Abstract: A system and method for transmitting program guide information describing a second set of programs to subscribers is disclosed. In one embodiment, the method is implemented in a network broadcasting a first signal having a first set of programs and a second signal having a second set of programs. The method comprises the steps of broadcasting first program guide information describing the first set of programs to the subscribers on a first service channel on a first signal and broadcasting second program guide information describing the second set of programs to a subset of the subscribers on the first service channel on a second signal, wherein a fundamental signal characteristic of the second signal differs from the fundamental signal characteristic of the first signal.

Abstract: If there is a service provider for which basic registration has already been performed, the processing proceeds to step S15 to determine whether there is an IP broadcast service or not. If no IP broadcast service is provided, the processing proceeds to step S17 to 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 S15, the processing proceeds to step S16 to 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.

Abstract: A repository receives metadata from databases associated with different service providers. The repository converts the received metadata to a common format, such as MPEG7, and stores the converted metadata in a central database. The repository can also receive a query from a client device. The repository retrieves metadata associated with the query from the central database and provides it to the requesting client device. The repository can also convert the provided metadata to an appropriate format for the requesting device. Because the metadata is stored at a common location in a common format, content from different providers can be efficiently identified.

Abstract: EPG data regarding programs and their scheduled times are structured and/or transmitted in such a way that program and schedule records are interleaved. This scheme allows better handling by receiving devices such as embedded devices (i.e. LCD remote controls), because a more efficient reception and storage of transmitted data is possible. In particular, the receiving device can read, parse and store the downloaded EPG data on the fly as it is being received (it can start reading, parsing and storing before the complete reception of data id finished). At any time when the device would have to stop storing EPG data into persistent storage, (almost) all of the data that was stored can actually be used.
