## Abstract

An electronic apparatus includes a receptacle having a plurality of pins for connecting a plug of a transmission cable and a transmission cable determination section adapted to apply a predetermined voltage to a predetermined one of the pins of the receptacle to determine a category of the transmission cable.

## Claims

### Claim 1

A transmission cable, comprising:
two plugs each having a plurality of pins disposed on an inner side of a shield shell with an insulating member interposed therebetween for connecting to a receptacle of an electronic apparatus;
two resistors, each of the two resistors resistor being directly connected between a predetermined respective one of the pins and a respective shield shell of said plug,
wherein each of the predetermined pins which are connected to the two resistors are also connected to one another.

### Claim 2 (depends on 1)

The transmission cable according to claim 1, wherein
a resistance value of each resistor is a value corresponding to a category of said transmission cable.
