Abstract

In general, a digital video player and recorder (camcorder) is described that may include a Wi-Fi module, a soft phone client application, and an antenna. An antenna connects to the Wi-Fi module to transmit and receive a compressed digital video signal wirelessly as radio frequency waves at transmitted frequencies and data rates established by the Wi-Fi standard to and from a Wi-Fi enabled router base station and then to a server of an instant messaging communication system that uses the Internet and then to another computing device capable of displaying video files. The soft phone client application resident on the digital video player and recorder has code to facilitate making phone calls over the internet by breaking audio and video data into packets, formatting the packets into compliance with the instant messaging communication system, encoding the server'"'"'s IP address into the packets, and specially marking the packets that contain video data.

a Wi-Fi module to encode audio only data files as well as video data files into packets to be transmitted at frequencies and data rates established by a Wi-Fi standard, where the data in the transmitted packets is compressed;

an antenna connected to the Wi-Fi module to transmit and receive the packets wirelessly as radio frequency waves at transmitted frequencies and data rates established by the Wi-Fi standard to and from a Wi-Fi enabled router base station and then to a server of an instant messaging communication system that uses the Internet and then onto another target computing device capable of playing and displaying video files;

a soft phone client application resident on the digital video player and recorder that has code to facilitate making phone calls over the Internet by breaking audio only and video data into the packets, formatting the packets into compliance with a protocol of the instant messaging communication system, encoding the server'"'"'s IP address into the packets, associating the target computing device'"'"'s phone number or network address with the packets, and specially marking the packets that contain video data;

a processing unit to execute the camera'"'"'s application software that operates the digital video camera as well as the instructions of the soft phone client application;

a digital viewfinder having a display to allow a user to see the images in a target area to be captured in the digital video footage and then recorded in the internal memory;

a video compression component to compress a size of the captured video footage;

a Direct Current power source to power the digital viewfinder, the processing unit, the internal memory, the Wi-Fi module, the digital video image sensor, and the digital audio sensor; and

a camera body to house the digital video image sensor;

the processing unit, the internal memory, the Wi-Fi module; and

the digital audio sensor.

2. The digital camcorder of claim 1, wherein two or more displays are part of the digital video camera and a first display attaches a front side of the camera body and a second display attaches a back side of the camera body.

3. The digital camcorder of claim 1, wherein the Wi-Fi module also wirelessly receives video signals encoded in the instant messaging communication system'"'"'s transmission format, and an instant messaging system conversion application changes the video signals in the instant messaging communication system'"'"'s format to another format displayable on the display and audible from a speaker in the video camera.

4. The digital camcorder of claim 1, wherein the camera'"'"'s application software may reserve portions of the internal memory for recording a video file, which can then be later retrieved and sent to another computing device.

5. The digital camcorder of claim 1, wherein the camera'"'"'s application software may also reserve a portion of the internal/removable non-volatile memory to record a video or audio phone call conducted through the camera while the phone call is occurring and store the phone call data file for later recall.

6. The digital camcorder of claim 1, wherein the Wi-Fi module to encode audio and video data files is a wireless module that transmits according to an IEEE 802.11 standard and transmits packet in a VoIP format.

7. The digital camcorder of claim 1, wherein the compression logic further compresses the video data as it is placed into packets prior to wireless transmission by the Wi-Fi module so the further compressed video data can travel more quickly to the target computing device.

8. The digital camcorder of claim 1, wherein the Wi-Fi application of the Wi-Fi module has code to detect and connect to any router or Wi-Fi connection within the range of the video camera'"'"'s broadcast area, when the user turns on the Wi-Fi feature of the digital camera.

9. The digital camcorder of claim 1, wherein the Wi-Fi module also has a transmitter that has multiple levels of power boost to extend the transmission range of the Wi-Fi signal from the antenna.

10. The digital camcorder of claim 1, wherein the digital view finder'"'"'s display is rotatably attached to the camera body to allow the digital viewfinder'"'"'s display to rotate, and the display is configured for two way viewing between caller and callee showing both what video images are being transmitted from the Wi-Fi module and what video images are being received by the Wi-Fi module.

11. The digital camcorder of claim 10, wherein the camera application software has code to allow the user to choose to see on the display all three of the following options, what video file the Wi-Fi module is broadcasting, the video file being received by the Wi-Fi module or both the received and transmitted video files concurrently on the same display.

12. The digital camcorder of claim 1, wherein the lens for capturing video is rotatably attached to the camera body and the display and the lens are on the same side of camera

13. The digital camcorder of claim 1, wherein two or more separate lenses for capturing video connect to the camera body, where a first lens connects physically in the front of the camera and another mounts in the back for focusing on the user viewing the display.

14. The digital camcorder of claim 1, further comprising a TV out module and jacks in the camera body to convert the video signals into a TV format and whatever video file or video files are being presented on the display will also be projected onto a connected TV set.

15. The digital camcorder of claim 1, wherein the camera'"'"'s application software has code to allow received text messages from another communication device to be overlaid and displayed on the display even during a phone call in which the Wi-Fi module is receiving video data files being displayed on the display.

16. The digital camcorder of claim 1, wherein the camera'"'"'s application software has code and the Wi-Fi module is configured when turned on to continuously feed recorded video files in the internal memory wirelessly to any detected and communications connected Wi-Fi router base station within the broadcast range and then the video files are routed to a server on the Internet for more permanent storage, and after all of a video file or a portion a video file broken up into discreet segments is confirmed successfully transferred to the server on the Internet, then the camera'"'"'s application software has code to erase all or that segment of the video file from the video camera'"'"'s internal memory.
