Embodiment Construction
[0044] 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. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] An embodiment of the present invention provides a method for transmitting video data. By detecting the auxiliary indication information in the video code stream, the priority information and size information of the subsequent code stream are obtained, so that the base station can compare the video data according to the obtained priority information and size information. The video code stream is transmitted in a differentiated manner,...

The present invention relates to a video data encoding method and device, the method comprising: acquiring a video file; compressing the acquired video file into a video code stream, the video code stream including a plurality of picture group data; Instruction information is added before each of the multiple group of picture data in the video code stream, and the user terminal or base station learns the priority of each data frame in the group of picture data after the instruction information according to the instruction information. grade and size. The transmission method provided by the embodiment of the present invention obtains the priority information and size information of the subsequent code stream by detecting the auxiliary indication information in the video code stream, so that the base station can perform the video code stream according to the obtained priority information and size information. Differentiated transmission, the handheld terminal can also request differentiated transmission of video data to the base station according to the instruction information in the received video code stream combined with the current channel resource status, so as to improve the user's terminal experience.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a video data transmission method and device. Background technique [0002] Scalable Video Coding (Scalable Video Coding, SVC) is one of the existing video data coding mechanisms, which is characterized by being able to encode the original video into a scalable / layered video code stream. This kind of SVC video code stream has a base layer and several enhancement layers. When the channel bandwidth is limited, the receiving terminal only needs to receive the basic layer to decode and reply a video file that meets the basic quality. In the case of sufficient channel bandwidth, you can consider receiving the enhanced layer to decode and obtain high-quality video files. The SVC video code stream is suitable for application in the LTE system, so that the LTE system can better transmit video data. The LTE system performs differentiated transmission of the SVC video code stream ac...
