Embodiment Construction

[0042] Embodiments of the present invention will be described below.

[0043] FIG. 3 shows the configuration of the digital broadcast receiving device 100 . The receiving device 100 includes a CPU (Central Processing Unit) 101 as a controller for controlling the operations of various parts of the device, and a remote control signal receiving unit 102 that receives a remote control signal RM from a remote control transmitter 210 . The user can perform various operations on the receiving device 100 using the remote control transmitter 210 . The CPU 101 and the remote control signal receiving unit 102 are connected to the bus 103 . An operation signal corresponding to the received remote control signal RM output from the remote control signal receiving unit 102 is supplied to the CPU 101 via the bus 103 .

[0044] Furthermore, the reception device 100 has a front end (F / E) 104 that performs down-conversion processing, broadcast signal selection processing, and the like on the b...

Abstract

The invention relates to a content data transmission apparatus, content data processing apparatus and the like suitable for digital broadcast transmission apparatus, reception apparatus and the like. A move_pause descriptor is included in a PMT multiplexed in a transport stream TS. A CPU 101 controls move processing and pause processing on the content data based on the description of the move_pause descriptor. The move_pause descriptor contains such information as moveability of the content data, a number of times of allowable moves, pauseability of the content data, a number of times of allowable pauses, and a time limit of pausing. In the move, when copying of a stream TS stored in an HDD 106 is not prohibited, it can be moved to a storage device 240 without changing copy generation information of the content data. In the pause, when copying of the stream TS is prohibited, the stream TS is stored in the HDD 106 without being output to an output device (e.g. monitor 230), and subsequently retrieved therefrom to output it to the output device. The invention enables protection for copyright of the content provider when the content data is moved or paused.

Description

technical field [0001] The present invention relates to a transmitting device and a transmitting method for transmitting content data such as video and audio transport streams, and a processing device and processing method for processing the content data thereof. [0002] More specifically, the present invention relates to a content data transmission device such as the following, which at least includes an indication indicating whether, when copying is not prohibited, it is possible to move content data from a recording device to another recording device without changing the copy generation information. The additional information of the move information in the move process of the device is combined with the content data and sent, so that the move process for the content data can be restricted according to the move information combined in the content data, and the content provider can realize Transfer of copyright protection. [0003] In addition, the present invention relates...
