Abstract: The present invention provides for a method for converting a video data file into a format usable by a portable video player that comprises, in a single selection on the video data file, ripping and deCSS the video data file if necessary 8, converting the video data file 10 into the format usable by the portable video player to produce a playable file, the file has a name prefix and a name suffix, renaming the name suffix to be compatible with the portable video player, and making the playable file accessible to the portable video player 12. Converting the video data file specifies the video format, the video aspect ratios the maximum video bit rate, the maximum video frame rate, the audio encoder type and the maximum audio bit rate. In a particular embodiment 36 the video format is H.264, the video aspect ratio is 320×240, maximum video bit rate is 768 kbps, the maximum video frame rate is 30 fps, the audio encoder is ACC-LC and the maximum audio bit rate is 160 kbps.

Abstract: Reducing the file size for a video data file by obtaining the video data file in a data line format (4) that has multiple data lines which contain pixel information, organizing the data lines into groups, and merging the pixel information amongst the data lines in each of the groups to produce groups of merged single data lines (6). The merged single data lines are repetitive and are used to produce a reduced video data file. A video player plays the reduced video data file and updates (8) a data line by using the merged data line of each of the groups.

Abstract: A device and a method for removably installing a transmitter 6 into a portable communication device 4 that involves device that has a port for a removably attached transmitter. A new transmitter is installed and selected for. Alternately, the original transmitter may be used in a new portable communication device.

Abstract: An audio visual communication system and method that has a first user and at least one additional user. A computerized network, a first computerized device for the first user and a second computerized device for the second user. The computerized devices have a display, an input control, access to the computerized network and an audio and visual capturing apparatus. A link between the first device and the second device is established over the computerized network, and audio and visual data is transferred between the devices. The data is compressed before being sent and decompressed after being received. Both the data being sent by the devices and data being received by the devices are displayed on the devices. The first user sets a frame rate of the visual data and an overall data rate of the audio and visual data that the first device is sending over the computerized network.

Abstract: The present invention provides for an audio visual communication system that comprises a communications network, a first central processing unit housed within a body, a display and an audio and visual capturing apparatus. A link between a first central processing unit and a second central processing unit is established over the communications network and audio and visual data is transferred. The data is compressed before being sent and decompressed after being received. Both the data being sent by the central processing unit and data being received by the central processing unit is displayed to the user.

Abstract: A multimedia distribution system that comprises a digital carrier with a unique identifier thereon (4), a performance in digital media (2) and de-compression software (8). The unique identifier is encoded in at least one of the de-compression software (10) and the digital medium and the performance is copied to the digital carrier (3). The digital carrier transfers the performance to a machine along with the de-compression software (9). The de-compression software attempts to verify the unique identifier on the digital carrier (12), and if the de-compression software verifies the unique identifier, the performance is played on the machine (14).
