Abstract

A multiplexing apparatus for multiplexing a first stream and a second stream for output includes a first input unit supplied with a first material; a second input unit supplied with a second material; a first selecting unit for selecting one of the first material and the second material as material of the first stream; a second selecting unit for selecting the other of the first material and the second material as material of the second stream; a control unit for controlling the first selecting unit and the second selecting unit so as to select the second material in place of the first material as the material of the first stream and so as to select the first material as the material of the second stream during a predetermined period of time; and a multiplexing unit for multiplexing the first stream and the second stream.

Claims18

Dependent claims

A multiplexing apparatus for multiplexing a first stream and a second stream for output, said multiplexing apparatus comprising:

a first selecting unit having a first input operable to receive first content and a second input operable to receive second content, and being operable to select a given one of the first content and the second content as the first stream and to output another given one of the first content and the second content to a second selecting unit;
said second selecting unit having a first input operable to receive the output from said first selecting unit and having a second input operable to receive the second content, and being operable to select between the output received from said first selecting unit and the second content received from said second input of said second selecting unit as the second stream;
a control unit operable to control said first selecting unit to select the first content as the first stream until a first predetermined time, to select the second content as the first stream and to output the first content to said second selecting unit during an interval between the first predetermined time and a second predetermined time, and to again select the first content as the first stream after the second predetermined time;
said control unit being further operable to control said second selecting unit to select the second content as the second stream until the first predetermined time, to select the first content received from said first selecting unit as the second stream during the interval between the first predetermined time and the second predetermined time, and to again select the second content as the second stream after the second predetermined time;
and
a multiplexing unit operable to multiplex the first stream and the second stream for delivery over a transmission channel.

3 more elements

An image output apparatus, comprising:

a front end unit operable to receive a signal that includes a first stream and a second stream;
a selecting unit operable to select one of the first stream and the second stream;
a control unit operable to control said selecting unit to select the first stream until a first predetermined time, to select the second stream during an interval between the first predetermined time and a second predetermined time, and to again select the first stream after the second predetermined time, the first stream being first content until the first predetermined time and after the second predetermined time and being second content during the interval between the first predetermined time and the second predetermined time, the second stream being the first content during the interval between the first predetermined time and the second predetermined time;
and
an output unit operable to output the selected one of the first stream and the second stream whereby the first content is continuously outputted.

2 more elements

An image output method, comprising:

receiving a signal that includes a first stream and a second stream;
selecting a given one of the first stream and the second stream;
controlling said selecting step to select the first stream until a first predetermined time, to select the second stream during an interval between the first predetermined time and a second predetermined time, and to again select the first stream after the second predetermined time, the first stream being first content until the first predetermined time and after the second predetermined time and being second content during the interval between the first predetermined time and the second predetermined time, the second stream being the first content during the interval between the first predetermined time and the second predetermined time;
and
outputting the selected one of the first stream and the second stream whereby the first content is continuously outputted.
