The verification process of partial data is executed by collating the integrity partial data as check values for a combination of partial data of a content, and the verification process of the entirety of the combination of partial data is executed by collating partial-integrity-check-value-verifying integrity check values that verify the combination of the partial integrity check values. Master keys to generate individual keys necessary for a process of such as data encryption are stored in the storage section and keys are generated as required. An illegal device list is stored in the header information of a content and referred to when data is used. Keys specific to a data processing apparatus and common keys are stored and the keys are selectively used according to the content use restriction. Plural content blocks are coupled, and at least a part of the content blocks is applied to an encryption process by an encryption key Kcon, then encryption key data that is the encryption key Kcon encrypted by an encryption key Kdis is stored in the header section. A content data is made of compression data and an expansion processing program or a combination of types of compression programs and the reproducing apparatus can determine an expansion program applicable to a compressed content.

Apparatuses and methods to enable the simultaneous viewing of multiple television channels and electronic program guide content

A Digital Home Communication Terminal (DHCT) including a plurality of tuners, each of which can select one of a plurality of transmission channels provided by a Digital Broadband Delivery System (DBDS). The multiple tuners enable the DHCT to tune to a plurality of downstream media and data transmissions, thereby allowing a subscriber to tune simultaneously to multiple channels and content transmitted in the downstream transmission via the DBDS, an advantage over conventional DHCTs. The present invention enables subscribers to receive and view multiple channels and associated content, including electronic program guide information, at will. Furthermore, using the multiple-tuner DHCT of the present invention, subscribers can view multiple television stations and program content simultaneously, without degradation to television signals or pictures.

Multicast control systems and methods for dynamic, adaptive time, bandwidth,frequency, and satellite allocations

Methods and systems to efficiently share multiple satellites and associated transponders or links among a network of uplinking earth stations are disclosed. An embodiment of this invention uses a terrestrial communications link, such as the Internet, to control access to the transponder or satellite links. Communications over this link may employ a TCP / IP protocol to connect the requesting uplinking earth stations with a centralized controller. This control system creates more efficient use of satellite resources and reduces the overall amount of time needed for transmitting data through the satellite. By reducing the overall amount of time needed for transmitting data, the control system may reduce the cost of using the satellite transponder capacity.

Video decoding and channel acquisition system

A digital video decoding system receives packetized video data representing programs conveyed on a plurality of video channels. The system includes a plurality of buffers for storing encoded video data representing images of video programs conveyed on a corresponding plurality of video channels. An individual buffer, corresponding to an individual video channel, stores sufficient encoded video data to prevent an underflow condition following switching to decode a program conveyed on the individual video channel. A processor initiates switching to decode a program conveyed on a selected one of the plurality of video channels in response to a user channel selection input. A decoder decodes encoded video data received from one of the plurality of buffers corresponding to the program conveyed on the selected video channel as determined by switching initiated by the processor. The decoder also predicts a next channel to be selected by a user based on, (a) predetermined user channel and program preference criteria, (b) predetermined user channel navigation patterns, or (c) user data entry device sensory data.

System and method for combining several EPG sources to one reliable EPG

The present invention relates to a device for acquiring electronic program guide (EPG) data from a plurality of different EPG sources (120), and combining the acquired data to a single EPG (10). At regular intervals, EPG data is acquired from different sources (120), which may include the Internet (122), digital programming broadcasters, and teletext service providers (126). Equivalent program listings (40) within the acquired EPG data are identified, and the best information is selected from the equivalent program listings (40) to be included in the combined EPG (10). The present invention is able to identify equivalent program listings (40), even if the program titles are written in different languages or when the scheduled broadcast times differ to some extent. The resulting EPG (10) is more reliable and contains more information than any of the EPGs (10) associated with the original sources (120).

Interactive content delivery methods and apparatus

Interactive content preservation and customization technology is placed at the broadcast facility to ensure reliable transmission of the interactive content to a local subsystem. An interactive content code detector detects interactive content codes in the video stream at the broadcast facility. The interactive content code detector is placed in the transmission path before the video stream is transmitted to broadcast facility hardware that may strip out, destroy, corrupt or otherwise modify the interactive content and interactive content codes. Once an interactive content code detector detects a code, an interactive broadcast server determines what action to take, and instructs an data insertion unit accordingly. The interactive content codes or interactive content may be placed in a portion of the video that is guaranteed by the broadcast facility to be transmitted, for example, the closed caption region of the vertical blanking interval.

Vertical network handovers

Establishing and controlling communication to and from a mobile terminal with multiple network interfaces that can be reached with one phone number via multiple networks. The mobile terminal simultaneously communicates with a central server over a cellular network and a WLAN to dynamically coordinate a preferred routing of a communication session with a partner node. The communication session is routed over whichever network is optimal at any given time, depending on a current location of the mobile device, current performance of each network, and other criteria. A new communication session is established through the central server to enable one number access to and from the mobile terminal. An ongoing communication session is continuously monitored to determine whether and when to perform a network handover. The mobile terminal obtains performance data regarding each network and arranges a network handover with the central server.
