Question: Which television color encoding system was first used in France?
Context: The Academy Color Encoding System (ACES) is a color image encoding system created by hundreds of industry professionals under the auspices of the Academy of Motion Picture Arts and Sciences.  ACES allows for a fully encompassing color accurate workflow, with "seamless interchange of high quality motion picture images regardless of source". In computing, a character encoding is used to represent a repertoire of characters by some kind of encoding system.  Depending on the abstraction level and context, corresponding code points and the resulting code space may be regarded as bit patterns, octets, natural numbers, electrical pulses, etc.  A character encoding is used in computation, data storage, and transmission of textual data.  "Character set", "character map", "codeset" and "code page" are related, but not identical, terms. 576i is a standard-definition video mode originally used for broadcast television in most countries of the world where the utility frequency for electric power distribution is 50 Hz.  Because of its close association with the color encoding system, it is often referred to as simply PAL, PAL/SECAM or SECAM when compared to its 60 Hz (typically, see PAL-M) NTSC-color-encoded counterpart, 480i.  In digital applications it is usually referred to as "576i"; in analogue contexts it is often called "625 lines", and the aspect ratio is usually 4:3 in analogue transmission and 16:9 in digital transmission. Phase Alternating Line (PAL) is a colour encoding system for analogue television used in broadcast television systems in most countries broadcasting at 625-line / 50 field (25 frame) per second (576i).  Other common colour encoding systems are NTSC and SECAM. ITU-R Recommendation BT.601, more commonly known by the abbreviations Rec.  601 or BT.601 (or its former name, CCIR 601) is a standard originally issued in 1982 by the CCIR (an organization which has since been renamed as the International Telecommunication Union – Radiocommunication sector) for encoding interlaced analog video signals in digital video form.  It includes methods of encoding 525-line 60 Hz and 625-line 50 Hz signals, both with an active region covering 720 luminance samples and 360 chrominance samples per line.  The color encoding system is known as . yEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail.  It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit Extended ASCII encoding method.  yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, compared to 33%–40% overhead for 6-bit encoding methods like uuencode and Base64.  yEnc was initially developed by Jürgen Helbing and its first release was early 2001.  By 2003 yEnc became the de facto standard encoding system for binary files on Usenet.  The name yEncode is a wordplay on ""Why encode?"" , since the idea is to only encode characters if it is absolutely required to adhere to the message format standard. The Apollo TV Camera refers to several television cameras used in the Apollo program's space missions, and on the later Skylab and Apollo-Soyuz Test Project missions, in the late 1960s and 1970s.  These cameras varied in design, with image quality improving significantly with each successive model.  Two companies made these various camera systems: RCA and Westinghouse.  Originally, these slow-scan television (SSTV) cameras, running at 10 frames-per-second (fps), produced only black-and-white pictures and first flew on the Apollo 7 mission in October 1968.  A color camera — using a field-sequential color system — flew on the Apollo 10 mission in May 1969, and every mission after that.  The Color Camera ran at the North American standard 30 fps.  The cameras all used image pickup tubes that were initially fragile, as one was irreparably damaged during the live broadcast of the Apollo 12 mission's first moonwalk.  Starting with the Apollo 15 mission, a more robust, damage-resistant camera was used on the lunar surface.  All of these cameras required signal processing back on Earth to make the frame rate and color encoding compatible with analog broadcast television standards. BinHex, originally short for "binary-to-hexadecimal", is a binary-to-text encoding system that was used on the classic Mac OS for sending binary files through e-mail.  Originally a hexadecimal encoding, subsequent versions of BinHex are more similar to uuencode, but combined both "forks" of the Mac file system together along with extended file information.  BinHexed files take up more space than the original files, but will not be corrupted by non-"8-bit clean" software. Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel.  For consumer video standards, such as High Efficiency Video Coding (H.265), the bit depth specifies the number of bits used for each color component.  When referring to a pixel, the concept can be defined as bits per pixel (bpp), which specifies the number of bits used.  When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample (bps).  Color depth is only one aspect of color representation, expressing how finely "levels" of color can be expressed (a.k.a. color precision); the other aspect is how "broad" a range of colors can be expressed (the gamut).  The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space. SECAM, also written SÉCAM (] , " Séquentiel couleur à mémoire", French for "Sequential colour with memory"), is an analogue color television system first used in France.  It was one of three major colour television standards, the others being the European PAL and North American NTSC.
Answer: SECAM
