Estimating the term…
The media session management of the invention encompasses a media server having access to multiple unicast-based media channels and a user terminal. The user terminal generates and transmits a generic, channel-transparent session request to the server. This request initiates a generic, channel-transparent media session setup procedure between the terminal and the server. The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server. Once the channel-transparent setup has been completed, the user terminal transmits a channel-specific rendering request for a desired media channel to the server. In a subsequent channel switch, the terminal simply transmits a new channel-specific request for a new channel to the server during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure.
A method, in a user terminal, of switching media channel in a unicast-based media session involving a user terminal receiving a first media content of a first media channel from a media server providing said first media channel and a second media channel, said method comprising said user terminal transmitting, to said media server, a content-specific rendering request for a second media content of said second media channel during said ongoing unicast-based media session, wherein said content-specific rendering request comprises a unique media content resource identifier associated with said second media content.
A user terminal comprising:
The user terminal according to 4, further comprising a receiver for receiving media content of said second media channel on same input ports as was used by said user terminal for receiving media content of said first media channel.
A media server providing multiple media channels, each media channel carrying a respective media content, said media server comprises:
A method, in a media server, of switching media channel in a unicast-based media session involving a media server transmitting a first media content of a first media channel to a user terminal and providing said first media channel and a second media channel, said method comprising:
