DIGITAL VIDEO RECEIVER UTILIZING METADATA, PORTABLE INFORMATION DEVICE, PROGRAM RELATED INFORMATION UTILIZING SYSTEM, AND METHOD OF CONTROLLING THESE

PROBLEM TO BE SOLVED: To quickly acquire a necessary and sufficient amount of metadata wastelessly with simple facilities. SOLUTION: When a predetermined operation is conducted at a terminal, a request transmitter 40 transmits a request indicative of hold or output of the current metadata extracted by a receiver R, to the receiver R via a near field communication means or via another information transmission means. A metadata output means 35 including a code generator 32 outputs metadata held by a metadata holding means 30 to a terminal T by converting the metadata to a two-dimensional barcode such as QR code (registered) and displaying it on a display screen via a program output means 15.
