摘要： An apparatus and method for selectively encrypting portions of data sent over a network between a server and a client. The apparatus includes parsing means for separating a first portion of the data from a second portion of the data, encrypting means for encrypting only of the first portion of the data, and combining means for combining the encrypted first portion of the data with the second portion of the data, wherein the second portion of the data is not encrypted. The apparatus further includes decrypting means installed at the client for decrypting the encrypted portion of the data. The apparatus is platform independent in terms of media format and data protocol. The encryption unit encrypts data transparently to the client based on the media format. The apparatus of the invention is implemented as one of an application and a plug-in object. The method for selectively encrypting portions of data which differ from each other in at least on characteristic sent over a network between a server and a client includes parsing the data into a first and second portion, encrypting only the first portion of the data, and sending the encrypted first portion and the second portion of the data over the network to the client. The method further includes receiving data from the server, determining whether a data stream is established between the server and the client, and negotiating an encryption key with a decryption shim of the client.

摘要： A system and process for creating a Virtual Stage on a client device and presenting Enhanced Content on the Virtual Stage is provided. The Virtual Stage is preferably implemented on a Browser or similarly equipped presentation device. The Virtual Stage enables any presentation device to receive Enhanced Content from any provider regardless of the capabilities of the Browser or client device, the data format of the Enhanced Content, and/or the communications medium utilized to communicate the Enhanced Content to the Browser or client device. The Virtual Stage suitably includes an abstracted Show Object which provides a framework for presenting the Enhanced Content and an abstracted Receiver Object which provides a receiver for communicating with the Enhanced Content provider and receiving the Enhanced Content. Alternative embodiments may also include multiple abstracted Receiver Objects and/or abstracted Subscribers, which facilitates communications with subscription service provider systems, including, but not limited to, chat service systems.

摘要： A technique for streaming from a local device and a remote device involves providing a subset of data associated with a streaming application to a local device. An example of a method according to the technique includes running a streaming software player, accessing data from a local storage device necessary to stream a software application, and accessing data from a remote location necessary to stream the software application using the streaming software player. An example of a system according to the technique may include, by way of example but not limitation, a means for streaming a first subset of content associated with a streaming application from a streaming server (502), a means for streaming a second subset of content associated with the streaming application from a local source (504), and a means for periodically querying the streaming server (506), wherein the periodic querying informs the streaming server that the streaming application is running.

摘要： An apparatus of a flexible and common MPEG-2 IPMP system (Intellectual Property Management and Protection) is invented to provide flexibility and interoperability by introducing a IPMP Control Information which includes IPMP Tool List and an optional Tool Container. The IPMP Control Information is put in PSI in MPEG-2 transport stream, and a special PES packet in MPEG-2 program stream. IPMP Stream is defined to carry IPMP information that is to be sent to each individual IPMP tool instance. The concept of Tool Manager, Message Router from MPEG-4 IPMP extension is mapped into MPEG-2 terminal to form MPEG-2 IPMP framework together with introduced IPMP Control Information and IPMP Stream. As a result of this invention, the same protected MPEG-2 content is able to play back by different types of MPEG-2 IPMP terminals, and the same MPEG-2 content can be protected by using different vendors' IPMP system.

摘要： A system and method for securing intellectual property rights in distributed intellectual property. The present invention grants and polices rights in electronically distributed intellectual property. Use limitations are established by agreement by the content provider (200) and the client (100). The use limitations are reflected in time-based (112, 212), usage-based and player based component codes that are used to determine if the client (100) is entitled to use the intellectual property. The present invention further protects the intellectual property from unauthorized use by encrypting the intellectual property with a key created from some or all of the component codes. As the component codes are known to both the client (100) and the content provider (200), no key exchange is required by the present invention.

摘要： An audience rating survey apparatus acquires a user ID, which specifies a viewer/listener of a network-distributed program, a device ID which specifies a client terminal receiving the network-distributed program, and a program ID which specifies the network-distributed program, and carries out an audience rating survey of the network-distributed program based on the acquired IDs and characteristic parameters associated the acquired user ID. A network-distributed program receiving apparatus transmits a device ID which specifies itself, the user ID which specifies a viewer/listener of a network-distributed program, and the program ID which specifies the network-distributed program, to the audience rating survey apparatus every fixed time interval. This allows effective and accurate audience rating survey of, for example, an Internet-broadcasted program according to the present invention.
