System method for local meta data insertion

A data modification system for selective insertion of local meta data into an incoming data stream, the incoming data stream having a video data component and a meta data component, the data modification system comprising:

• an incoming data terminal;
• a local data terminal;
• and
• a data modification unit coupled to the incoming data terminal and the local data terminal,
• wherein the data modification unit is adapted to selectively combine data from the incoming data terminal and the local data terminal.

A method of selectively modifying a data signal, comprising:

• receiving a data signal, the data signal comprising a first data component and a second data component;
• separating the first data component from the second data component;
• determining whether to modify the second data component;
• retrieving a third data component from a database;
• merging the third data component with the first data component;
• and
• outputting the third data component and the first data component to a distribution terminal.

A method of selectively modifying a data signal, comprising:

• receiving a data signal, the data signal comprising a first data component and a second data component;
• separating the first data component from the second data component;
• determining whether to modify the second data component;
• if modification of the second data component is not required, then forwarding the second data component;
• merging the second data component with the first data component;
• and
• outputting the second data component and the first data component to a distribution terminal;
• if modification of the second data component is required, then retrieving a third data component from a database;
• forwarding the third data component;
• merging the third data component with the first data component;
• and
• outputting the third data component and the first data component to a distribution terminal.

A data modification system for selective insertion of local meta data into a data stream, the data stream having a video data component and a meta data component, the data modification system comprising:

• a data stripper operative to separate the video data component from the meta data component;
• a data storage device for storing the local meta data;
• a processor coupled to the data storage device and the data stripper, the processor operative to selectively determine whether to replace the meta data component with the local meta data;
• and
• a data insertion unit coupled to the processor, wherein the data insertion unit is operative to replace the meta data component with the local meta data.

A data modification system for selective insertion of local meta data into a data stream, the data stream having a video data component and a meta data component, the data modification system comprising:

• means for separating the video data component from the meta data component;
• means for storing the local meta data;
• means for determining whether to replace the meta data component with the local meta data;
• and
• means for replacing the meta data component with the local meta data.

A computer-readable medium having computer-executable instructions for performing a method of selectively modifying a data signal, the method comprising:

• receiving a data signal, the data signal comprising a first data component and a second data component;
• separating the first data component from the second data component;
• determining whether to modify the second data component;
• if modification of the second data component is not required, then forwarding the second data component;
• merging the second data component with the first data component;
• and
• outputting the second data component and the first data component to a distribution terminal;
• if modification of the second data component is required, then retrieving a third data component from a database;
• forwarding the third data component;
• merging the third data component with the first data component;
• and
• outputting the third data component and the first data component to a distribution terminal.
