Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Aiming at 3D video transmission, the present invention proposes a transmission path selection method based on energy consumption awareness under software-defined network. At the information source coding end, a scalable 3D video code stream is used, that is, the video and depth are coded separately by scalable coding, and a depth and video code stream with a scalable code rate is generated. In this way, multiple code streams with different code rates can be transmitted through different transmission paths under the software-defined network. Finally aggregated at the receiving end. Given a ...

The invention discloses a 3D video transmission method based on software-defined networking energy consumption perception. The method comprises: 1) a source coding end codes 3D video to be transmitted by adopting a scalable 3D video code to generate code stream with scalable code rate, wherein the code stream comprises depth data code stream and 2D video code stream; 2) a controller determines the quantity of the 2D video code stream and the depth data code stream to be transmitted according to the available bandwidth of a network, wherein the sum of the quantity of the 2D video code stream and the depth data code stream is np; then the controller selects available transmission paths meeting the bandwidth requirement from the network according to the bandwidth obtained by coding in step 1), and selects a transmission path with optimal energy consumption for each code stream from the available transmission paths to obtain a group of transmission paths; and 3) transmitting the code stream to be transmitted to a destination end according to the group of transmission paths. The method can reduce the energy consumption in the 3D video transmission process, reduce the operation cost and improve the 3D video transmission performance.
Description
technical field [0001] The invention belongs to the field of network technology and multimedia communication, and relates to a 3D video transmission method based on software-defined network energy consumption perception. Background technique [0002] In recent years, 3D video has been widely used commercially in theaters, and has gradually entered households in the form of 3D TV. At present, in addition to Blu-ray discs, broadcasting and other transmission forms, Internet video transmission is an economical and simple 3D video distribution method. The 2D video distributed on the Internet has already caused a lot of transmission pressure on the network, while the 3D video involves multiple channels of video data, and the huge amount of data has caused even greater pressure on the Internet. [0003] At present, the rapid growth of Internet traffic makes it difficult for the existing network protocol structure to meet the quality requirements of actual business applications. ...
