Abstract: Provided are a signal processing device and a program which is capable of switching from a broadcast program to VOD, and during viewing of the VOD, if an emergency alert is superimposed upon a broadcast wave, displays the emergency alert under certain conditions, and which additionally is capable of displaying only VOD when viewing a recording. This signal processing device (4), on the basis of a signal from a remote control (R), upon switching to VOD content on the basis of an AIT in order to display the content upon a display (21), in response to detection of a boot flag for an emergency alert broadcast for a TMCC carrier included in a broadcast wave of a broadcasting station before the switching, displays the emergency alert broadcast included in the broadcast wave upon the display (21).

Abstract: The objective of the present invention is to provide an integrated broadcasting communications receiver capable of reliably receiving application activation information and reducing the costs for receiving the application activation information. The integrated broadcasting communications receiver includes an application activation information extracting unit that extracts application activation information from an event information table contained in a transport stream of broadcast data transmitted by a broadcast transmitting apparatus, an application obtaining unit that obtains an application with reference to an address of an application server described in the application activation information, an application executing unit, and an application controlling unit that controls an activation state of the application in accordance with a control code described in the application activation information.

Abstract: Provided is a broadcast communication cooperative reception device which controls the activation of applications associated with sub-channels. A broadcast communication cooperative reception device (400) is provided with: an APL activation information extraction means (402a) for extracting application activation information; an APL activation information storage means (407) for storing application activation information in association with a sub-channel of an event information channel; an activation control means (409a) for activating an application, the activation of said application being instructed by a control code of the application activation information corresponding to the sub-channel; and a termination control means (409b) for causing the application to terminate, the termination of said application being instructed by the control code.

Abstract: The integrated broadcasting communications receiver (400) receives from an application, by the resource request receiving unit (416a), a normal resource request and a resource request with time reservation for specifying a usage start time, then determines, by the resource allocating unit (416b), for the normal resource request and the resource request with time reservation received by the resource request receiving unit (416a) whether or not the resource requests can be granted, and then allocates one or more resources. When the resource request with time reservation is not granted at the initial usage start time, the resource allocating unit (416b) delays the usage start time and determines at the delayed usage start time again whether or not the resource request can be granted.
