Abstract

Digital broadcast receiving method comprising receiving base and additional view video streams and stereoscopic characteristics information. The method comprising identifying a virtual channel carrying a 3D broadcast service delivering additional and base view video streams encoded using different codecs using a service type field, wherein the service type field is included in a TVCT of a PSIP in an ATSC-type digital broadcast and identifying a codec type of each of the base and the additional view video streams using a stream type field included in a PMT, wherein the stream type field is related to each of the base and the additional view video streams, and wherein a value of the stream type field indicates the codec type of each of the base and the additional view video streams. The method also comprising processing base and additional view video streams for supporting the 3D broadcast service using the TVCT.

Claims

1. A method comprising:

receiving a base view video stream, an additional view video stream and information regarding stereoscopic characteristics,

identifying a service type field included in a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in Advanced Television Systems Committee (ATSC) type digital broadcast,

wherein the service type field indicates that a virtual channel carries a 3D broadcast service that delivers the additional view video stream and the base view video stream encoded using different codecs;

identifying at least one descriptor included in the TVCT of the PSIP in the ATSC type digital broadcast,

wherein the at least one descriptor includes a stream_type field, a format_identifier field, a length_of_details field, and a stream_info_details field,

wherein the format_identifier field identifies an entity providing a stream_type value,

wherein the length_of_details field specifies a length of the stream_info_details field, and

wherein the stream_info_details field indicates information associated with the additional view video stream when the stream_type value corresponds to a specific value; and

processing the base view video stream and the additional view video stream for supporting the 3D broadcast service using the TVCT.

2. The method of claim 1, the at least one descriptor describes video components and has a value that indicates a codec type for the additional view video stream.

3. The method of claim 2, wherein the stream_type field indicates a codec type for the additional view video stream.

4. A method comprising:

encoding a base view video stream, an additional view video stream and information regarding stereoscopic characteristics for supporting a 3D broadcast service wherein a service type field indicates that a virtual channel carries a 3D broadcast service that delivers the additional view video stream and the base view video stream encoded using different codecs, and

wherein the service type field is included in a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in an Advanced Television Systems Committee (ATSC) type digital broadcast;

encoding at least one descriptor included in the TVCT of the PSIP in the ATSC type digital broadcast,

wherein the at least one descriptor includes a stream_type field, a format_identifier field, a length_of_details field, and a stream_info_details field,

wherein the format_identifier field identifies an entity providing a stream_type value,

wherein the length_of_details field specifies a length of the stream_info_details field, and

wherein the stream_info_details field indicates information associated with the additional view video stream when the stream_type value corresponds to a specific value; and

transmitting, to the receiver, the base view video stream, the additional view video stream and the TVCT such that the receiver employs said information regarding stereoscopic characteristics to support the 3D broadcast service.

5. The method of claim 4, wherein the at least one descriptor describes video components and has a value that indicates a codec type for the additional view video stream.

6. The method of claim 5, wherein the steam_type field indicates a codec type for the additional view video stream.

7. An apparatus comprising:

a receiving unit for receiving a base view video stream, an additional view video stream and information regarding stereoscopic characteristics;

an identifying unit for identifying a service type field and at least one descriptor included in a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in Advanced Television Systems Committee (ATSC) type digital broadcast

wherein the service type field indicates that a virtual channel carries a 3D broadcast service that delivers the additional view video stream and the base view video stream encoded using different codecs,

wherein the at least one descriptor includes a stream_type field, a format_identifier field, a length_of_details field, and a stream_info_details field,

wherein the format_identifier field identifies an entity providing a stream_type value,

wherein the length_of_details field specifies a length of the stream_info_details field, and

wherein the stream_info_details field indicates information associated with the additional view video stream when the stream_type value corresponds to a specific value; and

a processing unit for processing the base view video stream and the additional view video stream for supporting the 3D broadcast service using the TVCT.

8. An apparatus comprising:

an encoding unit for encoding a base view video stream, an additional view video stream and at least one descriptor for supporting a 3D broadcast service wherein a service type field indicates that a virtual channel carries a 3D broadcast service that delivers the additional view video stream and the base view video stream encoded using different codecs,

wherein the service type field is included in a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in an Advanced Television Systems Committee (ATSC) type digital broadcast,

wherein the at least one descriptor includes a stream_type field, a format_identifier field, a length_of_details field, and a stream_info_details field,

wherein the format_identifier field identifies an entity providing a stream_type value,

wherein the length_of_details field specifies a length of the stream_info ₁₃ details field, and

wherein the stream_info_details field indicates information associated with the additional view video stream when the stream_type value corresponds to a specific value; and

a transmitting unit for transmitting, to the receiver, the base view video stream, the additional view video stream and the TVCT such that the receiver employs said information regarding stereoscopic characteristics to support the 3D broadcast service.
