User interface and processing system for digital video, audio and ancillary data
View Patent ↗A video decoder User interface system supports decoding, recording and other applications including the addition of new decoder features and the conversion of data formats between read-only and recordable formats, for example. The system involves generating a menu from stored data representative of a pre-formed menu containing a menu icon permitting User selection of data format conversion of packetized data from a read-only data format to a different recordable data format. The system generates navigation parameters that are compatible with the recordable data format and incorporates them in output data in response to User selection of the menu icon. In another feature, the pre-formed menu also contains an inactive menu icon that is activated by associating and linking an active command with the inactive menu icon.
1. A method for providing a user interface for processing a video program including encoded digital packetized data representative of a sequence of individual images, comprising:
generating a user menu from pre-formed menu elements comprising an inactive menu icon, wherein video manager information and program chain information corresponds to said user menu;
rendering graphically a menu icon upon the association of an active user command to said inactive menu icon; and
updating said video manager information and program chain information with data indicating the association of said active user command to said inactive menu icon.
2. The method of claim 1 , wherein
said video manager information and program chain information is recorded on a re-recordable medium.
3. The method of claim 2 , wherein
said video manager information and program chain information represents at least one menu icon and corresponding active command that was pre-existing before said updating step; and
said video manager information and program chain information pre-exists on said re-recordable medium wherein said information indicates said at least one menu icon and corresponding active command that was pre-selected and is replaced on said re-recorded medium with information indicating said association of said active user command to said inactive menu icon.
4. The method of claim 1 , wherein
said inactive menu icon is invisible and is rendered visible in said graphically rendering step.
5. An apparatus for providing a user interface for processing a video program including encoded digital packetized data representative of a sequence of individual images, comprising:
a means for generating a user menu from pre-formed menu elements comprising an inactive menu icon, wherein video manager information and program chain information corresponds to said user menu;
a means for graphically rendering a menu icon upon the association of an active user command to said inactive menu icon; and
a means for updating said video manager information and program chain information with data indicating the association of said active user command to said inactive menu icon.
6. The apparatus of claim 5 , wherein
said video manager information and program chain information is recorded on a re-recordable medium.
7. The apparatus of claim 6 , wherein
said video manager information and program chain information represents at least one menu icon and corresponding active command that was pre-existing before updating by said means for updating; and
said video manager information and program chain information pre-exists on said re-recordable medium wherein said information indicates said at least one menu icon and corresponding active command that was pre-selected and is replaced on said re-recorded medium with information indicating said association of said active user command to said inactive menu icon.
8. The apparatus of claim 5 , wherein
said inactive menu icon is invisible and is rendered visible by said means for graphically rendering a menu icon.
9. An apparatus for providing a user interface for processing a video program including encoded digital packetized data representative of a sequence of individual images, comprising:
a menu generator that generates a user menu from pre-formed menu elements comprising an inactive menu icon, wherein video manager information and program chain information corresponds to said user menu;
a graphics renderer that graphically renders a menu icon upon the association of an active user command to said inactive menu icon; and
an updater that updates said video manager information and program chain information with data indicating the association of said active user command to said inactive menu icon.
10. The apparatus of claim 9 , wherein
said video manager information and program chain information is recorded on a re-recordable medium.
11. The apparatus of claim 10 , wherein
said video manager information and program chain information represents at least one menu icon and corresponding active command that was pre-existing before updating by said updater; and
said video manager information and program chain information pre-exists on said re-recordable medium wherein said information indicates said at least one menu icon and corresponding active command that was pre-selected and is replaced on said re-recorded medium with information indicating said association of said active user command to said inactive menu icon.
12. The apparatus of claim 9 , wherein
said inactive menu icon is invisible and is rendered visible by said graphics renderer.
