In contrast, when an element is described as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.
Please refer to fig. 1, which is a block diagram illustrating an exemplary embodiment of a multimedia interactive system according to the present application. As shown in fig. 1, the multimedia interaction system 1 includes: the wireless broadcast device 11, the terminal equipment 12 and the cloud server 13. The terminal device 12 may be selectively connected to the wireless broadcasting device 11 wirelessly, and the cloud server 13 is connected to the terminal device 12 through a network (shown in fig. 1 as a cloud shape).
In practical implementations, the wireless broadcasting device 11 may be, but is not limited to, a wireless headset or a wireless electronic device with broadcasting function, such as: intelligent glasses or wireless sound equipment capable of broadcasting; terminal device 12 may be, but is not limited to, a mobile terminal, a tablet computer, a desktop computer, a laptop/notebook computer, or a smart television; the wireless communication protocol between the wireless broadcaster 11 and the terminal equipment 12 may include, but is not limited to, WiFi, bluetooth or ZigBee; the network of the terminal device 12 connected to the cloud server 13 may include, but is not limited to, the internet, a wide area network, a metropolitan area network, a local area network, a VPN network, or a wireless Ad Hoc network (Ad Hoc network).
In this embodiment, the terminal device 12 is configured to establish a connection with the radio broadcasting apparatus 11 and transmit a transcription instruction to the radio broadcasting apparatus 11.
In one embodiment, terminal equipment 12 cannot directly transmit instructions to the wireless broadcaster 11 to which it is wirelessly connected, and therefore, terminal equipment 12 may download and install an application program for controlling wireless broadcaster 11 to transmit the transcription instructions to wireless broadcaster 11 to which it is connected via the application program.
In this embodiment, in the process of playing the video by the terminal device 12, the wireless broadcast device 11, which is connected to the terminal device 12 and receives the transcription instruction, continuously receives and compresses the voice information of the video, so as to continuously return the compressed information to the terminal device 12; the terminal device 12 decompresses the compressed information received in real time to obtain the information to be translated; the terminal device 12 transmits the information to be translated to the cloud server 13 for translation to obtain the text information with the target language; the terminal device 12 displays the text information on the screen of the video played by it. Therefore, the multimedia interactive system 1 can perform the translation function by using the wireless broadcast device 11 as a medium for capturing and transmitting the voice information of the video and the cloud server 13, so that the terminal device 12 can provide the subtitles in the familiar language corresponding to the video watched by the user, thereby improving the experience of the user in watching the video.
In one embodiment, the wireless communication protocol between the wireless broadcasting device 11 and the terminal device 12 may be bluetooth, and therefore, the terminal device 12 may establish a bluetooth Audio Distribution Profile (A2DP) connection with the wireless broadcasting device 11, so that the terminal device 12 may transmit the voice information of the video it is playing to the wireless broadcasting device 11 based on the A2DP connection.
In one embodiment, since the wireless broadcast device 11 needs to return the compressed information to the terminal device 12 while receiving the voice information of the video from the terminal device 12, in order to prevent the wireless broadcast device 11 from returning the compressed information to the terminal device 12, which occupies too much communication bandwidth between the wireless broadcast device 11 and the terminal device 12, and jam the transmission of the voice information transmitted to the wireless broadcast device 11 by the terminal device 12, the transmission of the compressed information from the wireless broadcast device 11 to the terminal device 12 needs to be performed in the time interval of the voice information transmitted to the wireless broadcast device 11 by the terminal device 12. Specifically, the terminal device 12 encapsulates the data of the voice information into individual data packets, and then sequentially transmits the data packets of the voice information to the radio broadcasting device 11 using a communication protocol between the terminal device 12 and the radio broadcasting device 11, since the transmission of the data packet of the voice message has a time gap (that is, the terminal device 12 does not transmit the data packet of the voice message uninterruptedly), the wireless broadcasting device 11 may decapsulate the received data packet of the voice message and compress the information, then encapsulate the compressed information into individual data packets, then, in the time gap of the transmission of the data packet of the voice information, the data packet of the compressed information is sequentially transmitted back to the terminal device 12 by using the communication protocol between the terminal device 12 and the wireless broadcasting device 11 (i.e. the transmission of the data packet of the compressed information is interspersed between the transmission of the data packet of the voice information). That is, the wireless broadcasting device 11 continuously transmits back the packet of the compressed information to the terminal device 12 during the interval of continuously receiving the packet of the voice information.
In one embodiment, the wireless broadcaster 11 may be configured to continuously receive the voice message and compress the voice message with a default compression ratio through a voice compression algorithm. The speech compression algorithm may be any algorithm that can meet the hearing requirement (user satisfaction), such as: g.711a, g.711u, g.729, 324M, etc., the default compression ratio may be, but is not limited to, 16: 1, the actual speech compression algorithm and the default compression ratio can be adjusted according to actual requirements.
In an embodiment, each packet of the compressed information may include a CRC16 check code, and the terminal device 12 is further configured to continuously determine whether the CRC16 check code included in each packet of the compressed information received in real time passes the check, to decompress the packet of the compressed information received in real time that passes the check, and to notify the wireless broadcasting device 11 of retransmission of the packet of the compressed information that fails the check. Therefore, it is possible to prevent the occurrence of a situation in which a subsequent decompression failure occurs due to a transmission error of the compressed information.
In one embodiment, the wireless communication protocol between the wireless broadcasting apparatus 11 and the terminal device 12 may be bluetooth, so that the wireless broadcasting apparatus 11 may also continuously transmit the compressed information back to the terminal device 12 based on Serial Port Profile (SPP) protocol.
In an embodiment, when the terminal device 12 transmits the information to be translated to the cloud server 13 for translation, a language instruction (that is, the language instruction is used to specify the target language) is also transmitted to the cloud server 13, so that the cloud server 13 translates the received information to be translated into the text information in the target language based on the language instruction. Wherein, the target language may be, but not limited to, chinese. In an example, the process of the cloud server 13 translating the received information to be translated into the text information in the target language may include: converting the received information to be translated into character information in the same language as the voice information by a voice to Text (Speech to Text) technology; and translating the text information in the same language as the voice information into the text information in the target language by a text translation technology.
In another embodiment, the target language may be a default language, and therefore, the terminal device 12 only needs to transmit the information to be translated to the cloud server 13 (i.e., does not need to transmit the language instruction to the cloud server 13), and can obtain the text information with the target language returned by the cloud server 13.
In one embodiment, terminal device 12 may display the text message in the form of a floating window on the screen of the video played by the terminal device. In another embodiment, terminal device 12 may directly superimpose the text information onto the picture of the played video in a manner similar to Augmented Reality (Augmented Reality) technology.
