Abstract
When a transport stream is transmitted between each unit connected through an interface, if any data which is not permitted to be transmitted on a partial transport stream is transmitted, information of this section is transmitted as a private section or a user private. As a result, information of a section of an EIT can be transmitted from for example a digital satellite broadcast tuner to a personal computer and an original program schedule list can be created on the personal computer.
Claims24
An information transmitting apparatus, comprising:
- packet extracting means for extracting a packet which is permitted to be transmitted on a partial transport stream from a transport stream;
- an interface for transmitting the partial transport stream which is output through the packet extracting means to another unit;
- and
- means for outputting a packet which is not permitted to be transmitted on the partial transport stream as a packet of a private section or a packet of a user private when the packet is output through the interface.
An information transmitting method, comprising the steps of:
- extracting a packet which is permitted to be transmitted on a partial transport stream from a transport stream and outputting the extracted packet to an interface;
- and
- forming a packet which is not permitted to be transmitted on the partial transport stream as a packet of a private section or a packet of a user private when the packet is output through the interface.
An information processing apparatus, comprising:
- an interface for receiving a partial transport stream transmitted from another unit;
- packet separating means for separating packets from the partial transport stream transmitted through the interface;
- and
- analyzing means for analyzing the content of a PMT of the partial transport stream transmitted through the interface, information of each element of a transport stream being described in the PMT, and interpreting a packet of a private section as a packet which is not permitted to be transmitted on the partial transport stream when the analyzed result represents that the partial transport stream contains the private section.
An information processing method, comprising the steps of:
- receiving a partial transport stream transmitted from another unit through an interface;
- separating packets from the partial transport stream transmitted through the interface;
- and
- analyzing the content of a PMT of the partial transport stream transmitted through the interface, information of each element of a transport stream being described in the PMT, and interpreting a packet of a private section as a packet which is not permitted to be transmitted on the partial transport stream when the analyzed result represents that the partial transport stream contains the private section or a user private.
An information processing system, comprising:
- an information transmitting apparatus for extracting a packet which is permitted to be transmitted on a partial transport stream from a transport stream and outputting the extracted packet through an interface;
- and
- an information processing apparatus for receiving a partial transport stream transmitted through the interface, separating packets from the partial transport stream, and processing the packets,
- wherein when a packet which is not permitted to be transmitted on the partial transport stream is transmitted from the information transmitting apparatus to the information processing apparatus through the interface, the information transmitting apparatus is configured to transmit a packet which is not permitted to be transmitted on the partial transport stream as a packet of a private section or a packet of a user private.
