Abstract
Packetized program information used in video processing and storage medium formats includes multiple text strings. A decoder decodes packetized program information containing multiple text strings associated with a program. The decoder determines from a first indicator in the packetized program information a type of coding and compression employed in encoding a first text string. The decoder decodes the first text string with a decoding function selected in accordance with the determined type of coding and assembles decoded text string elements to form an output text string.
Claims20
Apparatus for decoding packetized program information containing multiple text strings associated with a program, comprising:
- means for determining from a first indicator in said packetized program information a type of coding and compression employed in encoding a first text string;
- means for decoding said first text string with a decoding function selected in accordance with said determined type of coding;
- and
- means for assembling decoded text string elements to form an output text string.
A storage medium containing MPEG compatible digital data representing video information comprising:
- a packetized video program;
- and
- information containing,
- (a) multiple text strings associated with said packetized video program,
- (b) a first indicator for indicating a type of coding employed in encoding a first text string, said first indicator being suitable for use in selecting a decompression function to be used in decoding said first text string;
- and
- (c) information suitable for use in assembling decoded text string elements to form an output text string.
Apparatus for generating program specific information suitable for inclusion in packetized video program information, said program specific information including multiple text strings associated with a video program, said apparatus comprising:
- means for forming text string decoding information for decoding multiple text strings, said decoding information including,
- (a) a first indicator indicating a type of compression employed in encoding a first text string for selecting a decoding function to be used in decoding said first text string;
- and
- (b) information suitable for assembling decoded text string elements to form a decoded text string;
- and
- means for incorporating said text string decoding information into program specific information for output.
A method for decoding packetized video program information containing multiple text strings associated with a program, comprising the steps of:
- determining from a first indicator in said packetized video program information a type of coding employed in encoding a first text string;
- decompressing said first text string with a decompression function selected in accordance with said determined type of compression;
- and
- assembling decoded text string elements to form an output text string.
A method for generating program specific information suitable for inclusion in packetized video program information, said program specific information including multiple text strings associated with a video program, said method comprising the steps of:
- forming text string decoding information for decoding multiple text strings, said information including,
- (a) a first indicator indicating a type of compression employed in encoding a first text string for selecting a decompression function to be used in decoding said first text string;
- and
- (b) information suitable for use in assembling decoded text string elements to form a decoded text string;
- and
- incorporating said text string decoding information into program specific information for output.
