| 摘要 |
The present invention proposes an apparatus and a method for selecting a transport control mechanism to be used between a first device (110) and a second device (120). Firstly, a first unit (231) obtains first information indicating the transport control mechanism supported by the first device (210) and second information indicating the transport control mechanism supported by second device (220); then, a second unit (232) selects the transport control mechanism to be used between the first device (210) and the second device (220) on the basis of the first and second information and a preset rule. With the apparatuses and methods provided in the present invention, the problem of how to select the transport control mechanism to be used between the media server and the media client is well solved. Furthermore, by applying the defined messages and the interaction process in IGRS protocols, there is no need for additional messages nor for an additional interaction process. |

1. An apparatus for selecting a stream transport control mechanism to be used between a first device and a second device, comprising:
a first unit for obtaining first information indicating a stream transport control mechanism supported by the first device and second information indicating a stream transport control mechanism supported by the second device, wherein the stream transport control mechanism comprises both a Simple Object Access Protocol (SOAP) based transport control mechanism and a Back-Channel Message (BCM) based transport control mechanism; and a second unit for selecting the stream transport control mechanism to be used between the first device and the second device on the basis of the obtained first information, the obtained second information, and a preset rule, wherein the preset rule is different as determined based on (i) stream transport control mechanisms supported by the first device as indicated via the obtained first information and (ii) stream transport control mechanisms supported by the second device as indicated via the obtained second information, said second unit selecting only a single mechanism, either SOAP or BCM, to be operative in response to both SOAP and BCM being supported by both the first device and the second device. |
