Abstract
In a method for transmission of video information between HTTP servers and clients in a shared network resource, particularly Internet, the video information is stored as a video file consisting of packet-divided video streams compression-coded with average bit rates t(c) which cover the clients' expected channel bit rates s. Each packet and the video file are supplied with a header containing information for realizing a bandwidth-scalable video transmission over a suitable version of HTTP. During transmission switching between the video streams takes place on the basis pf an estimation of the channel bit rate s and the information in the packet header, such that the bit rate t(c) is adapted to the client's actual channel bit rate s. In a method for client-executed search and retrieval of video information in a shared network resource, particularly searching of a video frame Fx in a packet-divided video stream, the packets in a video stream are divipacket packet in each group. On basis of given search criteria and search-specific information in the packet headers the packet with the video five Fx is found, such that a pseudo-random search and retrieval are realized with the use of a suitable version of HTTP as transport protocol.
