A reproducing device includes a reproducer that reproduces a content, a communicator that establishes a direct wireless connection to an information terminal, and a controller. The controller determines whether the information terminal is a previously permitted information terminal or not when the communicator receives a content reproduction request from the information terminal through wireless connection. The controller performs first control to power on the reproducer, and issues an instruction to perform the content reproduction to the reproducer, when it is determined that the information terminal is the previously permitted information terminal, and when the reproducer is powered off. The controller does not perform the first control when it is determined that the information terminal is not the previously permitted information terminal.

Reproduction device and output device

A control device including: an input unit which accepts input of a reproduction mode; a content reproduction device determination unit which determines whether content is to be reproduced by a content reproduction device or by the control device, in accordance with the reproduction mode; and a display unit which displays reproduced content, wherein the content reproduction device determination unit transmits a content reproduction instruction to the content reproduction device if the content reproduction device determination unit determines that the content is to be reproduced by the content reproduction device, and the content reproduction device determination unit causes the display unit to display the content acquired from a server if the content reproduction device determination unit determines that the content is to be reproduced by the control device.

Control device, control system, and control method

A content playback device includes a communication unit which communicates with a control device; a display unit which displays content; an input unit which accepts input; and a content playback authorization determination unit which determines whether to switch from content being displayed to acquired content, wherein the content playback authorization determination unit determines whether it is necessary to acquire an instruction as to whether to switch from the content being displayed to the acquired content, and when the content playback authorization determination unit acquires an authorization instruction or determines that it is not necessary to acquire the instruction, the content playback authorization determination unit switches from the content being displayed to the acquired content, and when the content playback authorization determination unit acquires a rejection instruction, the content playback authorization determination unit causes the display unit to continue display of the content being displayed.

Control of display for switching between currently displaying content and new content

A transmission control device generates, based on a content stream acquired from an external source, auxiliary information necessary for at least one of recording and playback of a content in the content stream and transmits a transmission target stream to an external device. The transmission target stream includes a first stream portion based on the content stream and a second stream portion based on the generated auxiliary information.

Transmission controller, reception controller, transmission control method, reception control method and transmission control program

The content reproduction device receives, from a server, information for indicating the location of content reproduction control information that is required for acquiring the content reproduction control information, and acquires the content reproduction control information from the server. Then, the content reproduction device extracts AV data and clip identification information for specifying clip information for managing the AV data. Then, the content reproduction device converts a predetermined part of the information for indicating the location of the content reproduction control information by applying the clip identification information and a predetermined conversion rule, generates information for indicating the location of the clip information and the AV data, and acquires the clip information and the AV data from the server.

Content reproduction system, content reproduction method, content reproduction device, and server

A transmitting side communications device transmits a Delete Payload of an IPsec SA using an ISAKMP SA that satisfies a transmission condition, and more preferably using all ISAKMP SAs that exist between communications devices. The receiving side communications device accepts a Delete Payload by an ISAKMP SA that satisfies a reception condition, and preferably any ISAKMP SA that exists between the communications devices. As long as there exists an IPsec SA that was established using the ISAKMP SA, it remains possible to maintain an ISAKMP SA, without completely deleting it, and to transmit and receive a Delete Payload by that ISAKMP SA.

Communications device and communications program

An encryption information determination section in a communication device negotiates an encryption algorithm to be used for encrypted communications with an encryption information determination section in a network camera, which is a communication counterpart. At this time, the encryption algorithm to be selected is varied depending on the CPU load of the communication device. That is, if the CPU utilization rate is high, a low-load encryption algorithm is selected, and if the CPU utilization rate is low, a high-load encryption algorithm is selected. A encryption/decryption processing section performs code processing using the encryption algorithm selected by the encryption information determination section.
