Abstract
Disclosed is a method for hybrid transmission over a broadcast network and a broadband network, comprising the steps of: providing information on the broadcast content relating to a first content during the viewing the first content of the broadband network; and, if the related broadcast content is selected, providing the related broadcast content to a user over the broadcast network. The user may receive the broadcast content corresponding to relevant specific content over the broadcast network and view the received broadcast content during the viewing of specific VOD content in the broadcast network.
Claims31
A hybrid transmission method which uses heterogeneous network including at least one of a broadcast network or a broadband network, the hybrid transmission method comprising:
- transmitting an MPEG Multimedia Transport (MMT) packet of a first content through the heterogeneous network,
- wherein the transmitting the MMT packet of the first content further comprises:
- generating media processing unit (MPU) by encapsulating media fragment unit (MFU) being smaller than an access unit (AU) and contained data processed by a media decoder, the MPU being a container for independently decodable timed or non-timed data;
- generating an MMT asset based on at least one MPU, the MMT asset being a logical grouping of MPUs that share the same asset ID;
- generating MMT package including at least one MMT asset, the composition information (CI) and transport characteristics (TC);
- and
- generating MMT packet by adding an MMT packet header to MMT payload generated by referring to the MMT package,
- wherein the composition information comprises information on spatial and temporal relationship among the MMT assets, and
- the MPU comprises an MMT hint track including information on converting the encapsulated MPU into the MMT payload and MMT packet, and
- wherein the MMT hint track provides hint for extracting and building of the MFU for encapsulation using the MMT payload format.
A hybrid reception method which uses heterogeneous network including at least one of a broadcast network or a broadband network, the hybrid reception method comprising:
- receiving an MPEG Multimedia Transport (MMT) packet of a first content through the heterogeneous network,
- wherein the MMT packet is generated by
- generating media processing unit (MPU) by encapsulating media fragment unit (MFU) being smaller than an access unit (AU) and contained data processed by a media decoder,
- generating an MMT asset based on at least one MPU,
- generating MMT package including at least one MMT asset, the composition information (CI) and transport characteristics (TC), and
- adding an MMT packet header to MMT payload generated by referring to the MMT package, the MPU being a container for independently decodable timed or non-timed data and the MMT asset being a logical grouping of MPUs that share the same asset ID,
- wherein the composition information comprises information on spatial and temporal relationship among the MMT assets,
- wherein the MPU comprises an MMT hint track including information on converting the encapsulated MPU into the MMT payload and MMT packet, and
- wherein the MMT hint track provides hint for extracting and building of the MFU for encapsulation using the MMT payload format.
A hybrid transmission device which uses heterogeneous network including at least one of a broadcast network or a broadband network, the hybrid transmission device comprising:
- at least one processor that executes non-transitory computer program code stored on storage media, wherein the non-transitory computer program code includes instructions to execute:
- receiving an MPEG Media Transport (MMT) payload, and generating an MMT packet by
- generating media processing unit (MPU) by encapsulating media fragment unit (MFU) being smaller than an access unit (AU) and contained data processed by a media decoder,
- generating an MMT asset based on at least one MPU,
- generating MMT package including at least one MMT asset, the composition information (CI) and transport characteristics (TC), and
- adding an MMT packet header to MMT payload generated by referring to the MMT package, the MPU being a container for independently decodable timed or non-timed data and the MMT asset being a logical grouping of MPUs that share the same asset ID;
- and
- transmitting the generated MMT packet,
- wherein the composition information comprises information on spatial and temporal relationship among the MMT assets, and
- the MPU comprises an MMT hint track including information on converting the encapsulated MPU into the MMT payload and MMT packet, and
- wherein the MMT hint track provides hint for extracting and building of the MFU for encapsulation using the MMT payload forma.
A hybrid reception device which uses heterogeneous network including at least one of a broadcast network or a broadband network, the hybrid reception device comprising:
- at least one processor that executes non-transitory computer program code stored on storage media, wherein the non-transitory computer program code includes instructions to execute:
- receiving an MPEG Media Transport (MMT) packet of a first content,
- wherein the MMT packet is generated by
- generating media processing unit (MPU) by encapsulating media fragment unit (MFU) being smaller than an access unit (AU) and contained data processed by a media decoder,
- generating an MMT asset based on at least one MPU,
- generating MMT package including at least one MMT asset, the composition information (CI) and transport characteristics (TC), and
- adding an MMT packet header to MMT payload generated by referring to the MMT package, the MPU being a container for independently decodable timed or non-timed data and the MMT asset being a logical grouping of MPUs that share the same asset ID and the MMT asset being a logical grouping of MPUs that share the same asset ID,
- wherein the composition information comprises information on spatial and temporal relationship among the MMT assets, and
- the MPU comprises an MMT hint track including information on converting the encapsulated MPU into the MMT payload and MMT packet, and
- wherein the MMT hint track provides hint for extracting and building of the MFU for encapsulation using the MMT payload format.
