20120316662 | SYSTEM AND METHOD FOR PROVIDING CONTENTS THROUGH NETWORK IN DEVICE INCAPABLE OF CONNECTING TO A NETWORK - The present invention relates to a system and method for providing contents through a network in a device incapable of connecting to a network, the system including a contents playback device provided with an audio output port, for playing back the contents; and a dongle device supporting CPNS and attached to the audio output port to enable the contents playback device to operate as a device capable of connecting to a network, for capturing and encoding contents outputted from the contents playback device and providing an external user terminal with the encoded contents through the network. Accordingly, according to the present invention, the contents playback device incapable of connecting to a network is enabled to operate as a device capable of connecting to a network only by attaching the dongle device, and since the dongle device encodes the contents (e.g., sound source data) outputted from the contents playback device in real-time and transfers the encoded contents to an external user terminal through the CPNS protocol, the contents can be shared between the contents playback device and the external user terminal. | 12-13-2012 |
