Eia

Eia or Eye was a Medieval manor in Middlesex and now part of Central London. A smaller manor called Ebury or Eybury, and the village of Eye Cross, were originally part of the manor of Eia – and derive their names from it. Both Ebury and a corruption of it, Avery, can still be found in the names of local streets and other places.

The broader area covered by the original manor of Eia included much of the present SW1 postcode area, including: Hyde Park (which dates from 1536), the grounds of Buckingham Palace (1703) and Belgravia, a country road known later as Park Lane and most parts of Mayfair, Pimlico, and Knightsbridge.

The name Eia is believed to have originated as a latinisation of the Anglo-Saxon toponym eyai, which means "island", in reference to a marsh that once dominated the area.

Middle Ages

Eia was a rural manor during the early medieval period, located on land around the underground River Tyburn (which still flows beneath the courtyard and south wing of Buckingham Palace), immediately west and north of Thorney Island, which became the site of Westminster Abbey.

CEA-708

CEA-708 is the standard for closed captioning for ATSC digital television (DTV) streams in the United States and Canada. It was developed by the Electronic Industries Alliance.

Unlike RLE DVB and DVD subtitles, CEA-708 captions are low bandwidth textual like traditional EIA-608 captions and EBU Teletext/Ceefax subtitles. However, unlike EIA-608 byte pairs, CEA-708 captions are not able to be modulated on an ATSC receiver's NTSC VBI line 21 composite output and must be pre-rendered by the receiver with the video frames, they also include more of the Latin-1 character set, and include stubs to support full UTF-32 captions, and downloadable fonts.

CEA-708 captions are injected into MPEG-2 video streams in the picture user data. The packets are in picture order, and must be rearranged just like picture frames are. This is known as the DTVCC Transport Stream. It is a fixed-bandwidth channel that has 960 bit/s allocated for backward compatible Line 21 captions, and 9,600 bit/s allocated for CEA-708 captions. The ATSC A/53 Standard contains the encoding specifics. The main form of signalling is via a PSIP caption descriptor which indicates the language of each caption and if formatted for "easy reader" (3rd grade level for language learners) in the PSIP EIT on a per event basis and optionally in the H.222 PMT only if the video always sends caption data.
