Abstract
The contents authoring unit classifies a program information into any one of the “information effective only in viewing”, the information effective only in recording/reproducing, and the “information effective in viewing and recording/reproducing”, and describes it on the basis of the classification. The contents controller of the receiving unit processes to classify the program information contained in the service information. The VCR control unit controls a VCR. Thereby, the invention utilizes the program information.
Claims16
A digital broadcasting information transmitting unit comprising:
- generation means for generating a video data based on a program;
- determination means for determining a service information relating to the video data generated by the generation means;
- classification means for classifying the service information determined by the determination means into a first program information that is relevant to viewing the program and a second program information that is relevant to recording and reproducing the program;
- description means for tabulating the first program information into schedule and present/following event information tables, and tabulating the second program information into the present/following event information;
- and
- encoding means for encoding the video data and the schedule and present/following event information tables into a video stream corresponding to a broadcast channel.
A method of transmitting a digital broadcasting information, comprising the steps of:
- a generating step of generating a video data based on a program;
- a determination step for determining a service information relating to the video data generated by the generation step;
- a classification step of classifying the service information determined by the determination step into a first program information that is relevant to viewing the program and a second program information that is relevant to recording and reproducing the program;
- a description step of tabulating the first program information into schedule and present/following event information tables, and tabulating the second program information into the present/following event information table;
- and
- an encoding step of encoding the video data and the schedule and present/following event information tables into a video stream corresponding to a broadcast channel.
An information receiving unit for receiving an encoded video data that includes a program and a corresponding service information classified on the basis of relevance to viewing, recording, and reproducing said program, the information receiving unit comprising:
- decoding means for decoding the encoded video data;
- extracting means for extracting the service information from the video data decoded by the decoding means;
- receiving means for receiving commands from a user of said information receiving unit;
- and
- processing means for processing the video data into said program in accordance with the user's commands and the extracted service information.
A method of receiving an encoded video data that includes a program and a corresponding service information classified on the basis of relevance to viewing, recording, and reproducing said program, comprising the steps of:
- a decoding step of decoding the encoded video data;
- an extracting step of extracting the service information from the video data decoded by the decoding step;
- a receiving step of receiving commands from a user of said information receiving unit;
- and
- a processing step of processing the video data into said program in accordance with the user's commands and the extracted service information.
