Caching or discarding geographic data received at a client computing device may be based on a caching policy for the geographic data. A caching policy may define conditions to process the geographic data at the client device based on several factors. For example, a current position of the client device or a position of a portion of a map displayed within a viewport of the device may cause the device to cache or discard the received geographic data. The device may determine a relationship between the viewport and the received geographic data, compare the determined relationship to the caching policy and cache or discard at least a portion of the received geographic data based on the comparison.

Caching geographic data according to server-specified policy

Embodiments relate to generation of timed text in web video. In an embodiment, a computer-implemented method generates timed text for online video. In the method, a request to play a timed text track of a video incorporated into a web video service is received from a client computing device. Prior to receipt of the request, audio of the video is processed to determine intermediate timed text data. The intermediate timed text data lacks a complete text transcription of the audio, but includes data to enable the complete text transcription to be generated when playing the video. In response to receipt of the request, a text transcription of the audio is determined using the intermediate data with an automated speech-to-text algorithm. Finally, the text transcription of the audio is sent to the client computing device for display along with the video.

Generation of timed text using speech-to-text technology and applications thereof

This invention relates to translating timed text in web video. In a first embodiment, a method automatically translates timed text for web video. The method includes receiving a request identifying a web video from a client. In response to the request, a timed text track for the web video is retrieved from a timed text database. Each timed text track in the timed text database specifies text to display at particular times in a video. Text from the timed text track is automatically translated to a target language. Finally, the translated text is sent to the client to display with the web video.
