The ASI output of a DVB Integrated Receiver/Decoder (IRD). It carries the entire MPEG transport stream being received from a DVB satellite feed entering the RF input (far left side in picture). Asynchronous Serial Interface, or ASI, is a method of carrying an MPEG Transport Stream over 75-ohm copper coaxial cable or optical fiber. [1]
MPEG-2 is used in Digital Video Broadcast and DVDs. The MPEG transport stream, TS, and MPEG program stream, PS, are container formats.. MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". [1]
World's first real-time MPEG-1 video encoder chipset; Contained 1.2M transistors per chip; Up to eight chips were used for 'full screen' (720×480) resolution; Enabled the launch of the DirecTV program by RCA/Thomson; Enabled the development of mass content for VideoCDs and digital karaoke in the Far East; CL9100 MPEG-2 decoder 1994 Real-time ...
The cable tuner, QAM demodulator, and MPEG decoder are part of the host equipment. The card performs any conditional access and decryption functions, and provides a MPEG-2 transport stream to the host. The card also receives messages sent over the out-of-band signaling channel by the cable company's headend servers and forwards them to the host.
Multiple MPEG programs are combined then sent to a transmitting antenna. An ATSC receiver then decodes the TS and displays it.. The Program and System Information Protocol (PSIP) is the MPEG (Moving Picture Experts Group, a video and audio industry group) and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended ...
H.262 [2] or MPEG-2 Part 2 (formally known as ITU-T Recommendation H.262 and ISO/IEC 13818-2, [3] also known as MPEG-2 Video) is a video coding format standardised and jointly maintained by ITU-T Study Group 16 Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG), and developed with the involvement of many companies.
Series2 TiVo systems are based on MIPS processors connected to MPEG-2 encoder/decoder chips and high-capacity IDE/ATA hard drives. Series2 units had drives of 40–250 GB in size. Although not supported by TiVo or equipment manufacturers, larger drives can be added.
DirecTV transmits programming with encryption to mitigate signal piracy. The receiver (also known as an IRD, or "integrated receiver-decoder") utilizes ISO/IEC 7816 smart cards which tell the receiver how to decrypt the programming for viewing. In a continuing effort to combat piracy, an access card generation is created approximately every two ...
