[0002] Currently, in scenarios where a user terminal requests RTC (Real-time Communication) media stream services from a cloud platform, the user terminal first establishes an RTC connection with the server in the cloud platform. After the RTC connection is successfully established, the server sends the RTC media stream to the user terminal. Summary of the Invention

[0004] Accordingly, this disclosure provides a media stream transmission control scheme. During the process of establishing an RTC connection between the user terminal and the server, the server sends the corresponding media stream segments to the user terminal for playback through a signaling channel, so that the user can watch the media stream before the RTC connection is established. This effectively shortens the long playback response time of the RTC media stream and improves the user experience.

[0034] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure.

[0036] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] Figure 1 This is a schematic flowchart illustrating a media stream transmission control method according to an embodiment of the present disclosure. In some embodiments, the following media stream transmission control method is executed by a server.

[0041] In step 101, the media stream identifier, first duration information and second duration information are extracted from the RTC connection establishment request sent by the user terminal through the signaling channel, wherein the first duration information is greater than the second duration information.

[0042] In some embodiments, the first duration is the sum of the historical maximum values ​​of the preparation time for establishing an RTC connection, the confirmation time for establishing an RTC connection, and the transmission delay and propagation delay for transmitting the RTC media stream. The second duration is the sum of the historical average values ​​of the preparation time for establishing an RTC connection, the confirmation time for establishing an RTC connection, and the transmission delay and propagation delay for transmitting the RTC media stream.

[0043] In step 102, the first media stream segment and the second media stream segment associated with the media stream identifier are extracted in chronological order, wherein the playback duration of the first media stream segment is the first duration, and the playback duration of the second media stream segment is the difference between the first duration and the second duration.

[0044] In some embodiments, the first rate at which the first media stream segment is transmitted is greater than a preset transmission rate, and the second rate at which the second media stream segment is transmitted is less than the preset transmission rate.

[0045] For example, the first rate is 1.1-1.2 times the normal transmission rate, and the second rate is 0.8-0.9 times the normal transmission rate.

[0046] In step 103, an RTC connection response is sent to the user terminal through the signaling channel so that the user terminal is ready to establish an RTC connection.

[0047] In step 104, the first media stream segment and the second media stream segment are sequentially sent to the user terminal for playback via the signaling channel.

[0048] For example, such as Figure 2 As shown, the media stream segments transmitted through the signaling channel include a first media stream segment and a second media stream segment. The first media stream segment is transmitted at an accelerated speed, while the second media stream segment is transmitted at a decelerated speed. Because the first media stream segment is transmitted at an accelerated speed, the user terminal can play the media stream content as early as possible.

[0049] Furthermore, the playback duration of the first media stream segment is the first duration, and the playback duration of the second media stream segment is the difference between the first and second durations. Normally, the RTC connection will be established within the first duration, meaning the user terminal will receive the RTC media stream within that timeframe. If the user terminal does not receive the RTC media stream within the first duration, the second media stream segment will continue playing to prevent situations where the user terminal is unable to play the media stream.

[0050] In step 105, after receiving the confirmation information for establishing an RTC connection sent by the user terminal, the RTC media stream associated with the media stream identifier is sent to the user terminal for playback through the service channel.

[0051] It should be noted that once the user terminal receives the RTC media stream, regardless of whether it is currently playing the first or second media stream segment, it will not continue playing; instead, it will immediately start playing the RTC media stream.

[0052] In the media stream transmission control method provided in the above embodiments of this disclosure, during the establishment of an RTC connection, media stream segments are sent to the user terminal for playback via a signaling channel. As a result, the user can watch the media stream before the RTC connection is established, thereby effectively shortening the playback response time of the RTC media stream, which is relatively long, and improving the user experience.

[0055] In some embodiments, the first rate at which the first media stream segment is transmitted is greater than a preset transmission rate, and the second rate at which the second media stream segment is transmitted is less than the preset transmission rate.

[0056] In some embodiments, the first duration is the sum of the historical maximum values ​​of the preparation time for establishing an RTC connection, the confirmation time for establishing an RTC connection, and the transmission delay and propagation delay for transmitting the RTC media stream. The second duration is the sum of the historical average values ​​of the preparation time for establishing an RTC connection, the confirmation time for establishing an RTC connection, and the transmission delay and propagation delay for transmitting the RTC media stream.

[0057] The second processing module 32 is configured to send an RTC connection response to the user terminal through a signaling channel, and sequentially send the first media stream segment and the second media stream segment to the user terminal for playback through the signaling channel.

[0058] The third processing module 33 is configured to send the RTC media stream associated with the media stream identifier to the user terminal for playback via the service channel after receiving confirmation information from the user terminal to establish an RTC connection.
