In a new Northern District of California complaint, Withrow Networks Inc. has accused Alphabet (Google, YouTube) (3:24-cv-03203) of infringing a single patent generally related to maintaining quality playback of audio and video content on a mobile device by automatically selecting and sequentially playing back segments of that content that are encoded in optimal formats and at optimal rates for available network bandwidth. Targeted is the YouTube service’s support of adaptive bitrate streaming using the HTTP Live Streaming (HLS) and MPEG-DASH standards.
