    en.wikipedia.org/wiki/1440p

    1440p video mastered from 4:3 ratio content can be displayed with 1920×1440 or higher resolution such as QXGA or 2304×1440 with scaling, windowboxing, or pillarboxing. Widescreen 16:9 aspect ratio 1440p requires 2560×1440 ( WQHD ) resolution, possible with WQXGA , 2560×1920, or higher resolution with letterboxing , scaling, or windowboxing.

    en.wikipedia.org/wiki/Adaptive_bitrate_streaming

    Adaptive streaming overview Adaptive streaming in action. Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks.. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are based almost exclusively on HTTP, [1] and are designed to work efficiently over large ...

    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.

    CBR is commonly used for videoconferences, satellite and cable broadcasting. VBR is commonly used for video CD/DVD creation and video in programs. Bit rate control is suited to video streaming. For offline storage and viewing, it is typically preferable to encode at constant quality (usually defined by quantization) rather than using bit rate ...

  7. ATSC standards - Wikipedia

    en.wikipedia.org/wiki/ATSC_standards

    The maximum bit rate value in the sequence header of the MPEG-2 video stream is 19.4 Mbit/s for broadcast television, and 38.8 Mbit/s for the "high data rate" mode (e.g., cable television). The actual MPEG-2 video bit rate will be lower, since the MPEG-2 video stream must fit inside a transport stream.

    The servers utilize Nvidia Tesla graphics cards, and can stream games at up to 4K resolution at 60 frames per second or 1440p at 120 fps. Nvidia recommended a 50 Mbit/s internet connection for the 1080/60p stream, but the service can also stream at 720p/60p for 25 Mbit/s connections, 720/30p frames per second for connections higher than 10 Mbit ...

  9. Bit rate - Wikipedia

    en.wikipedia.org/wiki/Bit_rate

    For real-time streaming multimedia, the encoding bit rate is the goodput that is required to avoid playback interruption. The term average bitrate is used in case of variable bitrate multimedia source coding schemes. In this context, the peak bit rate is the maximum number of bits required for any short-term block of compressed data. [17]
