Abstract

The present invention relates to a transmitting apparatus and transmitting method as well as a receiving apparatus and receiving method configured to be able to recognize only channel selection information for digital broadcasting that is viewable at the receiving end.

A communication unit 79 transmits a viewing license and channel selection information to a receiving apparatus that receives digital broadcasting. The viewing license includes a license expiration date given as terms of use for content of digital broadcasting, and a scramble key for unlocking scrambling applied to content. The channel selection information is information related to digital broadcasting channel selection. The present invention can be applied to a server that communicates with a receiving terminal which receives digital broadcasting, for example.

Claims

1. A transmitting apparatus, comprising:

acquiring means for acquiring a license that includes terms of use for content of digital broadcasting used at a receiving apparatus that receives the digital broadcasting; and

transmitting means for transmitting the license that includes terms of use for content of digital broadcasting to the receiving apparatus that receives the digital broadcasting;

wherein

the license includes channel selection information for receiving the content of the digital broadcasting.

2. The transmitting apparatus according to claim 1, wherein

the license includes a decryption key for unlocking encryption applied to the content.

3. The transmitting apparatus according to claim 1, characterized in that

the content of the digital broadcasting is transmitted by community broadcasting.

4. The transmitting apparatus according to claim 1, wherein

the transmitting means transmits the license to the receiving apparatus via a network.

5. A transmitting method, including steps wherein a transmitting apparatus

acquires a license that includes terms of use for content of digital broadcasting used at a receiving apparatus that receives the digital broadcasting, and

transmits the license that includes terms of use for content of digital broadcasting to the receiving apparatus that receives the digital broadcasting,

wherein

the license includes channel selection information for receiving the content of the digital broadcasting.

6. A receiving apparatus, comprising:

license receiving means for receiving, via a network, a license that includes terms of use and channel selection information for content of digital broadcasting;

content receiving means for selecting the channel of the digital broadcasting on the basis of the channel selection information included in the license, and receiving the content; and

playback means for playing back the content of the digital broadcasting on the basis of the license.

7. The receiving apparatus according to claim 6, wherein

the license includes a decryption key for unlocking encryption applied to the content.

8. The receiving apparatus according to claim 7, further comprising:

decrypting means for decrypting encrypted content using the decryption key.

9. The receiving apparatus according to claim 6, characterized in that

the received content of the digital broadcasting is transmitted by community broadcasting.

10. The receiving apparatus according to claim 6, characterized in that

the license receiving means receives the license via a network.

11. A receiving method, including steps wherein a receiving apparatus

receives, via a network, a license that includes terms of use and channel selection information for content of digital broadcasting,

selects the channel of the digital broadcasting on the basis of the channel selection information included in the license, and receives the content, and

plays back the content of the digital broadcasting on the basis of the license.
