Data e.g. scalable video coding image, transmitting method for client, involves transmitting layer of priorities at required switching during reception of request for switching between initial and target spatial resolutions from client

摘要

The method involves determining switching between two levels of different spatial resolution, and generating a scalability layer of priorities at the level of spatial resolution in the absence of switching. The scalability layer of priorities is generated in the switching, and the scalability layer of priorities is transmitted at the required switching during reception of a request for switching between the level of initial spatial resolution and a level of target spatial resolution from a part of client. Independent claims are also included for the following: (1) a device for transmitting data between a server and a client (2) a computer program comprising a set of instructions for implementing a method for transmitting data between a server and a client (3) a information medium comprising a set of instructions for implementing a method for transmitting data between a server and a client.
