A program search device is configured to extract a program using search condition attribute information of the program. The device includes a unit storing information concerning the storage condition, and a display control to control display of a list that includes both search condition information and a program list. The display control highlights a search condition as most recently stored in the storing unit.

Content notifying device, notifying method, and program

A television set () includes a determination section () and a notification section (). The determination section () determines, as program information to be notified to a user, a plurality of pieces of program information each of which matches a search condition set beforehand, from among a plurality of pieces of program information. The notification section () notifies the user of the television set () of the plurality of pieces of program information thus determined by the determination section ().

If there is a service provider for which basic registration has already been performed, the processing proceeds to step Sto determine whether there is an IP broadcast service or not. If no IP broadcast service is provided, the processing proceeds to step Sto determine whether there is another service provider for which the basic registration has already been performed. If no other service provider for which the basic registration has already been performed is found in this determination, a transition is made to a portal site of the service provider for which the basic registration has already been performed. If it is determined that an IP broadcast service is provided in step S, the processing proceeds to step Sto perform a caution display. In the caution display, a display is made to prompt acquisition of channel information. In the case of acquiring channel information, an indication informing the user is displayed so that the channel information can be acquired at this phase. Thereby, when IP broadcasting is selected, the receiver determines whether there is a broadcast viewable with the receiver and changes a screen after transition, thus enabling the user to perform an operation without any confusion.

Digital broadcast receiver and reception method

Upon start of processing, a digital broadcast receiver can acquire a CDN configuration information file (XML) after newly connected to a CDN by a user's operation. Next, the digital broadcast receiver acquires a PF configuration information file written in the CDN configuration information. The digital broadcast receiver judges whether there is an IP broadcast or not. If there is an IP broadcast, the digital broadcast receiver connects to a multicast address described in the PF configuration information file (XML), and acquires information on all channels in the PF from a SI dedicated stream (all station SI including no video or audio) (channel scan). The URL of a SNTP is described in the CDN configuration information file. Time information is acquired through the SNTP at the same time as (or at a timing near the timing of, such as immediately before or immediately after) the channel scan. The above processing enables easy time acquisition which is a problem peculiar to an IPTV with which viewing of an IP broadcast is possible.

Digital broadcast receiver and digital broadcast reception method

There is provided an IP broadcast receiver apparatus capable of, even when the input of a stream is delayed, determining whether a stream is to be inputted later and displaying a picture when a stream is inputted. When the content providing side makes a request to set a streamstatus attribute to 'play' in a display using BML, the IP broadcast receiver apparatus determines whether channel information has been acquired from an IP broadcast server. The IP broadcast receiver apparatus sets the streamstatus attribute to 'play' if channel information has been acquired from the IP broadcast server and sets the streamstatus attribute to &#x201c;stop&#x201d; if channel information has not been acquired from the IP broadcast server.
