Abstract
A targeted discovery between a first device and a second device in a network, in particular, a WHDI network, provides discovery for an identified device or a group of identified devices. The targeted discovery determines an identifier for a second device or a group of devices that the second device belongs to, and sends a device discovery message to the second device using the identifier for the second device when the second device is configured to respond to the device discovery message if the device discovery message includes the identifier for the second device. The first device receives a response to the device discovery message from the second device and can start further communication with the second device.
Claims20
A method of device discovery in a digital interface network of a type having a first device configured to receive a multimedia data stream sourced from a second device, the method comprising:
- receiving a device discovery message from the first device at the second device, the device discovery message comprising a device identifier;
- verifying, by the second device, whether the device discovery message comprises a correct device identifier for the second device;
- in response to verifying, by the second device, that the device discovery message comprises a correct device identifier for the second device, sending a response to the device discovery message to the first device, the response comprising an acknowledgment of receipt of the device discovery message;
- receiving a registration key from the first device at the second device subsequent to sending the response to the device discovery message;
- and
- providing by the second device and after receiving the registration key, the multimedia data stream to the first device.
A non-transitory computer-readable storage medium storing instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations for device discovery in a digital interface network of a type having a first device configured to receive a multimedia data stream sourced from a second device, the operations comprising:
- receiving a device discovery message from the first device at the second device, the device discovery message comprising a device identifier;
- verifying, by the second device, whether the device discovery message comprises a correct device identifier for the second device;
- in response to verifying, by the second device, that the device discovery message comprises a correct device identifier for the second device, sending a response to the device discovery message to the first device, the response comprising an acknowledgment of receipt of the device discovery message;
- receiving a registration key from the first device at the second device subsequent to sending the response to the device discovery message;
- and
- providing by the second device and after receiving the registration key, the multimedia data stream to the first device.
A device configured to communicate with other devices on a network and perform device discovery in a digital interface network of a type having another device configured to receive a multimedia data stream sourced from the device, the device comprising:
- a processor configured to:
- receive a device discovery message from the another device, the device discovery message comprising a device identifier;
- verify whether the device discovery message comprises a correct device identifier for the device;
- in response to verifying that the device discovery message comprises a correct device identifier for the device, generate a response to the device discovery message, the response comprising an acknowledgment of receipt of the device discovery message;
- and
- a data storage device configured to store the device identifier;
- and
- a network interface configured to send the response to the device discovery message to the other device, to receive a registration key from the other device subsequent to sending the response to the device discovery message, and to provide by the device and after receiving the registration key, the multimedia data stream to the another device.
