The data broadcast specification for data carousels supports data broadcast services that require the periodic transmission of data modules through DVB compliant broadcast networks. The modules are of known sizes and may be updated, added to, or removed from the data carousel in time. Modules can be clustered into a group of modules if required by the service. Likewise, groups can in turn be clustered into SuperGroups. Data broadcast according to the data carousel specification is transmitted in a DSM-CC data carousel which is defined in MPEG-2 DSM-CC. This specification defines additional structures and descriptors to be used in DV compliant networks. The method is such that no explicit references are made to PIDs and timing parameters enabling preparation of the content off-line.
Industry:Entertainment
Application of an algorithm to reduce the bit rate of a digital signal, or the bandwidth of an analog signal while preserving as much as possible of the information usually with the objective of meeting the constraints in subsequent portions of the system.
Industry:Entertainment
Analysis or display of signals in which only their digital value is considered and not their precise voltage or timing. A logic state analyzer displays information in the data domain.
Industry:Entertainment
An item of data as represented before encoding and after decoding.
Industry:Entertainment
Essence that is distinguished as different from video or audio essence. Digital data that may stand alone or may be associated with video or audio essence or metadata.
Industry:Entertainment
A method for dividing a bit stream into two separate bit streams for error resilience purposes. The two bit streams have to be recombined before decoding.
Industry:Entertainment
The data broadcast specification profile for data pipes supports data broadcast services that require a simple, asynchronous, end-toend delivery of data through DVB compliant broadcast networks. Data broadcast according to the data pipe specification is carried directly in the payloads of MPEG-2 TS packets.
Industry:Entertainment
The speed at which digital information is transmitted, typically expressed in hertz (Hz), bits/second (b/s), or bytes/sec (B/s). The higher the data rate of your video capture, the lower the compression and the higher the video quality. The higher the data rate, the faster your hard drives must be. Also called throughput.
Industry:Entertainment
The process of reducing the number of recorded or transmitted digital data samples through the exclusion of redundant or unessential samples. Also referred to as Data Compression.
Industry:Entertainment
These packets are part of the 1.00 Mbit/s overhead in video applications. These packets contain navigation information for searching and seamless playback of the Video Object Unit (VOBU). The most important field in this packet is the sector address.
This shows where the first reference frame of the video object begins.
Advanced angle change and presentation timing are included to assist seamless playback. They are removed before entering the MPEG systems buffer, also known as the System Target Decoder (STD).
