Abstract

A wireless camera 11 includes a main body unit 16, encoding/transmission unit 17, and a battery unit 18. The encoding/transmission unit 17 includes a encoding/modulation unit 23 for performing MPEG 2 encoding and OFDM modulation, frequency converter 27, high-frequency amplifier 28, and a transmission antenna 19. The main body unit 16, encoding/transmission unit 17, and battery unit 18 are unitedly configured.

Claims

1. A wireless camera, comprising:

pick up means;

encoding means for encoding video signals picked up by the pick up means to generate transmission data of a predetermined encoding system;

modulation means for orthogonal frequency-division-multiplex modulating the transmission data encoded by the encoding means;

transmission means for frequency-converting modulated signals generated by the modulation means into signals of a radio frequency band, and radiating frequency-converted signals via an antenna;

battery means; and

first housing means for housing the encoding means and the transmission means wherein the first housing means comprises;

first connecting means for removably connecting a first portion of the pick up means to a first portion of the first housing means;

second connecting means for removably connecting a second portion of the pick up means to a second portion of the first housing means;

third connecting means for removably connecting the first housing to the battery means; and

fourth connecting means for removably connecting the first housing to a transmission antenna;

wherein the pick up means, the encoding means, the modulation means, and the transmission means are housed in a second housing.

2. The wireless camera according to claim 1, wherein the first connecting means comprises one or more protruding members adapted to interface with one or more corresponding recessed portions of the pick up means.

3. The wireless camera according to claim 1, wherein the second connecting means comprises a substantially wedged-shaped portion adapted to interface with the pick up means in a substantially interference relationship.
