A separate document explains the DTCP – DVB MPEG2 transport streams (IEC hardware errata for TSB42AA4. It is available 61883-4) upon request to DTLA licensees only. – DirecTV™ transport streams • Interfaces directly to industry standard 400-, – DV program streams (IEC 61883-2) 200-, and 100-Mbps physical layer devices, – Asynchronous streams including Texas Instruments TSB41LV0X and – Support for external processor DMA TSB41AXX family of physical layer devices • Programmable data-/space-available • Compliant with IEEE 1394-1995 and IEEE indications for flow control; almost full and 1394a–2000 standards almost empty indicators • MPEG2 time stamp-based release, as • Supports bus manager functions and described in IEC 61883-4 automatic 1394 self-ID verification • High-speed data interface (HSDI): • Interrupt driven to minimize host polling – Byte-wide or serial mode • Single 3.3-V supply – Two independent HSDI ports • Separate async acknowledge buffer – Bidirectional decreases the ack-tracking burden on host – Several control modes for a variety of • JTAG interface to support post-assembly applications scan of device I/O – Connects seamlessly to common MPEG2 • Bus holder isolation decoder chipsets • Embedded support for DTCP content • 16-bit microprocessor interface supports protection: Motorola 68000/68020-style bus – Two M6 baseline ciphers (one per HSDI • Large 8K-byte FIFO can be configured up to port) eight independent Tx or Rx FIFOs – Random number generator in hardware – SHA-1 secure hash algorithm in hardware – Authentication key cipher in hardware • Optional auto-configuration for MPEG2/DV transmit and receive functions • PID filtering and packet insertion for MPEG2 transport stream Consumer Electronics Link (ceLynx) is a high-performance 1394 link layer device designed specifically to support advanced consumer electronics applications, particularly those applications which require the transmission of Moving Picture Expert Group 2 (MPEG2) transport streams and encryption/decryption of those streams across a 1394 network. The device supports both digital video broadcasting (DVB) and DirecTV™ type MPEG2 streams using the digital transmission content protection method (DTCP) method of encryption, as well as digital video (DV) encoded streams. The ceLynx supports both the IEC 61883 standard for DVB and DV streams over 1394 and the 1394 Trade Association standard for DirecTV over 1394.
