Abstract
A method and apparatus of transmitting video content compressed by a codec to a second device is provided. The method includes: transmitting a codec selection request frame to the second device, the codec selection request frame includes an identifier of at least one codec to be used to compress the video content and requests approval of the use of the at least one codec; receiving a codec selection response frame from the second device, the codec selection response frame includes approval information indicating whether the use of the at least one codec is approved; and transmitting video content compressed by the at least one codec to the second device based on the codec selection response frame.
Claims21
A method of transmitting media content by a first device, the method comprising:
- receiving, from a second device, a capability response frame comprising a first identifier that identifies at least one codec supported by the second device;
- transmitting, from the first device, a codec selection request frame to the second device, the codec selection request frame comprising a second identifier that identifies a plurality of codecs to be used to compress at least one media content;
- receiving, at the first device, a codec selection response frame from the second device, the codec selection response frame comprising approval information indicating whether use of at least one codec of the plurality of codecs is approved;
- and
- transmitting, from the first device, the at least one media content compressed by the plurality of codecs to the second device based on the codec selection response frame,
- wherein the codec selection request frame further comprises at least one content identifier indicating media content to be transmitted by the first device and content number information indicating an amount of media content to be transmitted by the first device.
An apparatus that transmits media content, the apparatus comprising:
- a receiver configured to receive, from an second device, a capability response frame comprising a first identifier that identifies at least one codec supported by the second device;
- and
- a transmitter configured to transmit a codec selection request frame to the second device, the codec selection request frame comprising a second identifier that identifies a plurality of codecs to be used to compress at least one media content,
- wherein the receiver is further configured to receive a codec selection response frame from the second device, the codec selection response frame comprising approval information indicating whether use of at least one codec of the plurality of codecs is approved,
- wherein the transmitter is further configured to transmit the at least one media content compressed by the plurality of codecs to the second device based on the codec selection response frame, and
- wherein the codec selection request frame further comprises at least one content identifier indicating the at least one media content to be transmitted by the apparatus and content number information indicating an amount of the at least one media content to be transmitted by the apparatus.
A non-transitory computer-readable recording medium having embodied thereon a computer program, which when executed by a computer, performs a method comprising:
- receiving, by a first device, a capability response frame from a second device, the capability response frame comprising a first identifier that identifies at least one codec supported by the second device;
- transmitting, from the first device, a codec selection request frame to the second device, the codec selection request frame comprising a second identifier that identifies a plurality of codecs to be used to compress at least one media content;
- receiving, at the first device, a codec selection response frame from the second device, the codec selection response frame comprising approval information indicating whether use of the at least one codec of the plurality of codecs is approved;
- and
- transmitting, from the first device, the at least one media content compressed by the plurality of codecs to the second device based on the codec selection response frame,
- wherein the codec selection request frame further comprises at least one content identifier indicating media content to be transmitted by the first device and content number information indicating an amount of media content to be transmitted by the first device.
