting end to a receiving end according to an embodiment of the present invention, where the transmitting end and the receiving end both have the capability of supporting dual-channel communication are taken as an example to describe in the embodiment of the present invention, where one communication channel is a communication channel in a 2.4GHz band, and the other communication channel is a communication channel in a 5GHz band; in practical application, however, the method is not limited to only having the capability of supporting dual-channel communication, and may also have a transmitting end and a receiving end that support multi-channel communication; in the embodiment of the invention, the sending end can be a streaming media server, and the receiving end can be a client or a terminal; as shown in fig. 3, the method may include:
step 31: the streaming server (hereinafter, may be simply referred to as a server) performs initialization.
During specific implementation, the server initializes the dual-band wireless communication module, and can set a communication channel in a 2.4GHz band as a main communication channel and a communication channel in a 5GHz band as an auxiliary communication channel.
Step 32: the server starts monitoring on a preset port number and waits for the client to initiate connection. And after the client requests to connect the server, the server verifies the identity of the client and establishes a streaming media link on the main communication channel.
In specific implementation, a server (usually a streaming media sending end) opens a network interface on a default initial communication channel 0, starts monitoring, and waits for a connection establishment request initiated by a client (usually a streaming media receiving end, that is, a terminal, which may be referred to as a client for convenience of description); the server verifies the identity of the client and establishes a streaming media link on the primary communication channel after the verification is successful.
Step 33: after the link is established, the server sends a request message for acquiring whether the client has the capacity of supporting the dual-channel communication to the client.
In particular implementations, after establishing a connection with a client, a server may request the client for wireless communication capabilities and audiovisual decoding capabilities of the client.
Step 34: the server determines whether the client has the capability of supporting the dual-channel communication according to the response message returned by the client, if so, the step 35 is executed, and if not, the step 36 is executed.
In specific implementation, the client returns a response message carrying the wireless communication capability and the audio and video decoding capability of the client to the client. It should be noted that, when the quality of the current channel is not good, the server may select to execute step 35 or step 36 according to whether the client has the capability of supporting dual-channel communication; if the quality of the current channel is better, the server may keep using the current communication channel for transmission, or may choose to perform step 35 or step 36.
Step 35: when the client side has the capacity of supporting the dual-channel communication, the server uses the main communication channel and the auxiliary communication channel to transmit the streaming media data according to a certain proportion.
In specific implementation, the server initializes its auxiliary communication channel (communication channel in 5Ghz band). At this time, a dual-channel dual-band data connection channel is established between the server and the client, and the server and the client transmit and receive data through the dual-channel dual-band channel. In the process of data sending and receiving, a real-time streaming media data distribution module of the server distributes the data of the real-time streaming media to two different wireless communication channels according to a certain proportion. The real-time streaming media data distribution and transmission module counts the network throughput of each wireless channel in the data transmission process, and if the network throughput of the main channel is represented as T1 and the network throughput of the auxiliary communication channel is represented as T2, the real-time streaming media data distribution and transmission module transmits streaming media data through the main data channel according to the proportion of T1/(T1+ T2) and transmits the streaming media data through the auxiliary data channel according to the proportion of T2/(T1+ T2). In the embodiment of the invention, two frequency bands with larger distance are selected for carrying out the data transmission of the two channels and the two channels, so that the possibility that the two data channels are simultaneously interfered is lower.
It should be noted that, after step 35 is executed, the current streaming media data transmission process is ended, but it does not mean that the streaming media data transmission is performed with the client through the dual communication channel in the subsequent streaming media data transmission process. The server can still sense the wireless spectrum in real time, and performs subsequent streaming media data transmission with the client by using a single communication channel or multiple communication channels according to the sensing result of the wireless spectrum.
Step 36: when the client does not have the capacity of supporting the dual-channel communication, the server determines to use a single communication channel for streaming media data transmission.
In specific implementation, if the client can only support playing of real-time streaming media with a single channel, the server and the client establish a common wireless streaming media transmission channel, that is, a single communication channel is used for streaming media data transmission. When the server and the client establish a common single-channel data connection channel, the server and the receiving end only send and receive data through a single communication channel, however, since the server has at least two communication channels in the embodiment of the present invention, the server can use any one of the main communication channel or the auxiliary communication channel to perform streaming media data transmission with the client.
Step 37: the server determines whether a switch from the primary communication channel to the secondary communication channel is required based on the quality of the primary communication channel and the quality of the secondary communication channel, if not, step 38 is performed, otherwise, step 39 is performed.
During specific implementation, the server determines whether the quality of the current communication channel (i.e., the quality of the main communication channel) is lower than a first preset threshold, and if not, executes step 38; otherwise, judging whether the quality of the auxiliary communication channel is superior to that of the current communication channel (namely the quality of the main communication channel); when the quality of the secondary communication channel is better than the quality of the current communication channel (i.e., the quality of the primary communication channel), step 39 is performed; when the quality of the secondary communication channel is not better than the quality of the current communication channel (i.e., the quality of the primary communication channel), step 38 is performed.
In the embodiment of the present invention, the first preset threshold may specifically be 20%, and a value of the first preset threshold may be adjusted according to an actual application situation.
Step 38: the server still uses the main communication channel to transmit the streaming media data with the client.
It should be noted that, after the step 38 is executed, the current streaming media data transmission process is ended, but it does not mean that the streaming media data transmission is performed with the client through the primary communication channel in the subsequent streaming media data transmission process. The server can still sense the wireless spectrum in real time, and performs subsequent media data transmission with the client by using other communication channels according to the sensing result of the wireless spectrum.
Step 39: and the server sends a change instruction for switching to the auxiliary communication channel to the client, and after the client returns a change confirmation message, the auxiliary communication channel is used for transmitting the streaming media data with the client.
During specific implementation, in the data communication process, a wireless communication spectrum sensing module in a server periodically detects the spectrum use condition in the current wireless communication environment, and when the transmission failure rate of real-time streaming media data is increased, or a large number of data packets are lost, or a network is seriously congested, a data transmission channel is transferred to a communication channel with better wireless communication quality according to the result of statistical calculation of the spectrum sensing module. In this way, in the transmission process, once the current transmission environment condition is perceived to be poor, the server and the client can negotiate to switch to a communication channel with less wireless communication interference or better wireless communication quality according to the result of wireless spectrum perception.
In step 39, if the client does not return a change confirmation message or returns a change failure message, the server still uses the primary communication channel to perform streaming media data transmission with the client.
It should be noted that, after step 39 is executed, the current streaming media data transmission process is ended, but it does not mean that the streaming media data transmission is performed with the client through the secondary communication channel in the subsequent streaming media data transmission process. The server can still sense the wireless spectrum in real time, and performs subsequent media data transmission with the client by using other communication channels according to the sensing result of the wireless spectrum.
According to the technical scheme, the server can send a request message for acquiring whether the terminal has the capacity of supporting multi-channel communication to the terminal, and determine whether the terminal supports multi-channel simultaneous transmission according to the feedback of the terminal, so that a heterogeneous network access mode in the prior art is unified, the server and the terminal access a network by using the same network protocol, and the delay phenomenon of streaming media data transmission caused by the heterogeneity of the network in the prior art is reduced; in addition, the server can also determine one or more communication channels according to whether the terminal has the capability of supporting multi-channel communication and the quality of each communication channel, so that the transmission efficiency can be highest when streaming media transmission is carried out on the determined one or more communication channels, and the congestion phenomenon during streaming media data transmission is reduced.
