Method and apparatus for managing content distribution over multiple terminal devices in collaborative media system
First Claim
1. A method for managing content distribution in a collaborative media system, wherein a first media data is transmitted over a first channel path to a first media terminal and a second media data relevant to the first media data is transmitted over a second channel path to a second media terminal, the method comprising:
- detecting a quality of the first media data on the first channel path and a quality of the second media data on the second channel path;
when the quality of the first media data is lower than a first value and the quality of the second media data is greater than a second value, transmitting the second media data over the second channel path, instead of the first media data over the first channel path, to the first media terminal; and
wherein the quality of the first media data on the first channel path the quality of the second media data on the second channel path are detected as a function of a priority level of a lost packet and a packet loss rate of each media data.

Abstract
A method and an apparatus for managing content distribution over multiple terminal devices in collaborative media system are provided. In the collaborative media system, a first media data is transmitted over a first channel path to a first media terminal and a second media data relevant to the first media data is transmitted over a second channel to a second media terminal. The method comprises: detecting a quality of the first media data on the first channel path and that of the second media data on the second channel path; upon detection the quality of the first media data being lower than a first predetermined value and that of the second media data being greater than a second predetermined value, transmitting the second media data over the second channel path, instead of the first media data over the first channel path, to the first media terminal (S204).

9. A gateway in a collaborative media system, which receives a first media data and transmits the first media data over a first channel path to a first media terminal and receives a second media data relevant to the first media data and transmits the second media data over a second channel to a second media terminal, the gateway comprising:
-
a processor configured to; detect a quality of the first media data on the first channel path and˜
a quality of the second media data on a second channel path;transmit the second media data over the second channel path, instead of the first media data over the first channel path, to the first media terminal, when the first media data is lower than a first value and the quality of the second media data is greater than a second value; and wherein the quality of the first media data on the first channel path and the quality of the second media data on the second channel path are a function of a priority level of a lost packet and a packet loss rate of each media data. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
