Video quality of service management and constrained fidelity constant bit rate video encoding systems and methods
A constrained variable rate coding technique limits the number of bits used in an encoding process. A quality setting indicates a maximum level of quality to be used in the encoding process which limits the number of bits used in the encoding process. A bandwidth reclamation factor which indicates an amount of bandwidth to conserve may also be used with the quality setting. The constrained variable rate coding technique using a lower quality encoding process for less complex video data and a higher quality encoding technique for higher quality video data.
1. An apparatus for managing quality of video services:
a management interface which is configured to produce at least one bandwidth reclamation factor for one or more video coding units;
a management network which is configured to convey data from the management interface to the one or more video coding units;
the one or more video coding units which are constant bit rate and responsive to a bandwidth reclamation factor; and
a data network which is configured to convey at least video data from the one or more video coding units and a video user,
wherein the management interface receives one or more video channel quality parameters which indicate at least one of an operator's desired video quality for each channel, or an individual subscriber's desired video quality for each channel, and wherein a bandwidth reclamation factor indicates an amount of bandwidth to be made available on average, and
wherein the one or more video coding units are configured to produce adaptive bit rate (ABR) chunks and associated metadata.
