Abstract

A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.

Claims

1. A method for utilizing digital broadcast content comprising:

receiving the digital broadcast content by a mobile terminal;

recording selected digital broadcast content from the received digital broadcast content;

editing, through the mobile terminal, the selected digital broadcast content to produce mobile terminal edited digital broadcast content, based on digital rights management data; and

activating a recording process on the mobile terminal by;

receiving a broadcast content record command through a mobile terminal user interface; and

generating a recording notification message that includes;

a recording notification message identifier, user identification data, begin recording data and a day or time stamp.

2. The method of claim 1 wherein receiving the digital broadcast content includes receiving the digital broadcast content through a digital broadcast receiver of the mobile terminal and wherein the method includes wirelessly sending the recording notification message to a network element using a wireless transmitter of the mobile terminal.

3. The method of claim 2 further comprising receiving, by the network element, the recording notification message and an end of recording notification message from the mobile terminal;

generating, based on the recording notification message and the end of recording notification message, billing information corresponding to an amount of digital broadcast content recorded by the mobile terminal.

4. The method of claim 3 wherein generating the billing information is based on determining how many additional mobile terminals received the mobile terminal edited digital broadcast content from the mobile terminal.

5. The method of claim 3 further comprising sending the digital rights management data by the network element to the mobile terminal in response to receiving the recording notification message.

6. A digital broadcast content recording apparatus comprising:

a transcoder operative to convert digital broadcast content to a lower bandwidth coded information stream for communication to a mobile terminal;

a copyright processor operatively coupled to detect whether the digital broadcast content can be copied based on digital rights management data;

a broadcast content editor operatively coupled to the copyright processor and responsive to editing commands received from the mobile terminal, to edit pre-converted digital broadcast content to produce edited digital broadcast content based on the digital rights management data; and

synchronization logic, operatively coupled to the broadcast content editor, and operative to synchronize editing of the pre-converted digital broadcast content based on the editing commands from the mobile terminal.

7. The apparatus of claim 6 further comprising:

a broadcast receiver, operatively coupled to the transcoder, and operative to receive the digital broadcast content; and

memory operatively coupled to the broadcast content editor that stores the edited pre-converted digital broadcast content for transmission to another device.

8. The apparatus of claim 6 further comprising control logic operative to generate billing information corresponding to an amount of digital broadcast content recorded in response to a recording notification command received from the mobile terminal.

9. A method for utilizing digital broadcast content comprising:

converting received digital broadcast content to a lower bandwidth coded information stream for communication to a mobile terminal;

sending the lower bandwidth coded information stream to the mobile terminal;

receiving editing commands from the mobile terminal; and

synchronizing editing of the received digital broadcast content based on the editing commands from the mobile terminal to edit pre-converted digital broadcast content to produce higher bandwidth edited digital broadcast content based on digital rights management data.

10. The method of claim 9 further comprising:

receiving the lower bandwidth coded information stream, by the mobile terminal;

generating, through a user interface of the mobile terminal, the editing commands based on the received lower bandwidth coded information stream; and

sending the editing commands, by the mobile terminal, to a network element to effect remote control of editing of higher bandwidth received digital broadcast content by the network element based on viewing of the lower bandwidth coded information stream from the mobile terminal.

11. A wireless mobile terminal comprising:

a broadcast receiver operative to receive digital broadcast content over a broadcast channel;

a wireless transmitter operative to transmit information;

a controller,operatively coupled to the broadcast receiver and to the wireless transmitter;

a copyright processor operatively coupled to the controller to receive the digital broadcast content;

a broadcast content editor operatively coupled to the copyright processor and operative to edit selected digital broadcast content to produce mobile terminal edited digital broadcast content based on digital rights management data;

memory operatively coupled to the broadcast content editor and to the controller;

a user interface operative to receive a broadcast content record command and operatively coupled to the controller; and

wherein the controller generates a recording notification message that includes at least;

a recording notification message identifier, user identification data, begin recording data and a day or time stamp and generates an end of recording notification message.

12. A method for utilizing digital broadcast content comprising:

wirelessly sending at least one of digital broadcast content capture commands and editing commands by a mobile terminal;

receiving the at least one of digital broadcast content capture commands and editing commands sent by the mobile terminal;

capturing or editing, by a network element, received digital broadcast content based on the received content capture commands or editing commands;

converting the received digital broadcast content to a lower bandwidth coded information stream for communication to the mobile terminal;

sending the lower bandwidth coded information stream to the mobile terminal; and

wherein

wirelessly sending the at least one of digital broadcast content capture commands and editing commands is based on the lower bandwidth coded information stream.
