In particular, it relates to a non-physical method that enables multimedia equipment to achieve the effect of remote playback without a guide device, thereby effectively reducing the cost of multimedia playback. Multimedia convergence and playback method without broadcasting device and cloud system.

Generally, when playing on multiple multimedia devices, the multiple multimedia devices are usually connected to the director via wires, and then the director integrates the images to be played by the multiple multimedia devices into one screen, or the director connects to The cloud device integrates the images to be played by multiple multimedia devices into one image, thereby outputting the integrated image from a playback platform.

However, with the current playback method, a director is needed to integrate the pictures to be played by multiple multimedia devices into one picture, which greatly increases the cost of playback.

The main purpose of the present invention is to enable multimedia equipment to achieve long-distance playback without the need for a broadcasting device, thereby effectively reducing the cost of multimedia playback.

In order to achieve the above purpose, the present invention is a multimedia convergence and playback method without a physical broadcasting device and a cloud system, which includes the following steps:

Step 2: Based on the coordinate node, use the DHT KDA algorithm to find the shortest number of connection paths. Multimedia equipment, so that several multimedia equipment with the shortest connection path can form a networking group on the operating platform.

Step 3: Each multimedia device in its networking group sends a connection message based on the user identification code of the operating platform. The connection message is sent to each multimedia device through the DHT KDA algorithm.

Step 4: Make direct and penetrating connections between each multimedia device and the operating platform in a sealed package.

Step 5: After connecting, generate at least one key to the operating platform, so that the operating platform can use the key to decrypt the encrypted package and obtain a random key, so as to use the random key to allow each multimedia device to communicate with the operating platform. The operating platform performs encrypted transmission.

Step 6: The operating platform integrates the output images of each multimedia device into one image and plays it on a playback platform.

In the above-mentioned parallel transmission method of multimedia and complete files, in step 2, each multimedia device also serves as a connecting node, so that each coordinate node and each multimedia device cooperate with each other, and a plurality of nodes are formed in the networking group. Each coordinate node or multimedia device is connected to each other by up to eight coordinate nodes or multimedia devices with the shortest connection paths.

In the above-mentioned multimedia convergence and playback method without a physical broadcasting device and a cloud system, the fourth step is to perform a transparent direct connection using the sealed packet method of the User Data Packet Protocol (UDP).

In the above-mentioned multimedia convergence and playback method without a physical broadcasting device and a cloud system, if the connection fails in step 4, transmission will be carried out through a relay server, and step 4 will continue to be executed until the connection is successful. Then switch to the penetrating direct connection.

In the above-mentioned multimedia convergence and playback method without a physical broadcasting device and a cloud system, the fifth step is to generate a private key and a public key after the connection, so that the private key and the public key are asymmetric. Encrypt and transmit it to the operating platform, so that the operating platform can use the private key and the public key to decrypt the encrypted packet and obtain the random key.

In the above-mentioned multimedia convergence and playback method without a physical broadcasting device and a cloud system, the random key in step 5 enables each multimedia device to perform symmetrically encrypted transmission with the operating platform.

In the above-mentioned multimedia streaming and playback method without a physical broadcasting device and a cloud system, if the connection is interrupted and then reconnected in step 5, a random key will be generated again.
