Abstract: A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system; in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system; on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system; and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system.

Abstract: Disclosed are a method and electronic device for displaying play content on a smart television, which relates to the field of television service technology and solves the technical problems in the prior art that the amount of operation of a user in searching a film is large and the view experience of the user is thus influenced because there is no intelligent film recommendation function on a television terminal. Wherein, the method includes the following steps: receiving view data of a user in watching transmitted by a television terminal; predicting, according to the view data, recommended film having high correlation with the view data; and, feeding back the predicted recommended film to the television terminal so as to recommend the recommended film to the user.

Abstract: Embodiments of the present disclosure disclose a method and a device for audio data processing. The method comprises detecting a received audio data packet to determine a stream type of the audio data packet, obtaining tag data of the audio data packet when the stream type is a first stream type, determining whether the tag data belongs to preset Dolby tag information, determining the first stream type as the stream type corresponding to a Dolby DVB standard when the tag data belongs to the preset Dolby tag information, and decoding the audio data packet by means of a Dolby decoder to generate audio data.

Abstract: An embodiment of the present disclosure discloses a play method and device, wherein the method specifically comprises the steps of a player receiving a calling request from an application, wherein the calling request comprises the address parameter of multi-media contents and the position parameter of the multi-media contents; the player acquiring the multi-media contents starting from a target position corresponding to the position parameter from a server according to the address parameter; and the player playing the multi-media contents starting from the target position. The embodiment of the present disclosure may improve the efficiency of playing multi-media contents from the target position for the first time, and save memory space of an information device.

Abstract: An embodiment of the present disclosure discloses a method and a device for playing streaming media. The method comprises: pre-configuring a starting threshold for a player; when detecting a play command, acquiring time length information corresponding to buffer data, downloaded by the player; comparing the time length information with the starting threshold, determining status information of the player; and controlling the player to play streaming media according to the status information. Through pre-configuring the starting threshold for the player, the embodiment of the present disclosure avoids problem of low starting efficiency of the player caused by using a native threshold of Google, improving the starting efficiency and saving time for users.

Abstract: An embodiment of the present disclosure discloses a player-based play method and a player device. The method comprises: monitoring a player and generating a seek event of the player during the process of playing streaming media; determining a target segment of the streaming media according to the seek event, and acquiring buffer data of the target segment; and playing streaming media from the buffer data of the target segment. Through skipping over to the buffer data of the target segment, the embodiment of the present disclosure directly plays streaming media starting from buffer data of the target segment, so the player does not need to seek the key frame when adjusting the play progress, avoiding the problem of time waste caused by seeking the key frame, improving the starting efficiency of the player, and saving time.
