The invention discloses a method and a device for cross-layer optimization in multimedia communication with different user terminals. A method for bi-directionally converting content and routing it todifferent devices includes: receiving first multimedia content originating from a first device located outside a home location and destined for a second device located at the home location; converting the first multimedia content so that it can be played by the second device, and routing the converted first multimedia content to the second device; receiving a second multimedia content originatingfrom a third device located at the home location and destined for a fourth device located outside the home location; and converting the second multimedia content so that it can be played by the fourth device, and routing the converted second multimedia content to the fourth device. Various optimizations of delivery of multimedia content on different channels are simultaneously provided to a plurality of user terminals.
