The present invention provides a reproduction apparatus capable of automatically switching an input of a television to an output from a broadcast receiver such as an STB. A television, upon receiving a notification command notifying that output of video or audio is to start, switches its input to an output from an apparatus which has sent the notification command. An STB, upon receiving an instruction command instructing that output of video or audio should be started, sends the notification command to the television. A DVD recorder includes: a decoder that reproduces video or audio recorded in a DVD-RAM disc; a data output I / F that outputs the reproduced video or audio to the television; and a command sending and receiving I / F that sends the instruction command to the STB when the output of the reproduced video or audio ends.

An object of the invention is to permit quick control of the operating state of a source equipment side from sink equipment. A television receiver (sink equipment) 100 and an amplifier (repeater equipment) 200 are interconnected over an HDMI cable 610, and the amplifier 200 and a DVD recorder (source equipment) 300 are interconnected over an HDMI cable 620. Each of the pieces of equipment includes, in addition to an HDMI receiving unit and an HDMI transmitting unit, a high-speed data line I / F included in a bidirectional communication unit that uses predetermined lines of the HDMI cable. The bidirectional communication unit is used to transmit channel selection information, a remote control code instructing recording, “theater mode” designating information, a remote control code, or the like from the television receiver 100 to the audio amplifier 200 or DVD recorder 300. The operating state of the audio amplifier 200 or DVD recorder 300 can be quickly controlled from the television receiver 100.

A video / audio processing device (1), such as a DVD recorder, has controller (2) for controlling a state of power-on / off. The controller (2) has a first standby mode and a second standby mode having power consumption larger than that of the first standby mode in a power-off state of the video / audio processing device (1). The first standby mode is a mode for maintaining a power of the video / audio processing device (1) in the “off” state. The second standby mode is a mode for maintaining the power of the video / audio processing device (1) in an apparent “off” state. The controller (2) switches between the first standby mode and the second standby mode in conjunction with a state of power-on / off of external equipment (11) such as television.

A digital security surveillance system allows a user to store selected security surveillance feeds while the user is simultaneously watching or reviewing another feed. User control commands are accepted and sent through the system. The system parses the resulting digital stream and generates identifying information associated with at least one video segment of the digital stream. The video segments are stored on a storage device. When a security surveillance feed is requested for display, a corresponding stored digital stream is found and its video segments are extracted from the storage device and sent to a decoder that converts the digital stream into display output signals. The security surveillance feeds can be simultaneously sent to an external storage device such as a DVD recorder or VCR.

A method for preventing the copying of useable video content is disclosed. The method includes identifying the video signal content of a video signal that is suitable to be extracted, extracting video content from the video signal to transmit to a receiver, and replacing the extracted video content with marred video content in the video signal. The method further includes placing the extracted video content in a user data channel of a program stream for transmission to a receiver. In addition, the method includes transmitting portions of the video signal that contains the marred video content in a first channel of the program stream, and transmitting the extracted video content in a second channel of the program stream to the receiver. The signals transmitted in the program stream are synchronized for presentation in the display of the receiver. Only the program stream components that contain the marred video content may be recorded by a VCR or DVD recorder and the marred video is unsuitable for piracy or rebroadcast.

An internet connected mobile security system for recording at least one audio and video on a removable semiconductor storage media in a continuous record loop for evidentiary documentation purposes inside an automotive vehicle or as a wearable video recording device is described.

A video / audio processing device, such as a DVD recorder, includes a controller for controlling a state of power-on / off. The controller has a first standby mode and a second standby mode having power consumption larger than that of the first standby mode in a power-off state of the video / audio processing device. The first standby mode is a mode for maintaining a power of the video / audio processing device in the “off” state. The second standby mode is a mode for maintaining the power of the video / audio processing device in an apparent “off” state. The controller switches between the first standby mode and the second standby mode in conjunction with a state of power-on / off of external equipment such as television.

In an electronic apparatus such as a DVD recorder (1) which controls electric power supply to a main micro processor (3) and peripheral devices (10, 11, 15) with a auxiliary micro processor (4), a power control method by the auxiliary micro processor (4) can be changed. The main micro processor (3) transmits a power control data, which indicates a control method of the electric power supply, to the auxiliary micro processor (4). The auxiliary micro processor (4) controls the electric power supply by a method indicated by the power control data. Contents of the power control data is composed of sixteen bits data, and each four bits data as a unit indicate a control method of a power control terminal “REG_CTRL 1” (41) during a switching off operation of a power switch (6), a control method of the power control terminal “REG_CTRL 1” (41) during a switching off operation of the power switch (6), a control method of a power control terminal “PWSW” (43) during the switching off operation of the power switch (6), and a control method of the power control terminal “PWSW” (43) during the switching on operation of the power switch (6).

An apparatus determines whether a combination of a certificate type of a content certificate recorded on a source recording medium and a medium type of the source recording medium is a proper combination. If the combination is a proper combination, the apparatus requests a license server, which is connected to the apparatus via a network, to give approval to record content on a target recording medium. If the apparatus is a legitimate DVD recorder, the license server sends to the content recording apparatus a content certificate including on the source recording medium as the certificate type. The apparatus records the content together with the received content certificate on the target recording medium.
