Sony secure transmission of digital content. While surfing the sony site for info on my new sony digital video camera I came across this interesting piece. Maybe some of the techies can evaluate this. iLink does not appear to address metering but it does seem to provide a hardware secure environment for transmission of digital content. bob spears SONY ANNOUNCES THE FIRST i.LINK? (IEEE1394) LSI INCORPORATING 5C DIGITAL CONTENT PROTECTION TECHNOLOGY SAN JOSE, Calif. Jan. 6, 1999 - Sony Electronics announced today the launch of i.LINK (IEEE1394) LSI "CXD3200 family" that provides robust protection for digital content transmitted between digital electronic products, such as digital set-top boxes, DVD players, digital video recorders and digital television sets. CXD3201R(link layer LSI) and CXD1945R(physical layer LSI) chip samples are now available for evaluation and early product development efforts. The sample price of a CXD3201R chip is $50, and the sample price of a CXD1945R chip is $10. Sony plans to begin volume production of the i.LINK LSI that integrates the link layer and a three-port physical layer in one device with U.S. product launch slated for this spring. "The launch of CXD3200 family marks the first LSI incorporating 5C digital content protection which we believe offers the most practical solution for safe and reliable transmission of digital content," said Jodie Hughes, senior vice president of the Semiconductor Business Division at Sony Electronics. "The introduction of Sony's new i.LINK LSI allows consumer electronics hardware manufacturers to introduce digital content protection equipped products this year." The digital content protection method employed by Sony's new LSI is based on the Digital Transmission Content Protection Method (DTCP), jointly developed by five companies, including Hitachi, Ltd., Intel Corp., Matsushita Electric Industrial Co., Ltd., Sony Corp., and Toshiba Corp. Technical information about the "5C" (for five-company) DTCP method and licensing information can be found in the Internet at dtcp.com . The newly developed LSI supports the secure, two-way transmission of digital content across the i.LINK (IEEE1394) interface at speeds of up to 200Mbps. Designed for use in a wide variety of digital electronics products, the chip reduces the load on the systems? microprocessor by internally encrypting and decrypting AV content, such as MPEG data streams. This allows for robust, high speed protection of high bandwidth content such as video and animation. The CXD3200 family supports simultaneous transmission of two separate isochronous streams over a single connection. That allows the recording and playback at the same time, or it can simultaneously transmit two separate isochronous signals. The chip supports the Program ID (PID) parser and packet insertion functions used by electronic program guides (EPGs) and other interactive broadcast and network applications. These functions are used to isolate both individual TV programs and additional service information from the data stream. The LSI also supports many modes of data interfaces for isochronous communications including dedicated MPEG-2 transport stream input and output interface, IEC958 audio stream input and output interface, and an output interface to D/A converter. The LSI contains multiple FIFO?s to support high bandwidth demand and can accommodate up to 512 bytes of asynchronous communication. The CXD3201R, packaged in a 144pin LQFP (plastic), uses a 3.3 volt power supply, ideally suited for low power applications.
