Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The inventor finds that a large number of conference room terminals currently do not support 4K coding, 4K video communication or display cannot be achieved, and the video effect is poor. In order to solve the above problems, the inventors have further studied and found that, in general, such conference room terminals can support video encoding up to 1080P resolution, and have no poor decoding capability and can support 4K decoding. Based on the above research, the present invention provides a video communication method, which uses a shot to perform 4K coding. As shown in fig. 1, a video communication method according to an embodiment of the present invention includes: step S1 to step S3.
In step S1, a camera acquires a 4K original video stream, and performs H.265(HEVC) encoding on the 4K original video stream to obtain a 4K video encoded stream. Specifically, the 4K original video stream may be H.265(HEVC) encoded by using H.265(HEVC) encoding.
In step S2, the camera sends the one 4K video encoding stream to the video conference terminal. Wherein the video conference terminal does not have a 4K video coding function. Specifically, the camera can transmit a video coding stream to the video conference terminal through the HD-base T interface.
In step S3, the video conference terminal decodes the 4K video encoded stream. After decoding, the data can be directly displayed on a local display terminal, and can also be forwarded to other interactive terminals according to the needs.
Therefore, the video communication method of the embodiment combines the 4K coding function of the camera and the 4K decoding function of the video conference terminal, so that the video conference terminal without the 4K coding function can support communication or display of the 4K video stream, the video communication effect is improved, the 4K video conference terminal does not need to be upgraded, a large amount of common conference terminals are effectively utilized, and the cost is saved.
Based on the same inventive concept, an embodiment further provides a video communication method, as shown in fig. 2, the method including: step S21 to step S24.
In step S21, a camera acquires a 4K original video stream, and performs H.265(HEVC) encoding on the 4K original video stream to obtain a 4K video encoded stream.
In step S22, the camera sends the one 4K video encoding stream to the first video conference terminal.
In step S23, the first video conference terminal transmits the one 4K video encoding stream to the second video conference terminal through the server. Wherein the first video conference terminal does not have a 4K video coding function.
In step S24, the second video conference terminal decodes the one 4K video encoded stream, and the decoded 4K video encoded stream can be directly displayed on the display terminal connected to the second video conference terminal. Thus, the embodiment can realize double-ended remote 4K video communication.
Based on the foregoing embodiments, the inventor also finds that the camera generally supports encoding one path of 4K video encoded streams, and cannot support encoding multiple paths of streams, so that the camera cannot encode video encoded streams with different resolutions at the same time, and cannot realize layering of video streams with different resolutions below 4K and 4K. In order to solve the problem, an embodiment further provides a video communication method, as shown in fig. 3, the video communication method including: step S31 to step S33.
In step S31, a camera acquires a 4K original video stream and a 1080P YUV original video stream, and performs H.265(HEVC) encoding on the 4K original video stream to obtain a 4K video encoded stream.
In step S32, the camera sends both the 4K video encoding stream and the 1080P YUV original video stream to the video conference terminal through the HD-base T interface. Wherein the video conference terminal does not have a 4K video coding function.
In step S33, the video conference terminal performs h.264svc coding layering on the 1080P YUV original video to obtain a plurality of video coding streams with different resolutions. Specifically, in this step, the YUV original video at 1080P may be subjected to h.264svc coding layering, and optionally, may be divided into three layers, 1080P, 540P and 180P. Thus, the video conference terminal can obtain video encoding streams of four resolutions of 4K, 1080P, 540P and 180P. The video coding stream with the required resolution can be displayed on a local display terminal according to actual requirements, or the video coding stream can be forwarded to an interactive terminal with the need.
Based on the same inventive concept, an embodiment further provides a video communication method, as shown in fig. 4, the video communication method includes: step S41 to step S46.
In step S41, a camera acquires a 4K original video stream and a 1080P YUV original video stream, and performs H.265(HEVC) encoding on the 4K original video stream to obtain a 4K video encoded stream.
In step S42, the camera sends both the 4K video encoding stream and the 1080P YUV original video stream to the first video conference terminal.
In step S43, the first video conference terminal performs h.264svc coding layering on the 1080P YUV original video to obtain a plurality of video coding streams with different resolutions.
In step S44, the first video conference terminal sends both the multiple video encoded streams with different resolutions and the one path of 4K video encoded stream to a server.
In step S45, the server forwards the video coding stream with the corresponding resolution to the second video conference terminal according to the QOS service, where the QOS service records the video communication resolution requirement of the user.
In step S46, the second video conference terminal decodes the video encoded stream.
Therefore, when the video communication resolution requirement in the QOS service of the second video conference terminal is 4K, the second video conference terminal can receive the 4K video under the condition that the second video conference terminal supports 4K decoding and network bandwidth, so that 4K video communication is realized, and through the QOS service, the second video conference terminal can also automatically adjust the resolution of the received video according to the network condition, for example, 1080P or 540P and the like when the network environment is poor.
