Title: Adaptive rate control for digital video compression
Inventor: LEE CHONG U
IPC: H04N7/30
Filed: 1997-10-09
Abstract: A system and method for adaptively controlling the encoded data rate in a data compression system. The system and method sets up alternative encoded bit streams for each segment of data and selects the alternative that would produce the bit rate closest to a predetermined target bit rate for transmission. Each segment of the video input is quantized by a set of quantizers (20a-20c) to produce a plurality of quantized segments. Each quantized segment is variable rate encoded by a variable-length encoder (22a-22c) based on a quantization index to produce an alternative encoded bit stream. A set of rate measurers (24a-24c) measure the data rate that would be required to transmit each alternative encoded bit stream, and comparator (30) compares the measured rates with a predetermined target bit rate. The encoded bit stream having a rate closest to the target bit rate is provided to a rate buffer (34) in preparation for transmission. Having processed one segment of data, the system and method then updates its parameters for processing the next segment of data. A target bit rate update element (38) determines an updated target bit rate based on the rate buffer status. In addition, a quantization index update element (36) generates new quantization indices for processing the next segment of data.

Title: Technique for effectively communicating multiple digital representations of a signal
Inventor: LOU HUI-LING
IPC: H04J1/00
Filed: 2000-03-13
Abstract: In a communications system implementing, e.g., an in- band on channel AM (IBOC-AM) (also known as "hybrid IBOC- AM") scheme, multiple bit streams are used to represent an audio signal to be transmitted over one or more frequency bands including, e.g., parts of an AM frequency band for radio broadcast. These bit streams contain various and/or equivalent amounts of audio information. In an illustrative embodiment, at least one of the bit streams is a core bit stream containing core audio information. The remaining bit streams are enhancement bit streams containing enhancement audio information. The core bit stream is necessary for recovering the audio signal with minimal acceptable quality. Such quality is enhanced when the core bit stream, together with one or more of the enhancement bit streams, is used to recover the audio signal. In accordance with the invention, the AM frequency band is divided. into subbands. Each of the core and enhancement bit streams is assigned to a respective one of the subbands for transmission. The assignment is conducive to an effective treatment of interference affecting the IBOC-AM system. Other embodiments may include, e.g., communications of the multiple bit streams in accordance with the invention in an IBOC-FM system, a satellite broadcasting system, etc.
