Method and apparatus for signaling video enhancement information (VEI) for video quality enhancement of fixed/mobile broadcasting hybrid 3DTV

An IP-based hybrid 3DTV content reception method, comprising:

• receiving multiplexed 3DTV content information;
• obtaining service layer signaling information from the received 3DTV content information;
• obtaining additional data based on the obtained service layer signaling information;
• decoding the 3DTV content information by using the obtained additional data;
• and
• playing back the decoded 3DTV content,
• wherein the 3DTV content comprises either one or both of video data and audio data,
• wherein the additional data comprises data required for either one or both of decoding and playing back the 3DTV content,
• wherein the service layer signaling information comprises information about a standard for receiving media components (User Service Bundle Description (USBD)) and/or User Service Description (USD)) of the 3DTV content, information of the media components (Media Presentation Description (MPD), and information about a session through which the media components are transmitted (Service-based Transport Session Instance Description (S-TSID)), and
• wherein the MPD comprises information corresponding to right video and information corresponding left video within a same period, and
• wherein the media components are received with reference to the MPD and the S-TSID based on information included in the USBD and/or the USD.

An IP-based hybrid 3DTV content transmission apparatus, comprising:

• an input unit configured to receive 3DTV content;
• an encoding unit configured to encode the received 3DTV content;
• an additional data generating unit configured to generate additional data;
• a service layer signaling information generating unit configured to generate service layer signaling information for obtaining the generated additional data;
• a multiplexing unit configured to generate 3DTV content information by multiplexing the encoded 3DTV content and the service layer signaling information;
• and
• a transmitting unit configured to transmit the multiplexed 3DTV content information,
• wherein the 3DTV content comprises either one or both of video data and audio data,
• wherein the additional data comprises data required for either one or both of decoding and playing back the 3DTV content,
• wherein the service layer signaling information comprises information about a standard for receiving media components (User Service Bundle Description (USBD)) and/or User Service Description (USD)) of the 3DTV content, information of the media components (Media Presentation Description (MPD), and information about a session through which the media components are transmitted (Service-based Transport Session Instance Description (S-TSID)), and
• wherein the MPD comprises information corresponding to right video and information corresponding left video within a same period, and
• wherein the media components are received with reference to the MPD and the S-TSID based on information included in the USBD and/or the USD.
