This ITU-T recommendation defines coding of speech at 16 kbit/s based on code-excited linear prediction (CELP). The delay of about 2 ms in G.728 is lower than other typical implementations of this type of coding.
G.728 audio is used in H.320 videoconferencing.
Industry:Software
A mode in which the video raster is scanned over the face of the CRT by the electron gun, tracing alternate scan lines in successive refresh cycles. The quality of interlaced video is lower than sequentially scanned (non-interlaced) video because only half of the lines are refreshed at a time and interlaced video scans at a lower rate than non-interlaced video allowing for the manufacture of less expensive video monitors. NTSC video (standard TV) uses interlace video. A display system where the even scan lines are refreshed in one vertical cycle (field), and the odd scan lines are refreshed in another vertical cycle. The advantage is that the bandwidth is roughly half that required for a non-interlaced system of the same resolution. This results in less costly hardware. It also may make it possible to display a resolution that would otherwise be impossible on given hardware, The disadvantage of an interlaced system is flicker, especially when displaying objects that are only a single scan line high.
Industry:Software
The basic transmission channel of an ATV channel using an augmentation channel.
Industry:Software
The process of drawing a frame by alternately drawing the rows of each field, creating the illusion that the image is being redrawn twice as often as it actually is. See Field.
Industry:Software
A range of allowed picture parameters defined by the MPEG-2 video coding specification with maximum resolution equivalent to ITU-R Recommendation 601.
Industry:Software
The RS-protected transport packets are reshuffled byte by byte by the 12-channel interleaver. Due to this reshuffle, what were neighbouring bytes are now separated by at least one protected transport packet: i.e., at least 204 bytes apart from each other. The purpose of this is the burst error control for defective data blocks.
Industry:Software
A subset of the syntax of the MPEG-2 video coding specification that is expected to be supported over a large range of applications.
Industry:Software
A technique used with error correction that breaks up burst errors into many smaller errors.
Industry:Software
Widely used shorthand notation for a specific quality and resolution of MPEG: Main Profile (4:2:0 quality), High Level (HD resolution).
Industry:Software
A connector that has raised edges, pins, or other protruding parts that you plug into a female connector. An example of a male connector is an electrical plug that you plug into a wall outlet.
