- 1-46. Cancelled
- 47. A reception terminal communicably linked to an electronic program information preparing and transmitting apparatus via a plurality of transport streams,
wherein the electronic program information preparing and transmitting apparatus for preparing electronic program information concerning the plurality of channel services and a transmitter adapted to transmit the prepared electronic program information toward the reception terminal via the plurality of transport streams, comprising: electronic program information preparing means for preparing:
(i): distributing information indicating which channel service should be distributed to which transport stream and (ii): both of a first type of electronic program information concerning each of the plurality of channel services and a second type of electronic program information concerning each of the plurality of channel services, wherein the first type of electronic program information is described with a first degree of detail and the second type of electronic program information is described with a second degree of detail that is different in description of program information from the first degree of detail; electronic program information distributing means for distributing, on the basis of the distributing information, to each transport stream:
(1): the first type of electronic program information concerning each channel service to a first transport stream assigned to the channel service, and (ii): the second type of electronic program information concerning each channel service to the remaining one or more transport streams other than the first transport stream; and a transmitter adapted to transmit, to the reception terminal, the transport streams to which the electronic program information has been distributed, wherein the reception terminal comprises: a receiver adapted to receive the electronic program information concerning the plurality of channel services from the electronic program information preparing and transmitting apparatus through the transport streams; and displaying means for displaying both of the first and second types of electronic program information in a form in which all the first and second types of electronic program information concerning all the plurality of channel services are listed together; wherein the first type of electronic program information concerns a user's desired channel service isolated from the plurality of channel services.
- 48. The reception terminal according to claim 47, wherein the first degree of detail is higher in the description of program information than the second degree of detail.
- 49. The reception terminal according to claim 48, wherein the first type of electronic program information is longer in a period of time of description than the second type of electronic information whereby the first degree of detail is higher than the second degree of detail.
- 50. The reception terminal according to claim 48, wherein the first type of electronic program information is larger in a described amount of electronic program information than the second type of electronic information, whereby the first degree of detail is higher than the second degree of detail.
- 51. The reception terminal according to claim 47, wherein the electronic program information preparing means of the electronic program information preparing and transmitting apparatus is configured to produce distributing information indicating correspondences between the transport streams and the channel services broadcast by each of a plurality of broadcast service stations.
- 52. The reception terminal according to claim 51, wherein the distribution information provides for correspondence between plural transport streams and plural channel services, respectively, broadcast by the same broadcast service station, and
wherein the electronic program information distributing means is configured to distribute, to each of the plural transport streams assigned to the same broadcast service station, the first type of electronic program information concerning each of the plural channel services broadcast by the same broadcast service station.
- 53. The reception terminal according to claim 52, wherein the first degree of detail has a greater amount of description of program information, than the second degree of detail.
- 54. The reception terminal according to claim 53, wherein the first type of electronic program information is longer in a period of time of description than the second type of electronic information, whereby the first degree of detail is greater than the second degree of detail.
- 55. The reception terminal according to claim 53, wherein the first type of electronic program information has a larger described amount of electronic program information than the second type of electronic information, whereby the first degree of detail is greater than the second degree of detail.
