Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
The embodiment of the invention provides a data hybrid transmission method, a data hybrid transmission device, electronic equipment and a computer readable storage medium. Specifically, the embodiment of the invention provides a data hybrid transmission method suitable for a data hybrid transmission device, and the data hybrid transmission device can be integrated in electronic equipment.
The electronic device may be a terminal or the like, including but not limited to a mobile terminal and a fixed terminal, for example, a mobile terminal including but not limited to a smart phone, a smart watch, a tablet computer, a notebook computer, a smart car, etc., wherein the fixed terminal includes but not limited to a desktop computer, a smart television, etc.
The electronic device may be a server, which may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligence platforms, but is not limited thereto.
The data hybrid transmission method of the embodiment of the invention can be realized by a server or a terminal and the server together.
The method for implementing the data hybrid transmission by the terminal and the server together is described below as an example.
As shown in fig. 1, the data hybrid transmission system provided by the embodiment of the present invention includes a terminal 10, a server 20, and the like; the terminal 10 and the server 20 are connected through a network, for example, a wired or wireless network connection, wherein the terminal 10 may exist as a terminal for a user to acquire broadcast transmission data and download target transmission data.
Among them, the server 20 may be used to transmit data transmission description information of broadcast transmission data and burst transmission data to the terminal 10.
The terminal 10 may acquire data transmission description information of the burst transmission data, including available time information for at least two data bursts of the burst transmission data, and broadcast transmission data, and determine whether a first burst and a second burst of the data bursts are expired based on the available time information in the data transmission description information.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
The embodiments of the present invention will be described from the perspective of a data hybrid transmission apparatus, which may be integrated in a server or a terminal in particular.
As shown in fig. 2, the specific flow of the data hybrid transmission method of this embodiment may be as follows:
201. and acquiring data transmission description information of the data transmitted in the fragments and broadcasting the data transmitted in the fragments, wherein the data transmission description information comprises available time information of at least two data fragments of the data transmitted in the fragments.
The fragmented transmission data refers to data transmitted in a fragmented form through an internet broadband. Since the link layer has a maximum transmission unit (Maximum Transmission Unit, MTU), when the data packet is larger than the link maximum transmission unit, the data packet can be broken up into a number of data fragments to enable data transmission over the link layer.
In some embodiments, the data transmission description information may be information describing the data for the segment transmission, for example, the data transmission description information may include, but is not limited to, available time information for each data segment in the segment transmission data, uniform resource locators (Uniform Resource Locator, URLs) for downloading each data segment, and/or address information of an electronic device receiving the data transmission description information, and so on.
For example, in an embodiment of the present invention, the data transmission description information may be in the form of a media presentation description (Media Presentation Description, MPD) table. In ATSC3.0, the MPD table may carry both related audio and video information of broadcast transmission and network audio and video information. The MPD table may describe the available time information of the segments and URLs corresponding to the network audio and video.
It will be appreciated that the data transmission description information may be any form that may be implemented to describe the data to be transmitted in slices, which is not limited in this embodiment of the present invention.
The broadcast transmission data is data transmitted through a Radio Frequency (RF) signal.
In the embodiment of the invention, the broadcast transmission data and the sliced transmission data can be limited to meet the standard of advanced television services committee (Advanced Television Systems Committee, ATSC) 3.0, and the broadcast transmission data and the sliced transmission data can be transmitted by adopting the dynamic self-adaptive streaming technology based on HTTP under the standard of ATSC 3.0.
Among them, ATSC3.0 is a national standard of digital television in the united states, and dynamic adaptive streaming over HTTP (Dynamic Adaptive Streaming over HTTP, DASH) is an adaptive bit rate streaming technology, so that high quality streaming media can be delivered through a conventional HTTP web server over the internet.
Specifically, the available time information indicates the valid time of the corresponding data fragment, for example, the available time information may be a certain time, which indicates that the data fragment corresponding to the available time information is valid (not expired) before the time; alternatively, the available time information may be a time period, which indicates that the data slice corresponding to the available time information is valid in the time period; alternatively, the available time information may be a time and a period of time, indicating that the data fragment corresponding to the available time information is valid for the period of time after the time, and so on.
It will be appreciated that the available time information corresponding to different data slices may be the same or different, e.g. the available time information of data slice 1 indicates a valid time of 10 seconds for a data slice, the available time information of data slice 2 indicates a valid time of 15 seconds for a data slice, etc. The embodiment of the present invention is not limited thereto.
202. And determining whether a first fragment and a second fragment of the data fragments are out of date based on the available time information in the data transmission description information.
Wherein the first and second slices are two different data slices in the sliced transmission data. For example, the first slice may be a data slice (first data slice) located at a first bit in the transmission order in the sliced transmission data, and the second slice may be a data slice (last data slice) located at a last bit in the transmission order in the sliced transmission data; alternatively, the first slice is any one of the data slices in the slice transmission data, the second slice is another one of the data slices other than the first slice in the slice transmission data, and so on.
In the practical application process, the correlation between a certain data slice and the audio/video data currently being played gradually decreases with the passage of time. To ensure correlation between the data slices, a validity period may be set for each data slice. When the storage time or transmission time of the data fragment exceeds a preset validity period, the data fragment can be considered to have expired.
203. And if the first and second fragments are expired, acquiring the current transmission object identification of the broadcast transmission data.
The transmission object identifier can be used for identifying an object currently transmitted in broadcast transmission data. For example, the transport object identification may be a transport object identifier (transport object identifier, TOI), or the like.
For example, broadcast transmission data may be in the form of a code stream, a length of which may be composed of a number of media or signaling objects, each of which may have a unique transmission object identification.
204. And determining target transmission data corresponding to the broadcast transmission data from the fragmented transmission data based on the transmission object identification, and downloading the target transmission data.
The target transmission data is data which can be corresponding to the broadcast transmission data in the fragment transmission data. For example, the broadcast transmission data may be audio data, the target transmission data may be video data synchronized with the portion of the audio data, and so on.
The determination of whether the first and second slices of the data slice are expired based on the available time information in the data transmission description information in step 202 is described in detail below.
In some optional embodiments, the available time information includes an available start time of each data slice, and the step of determining whether the first slice and the second slice in the data slice expire based on the available time information in the data transmission description information may specifically include:
acquiring a current standard time and available starting time corresponding to a first fragment and a second fragment in the data fragments respectively;
calculating a first time difference value between the current standard time and the available starting time of the first slice and a second time difference value between the current standard time and the available starting time of the second slice;
And determining whether the first and second fragments expire or not based on the first time difference value, the second time difference value and a preset time difference value threshold.
The current standard time may be coordinated universal time (Universal Time Coordinated, UTC), or beijing time, among others. The current standard time may be calculated with the available start time.
It will be appreciated that the time difference threshold may be a range of values, for example 10 ms to 100 ms, where the first slice may be considered unexpired if the first time difference is within the time difference threshold; alternatively, the time difference threshold may be a critical value, such as a maximum value, if the second time difference is greater than the critical value, the second slice may be deemed to be expired, and so on.
When there is an unexpired data fragment, the unexpired data fragment can be directly downloaded, as shown in fig. 3. The data hybrid transmission method provided by the embodiment of the invention can further comprise the following steps:
if at least one of the first and second fragments is not expired, determining whether each data fragment is expired based on available time information corresponding to each data fragment in the fragment transmission data;
Taking unexpired data fragments in the data fragments as target transmission data;
and downloading the target transmission data.
By directly downloading unexpired data fragments, computing resources for determining target transmission data from broadcast transmission data can be saved.
The following describes in detail the downloading of the target transmission data, which is determined from the fragmented transmission data based on the transmission object identifier in the step 204 and corresponds to the broadcast transmission data.
In the actual application process, it may be determined whether or not there is a data fragment corresponding to the broadcast transmission data currently being transmitted among the data fragments that have expired in combination with the broadcast transmission data. The broadcasting transmission data and the slicing transmission data are mutually referred, so that the accuracy of downloading data slicing can be improved, and the effect of synchronizing audio and video can be further achieved.
As shown in fig. 4, if the broadcast transmission data is still being transmitted in the case where all the data slices have expired, it can be considered that there are more data slices to be downloaded among the expired data slices. Therefore, it is necessary to determine whether broadcast transmission data is still in a transmission state.
Correspondingly, the step of determining, based on the transmission object identifier, target transmission data corresponding to the broadcast transmission data from the fragmented transmission data includes:
comparing the current transmission object identifier with the acquired previous transmission object identifier;
and if the current transmission object identifier is different from the previous transmission object identifier, determining target transmission data corresponding to the broadcast transmission data from the sliced transmission data according to the current transmission object identifier.
If the current transmission object identifier is different from the previous transmission object identifier, the transmission object identifier is considered to be updated, and the broadcast transmission data is still in a transmission state.
It can be appreciated that there may be a certain delay in the transmission of data, and if it is determined that the current transmission object identifier of the broadcast transmission data is different from the previous transmission object identifier at a time, the transmission object identifier may be acquired again after a period of time.
That is, the data hybrid transmission method provided by the embodiment of the present invention may further include:
if the current transmission object identifier is the same as the previous transmission object identifier, acquiring a new transmission object identifier as the current transmission object identifier after a preset time interval, wherein if the current transmission object identifier is the first transmission object identifier, judging that the current transmission object identifier is the same as the previous transmission object identifier;
And returning to the step of comparing the current transmission object identification with the acquired previous transmission object identification.
The first transmission object identifier is the transmission object identifier of the first broadcast transmission data received or acquired in the data mixed transmission process.
The preset time interval may be set by a technician according to practical situations, for example, several hundred milliseconds, etc., which is not limited in the present invention.
The determining, based on the transmission object identifier, target transmission data corresponding to the broadcast transmission data from the fragmented transmission data, and downloading the target transmission data includes:
determining a data fragment corresponding to the transmission object identifier from the fragmented transmission data as target transmission data based on the transmission object identifier and a preset corresponding relation between the transmission object identifier and the data fragment identifier;
constructing a data fragment downloading address corresponding to the target transmission data;
and downloading the target transmission data through the data fragment downloading address.
For example, the TOI may be used as an identifier (segment number) corresponding to the target transmission data to be filled in the URL, and after the TOI is determined, the TOI is equivalent to the target transmission data determined, and the TOI is filled in the URL to obtain the data fragment download address.
In the practical application process, the data hybrid transmission method provided by the embodiment of the invention can further comprise the following steps:
carrying out data analysis on the downloaded target transmission data to obtain a target data fragment identifier of the target transmission data;
verifying the target data fragment identifier based on the transmission object identifier and the corresponding relation between the preset transmission object identifier and the data fragment identifier;
and if the target data slicing identifier is inconsistent with the data slicing identifier corresponding to the transmission object identifier, returning to execute the step of determining the target transmission data corresponding to the broadcast transmission data from the sliced transmission data based on the transmission object identifier, and downloading the target transmission data.
By verifying the target data fragment identification, if conditions such as irregular MPD table production exist, the abnormality can be identified and target transmission data can be redetermined, so that correction of error data is realized, and the robustness of a product can be improved.
As can be seen from the foregoing, in the embodiment of the present invention, data transmission description information and broadcast transmission data of the data to be transmitted in the segments may be obtained, where the data transmission description information includes available time information of at least two data segments of the data to be transmitted in the segments, whether a first segment and a second segment of the data segments are expired is determined based on the available time information in the data transmission description information, if the first segment and the second segment are expired, a current transmission object identifier of the broadcast transmission data is obtained, and based on the transmission object identifier, target transmission data corresponding to the broadcast transmission data is determined from the segment transmission data, and the target transmission data is downloaded; because the broadcast transmission data and the sliced transmission data are transmitted simultaneously in the embodiment of the invention, when the data in the sliced transmission data is out of date, the sliced transmission data is not skipped directly, but the target transmission data is determined from the sliced transmission data according to the broadcast transmission data to download, therefore, the non-real-time audio and video data can be normally transmitted, the stability of audio and video playing is improved, and the problem of abnormal playing caused by the incapability of downloading due to the expiration of the data sliced is solved.
