Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based on a determination that a segment of the fingerprint data matches a reference fingerprint corresponding with just a single channel, such as a reference fingerprint representing commercial or news programming content specific to just the single channel. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action.

Detection of whether a video is a fake video derived from an original video and altered is undertaken using a block chain that either forbids adding to the block chain copies of original videos that have been altered or indicating in the block chain that an altered video has been altered. Image fingerprinting techniques are described for determining whether video sought to be added to block chain has been altered.

Systems and methods for real-time transmission of data streams are disclosed. A controller receives data representing selected stream parameters from a browser residing on a computing device. The controller transmits the received data to a video transmitting device. A transcoder receives a first data stream generated according to the selected stream parameters from the video transmitting device. The transcoder generates a second data stream from the first data stream, the second data stream formatted for browser display; and then transmits the second data stream to the browser. A user may remotely control the video transmitting device using the browser. A user may view data streams from multiple video transmitting devices using the browser.

A video distribution server according to an embodiment of the present invention promotes the viewing of live videos. The server is communicably connected to a user terminal via a communication network and provides a live video distribution service for distributing and viewing a live video to the user via the user terminal. The server associates (adds) the tag input by the user who is viewing a live video with this live video and presents information on the live video being distributed based on the associated tag. Therefore, the user can know the current content (topic) of the live video being distributed from the information based on the tag input by the actual viewer. As a result, for example, a new user can comfortably start viewing the live video.

Shoppable video enables a viewer to identify and buy items appearing in a video. To retrieve information about the items in a frame of the video, the playback device generates a perceptual hash of that frame and uses that hash to query a first database storing perceptual hashes of different version of the video. The database query returns an identifier for the frame, which is then used to query a second database that store the item information. The results of this query are returned to the playback device, which shows them to the user, enabling the viewer to learn more about and possibly purchase the item. Using queries based on perceptual hashes of different versions of the video increases the likelihood of returning a match, despite formatting differences. And using separate hash and metadata databases makes it possible to update the metadata without changing the hashes.

Systems and methods are disclosed for detecting and removing traceable identifying audio content from electronic media content. One method includes: receiving, over a network, media content to be broadcast or distributed, the media content including audio data; determining whether the audio data of the media content includes traceable identifying audio content defined by an audio identifier; generating new audio data based on the audio data of the media content when an audio identifier is determined to be include in the audio data; removing audio data from the media content when the audio identifier is determined to be include in the audio data; adding the new audio data to the media content when the audio data is removed from the media content; and broadcasting or distributing the media content having the new audio data to one or more user devices.
