Abstract
Description
technical field
[0001] The present invention relates to video transmission technology, in particular to a panoramic video transmission method, device, terminal, server and system. Background technique
[0002] Virtual Reality (VR, Virtual Reality) refers to the use of computer technology to simulate a three-dimensional virtual world, allowing users to experience a highly realistic virtual space environment in terms of sight, hearing, touch, and taste. With the rapid development of VR technology, applications such as VR (panoramic) video live broadcast and on-demand video are becoming more and more extensive, which brings users a highly immersive video service experience.
[0003] There are two main technical routes for the online transmission of VR panoramic video: a full-view transmission scheme and a FOV (Field of View) transmission scheme. The so-called full-view transmission solution is to transmit all 360-degree surrounding pictures to the terminal. When the user turns...
Examples
Embodiment 1
[0174] Embodiment 1: 360 video on demand (unicast)
[0175] Figure 6 It is a flow chart of the panoramic video transmission method in Embodiment 1 of the present invention; this embodiment is 360 video FOV on-demand transmission. Without loss of generality, the functional entities involved in this embodiment are described as follows:
[0176] 360 video player: such as a virtual reality head-mounted display device (HDM), which can track the change of the user's perspective and posture, and amplify the image on the micro-display through the visual optical system in front of the user's eyes, thereby providing 360 panoramic video immersive display Effect.
[0177] Streaming media client: such as Dynamic Adaptive Streaming (DASH, Dynamic Adaptive Streaming over HTTP) client, providing access, decoding and caching for media resources such as 360 panoramic video.
[0178] Streaming media server: can be any suitable type of network server, such as a node of a Content Delivery Netw...
Embodiment 2
[0197] Embodiment 2: 360 video live broadcast (multicast)
[0198] Figure 8 It is a flow chart of the panoramic video transmission method in Embodiment 2 of the present invention; this embodiment is 360 video FOV live transmission.
[0199] Step 1: The 360 video player selects and requests to play a 360 video program according to the user's instruction.
[0200] Step 2-Step 3: For the 360 video live broadcast transmitted in multicast mode, each program contains panoramic video file video streams with multiple viewing angles, and each viewing angle corresponds to a multicast group address. The streaming media client requests the streaming media server to return the multicast group list corresponding to the selected 360 video program and the corresponding viewing angle relationship information.
[0201] Step 4-Step 5: In order to transmit the auxiliary FVO video file through unicast mode, the streaming media client requests the streaming media server to return the media d...
