Embodiment approach 1

[0066] (1) The structure of the transceiver system

[0067] figure 1 It is a schematic configuration diagram showing a transmission and reception system including a broadcasting station device and a recording / reproducing device according to Embodiment 1 of the present invention.

[0068] Such as figure 1 As shown, the transceiver system 1000 of this embodiment includes a broadcasting station device 100 , a recording and reproducing device 200 , a video output device 300 and an audio output device 400 .

[0069] The broadcasting station device 100 transmits a television broadcast signal (hereinafter abbreviated as a TV broadcast signal) compressed and encoded by the MPEG (Motion Picture Experts Group)-2 standard. The recording and reproducing apparatus 200 receives a TV broadcast signal transmitted from the broadcast station apparatus 100, and extracts a video signal and an audio signal from the TV broadcast signal. Details of the broadcast station device 100 and the recordi...

Embodiment approach 2

[0171] (1) The structure of the transceiver system

[0172] The transceiver system of Embodiment 2 and figure 1 The transceiver system 1000 differs in the following respects.

[0173] Figure 11 It is a block diagram showing a schematic configuration of the recording / reproducing apparatus 200 according to the second embodiment. Such as Figure 11 As shown, the recording / reproducing device 200 of this embodiment further includes a duplicate scene detection unit 212 . In addition, in this embodiment, it is assumed that the recording / reproducing unit 204 has a data reading function of TS packets and PES packets.

[0174] Also, in this embodiment, the data manipulation described in Embodiment 1 is not performed on the TS. Therefore, a normal TS is input to the receiving unit 201 . Also, the recording / reproducing unit 204 performs processing different from the sorting processing described in the first embodiment.

[0175] (2) Processing of the recording and reproducing devic...

Abstract

A broadcast station device includes a video edition unit and a TS encoder. A video edition unit generates a video signal by editing a video of a TV program and a video of a CM. When a substantially identical scene is arranged before and after the CM in the video signal generated by the video edition, a TS encoder operates predetermined data on a TS packet containing the information on the identical scene (duplicate scene) after the CM. According to the data, a recording / reproduction device selects a TS packet containing the information on the duplicate scene. During a time shift reproduction,the TS packet containing the information on the duplicate scene is not decoded.

Description

technical field [0001] The present invention relates to a broadcasting station device for transmitting TV broadcasting signals and a recording and reproducing device for recording and reproducing the TV broadcasting signals. Background technique [0002] When the TV (hereinafter abbreviated as TV) broadcast cannot be viewed in real time, the viewer records the TV broadcast to DVD (Digital Versatile Disc) or HD (hard disk) and other recording media. [0003] When the recording medium is reproduced, the viewer can watch only the desired scene by using the fast forward function of the recording and reproducing device or the like. As a result, viewers can efficiently watch TV broadcasts. [0004] In addition, conventionally, recording and reproducing apparatuses having a function of automatically fast-forwarding a commercial (hereinafter abbreviated as CM) (hereinafter referred to as a CM skip function) have been developed. According to such a recording / reproducing apparatus,...
