  • Patent number: 11979594
    Abstract: Provided is a transmitting device including a hierarchical classification section that classifies image data of each picture constituting moving image data into a plurality of layers, an image coding section that codes the classified image data of each layer, and generates a video stream holding the coded image data of each layer, and a transmitting section that transmits a container in a prescribed format that includes the generated video stream. The image coding section performs coding so that a referenced picture belongs to a layer of referencing image data and/or a layer lower than the layer of the referencing image data.

  • Patent number: 8438599
    Abstract: Guide information is provided relating to playing/viewing of content retrieved through various modalities such as television broadcasting and a computer network. A unified program list is created that comprehensively handles program content. For a self-recorded program, program metadata retrieved during a recording operation is additionally registered. For a network program, a network program list is periodically retrieved from a service site, modified and recorded. To play the content, a guide screen is created and supplied based on a unified program list. When a self-recorded program is selected, the program is read and played from an HDD. When a network program is selected, the program is played in a streaming manner via the Internet.

  • Patent number: 8418203
    Abstract: By describing electrical program guide information in a language such as XML and then multiplexing the electrical program guide information to a broadcast signal for transmission, advertisements, images and sounds can be easily entered and various program guides can be realized. For manufacturers of receiving devices, it suffices to develop only the software for receiving, decoding and displaying received XML data. There is no need to develop the software for displaying the EPG for each type of receiving device. Thus, the number of development steps can be reduced.

  • Patent number: 8374195
    Abstract: The protection of data against illicit transfer with respect to specific data can be ensured. An integrated receiver decoder determines whether or not ATRAC (Adaptive Transform Acoustic Coding) data requiring authentication is contained in selected piece-of-music data in accordance with determination data added into transmitted data. When ATRAC data requiring authentication is contained, the integrated receiver decoder performs an authentication process between it and a storage which is a transfer destination of the ATRAC data, and performs downloading of the ATRAC data after confirming that the storage is a valid apparatus to which the downloading may be performed.

  • Patent number: 7840644
    Abstract: In a system for providing information to a user through the use of a BS broadcast, information items can be displayed in an optimum order and the information can be deleted from or stored in a storage device in the optimum order. Attribute information showing information categories may be designated. When the information stored in the storage device is viewed, the number of times the information is viewed is counted for each category of the information by using the attribute information indicating the information category. A user access tendency is determined from the count value of the accessed category, and an access priority is determined from the user access tendency. Attribute information showing the priority of the information may also be designated. In this case, the access priority is determined from the attribute information indicating the information priority.

  • Patent number: 7454780
    Abstract: This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.
