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: 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 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: 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.

Abstract: A method of coding and transmitting moving pictures includes the steps of coding an extended background image, coding parameters indicative of an image area within the extended background image, coding a foreground picture that is to be composed with a background picture corresponding to the image area indicated by the parameters, coding a defocus value indicative of an extent to which the background picture should blur, and transmitting the coded extended background image, the coded parameters, the coded foreground picture, and the coded defocus value as a data stream to a decoder side. Coding and transmitting of the defocus value makes it possible to defocus the background picture at the decoder end, thereby producing a composed image of the background picture and the foreground picture having natural appearance.

Abstract: High resolution vertical and horizontal components of a high definition video signal are combined with a standard broadcast system video signal, such as the NTSC system, in which high frequency horizontal resolution components are sampled and used to modulate at least a first sub-carrier signal. The first sub-carrier is frequency interleaved onto the standard broadcast signal. Vertical high resolution components are time compressed and time division multiplexed onto top and bottom portions of the standard broadcast signal. The modified broadcast signal can be decoded by a standard receiver to display a standard resolution video image, while receivers designed to decode the modified signal can time division demultiplex the vertical high resolution components and demodulate the horizontal high resolution components, combine these components with the standard components, and generate a high definition video image.

The transmitting end of the system transmits a first television signal including a video signal, audio signals, etc., through a main transmission line, as well as a third television signal including a high definition components obtained as the difference between the second and the first television signal through an auxiliary transmission line. The receiving end of the system receives and synthesizes the first television signal transmitted through the main transmission line and the third television signal transmitted through the auxiliary transmission line to produce the second television signal.
