CPC Class H04N

Methods and systems for performing analog-to-digital conversion is provided. In one example, an analog-to-digital converter (ADC) circuit comprises a leakage compensation circuit and a quantizer. The leakage compensation circuit is configured to: receive an input signal, the input signal being susceptible to a drift due to a charge leakage; receive a reference signal; and generate a leakage-compensated signal pair to compensate for the charge leakage, wherein the leakage-compensated signal pair comprises one of: (a) a leakage-compensated version of the input signal and the reference signal, (b) the input signal and a leakage-compensated version of the reference signal, or (c) a leakage-compensated version of the input signal and a leakage-compensated version of the reference signal. The quantizer is configured to perform a leakage-compensated quantization of the input signal based on the leakage-compensated signal pair to generate a digital output representing the input signal.

Methods, systems, computer-readable media, and apparatuses for providing dynamic block control of multi-bitrate video are described. In some embodiments, a computing device may determine transcoder conditions of a transcoder independent of a client device. The computing device may dynamically adjust a block size of one or more blocks of a stream based on the transcoder conditions. In some embodiments, a computing device may receive a stream. The client device may package the stream into a first packaged stream having a first block size and a second packaged stream having a second block size less than the first block size. In some embodiments, a client device may determine an actual minimum number of blocks to buffer prior to initiating content playback based on a received predicted network and/or transcoder quality of service forecast. The client device may adjust its preset minimum number of blocks to the actual minimum number of blocks.

According to one aspect of the invention, there is provided a method for supporting a relay broadcast, comprising the steps of: acquiring real-time data containing videos or audios captured or recorded in real time by at least one device, and acquiring non-real-time data containing pre-stored videos or audios; according to an editing input from a user, extracting processed non-real-time data of the same format as the real-time data from the non-real-time data, and generating metadata related to editing of a relay broadcast content containing the real-time data and the processed non-real-time data; and transmitting the real-time data and the processed non-real-time data contained in the relay broadcast content and the metadata to another device or an external server.
