Problems solved by technology

When the network environment where the client is located is relatively congested and the bandwidth is low, the probability of this situation will be greatly increased
At this time, the transmission of a large amount of invalid data will occupy precious bandwidth resources, further reducing the actual effective dat

Embodiment Construction

[0043] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same or similar components or elements.

[0044] The uncompressed original video data has a very large amount of information, and it is inconvenient to store them directly or transmit them through the network. It usually needs to be compressed and encoded using various video coding technologies. In the current common video coding methods, most of them are based on intra-frame coding, motion estimation, and compensation compression strategies. In terms of frame formation strategies, most of them also form concepts similar to I frame (intra-frame coding frame), P frame (inter-frame coding frame), B frame (bidirectional predictive frame) or similar concepts. Although only when all these frames are complete can a complete video picture be seen, but...

Abstract

The invention discloses a network video streaming media system, a transmission processing method, a transmitting end and a receiving end. The method comprises the following steps that: the transmitting end determines the priority of a data packet according to the type of a video frame in the data packet of network video streaming media, and transmits higher-priority data packet of the network video streaming media preferentially; the receiving end resorts the received data packet of the network video streaming media so as to recover an original sequence of the data packet of the network video streaming media; and the receiving end plays the data packet of the network video streaming media, of which the sequence is reduced. In the network video streaming media system and the network video streaming media method, encoding characteristics based on a network video streaming media video coding format and transmission characteristics are optimized; on one hand, the condition that a client playing effect is sharply deteriorated and cannot be improved in a long time in case of insufficient data is effectively avoided; and on the other hand, a condition that a player frequently repeats buffering waiting time in a scheme of simultaneously compressing multi-rate data in the process of switching between different code rates is avoided.

Description

technical field [0001] The invention relates to the technical field of network streaming media, in particular to a network video streaming media system, a transmission processing method, a sending end and a receiving end. Background technique [0002] Network streaming media refers to playing media formats, such as audio, video or multimedia files, etc. in the network by means of streaming transmission. By segmenting or encoding these data in a certain way, they become a series of small data packets, which are transmitted to the client through network transmission technology, and the client restores the received data packets into original files or data according to the protocol. flow, and then apply it according to its actual use. [0003] In the traditional network streaming media technology, the data received by each node is usually sent to the network in full, so that the client can obtain complete data. But in some specific network streaming media applications, such as...
