Multimedia codec, application processor including the same, and method of operating the application processor

An application processor comprising:

• a memory configured to store an image group including at least two frames;
• a central processing unit (CPU) configured to generate a mode selection signal for determining an encoding mode in which the image group is to be encoded;
• and
• a multimedia codec configured to encode the image group according to a field mode indicated by the generated mode selection signal, the multimedia codec including,
• a reader configured to read each of the at least two frames according to the field mode to produce a top field and a bottom field, and
• an encoding component configured to encode the top field in an intra mode and encode the bottom field in an inter mode.

A device comprising:

• a memory having computer-readable instructions stored therein;
• and
• a processor configured to execute the computer-readable instructions to,
• partition at least one selected image frame selected from a plurality of image
• frames into a first group and a second group, upon receiving a mode selection signal;
• encode the first group according to an intra mode of encoding;
• and
• encode the second group according an inter mode of encoding.
