Method and apparatus for decoding/encoding a video signal

A video medium player, comprising:

• a receiving unit configured to receive a multi-view video signal, the multi-view video signal including a random access picture, the random access picture including a random access slice, the random access slice referencing only a slice corresponding to a same time and a different view of the random access picture, the multi-view video signal being transmitted as a digitally-encoded signal;
• a digital signal processing unit configured to decode a target video signal from the multi-view video signal, the digital signal processing unit configured to,
• obtain a random access flag for inter-view prediction, the random access flag indicating whether a type of picture is the random access picture,
• obtain initialization information of a reference picture list for the random access slice based on the random access flag, the initialization information representing view relationships between a plurality of views, the initialization information including view number information and view identification information,
• initialize the reference picture list for inter-view prediction, the initializing including assigning an inter-view reference index to a reference picture based on the view number information and the view identification information,
• obtain modification information for the initialized reference picture list from the multi-view video signal, the modification information representing how to change the inter-view reference index in the initialized reference picture list,
• determine an assignment modification value for changing the inter-view reference index in the initialized reference picture list according to the modification information,
• modify the initialized reference picture list for inter-view prediction, the modifying including reordering the reference picture by changing the inter-view reference index assigned to the reference picture based on the determined assignment modification value,
• determine a prediction value of a macroblock in the random access picture based on the modified reference picture list, and
• decode the macroblock using the prediction value, the initialization information being obtained from an extension area of a sequence header;
• a D/A converter configured to convert the target video signal into an analog video signal;
• and
• a display unit configured to output the analog video signal.
