Abstract

The present disclosure relates to a method and a device for transmitting content to a display device. The content transmission method includes: receiving a display type from a sink device; generating content in view of the display type; and transmitting the generated content to the sink device, wherein the display type includes information indicating a set type of a display of the sink device.

First claim

1 . A method for transmitting, by a source device, content to a sink device, the method comprising:
receiving a display type from the sink device; generating content in view of the display type; and transmitting the generated content to the sink device, wherein the display type comprises information indicating a set type of a display of the sink device.

2 . The method of claim 1 , further comprising establishing a Real-Time Streaming Protocol (RTSP) session with the sink device before receiving the display type.

3 . The method of claim 1 , further comprising negotiating a start of transmission of the content after receiving the display type.

4 . The method of claim 1 , wherein the transmitting of the content further comprises transmitting the content corresponding to a portrait mode when the display of the sink device is set in a portrait form.

5 . The method of claim 1 , further comprising transmitting, to the sink device, a message indicating that the content is scheduled to be transmitted based on the display type.

6 . The method of claim 1 , wherein the display type is received through at least one of a content form request message and a message carrying capability information on the display set in the sink device.

7 . A method for receiving, by a sink device, content from a source device, the method comprising:
transmitting a display type to the source device; receiving content in view of the display type from the source device; and outputting the content through a display, wherein the display type comprises information indicating a set type of the display of the sink device.

8 . The method of claim 7 , wherein the receiving of the content in view of the display type is receiving the content corresponding to a portrait mode when the display of the sink device is set in a portrait form.

9 . The method of claim 7 , further comprising receiving, from the source device, a message indicating that the content is scheduled to be transmitted based on the display type.

10 . The method of claim 7 , wherein the display type is transmitted through at least one of a content form request message and a message carrying capability information on the display set in the sink device.

11 . The method of claim 7 , further comprising receiving the content in a landscape mode from the source device before transmitting the display type,
wherein when the display type of the sink device is a portrait type and the content is in a landscape mode, the content is not played back.

12 . A source device for transmitting content to a sink device, the source device comprising:
a transceiver that receives a display type from the sink device and transmits content to the sink device; and a processor that generates content in view of the display type and controls the transceiver to transmit the generated content to the sink device, wherein the display type comprises information indicating a set type of a display of the sink device.

13 . The source device of claim 12 , wherein the transceiver transmits the content corresponding to a portrait mode when the display of the sink device is set in a portrait form.

14 . A sink device for receiving content from a source device, the sink device comprising:
a display; a transceiver that transmits a display type to the source device and receives content in view of the display type from the source device; and a processor that controls the display to output the content, wherein the display type comprises information indicating a set type of a display of the sink device.

15 . The method of claim 14 , wherein the transceiver receives the content in a landscape mode from the source device before transmitting the display type, and
when the display type of the sink device is a portrait type and the content is in a landscape mode, the content is not played back.
