Television telephone

A television telephone comprising:

• communication control means for transmitting and receiving digital encoded information of at least one of audio signals, visual signals and data signals to and from a communication network including means for multiplexing the transmitted digital encoded information and demultiplexing the received digital encoded information;
• internal audio and visual input/output means including visual input means for inputting images, display means for displaying images, and telephone control means for controlling transmission/reception functions thereof;
• external input/output terminal connection control means for enabling operation in cooperation with external equipment including at least one of audio, visual and data equipment, the external input/output terminal connection control means being mounted on a rear surface of a bottom section of the television telephone;
• and
• key operation selecting control means for controlling connection with the communication control means and for effecting selective switching between the internal audio and visual input/output means and the external input/output terminal connection control means;
• wherein the external input/output terminal connection control means includes a plurality of terminal connections which are integrated on the rear surface of the bottom section of the television telephone.

A television telephone comprising:

• image input means for inputting at least one of a moving picture image and a still picture image;
• display means for displaying image signals;
• communication control means for transmitting and receiving encoded information of audio and visual signals in a plurality of transmission modes to and from a communication network, the communication control means including means for multiplexing the encoded information and for demultiplexing the received encoded information;
• telephone control means for controlling the transmission/reception functions and including a key console unit;
• image encoding/decoding means including an image encoder circuit for encoding image input signals and an image decoder circuit for decoding received image signals;
• and
• mode control means for enabling transmitted and received images in a predetermined transmission of images of at least one of moving picture, animation, still pictures, photographs and drawings, the mode control means providing position responsive attitude control for the image input means for enabling transformation of an inputted image in point symmetry rotated by 180.degree. by controlling a direction of read out of the input image signals from a frame memory and transmission of the transformed image and being responsive to key operation of the key console unit.

A television telephone comprising:

• image input means for inputting at least one of a moving picture image and still picture image;
• display means for displaying image signals on at least one of a plurality of screens such that different images from respective ones of the screens are enabled to be viewed in at least one different portions of a viewable screen and in superposed relation on the viewable screen;
• communication control means for multiplexing encoded information of audio and visual signals in different communication modes and enabling transmission of the encoded information to a communication network and receipt of encoded information from the communication network, the communication control means enabling demultiplexing of the received encoded information;
• image encoding/decoding means including an image encoder circuit for encoding image input signals and in image decoder circuit for decoding received image signals;
• and
• image control means for enabling images inputted through the image input means to be displayed for monitoring purposes with respect to outgoing transmission images thereof on one of the screens of the display means together with images received through the image decoder circuit, the image control means enabling control of outgoing images for transmission and interruption thereof in response to key operation of the key console unit, the image control means enabling input images to be transformed in point symmetry rotated by 180.degree. and transmission of the transformed images so that the transformed images are displayed on the viewable screen of the display mean for monitoring purposes as a picture-in-picture display.
