Embodiment 1

[0061] In Embodiment 1 of the present invention, the Source device and the terminal device are in the same local area network, image 3 It is a schematic diagram of the connection between the Source device and the terminal device in the LAN, such as image 3 As shown, the terminal device does not support the default transmission protocol. The terminal device can be a variety of electronic devices such as mobile phones, tablet computers, and laptops. The Source device and the Sink device support the default transmission protocol. The terminal device communicates with the Source device through a LAN. Connected, the Source device performs multimedia data transmission with the Sink device through a preset transfer protocol.

[0062] Embodiment 1 of the present invention is applied to the Source device side, such as Figure 4 As shown, it specifically includes the following steps:

[0063] S401. The Source device sends a broadcast message according to a preset sending rule,

Embodiment 2

[0087] Corresponding to Embodiment 1, Embodiment 2 of the present invention is applied to the terminal device side, such as Figure 6 As shown, it specifically includes the following steps:

[0088] S601. Receive a broadcast message sent by the Source device according to a preset sending rule,

[0089] Wherein, the broadcast message carries the connection information of the Source device and the service information of the service provided by the Source device.

[0090] Furthermore, preset rules can be set according to actual conditions, for example: regular sending, periodic sending, etc.

[0091] S602. According to the broadcast message received in S601, determine a Source device that meets its own multimedia data transmission requirements.

[0092] Further, in this step, the terminal can determine the source device suitable for itself according to the services that the source device can provide. Wherein, the service information of the service provided by the Source device...

Embodiment 3

[0118] In Embodiment 3 of the present invention, the Source device and the terminal device are in the same wide area network, Figure 9 It is a schematic diagram of the connection between the Source device and the terminal device in the wide area network, wherein the wide area network can be any network based on the fourth generation of mobile communication technology standards (4G, the fourth generation of mobile phone mobile communication technology standards), asymmetric digital subscriber loop (ADSL, Asymmetric Digital Subscriber Line), Ethernet, optical fiber, etc. IP network, such as Figure 7 As shown, the terminal device does not support the preset transmission protocol. The terminal device can be a variety of electronic devices such as mobile phones, tablet computers, and laptops. The Source device and the Sink device are devices that support the preset transmission protocol. The terminal device, server, and Source device Located in the WAN, the server obtains the Sou...

Abstract

The invention provides a multimedia data transmission method and related equipment. The multimedia data sent by terminal equipment is received by Source equipment, the terminal equipment does not support a preset transmission protocol, and the preset transmission protocol is a transmission protocol capable of transmitting the multimedia data played by a preset screen of the Source equipment to Sink equipment in real time for real-time playing carried out through the Sink equipment; the received multimedia data is outputted to the preset screen of the Source equipment for playing; the multimedia data played by the preset screen of the Source equipment is sent through the preset transmission protocol in real time to the Sink equipment for real-time playing carried out through the Sink equipment. Through the method, a problem that equipment which does not support the preset transmission protocol can not transmit videos to the Sink equipment in real time for real-time playing carried out through the Sink equipment in the prior art is solved. The multimedia data transmission method relates to the communication technology field.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multimedia data transmission method and related equipment. Background technique [0002] In the prior art, there is usually the following requirement: to transmit the video played on a terminal with a smaller screen (such as a mobile phone) to a device with a larger screen (such as a TV) for real-time playback, which can be realized through an HDMI cable. Connect the mobile phone to the TV, and transmit the video played on the mobile phone to the TV in real time through the HDMI cable and play it in real time, but the HDMI cable requires a certain cost, and not every two devices have such a hardware cable interface to Real-time transmission and real-time playback of multimedia data. Therefore, a preset transmission protocol has appeared. The preset transmission protocol enables devices to be connected without hardware wires, and can be directly connected to a wireless fi...
