Example apparatus disclosed herein are to detect a first watermark embedded in an audio stream associated with media, the first watermark embedded and detected based on a first watermarking technique; and detect a second watermark embedded in the audio stream, the second watermark embedded and detected based on a second watermarking technique. Disclosed example apparatus are also to assign the first watermark to a first monitoring track and to a second monitoring track, the first monitoring track limited to watermarks embedded in the audio stream based on the first watermarking technique, the second monitoring track limited to watermarks embedded in the audio stream based on any of the first or second watermarking techniques; group the first and second watermarks to form a media detection event when the second watermark is assigned to the second monitoring track; and cause transmission of the media detection event to a data collection facility.

Systems and methods are described to dynamically generate metadata for a live media stream. The system determines that a first user on a social media network has started a live media stream. In response, the system identifies a topic of the live media stream based on a frame of the live media stream and identifies another person featured in the frame of the live media stream based on social connections of the first user in the social media network. The system then generates a title for the live media stream based on the identified topic and the identified person, and transmits a notification to a second user that the first user is streaming live, where the notification includes the generated title.

Aspects of the subject disclosure may include, for example, receiving, for a selected channel, a first video; processing the first video for rendering on a display being viewed by a user; selecting from among a plurality of channels a subset of channels for which to pre-fetch data, the selecting being according to predictions that each channel of the subset of channels is more likely to be requested by the user than each channel of the plurality of channels that is not part of the subset; prioritizing the subset of channels such that a first channel of the subset of channels has a priority over a second channel of the subset of channels, the first channel being given the priority based upon a prediction that the first channel is more likely to be requested by the user than the second channel; pre-fetching, for the first channel, first data of a first type and second data of a second type; and pre-fetching, for the second channel, third data of the first type without pre-fetching any data of the second type. Other embodiments are disclosed.

The present disclosure describes techniques of storing and accessing multimedia files. The techniques comprise obtaining at least two multimedia files; performing format parsing for each of the at least two multimedia files separately to obtain audio encoding data, video encoding data, and container format data of each of the at least two multimedia files; storing the container format data of each of the at least two multimedia files separately, and storing one copy of the audio encoding data and video encoding data; and generating and storing index data comprising information of identifying encoding offset of the container format data, the audio encoding data, and the video encoding data in each of the at least two multimedia files, and comprising information indicative of storage address of the container format data, the audio encoding data, and the video encoding data of each of the at least two multimedia files.

A logger or annotator views video in a window or user interface (UI) of a computing device and enters time-stamped metadata or commentary; that metadata or commentary is then automatically displayed on a timeline or other time-based index in a different window or user interface of a second computing device used by a viewer or editor of that video. The metadata or commentary is represented by a marker or icon appearing on a timeline displayed in the window or user interface of a second computing device, and the metadata or commentary is shown when the viewer or editor selects that marker or icon.

This document describes marker based approaches for a CDN to monitor and report on the amount of traffic that it is serving on behalf of content providers. They are particularly useful in hybrid delivery scenarios. Hybrid delivery scenarios means that a client may obtain content, such as a given multimedia stream, from one or more servers in the CDN, or from one or more peers in a peer to peer network. The amount of data served from the peer network is referred to herein as the “offload”, as delivery of that data has been offloaded from the CDN platform.
