Benefits of technology

[0010]The present invention has been made in view of the above circumstances, and an object of the invention is therefore to enable acquisition of program information in a short time by increasing the transmission amount of data of program information when the transmission amounts of video data and audio data can be decreased.
[0011]Another object of the invention is to allow an information receiving apparatus to recognize, in a short time, the transmission statuses of schedule EPG data that indicate program broadcast schedules of the transmission side.

Problems solved by technology

Further, since schedule EPG data indicating program broadcast schedules has long re-transmission cycles and there is no data indicating their transmission statuses, an information receiving apparatus takes long time to judge the state of the transmission side when the transmission of the schedule EPG data is suspended due to the equipment trouble on the transmission side.

Embodiment Construction

[0032]FIG. 3 is a block diagram showing the configuration of an information transmitting apparatus according to an embodiment of the invention. The information processing apparatus 1 outputs a transport stream TS based on a plurality of video signals and audio signals that are input externally. An MPEG video encoder 11-1 generates a video elementary stream based on a video signal that is input externally and outputs it to a multiplexer 13-1. An MPEG video encoder 11-2 generates a video elementary stream based on a video signal that is input externally and outputs it to a multiplexer 13-2.

[0033]An MPEG audio encoder 12-1 generates an audio elementary stream based on an audio signal that is input externally and outputs it to the multiplexer 13-1. An MPEG audio encoder 12-2 generates an audio elementary stream based on an audio signal that is input externally and outputs it to the multiplexer 13-2.

[0034]The multiplexer 13-1 multiplexes a video elementary stream supplied from the MPEG v...

Abstract

MPEG video encoders and MPEG audio encoders encode video signals and audio signals, respectively. An SI / EPG data generator generates program information. A transport stream multiplexer multiplexes the program information with video data and audio data. A system controller controls the data output rates of the encoding operations and the multiplexing ratio.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an information transmitting apparatus and method, an information receiving apparatus and method, a provider, and a broadcasting system. In particular, the invention relates to an information transmitting apparatus and method, an information receiving apparatus and method, a provider, and a broadcasting system in which the transmission amount of data of program information can be increased when the transmission amounts of video data and audio data can be decreased. The invention also relates to an information transmitting apparatus and method, an information receiving apparatus and method, a provider, and a broadcasting system in which the information receiving apparatus can recognize, in a short time, the transmission statuses of schedule EPG data that indicate program broadcast schedules of the transmission side.[0003]2. Description of the Related Art[0004]In digital broadcasting system...
