Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
In current data transmission (for example, real-time communication data transmission), classification of transmitted data is not performed, so that packet loss, delay, jitter and the like occur under the condition of a weak network or a poor network, and the weak network resistance is poor.
In the present disclosure, video data in real-time communication is taken as an example for explanation. However, it should be understood that the data transmitted in the present disclosure is not limited to video data, but may be any other suitable data. In addition, the terminal for transmitting data in the present disclosure may be a server of a video conference. It should be understood that the terminal in the present disclosure may include, but is not limited to, mobile terminal devices such as a mobile phone, a smart phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, a vehicle-mounted terminal device, a vehicle-mounted display terminal, a vehicle-mounted electronic rearview mirror, etc., and terminal devices such as a digital TV, a desktop computer, etc.
Fig. 1 provides a flow chart of a method of data transmission of an embodiment of the present disclosure. The method of the present disclosure includes step S101, obtaining video data to be transmitted. In some embodiments, for example, in a video conference, the server may obtain video data. It should be understood that the data generated by the video conference described above is merely exemplary, and the disclosure is not limited thereto.
The method of the present disclosure further includes step S102 of determining at least one of the first data channel, the second data channel, and the third data channel. In some embodiments, after the video data to be transmitted is obtained, a data channel for transmitting the data is determined. In some embodiments, the first data channel corresponds to a first type of data in the video data to be transmitted, the second data channel corresponds to a second type of data in the video data to be transmitted, and the third data channel corresponds to a third type of data in the video data to be transmitted. In some embodiments, each frame of the acquired video data stream itself has a type attribute. For example, in some embodiments, the first type of data is key frame data, the second type of data is long term reference frame (LTR) data, and the third type of data is normal reference frame data. In some embodiments, the key frame data refers to I-frame or intra-frame data, the long-term reference frame (LTR) data includes partial P-frames or predicted frames, and the normal reference frames include most P-frames and B-frames (bi-directionally predicted frames). In some embodiments, the I-frame is a key frame and is the most important data, other P-frames and B-frames are substantially referenced to the I-frame, and some P-frames and B-frames are decoded with reference to a long-term reference frame. Therefore, for the transmitted video data, the I frame is the key frame and is the most important data, and the long-term reference frame is the more important data, which can become the basis for the reference of the common reference frame. It should be appreciated that the type attributes of these data are merely exemplary, and other suitable classifications may be made or other suitable types of data may be included.
The method of the present disclosure further includes step S103 of transmitting data corresponding to at least one data channel through at least one data channel. In some embodiments, after determining at least one data channel for data transmission, the corresponding data is transmitted through the at least one data channel without requiring other data channels than the at least one data channel to transmit their corresponding data.
Therefore, by classifying the data, the data with different importance degrees are transmitted through different data channels, so that the priority of the transmitted data can be selected, the data transmission is optimized conveniently, and the security of the key data and the weak network resistance of the data transmission are improved.
By carrying out hierarchical transmission on the data, the determined at least one data channel transmits the corresponding data, which is beneficial to improving the weak network resistance and further improving the quality of service (QoS).
As shown in fig. 2, in some embodiments, after data (e.g., video data) is encoded, the data is transmitted through the first data channel, the second data channel, and the third data channel, and then received by the corresponding first receiving channel, second receiving channel, and third receiving channel of the receiving end, and then the received data is decoded, for example, by a decoder. In some embodiments, the receiving end may be various terminals as described above. In some embodiments, the received data is reordered in time sequence by a buffering module before decoding the data at the receiving end. In some embodiments, the data may include key frame data, long-term reference frame data, and normal reference frame data, and the key frame data, the long-term reference frame data, and the normal reference frame data are transmitted through the first data channel, the second data channel, and the third data channel, respectively. That is, the plurality of data channels correspond to respective multiple types of data.
In some embodiments, the first data channel employs a Transmission Control Protocol (TCP) or a fast reliable network transmission protocol (KCP). The reliability of transmission in the TCP and KCP modes is high, data can not be lost basically, and the defect is that delay can be caused certainly. The first data channel transmits the most important key frame data, and a reliable mode is selected for transmission, so that the safety of the transmitted data is ensured.
In some embodiments, the second data channel employs fast user datagram protocol (QUIC) or Stream Control Transmission Protocol (SCTP). The reliability of the QUIC and SCTP modes is lower than that of the TCP mode, but the transmission speed is relatively higher, and the data transmission efficiency is favorably improved. In addition, in some embodiments, the data to be transmitted further includes Forward Error Correction (FEC) data, and the FEC data may prevent some packet loss situations, for example, the same data packet is sent twice, and after one of the data packets is lost, there is also one data packet, so that a problem caused by the loss of the data packet is avoided. In some embodiments, the FEC data is transmitted over the second data channel.
In some embodiments, the third data channel employs User Datagram Protocol (UDP). Although the reliability of the UDP is poor and data loss may occur, the real-time performance of the UDP is good, and the data transmission efficiency can be improved. In some embodiments, the data to be transmitted further includes a retransmission packet, and when the receiving end feeds back that the data packet is lost, the retransmission packet may exist. In some embodiments, the retransmission packet may be transmitted over the third data channel.
In some embodiments, according to the importance of data, the most important data is reliably transmitted, the less important data is partially reliably transmitted, and the less important data is unreliability transmitted, so that the weak network resistance is improved, and the QoS is improved. A large amount of data are transmitted in a UDP mode, and the data transmission efficiency is improved. In addition, key data are transmitted through the TCP, and data security and weak network resistance are improved.
In some embodiments, the at least one data channel is determined based on a network status. In some embodiments, the network status includes network bandwidth. In some embodiments, for a case where the network bandwidth is greater than or equal to the first threshold, where the network bandwidth is sufficient to transmit all of the data, it is determined that the at least one channel includes the first data channel, the second data channel, and the third data channel. That is, each of the three data channels transmits its corresponding data.
In some embodiments, for a case where the network bandwidth is greater than or equal to the second threshold and less than the first threshold, it is determined that the at least one channel includes the first data channel and the second data channel. In some embodiments, sometimes the state of the network is poor and not enough to transmit all the data in the first data channel, the second data channel and the third data channel, and at this time, the data in the third data channel may be discarded from transmission and only the data in the first data channel and the second data channel may be transmitted. For example, in some embodiments, upon receiving data to be transmitted, the amount of data transmitted over each channel may be detected. In addition, the network bandwidth can be detected in real time. When it is detected that the bandwidth is insufficient to transmit all the data in the first data channel, the second data channel, and the third data channel, the normal frame data in the third data channel may be discarded, and the retransmission packet may not be transmitted, that is, the third data channel is discarded. In this way, under weak networks, transmission of important data (e.g., I-frames and long-term reference frames) is ensured, and the receiving end can still decode and play after receiving the data. By the method, the transmitted data volume is greatly reduced, the safety of important data is ensured, and the weak network resistance is improved.
In some embodiments, the at least one channel is determined to comprise a first data channel for the case where the network bandwidth is less than a second threshold. In some embodiments, when the network status is insufficient to transmit the data in the first data channel and the second data channel, the data in the third data channel and the second data channel may be discarded from transmission, and only the data in the first data channel may be transmitted. That is, when the detected bandwidth and the data in the second data channel cannot be normally transmitted, the third data channel and the second data channel may be discarded, for example, the long-term reference frame and the FEC data in the second data channel are also discarded. In this way, the transmission of the most important data (for example, I frame) is ensured, the transmitted data volume is greatly reduced, the safety of the important data is ensured, and the weak network resistance is improved.
In some embodiments, the first threshold and the second threshold are determined from the video data to be transmitted. In the above embodiment, the attribute of the video data to be transmitted may affect the first threshold and/or the second threshold, and the attribute may include resolution, code rate, frame rate, and/or size, etc. For example, for a 720P video with 24 frames per second, it can be roughly calculated that it needs a bandwidth of 160-. In addition, according to the above calculations, the bandwidth requirements of the three channels are roughly 1: 2: taking 160kbps as an example, when the network bandwidth is greater than or equal to 160kbps (a first threshold), the three data channels all transmit corresponding data; when the network bandwidth is less than 160kbps and greater than or equal to 120kbps (second threshold), the first data channel and the second data channel transmit their corresponding data, and the third data channel does not transmit the data corresponding to the third data channel; when the network bandwidth is less than 120kbps, only the first data channel transmits the corresponding data, and the second data channel and the third data channel do not transmit their corresponding data.
The embodiment of the present disclosure further provides a data transmission apparatus 300, which includes a data acquisition module 301, a data channel determination module 302, and a data transmission module 303. The data acquisition module 301 is configured to acquire video data to be transmitted. The data channel determining module 302 is configured to determine at least one of a first data channel, a second data channel, and a third data channel, where the first data channel corresponds to a first type of data in the video data to be transmitted, the second data channel corresponds to a second type of data in the video data to be transmitted, and the third data channel corresponds to a third type of data in the video data to be transmitted. The data transmission module 303 is configured to transmit data corresponding to at least one data channel through at least one data channel.
In addition, the present disclosure also provides a terminal, including: at least one memory and at least one processor; the memory is used for storing program codes, and the processor is used for calling the program codes stored in the memory to execute the data transmission method.
In addition, the present disclosure also provides a computer storage medium storing program codes for performing the above-described data transmission method.
In some embodiments, by transmitting data in a hierarchical manner, different data are transmitted through different data channels, so that the priority of the transmitted data can be selected, and the data transmission can be optimized. In addition, according to the importance of the data, the most important data is reliably transmitted, the next important data is partially reliably transmitted, and the less important data is unreliable transmitted, so that the weak network resistance is improved, and the QoS is improved. In addition, a large amount of data are transmitted in a UDP mode, the data transmission efficiency is improved, and the key data are transmitted through TCP, so that the data security and the weak network resistance are improved. In addition, when the network is poor, the data channel for transmitting the non-key frame can be discarded step by step, so that the transmitted data volume is reduced, but the transmission of the key data is ensured, so that the data received by the receiving end can still be decoded and played, and the weak network resistance is further improved.
