Abstract

A sorting section in a restoration section sorts out a packet for an intended service from a transport stream received according to the control of a reception control section. The sorted out packet is provided to an output section and restored to NTSC signals. An audiovisual output section (such as a TV set) receives the signals and outputs images and voices. The reception control section acquires information on the type of contents chosen out of the transport stream through the sorting section, and further compares the contents type information with restorable contents type information recorded in a restorable contents type information recording section. Then, a determination is made whether or not the contents intended for restoration are restorable. Depending on the determination, the manner of process applied to the contents is changed. For example, the restoration of the contents is interrupted.

Claims

A digital broadcast system comprising a broadcast device and a receiving device, wherein the broadcast device broadcasts information on the location for acquiring digital information to be downloaded on the receiving device side, and also broadcasts conditions necessary for downloading the digital information as necessary for condition information,

and wherein the receiving device makes a determination whether or not the digital information can be downloaded on the basis of the necessary condition information before starting downloading the digital information.

2. A broadcast device for a digital broadcast system, wherein the device broadcasts acquisition location information on the digital information to be downloaded on the receiving device side, and also broadcasts conditions necessary for downloading the digital information as necessary condition information.

3. A receiving device for a digital broadcast system, wherein the device makes a determination whether or not the digital information coming on the air can be downloaded on the basis of the necessary condition information when starting downloading the digital information.

5. A receiving device of claim 4, wherein the receiving device is provided with a connecting section to the Internet for downloading the digital information.

6. A receiving device of claim 3, wherein the acquisition location information is the information for specifying the digital information sent to come through broadcast.

7. A reception program for controlling a computer constituting part of a receiving device, wherein a determination is made whether or not the digital information can be downloaded on the basis of the necessary condition information sent and coming through broadcast when starting downloading digital information.

8. A method of digital broadcast for broadcasting contents from a broadcasting party to a receiving party or parties, comprising:

broadcasting acquisition location information on the digital information to be downloaded on the receiving side by the broadcasting side, and also broadcasting conditions necessary for downloading the digital information as necessary condition information, and
