## Background
FIELD OF THE INVENTION
The present application relates generally to TVs with Internet videoconferencing capability.
BACKGROUND OF THE INVENTION
Internet videoconferencing has been provided to enable mobile phone users and personal computer users to communicate with each other and see as well as hear each other. Such videoconferencing is typically convenient and inexpensive. As recognized herein, it would be advantageous to leverage the audio and video capability inherent in a TV to extend Internet videoconferencing opportunities for users.
SUMMARY OF THE INVENTION
An apparatus includes a TV chassis, a TV video display on the chassis, and one or more TV audio speakers for playing audio associated with video presented on the display. The apparatus also has a TV tuner for presenting video from a selected channel on the display. A TV processor in the chassis communicates with a wide area computer network using a network interface. A microphone and a video camera are on the chassis, and an IP phone module is in the chassis for receiving signals from the microphone and video camera. The IP phone module sends the signals to one or more recipients on the wide area network using the network interface. Incoming videoconferencing signals from the wide area network are presented on the TV video display and TV audio speaker.
In example implementations the signals from the camera and microphone are multiplexed prior to being sent over the wide area network. Also, if desired the incoming videoconferencing signals from the wide area network are demultiplexed prior to display.
A switch can be provided in the chassis for selectively connecting the speaker to a TV audio baseband circuit or to the IP phone module responsive to user selection of TV mode or videoconferencing mode, respectively. The IP phone module can include an analog baseband circuit sending signals to the switch and a digital processor communicating with the analog baseband circuit and sending signals for display on the TV display. The digital processor may receive signals from the video camera while the analog baseband circuit may receive signals from the microphone.
In another aspect, a computer-implemented method includes receiving at a TV a user command to enter a videoconferencing mode, and in response to the user command, configuring a switch to disconnect a TV audio baseband circuit from a TV speaker and to connect an IP phone module to the TV speaker.
In another aspect, a system includes TV chassis, a TV supported by the chassis, and an IP phone module supported on the chassis. Information received from the IP phone module is presented on the TV.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring initially to FIG. 1, an example TV 10 in accordance with present principles can communicate videoconferencing signals in accordance with disclosure below with a wide area network 12 such as the Internet. The TV 10 can exchange video and voice signals to other components on the network 12 including, e.g., a personal computer (PC) 14, a mobile telephone 16, and another TV 18 that is configured like the TV 10.
The TV 10 may be controlled by a user manipulating a TV remote control 20 to cause TV video, video from videoconferencing, user interfaces, etc. to be presented on a TV display 22 such as but not limited to a flat panel liquid crystal display (LCD) that is supported on a TV chassis 24. Also, one or more microphones 26 and video cameras 28 (shown in FIG. 1 as being integrated in a single videoconferencing package) are mounted on the chassis 24 for purposes to be shortly disclosed.
Details of the example TV 10 can be seen in FIG. 2. A TV tuner 30 receives TV signals from a source of TV signals such as a set-top box, satellite dish, cable head end, terrestrial TV signal antenna, etc. The tuner 30 may be in the chassis 24 or it may be externally located in, e.g., a set-top box. The TV signals typically include analog and digital signals, and may be presented on the display 22 in standard definition and/or high definition.
A TV processor 32 in the chassis 24 controls the display 22 to present demanded images. The TV processor 32 may also access a TV analog baseband circuit 34 to cause one or more TV speakers 36 to play audio signals in TV programming. The TV analog baseband circuit 34 may include, e.g., digital-to-analog converter circuitry, etc.
The TV processor 32 may also communicate with a network central processing unit (CPU) 38 in the chassis 24, it being understood that the CPU 38 may be omitted and its function undertaken by the TV processor 34. In any case, the CPU 38 (or TV processor 32) communicates with the wide area network 12 shown in FIG. 1 using a network interface 40 such as but limited to a modem. In some implementations the interface 40 may be a local area network (LAN) interface of, e.g., a home network of which the TV 10 is a part, with the home network in turn communicating with the Internet.
FIG. 2 also shows that the TV processor 32 may access one or more tangible computer readable storage media such as disk-based storage or solid-state storage such as but not limited to a random access memory (RAM) device 42 and a read-only memory (ROM) device 44 such as flash memory. The logic herein may be implemented on the storage media for execution thereof by one or more processors described herein.
As shown in FIG. 2, the TV processor 32 may communicate with an Internet Protocol (IP) phone module 46 which may include a digital processor 48 such as a digital signal processor (DSP). The digital processor 48 may communicate with an analog baseband circuit 50 in the IP phone module 46 as shown. The digital processor 48 may in some embodiments be integrated with the TV processor 32 and/or CPU 38.
In any case, the digital processor 48 may be programmed to execute IP videoconferencing logic in accordance with, for instance, “Skype” principles. To this end the digital processor 48 may receive input from the video camera 28 on the TV chassis, while the analog baseband circuit 50, which can include analog to digital and digital to analog conversion circuitry, can receive input from the microphone 26 on the TV chassis. Also, the digital processor 48 of the IP phone module 46 may send signals to the TV processor 32 for display of video represented by the signals on the display 22.
As shown in FIG. 2, the analog baseband circuit 50 of the IP phone module 46 may provide audio signals to a switch 52. As can readily be appreciated in reference to FIG. 2, the switch 52, which may be controlled by, e.g., the TV processor 32, connects either the TV analog baseband circuit 34 to the speaker 36 so that audio from TV programming may be played, or the switch 52 disconnects from the circuit 34 and connects the speaker 36 to the analog baseband circuit 50 of the IP phone module 46 so that audio from videoconferencing signals may be played on the speaker.
FIG. 3 shows that a user interface may be presented on the TV display 22 permitting a person to select a TV mode or other modes, as well as an IP videoconferencing mode. The latter mode may include a sub-selection allowing a user to enter, by means of, e.g., the remote control 20 shown in FIG. 1, an address or phone number of a recipient with whom videoconferencing is to be established.
FIG. 4 shows that when a user command is received at block 54 invoking the videoconferencing mode, the logic moves to block 56 to configure the switch 52 to connect the IP phone module 46 to the TV speaker(s) 36. If not already activated, the video camera 28 on the TV chassis is activated.
Proceeding to block 58, signals received from the microphone 26 may be multiplexed by the IP phone module 46 with signals received from the video camera 28 and sent through the CPU 38 and network interface 40 over the wide area network 12 to one or more recipients as designated by the user. Also, at block 60 an incoming videconferencing signal is received from a sending videoconferencing node in the network 12 through the network interface 40 and CPU 38 and provided to the IP phone module 46, where video is demultiplexed from audio. The video is sent from the digital processor 48 to the TV processor 32 for presentation of the video on the TV display 22, while the audio is sent from the audio baseband circuit 50 of the IP phone module 46 through the switch 52 to the speaker(s) 36 for playing thereof at block 64.
Also, if desired a self-image, i.e., the image from the TV-mounted video camera 28, may be presented on the display 22, along with the image received from a sending node on the network. In this latter regard a picture-in-picture presentation may be used.
While the particular TV WITH INTERNET VIDEOCONFERENCING is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
