Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
Transrating is a process similar to transcoding in which files are coded to a lower bitrate without changing video formats; [3] this can include sample rate conversion, but may use an identical sampling rate with higher compression.
HD (1080i) data rate ~ 100 Mbit/s: 8– 20 Mbit/s ~1– 50 Mbit/s >1.5 Gbit/s >1.1 Gbit/s >1.5 Gbit/s >1.5 Gbit/s / up to 14:1 [12] >1.5 Gbit/s: Essence packing Discrete audio, metadata and video frame packets, single connection Modified RTSP/RTP type connections Discrete audio, metadata and video frame packets, single connection Packetized raw ...
For example, uncompressed songs in CD format have a data rate of 16 bits/channel x 2 channels x 44.1 kHz ≅ 1.4 Mbit/s, whereas AAC files on an iPod are typically compressed to 128 kbit/s, yielding a compression ratio of 10.9, for a data-rate saving of 0.91, or 91%.
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
Previous HDMI versions use three data channels (each operating at up to 6.0 Gbit/s in HDMI 2.0, or up to 3.4 Gbit/s in HDMI 1.4), with an additional channel for the TMDS clock signal, which runs at a fraction of the data channel speed (one tenth the speed, or up to 340 MHz, for signaling rates up to 3.4 Gbit/s; one fortieth the speed, or up to ...
This conversion is done using large numbers of delay cells and is appropriate for analog video. It may also be performed using a specialized scan converter vacuum tube. [1] In this case polar coordinates (angle and distance) data from a source such as a radar receiver, so that it can be displayed on a raster scan (TV type) display.
The data rate for the M-JPEG files created can be up to 74 Mbit/s. In August 2016, Canon announced that the 5D Mark IV camera would record 4K video in M-JPEG, [6] with a data rate of approximately 500 Mbit/s. [7] A video that was recorded on a Canon 5D mark IV in DCI 4K using motion jpeg
