A video decoder is an electrical device that transforms base-band analogue video signals into digital video and is frequently housed on a single integrated circuit chip. Commonly, video decoders enable programmable control over visual elements including hue, contrast, and saturation.
A video encoder turns unedited, uncompressed digital video into analogue video; a video decoder does the opposite. Frame grabbers and video capture equipment frequently employ video decoders.
A video decoder’s input signal is analog video that follows a predetermined format. Standard definition decoders that support SD formats like NTSC or PAL are acceptable.
Decoders for high definition accept analogue HD formats as AHD and HD-TVI. Different formats for the output digital video are possible, including 8-bit, 16-bit, 12-bit, BT.656 or BT.1120. A video decoder typically produces a clock signal in addition to the digital video output bus and other signals like: The word “Sync” denotes the start of a video frame.
Video blanking intervals are shown by blanking. Whether the current video field is even or odd is indicated by the field. Lock signifies that a valid analogue input video signal has been found and the decoder is locked to it.
The Global automotive video decoder market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Liquid crystal display controller chips with integrated video decoders that are compatible with NTSC, PAL, and SECAM video standards have been created by Oki Electric.
The small- and mid-sized LCD monitors used in automotive applications are the focus of the chips. According to Oki, samples of the ML86V8209 for mid-size monitors and the ML86V8207 for small LCD monitors are both available.
The ML86V8209 will begin shipping in large quantities in October. The ML86V8207 is anticipated to start shipping in large quantities around December.
The ML86V8207 and ML86V8209 were created for tiny QVGA-VGA LCD monitors and mid-size WVGA-XGA LCD monitors, respectively. The video decoder, scaler, on-screen display, and LCD controller are all on the same single chip in both units.
The video decoder is compliant with component video signal D2 and supports all three international video signal standards, providing synchronous stability for abnormal video signals that can appear in signal-poor conditions, including weak electric fields. Both devices adhere to ISO/TS16949 standards.
The first four-channel analogue video decoder with a MIPI-CSI2 output interface, made by Intersil Corporation, supports the newest SOCs and application processors used in automotive around view systems. The ISL79985 is the newest member of Intersil’s industry-leading video decoder family.
It saves vital board space by replacing up to nine discrete components with a single chip. For generating 360-degree around view video to detect objects around the vehicle and help drivers with backup and parking, it provides superior four-channel analogue decoding performance.
The new video decoders give drivers a clear, detailed video that improves their ability to see objects all around the vehicle. An around view monitor system, also referred to as a surround view monitor, stitches together video from four cameras to create a single top-down, birds-eye view that appears as though the camera is directly above the vehicle.
New versions of Allegro DVT’s D3x0 and E2x0 decoder and encoder IPs with extended sample sizes up to 12-bits and chroma sampling ranging from 4:2:0, 4:2:2, to 4:4:4 have been released. Allegro DVT is the top supplier of video processing silicon IPs.
The explosion in processing requirements for video codecs in emerging industries such as cloud gaming and automotive continues to strain and, at the top end, exceed the capabilities of hardware implementations that use accelerator assistance.
These requirements include increasing sample sizes from 8 bits to 10 and 12 bits and chroma sampling across a wide range of video codec formats in both encoders and decoders from 4:2:0 to 4:2:2 and 4:4:4.
Renesas has unveiled its new Automotive HD Link (AHL) technology, which enables automakers to transmit high-definition video over standard-definition video-only cables and connectors. The new RAA279971 AHL encoder and RAA279972 decoder transmit the video using a modulated analogue signal.
The encoder and decoder enable transmission rates up to 10 times lower than necessary to transmit HD signals digitally, according to the company. Due to the lower transmission rate, existing analogue video cables and connectors as well as conventional twisted pair cables can be used. AHL can initialise, programme, and monitor the camera module and has a bi-directional control channel that operates independently of the video data. AHL is noise-resistant.
