Problems solved by technology

However, there are two main problems in the current system: one is that too many VCR operations will increase the burden on the system, no matter it is the traditional server-client mode or the popular point-to-point mode; on the other hand, the current The operation of the VCR simply provides 2x, 4x or 8x operation modes, which makes it difficult for users to quickly find the part they are interested in

Embodiment Construction

[0026] The present invention is further described below by an example.

[0027] by Figure 4 Take the case in as an example, node C( Figure 4-2 2) is a newly added node to the system, and node A already exists in the system ( Figure 4-2 0) and B( Figure 4-2 1), they have the same request interest as node C.

[0028] 1. The system first initializes, and the media server ( Pic 4-1 9) There are video resources saved on it ( Figure 4-2 3), and perform preprocessing to generate keyframe files ( Figure 4-2 4).

[0029] 2. When a new user node C joins the system and is ready to watch, it first sends a video request to the server ( Figure 4-3 1). The server responds to the request ( Figure 4-3 2) and transfer the index file SI ( Figure 4-3 0). After node C obtains the scene index part in the key frame file, it can display the key frames of each scene in the player, and can choose to jump to some scenes according to the viewing interest.

[0030] 3. When starting n...

Abstract

The invention belongs to network stream media technical field, particularly a video partition technology based stream media distributing mode and user VCR operation. The stream media distributing mode and user VCR operation (comprising play, pause, interim, speedup and fast backward etc.) dependent on the video partition technology comprises the following two parts contents: one is changing traditional video distributing mode with video frame as unit; two is providing new speedup and fast backward operation, no longer the modes of simple 2X, 4X or 8X etc., but according to the result of video partition, providing new speedup and fast backward operation based on camera and scene, which is convenient for the use of user greatly.

Description

technical field [0001] The invention belongs to the technical field of network streaming media, and in particular relates to the distribution of streaming media and the VCR operation method for users. Background technique [0002] With the development and popularization of network technology, resources on the network are becoming more and more abundant, and they are changing people's lifestyles, and network streaming media is one of the important aspects. In the traditional mode, people watch video programs relying on the push of TV stations, which is a passive viewing mode; while network streaming media allows users to choose programs independently, and provides operations such as fast forward and rewind (that is, VCR operation) Meet the needs of users. However, there are two main problems in the current system: one is that too many VCR operations will increase the burden on the system, no matter it is the traditional server-client mode or the popular point-to-point mode; ...
