The present technology relates to a data processing apparatus and a data processing method that enable correct clock synchronization by use of clock information. The data processing apparatus receives a digital broadcast signal so as to process content included in the digital broadcast signal and clock information also included therein for use in presentation synchronization on the content and sends via a transmission path the processed content and clock information to another data processing apparatus that presents the received content. On the other hand, the another data processing apparatus receives via the transmission path the content and clock information sent from the data processing apparatus so as to process presentation synchronization on the received content on the basis of the received clock information. The present technology is applicable to data processing apparatuses configured to process content, for example.

A method for communicating with a companion device (CD) in a primary device (PD) includes receiving a broadcast signal from a broadcast station; generating a multicast advertisement message based on a simple service discovery protocol (SSDP) when the PD joins a network and sending the multicast advertisement message to a pre-defined address. Further, the multicast advertisement message includes duration information for which the multicast advertisement message is valid, further the duration information is signaled in a cache-control header. The multicast advertisement message further includes identifier information which uniquely identifies the PD, further the identifier information is signaled in a USN header, and the multicast advertisement message further includes device type information, further the device type information is signaled in a NT header.

Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.

A controlling device is provided with the ability to present personalized program guide information by using personal preferences provided to a home computing device. The personal preferences are used to filter program guide data received at the home computing device whereby the program guide data will include only programming information for user-specified sources of programming for each of plural, different user-specified periods of time. The filtered program guide data is then downloaded to the controlling device from the home computing device for use in connection with an application of the controlling device that functions to display program guide information within a display of the controlling device.

The techniques disclosed herein include a first device for reading one or more tags in metadata, the first device including one or more processors configured to receive metadata, from a second device, wirelessly connected via a sidelink channel to the first device. The one or more processors may also be configured to read the metadata, received from the second device to extract one or more tags representative of audio content, and identify audio content based on the one or more tags, and output the audio content. The first device may also include a memory, coupled to the one or more processors, configured to store the metadata.
