Abstract
The invention relates to a video self-adaption transmission strategy based on video quality assessment. The video self-adaption transmission strategy based on video quality assessment is characterized in that speeds for a server to send video data are dynamically adjusted by assessing a quality of a video obtained by a client so that the quality of the video received by the client is effectively improved; if the quality of the video is larger than 3000, the client sends a request to the server to request the server to increase the speeds for sending the video data so that the quality of the video received by the client is improved; and if the quality of the video is smaller than or equal to 3000, the client is not interacted with the server. The video self-adaption transmission strategy is simple in method, flexible in implementing and high in efficiencies.
