SCTE 26 2004

The need for interfaces between cable set top boxes and digital television (DTV) receivers isone element of a general movement to interconnect multiple audio/visual (A/V) devices on acommon bus or network. The IEEE 1394 interface has emerged as the preferred tool toaccomplish this goal. This specification contains requirements and options for an IEEE 1394digital interface between a cable TV set top box (called a Host Device in this standardbecause it "hosts" a removable security module), and a DTV receiver.IEEE 1394, which covers the physical interface, has been extended by CEA-775-A, CEA-931-B and CEA-799 which cover the command language, remote control commands, and onscreengraphics display respectively. This standard extends these to cover the needs of cableset-top boxes. In addition, the Digital Transmission Content Protection specification governscopy protection of digital content on this interface.IEEE 1394, which covers the physical interface, has been extended by CEA-775-A, CEA-931-B and CEA-799 which cover the command language, remote control commands, and onscreengraphics display respectively. This standard extends these to cover the needs of cableset-top boxes. In addition, the Digital Transmission Content Protection specification governscopy protection of digital content on this interface.The functional partitioning defined in this standard locates the MPEG signal processing intothe DTV receiver while service access and content descrambling occurs in the Host device.
